A python SDK for the Transifex API (v3)

Introduction

This repository introduces 2 packages: jsonapi and transifex_api. jsonapi is an SDK library (a library that helps you build SDKs for APIs), targeted at {json:api} implementations. transifex_api uses jsonapi to create an SDK for the Transifex API, with minimal code.

Installation

git clone https://github.com/kbairak/transifex-api-python
cd transifex-api-python

python setup.py install
# or
pip install .
# or
pip install -e .  # If you want to work on the SDK's source code

`jsonapi` usage

Setting up

Using jsonapi means creating your own API SDK for a remote service. In order to do that, you need to first define an API connection type. This is done by subclassing jsonapi.JsonApi:

import jsonapi

class FamilyApi(jsonapi.JsonApi):
   HOST = "https://api.families.com"

Next, you have to define some API resource types and register them to the API connection type. This is done by subclassing jsonapi.Resource and decorating it with the connection type's register method:

@FamilyApi.register
class Parent(jsonapi.Resource):
   TYPE = "parents"

@FamilyApi.register
class Child(jsonapi.Resource):
   TYPE = "children"

Users of your SDK can then instantiate your API connection type, providing authentication credentials and/or overriding the host, in case you want to test against a sandbox API server and not the production one:

family_api = FamilyApi(host="https://sandbox.api.families.com",
                       auth="<MY_TOKEN>")

Finally the API resource types you have registered can be accessed as attributes on this API connection instance. You can either use the class's name or the API resource's type:

child = family_api.Child.get('1')
child = family_api.children.get('1')

This is enough to get you started since the library will be able to provide you with a lot of functionality based on the structure of the responses you get from the server. Make sure you define and register Resource subclasses for every type you intend to encounter, because jsonapi will use the API instance's registry to resolve the appropriate subclass for the items included in the API's responses.

Global API connection instances

You can configure an already created API connection instance by calling the setup method, which accepts the same keyword arguments as the constructor. In fact, JsonApi's __init__ and setup methods have been written in such a way that the following two snippets should produce an identical outcome:

kwargs = ...
family_api = FamilyApi(**kwargs)

kwargs = ...
family_api = FamilyApi()
family_api.setup(**kwargs)

This way, you can implement your SDK in a way that offers the option to users to either use a global API connection instance or multiple instances. In fact, this is exactly how transifex_api has been set up:

# src/transifex_api/__init__.py

import jsonapi

class TransifexApi(jsonapi.JsonApi):
    HOST = "https://rest.api.transifex.com"

@TransifexApi.register
class Organization(jsonapi.Resource):
    TYPE = "organizations"

transifex_api = TransifexApi()

# app.py (uses the global API connection instance)

from transifex_api import transifex_api

transifex_api.setup(auth="<API_TOKEN>")
organization = transifex_api.Organization.get("1")

# app.py (uses multiple custom API connection instances)

from transifex_api import TransifexApi

api_1 = TransifexApi(auth="<API_TOKEN_1>")
api_2 = TransifexApi(auth="<API_TOKEN_2>")

organization_1 = api_1.Organization.get("1")
organization_2 = api_2.Organization.get("2")

(The whole logic behind this initialization process is further explained here)

Authentication

The auth argument to JsonApi or setup can either be:

A string, in which case all requests to the API server will include the Authorization: Bearer <API_TOKEN> header

A callable, in which case the return value is expected to be a dictionary which will be merged with the headers of all requests to the API server

import datetime
import jsonapi

from family_api import FamilyApi
from .secrets import KEY
from .crypto import sign

def myauth():
    return {'x-signature': sign(KEY, datetime.datetime.now())}

family_api = FamilyApi(auth=myauth)

Custom headers

You can supply custom HTTP headers to be sent with every request to the remote server using the headers keyword argument to the JsonApi constructor or the setup method.

from family_api import FamilyApi
family_api = FamilyApi(..., headers={'X-Application': "My-client"})

Retrieval

URLs

By default, collection URLs have the form /<type> (eg /children) and item URLs have the form /<type>/<id> (eg /children/1). This is also part of {json:api}'s recommendations. If you want to customize them, you need to override the get_collection_url classmethod and the get_item_url() method of the resource's subclass:

@FamilyApi.register
class Child(jsonapi.Resource):
    TYPE = "children"

    @classmethod
    def get_collection_url(cls):
        return "/children_collection"

    def get_item_url(self):
        return f"/child_item/{self.id}"

Getting a single resource object from the API

If you know the ID of the resource object, you can fetch its {json:api} representation with:

child = family_api.Child.get("1")

The attributes of a resource object are id, attributes, relationships, links and related. id, attributes, relationships and links have exactly the same value as in the API response.

parent = family_api.Parent.get("1")
parent.id
# "1"
parent.attributes
# {'name': "Zeus"}
parent.relationships
# {'children': {'links': {'self': "/parent/1/relationships/children",
#                         'related': "/children?filter[parent]=1"}}}

child = family_api.Child.get("1")
child.id
# "1"
child.attributes
# {'name': "Hercules"}
child.relationships
# {'parent': {'data': {'type': "parents", 'id': "1"},
#             'links': {'self': "/children/1/relationships/parent",
#                       'related': "/parents/1"}}}

You can reload an object from the server by calling .reload():

child.reload()
# equivalent to
child = family_api.Child.get(child.id)

Relationships

Intro

We need to talk a bit about how {json:api} represents relationships and how the jsonapi library interprets them. Depending on the value of a field of relationships, we consider the following possibilities. A relationship can either be:

A null relationship which will be represented by a null value:

{'type': "children",
 'id': "...",
 'attributes': { ... },
 'relationships': {
     'parent': null,  # <---
     ...,
 },
 'links': { ... }}

A singular relationship which will be represented by an object with both data and links fields, with the data field being a dictionary:

{'type': "children",
 'id': "...",
 'attributes': { ... },
 'relationships': {
     'parent': {'data': {'type': "parents", 'id': "..."},     # <---
                'links': {'self': "...", 'related': "..."}},  # <---
     ... ,
 },
 'links': { ... }}

A plural relationship which will be represented by an object with a links field and either a missing data field or a data field which is a list:

{'type': "parents",
 'id': "...",
 'attributes': { ... },
 'relationships': {
     'children': {'links': {'self': "...", 'related': "..."}},  # <---
     ...,
 },
 'links': { ... }}

or

{'type': "parents",
 'id': "...",
 'attributes': { ... },
 'relationships': {
     'children': {'links': {'self': "...", 'related': "..."},    # <---
                  'data': [{'type': "children", 'id': "..."},    # <---
                           {'type': "children", 'id': "..."},    # <---
                           ... ]},                               # <---
     ... ,
 },
 'links': { ... }}

This is important because jsonapi will make assumptions about the nature of relationships based on the existence of these fields.

Fetching relationships

The related field is meant to host the data of the relationships, after these have been fetched from the API. Lets revisit the last example and inspect the relationships and related fields:

parent = family_api.Parent.get("1")
parent.relationships
# {'children': {'links': {'self': "/parent/1/relationships/children",
#                         'related': "/children?filter[parent]=1"}}}
parent.related
# {}

child = family_api.Child.get("1")
child.relationships
# {'parent': {'data': {'type': "parents", 'id': "1"},
#             'links': {'self': "/children/1/relationships/parent",
#                       'related': "/parents/1"}}}
child.related
# {parent: <Parent: 1 (Unfetched)>}

As you can see, the parent→children related field is empty while the child→parent related field is prefilled with an "unfetched" Parent instance. This happens becaue the first one is a plural relationship while the second is a singular relationship. Unfetched means that we only know its id so far. In both cases, we don't know any meaningful data about the relationships yet.

In order to fetch the related data, you need to call .fetch() with the names of the relationships you want to fetch:

child.related
# {'parent': <Parent: 1 (Unfetched)>}
(child.related['parent'].id,
 child.related['parent'].attributes,
 child.related['parent'].relationships)
# ("1", {}, {})

child.fetch('parent')  # Now `related['parent']` has all the information
child.related
# {parent: <Parent: 1>}
(child.related['parent'].id,
 child.related['parent'].attributes,
 child.related['parent'].relationships)
# ("1",
#  {'name': "Zeus"},
#  {'children': {'links': {'self': "/parent/1/relationships/children",
#                          'related': "/children?filter[parent]=1"}}})

parent.fetch('children')
parent.related
# {'children': [<Child: 1>, <Child: 2>]}
(parent.related['children'][0].id,
 parent.related['children'][0].attributes,
 parent.related['children'][0].relationships)
# ("1",
#  {'name': "Hercules"},
#  {'parent': {'data': {'type': "parents", 'id': "1"},
#              'links': {'self': "/children/1/relationships/parent",
#                        '/parents/1'}}})

Trying to fetch an already-fetched relationship will not actually trigger another request, unless you pass force=True to .fetch().

If .fetch() is only provided with one positional argument, it will return the relation:

parent = family_api.Parent.get("1")

print(parent.fetch('children')[1].name)
# "Hercules"

# Is equivalent to:

parent.fetch('children')
print(parent.related['children'][1].name)

Shortcuts

You can access all keys in attributes and related directly on the resource object:

child.name == child.attributes['name'] == "Hercules"
# True

This is very handy, both for reading and setting values to those fields, however you should be careful when setting them. If the key is not already part of attributes or relationships, the assignment will fall back to the default operation of Python objects, which is to add the key to the __dict__ attribute:

child.__dict__
# {'id': ..., 'attributes': {'name': "Hercules"}, ...}

child.name = "Achilles"
child.__dict__
# {'id': ..., 'attributes': {'name': "Achilles"}, ...}
#                                    ^^^^^^^^^^

child.hair_color = "red"
child.__dict__
# {'id': ..., 'attributes': {'name': "Achilles"}, 'hair_color': "red", ...}
#                                                 ^^^^^^^^^^^^^^^^^^^

Be careful of this because the new keys will not be included in subsequent PATCH operations to update the resource on the server. Normally you won't have to worry about this since the API server will likely have provided all attributes and relationships it is likely to accept in subsequent requests, even if their value is set to null. If you definitely want to add a new field to an object's attributes or relationships, you can always fall back to doing so directly:

child.attributes['hair_color'] = "red"
child.__dict__
# {'id': ..., 'attributes': {'name': "Hercules", 'hair_color': "red"}, ...}
#                                                ^^^^^^^^^^^^^^^^^^^

Getting Resource collections

You can access a collection of resource objects using one of the list, filter, page, include,sort, fields, extra, all and all_pages classmethods of Resource subclass.

children = family_api.Child.list()
# [<Child: 1>, <Child: 2>, ...]

Each method does the following:

list returns the first page of the results
filter applies filters; nested filters are separated by double underscores (__), Django-style

operation GET request

.filter(a=1) ?filter[a]=1

.filter(a__b=1) ?filter[a][b]=1

Note: because it's a common use-case, using a resource object as the value of a filter operation will result in using its id field
```
parent = family_api.Parent.get("1")

family_api.Child.filter(parent=parent)
# is equivalent to
family_api.Child.filter(parent=parent.id)
```
page applies pagination; it accepts either one positional argument which will be passed to the page GET parameter or multiple keyword arguments which will be passed as nested page GET parameters

operation GET request

.page(1) ?page=1

.page(a=1, b=2) ?page[a]=1&page[b]=2

(Note: you will probably not have to use .page yourself since the returned lists support pagination on their own, see below)
include will set the include GET parameter; it accepts multiple positional arguments which it will join with commas (,)

operation GET request

.include('parent', 'pet') ?include=parent,pet
sort will set the sort GET parameter; it accepts multiple positional arguments which it will join with commas (,)

operation GET request

.sort('age', 'name') ?sort=age,name
fields will set the fields GET parameter; it accepts multiple positional arguments which it will join with commas (,)

operation GET request

.fields('age', 'name') ?fields=age,name
extra accepts any keyword arguments which will be added to the GET parameters sent to the API

operation GET request

.extra(group_by="age") ?group_by=age
all returns a generator that will yield all results of a paginated collection, using multiple requests if necessary; the pages are fetched on-demand, so if you abort the generator early, you will not be performing requests against every possible page
all_pages returns a generator of non-empty pages; similarly to all, pages are fetched on-demand (in fact, all uses all_pages internally)

All the above methods can be chained to each other. So:

family_api.Child.list().filter(a=1)
# is equivalent to
family_api.Child.filter(a=1)

family_api.Child.filter(a=1).filter(b=2)
# is equivalent to
family_api.Child.filter(a=1, b=2)

family_api.Child.list().all()
# is equivalent to
family_api.Child.all()

The collections are also lazy (Django-style). You will not actually make any requests to the server until you try to access a collection like a list. So this:

def get_children(gender=None, hair_color=None):
    result = family_api.Child.list()
    if gender is not None:
        result = result.filter(gender=gender)
    if hair_color is not None:
        result = result.filter(hair_color=hair_color)
    return result

print([child.name for child in get_children(hair_color="red")])

will only make one request to the server during the execution of the list comprehension in the last line.

You can also access pagination via the has_next, has_previous, next and previous methods of a returned list (which is what all_pages and all use internally).

All the previous methods also work on plural relationships (assuming the API supports the applied filters etc on the endpoint specified by the related link of the relationship).

print(parent.fetch('children').filter(name="Hercules")[0].name)

# Will print the names of the *first page* of the children
print([child.name for child in parent.children])
# Will print the names of the *all* the children
print([child.name for child in parent.children.all()])

Prefetching relationships with `include`

If you use the include method on a collection retrieval or if you use the include keyword argument on .get() (and if the server supports it), the included values of the response will be used to prefill the relevant fields of related:

child = family_api.Child.get("1", include=['parent'])
child.parent.name  # No need to fetch the parent
# "Zeus"

children = family_api.Child.list().include('parent')
[child.parent.name for child in children]  # No need to fetch the parents
# ["Zeus", "Zeus", ...]

In case of a plural relationships with a list data field, if the response supplies the related items in the included section, these too will be prefilled.

parent = family_api.Parent.get("1", include=['children'])

# Assuming the response looks like:
# {'data': {'type': "parents",
#           'id': "1",
#           'attributes': ...,
#           'relationships': {'children': {'data': [{'type': "children", 'id': "1"},
#                                                   {'type': "children", 'id': "2"}],
#                                          'links': ...}}},
#  'included': [{'type': "children",
#                'id': "1",
#                'attributes': {'name': "Hercules"}},
#               {'type': "children",
#                'id': "2",
#                'attributes': {'name': "Achilles"}}]}

[child.name for child in parent.children]  # No need to fetch
# ["Hercules", "Achilles"]

Getting single resource objects using filters

Appending .get() to a collection will ensure that the collection is of size 1 and return the one resource instance in it. If the collection's size isn't 1, it will raise a jsonapi.DoesNotExist or jsonapi.MultipleObjectsReturned exception accordingly (both are subclasses of jsonapi.NotSingleItem).

child = family_api.Child.filter(name="Bill").get()

The Resource's .get() classmethod, which we covered before, also accepts keyword arguments, if a positional id argument isn't used. Calling it this way, will apply the filters and use the collection's .get() method on the result.

child = family_api.Child.get(name="Bill")
# is equivalent to
child = family_api.Child.filter(name="Bill").get()

Note: The Resource's .get() classmethod accepts an include keyword argument as well, so be careful of naming conflicts if you want to use a filter called 'include'

# Don't do this
family_api.Child.get(name="Bill", include="parent")
# equivalent to
family_api.Child.filter(name="Bill").include('parent').get()

# Do this instead
child = family_api.Child.filter(name="Bill", include="parent").get()

Editing

Saving changes

After you change some attributes or relationships, you can call .save() on an object, which will trigger a PATCH request to the server. Because usually the server includes immutable fields with the response (creation timestamps etc), you don't want to include all attributes and relationships in the request. You can specify which fields will be sent with:

.save()'s positional arguments, or
the EDITABLE class attribute of the Resource subclass

child = family_api.Child.get("1")
child.name += " the Great"
child.save('name')

# or

@FamilyApi.register
class Child(Resource):
    TYPE = "children"
    EDITABLE = ['name']

child = family_api.Child.get("1")
child.name += " the Great"
child.save()

Because setting values right before saving is a common use-case, .save() also accepts keyword arguments. These will be set on the resource object, right before the actual saving:

child.save(name="Hercules")
# is equivalent to
child.name = "Hercules"
child.save('name')

Creating new resources

Calling .save() on an object whose id is not set will result in a POST request which will (attempt to) create the resource on the server.

parent = family_api.Parent.get("1")
child = family_api.Child(attributes={'name': "Hercules"},
              relationships={'parent': parent})
child.save()

After saving, the object will have the id returned by the server, plus any other server-generated attributes and relationships (for example, creation timestamps).

There is a shortcut for the above, called .create()

parent = family_api.Parent.get("1")
child = family_api.Child.create(attributes={'name': "Hercules"},
                     relationships={'parent': parent})

Note: for relationships, you can provide either a resource instance, a "Resource Identifier" (the 'data' value of a relationship object) or an entire relationship from another resource. So, the following are equivalent:

# Well, almost equivalent, the first example will trigger a request to fetch
# the parent's data from the server
child = family_api.Child.create(attributes={'name': "Hercules"},
                                relationships={'parent': family_api.Parent.get("1")})
child = family_api.Child.create(attributes={'name': "Hercules"},
                                relationships={'parent': family_api.Parent(id="1")})
child = family_api.Child.create(attributes={'name': "Hercules"},
                                relationships={'parent': {'type': "parents": 'id': "1"}})
child = family_api.Child.create(attributes={'name': "Hercules"},
                                relationships={'parent': {'data': {'type': "parents": 'id': "1"}}})

This way, you can reuse a relationship from another object when creating, without having to fetch the relationship:

new_child = family_api.Child.create(attributes={'name': "Achilles"},
                                    relationships={'parent': old_child.parent})

Magic kwargs

When making new (unsaved) instances, or when you create instances on the server with .create(), you can supply any keyword argument apart from id, attributes, relationships, etc and they will be interpreted as attributes or relationships. Anything that looks like a relationship will be interpreted as such while everything else will be interpreted as an attribute.

Things that are interpreted as relationships are:

Resource instances
Resource identifiers - dictionaries with 'type' and 'id' fields
Relationship objects - dictionaries with a single 'data' field whose value is a resource identifier

So

family_api.Child(name="Hercules")
# is equivalent to
family_api.Child(attributes={'name': "Hercules"})

family_api.Child(parent={'type': "parents", 'id': "1"})
# is equivalent to
family_api.Child(relationships={'parent': {'type': "parents", 'id': "1"}})

family_api.Child(parent=family_api.Parent(id="1"))
# is equivalent to
family_api.Child(relationships={'parent': family_api.Parent(id="1")})

If you are worried about naming conflicts, for example if you want to have a relationship called 'attributes', an attribute that looks like a relationship and an attribute called 'id', you should fall back to using 'attributes' and 'relationships' directly.

# Don't do this
child = family_api.Child(attributes={'type': "attributes", 'id': "1"},
                         stats={'type': "stats", 'id': "2"},
                         id="3")
child.to_dict()
# {'type': "children",
#  'attributes': {'type': "attributes", 'id': "1"},
#  'relationships': {'stats': {'data': {'type': "stats", 'id': "2"}}},
#  'id': "3"}

# Do this instead
child = family_api.Child(relationships={'attributes': {'type': "attributes", 'id': "1"}}
                         attributes={'stats': {'type': "stats", 'id': "2"}, 'id': "3"})
child.to_dict()
# {'type': "children",
#  'attributes': {'stats': {'type': "stats", 'id': "2"},
#                 'id': "3"},
#  'relationships': {'attributes': {'data': {'type': "attributes", 'id': "1"}}}}

Note: .to_dict() returns the {json:api} representation of the Resource instance, ie what the payload to the server would be if we called .save() on it

Client-generated IDs

Since .save() will issue a PATCH request when invoked on objects that have an ID, if you want to supply your own client-generated ID during creation, you have to use .create(), which will always issue a POST request.

family_api.Child(attributes={'name': "Hercules"}).save()
# POST: {data: {type: "children", attributes: {name: "Hercules"}}}

family_api.Child(id="1", attributes={'name': "Hercules"}).save()
# PATCH: {data: {type: "children", id: "1", attributes: {name: "Hercules"}}}

family_api.Child.create(attributes={'name': "Hercules"})
# POST: {data: {type: "children", attributes: {name: "Hercules"}}}

family_api.Child.create(id="1", attributes={'name': "Hercules"})
# POST: {data: {type: "children", id: "1", attributes: {name: "Hercules"}}}
# ^^^^

Deleting

Deleting happens simply by calling .delete() on an object. After deletion, the object will have the same data as before, except its id will be set to None. This happens in case you want to delete an object and instantly re-create it, with a different ID.

child = family_api.Child.get("1")
child.delete()

# Will create a new child with the same name and parent as the previous one
child.save('name', 'parent')

child.id in (None, "1")
# False

Editing relationships

Singular relationships

Changing a singular relationship can happen in two ways (this also depends on what the server supports).

child = family_api.Child.get("1")

child.parent = new_parent
child.save('parent')

# or

child.change('parent', new_parent)

The first one will send a PATCH request to /children/1 with a body of:

{"data": {"type": "children",
          "id": "1",
          "relationships": {"parent": {"data": {"type": "parents", "id": "2"}}}}}

The second one will send a PATCH request to the URL indicated by child.relationships['parent']['links']['self'], which will most likely be something like /children/1/relationships/parent, with a body of:

{"data": {"type": "parents", "id": "2"}}

If you want to use the first way, you could also change the relationship directly:

child.relationships['parent'] = {'data': {'type': "parents", 'id': "2"}}

child.save('parent')

However, this poses a danger. relationships and related are supposed to be in sync with each other and, if you change one or the other directly, they may stop being in sync which may generate some confusion later. A successful .save() will rewrite the relationships so you should be OK. However, if you want to be safe, you should use the .set_related() method to edit relationships:

child.set_related('parent', family_api.Parent(id="2"))

or use the relationship's name shortcut:

child.parent = family_api.Parent(id="2")

(the shortcut uses .set_related() during assignment internally anyway)

Plural relationships

For changing plural relationships, you can use one of the add, remove and reset methods:

parent = family_api.Parent.get("1")
parent.add('children', [new_child, ...])
parent.remove('children', [existing_child, ...])
parent.reset('children', [child_a, child_b, ...])

These will send a POST, DELETE or PATCH request respectively to the URL indicated by parent.relationships['children']['links']['self'], which will most likely be something like /parents/1/relationships/children, with a body of:

{"data": [{"type": "children", "id": "1"},
          {"type": "children", "id": "2"},
          {"...": "..."}]}

Similar to the case when we were instanciating objects with relationships, the values passed to the above methods can either be resource objects, "resource identifiers" or entire relationship objects:

parent.add('children', [family_api.Child.get("1"),
                        family_api.Child(id="2"),
                        {'type': "children", 'id': "3"},
                        {'data': {'type': "children", 'id': "4"}}])

This way, you can easily use another object's plural relationship:

parent_a = family_api.Parent.get('1')
parent_b = family_api.Parent.get('2')

# Make sure 'parent_b' has the same children as 'parent_a'
parent_b.reset('children', list(parent_a.fetch('children').all()))

Bulk operations

Resource subclasses provide the bulk_delete, bulk_create and bulk_update classmethods for API endpoints that support such operations. The arguments to these class methods are quite flexible. Consult the docstrings of each method for their types or see the following examples.

Furthermore, bulk_update accepts a fields keyword argument with the attributes and relationships of the objects it will attempt to update.

# Bulk-create
family_api.Child.bulk_create([
   family_api.Child(attributes={'name': "One"}, relationships={'parent': parent}),
   {'attributes': {'name': "Two"}, 'relationships': {'parent': parent}},
   ({'name': "Three"}, {'parent': parent}),
])

# Bulk-update
child_a = family_api.Child.get("a")
child_a.married = True

family_api.Child.bulk_update(
   [child_a,
    {'id': "b", 'attributes': {'married': True}},
    ("c", {'married': True}), "d"],
   fields=['married'],
)

# Bulk delete
child_a = family_api.Child.get("a")
family_api.Child.bulk_delete([child_a, {'id': "b"}, "c"])

parent = family_api.Parent.get("1")
family_api.Child.delete(list(parent.children.all()))

For more details, see our bulk oprations {json:api} profile.

Form uploads, redirects

If an endpoint accepts other content-types apart from application/vnd.api+json during creation (most likely a multipart/form-data for file uploads), you can perform such requests using the .create_with_form classmethod. The keyword arguments you provide will be passed to the requests library, giving you complete control over the request you want to perform.

According to {json:api}'s recommendations, an endpoint may return a 303-redirect response. If that's the case for a .get() or .reload() call, the object's id, attributes, links, relationships and related attributes will be empty. What will be there is a redirect attribute set to the response's Location header's value. Calling .follow() on such an object will retrieve that location and process the response using the appropriate class.

Given these two mechanisms, here is how you might go about performing a source file upload in Transifex API:

@TransifexApi.register
class TxResource(Resource)
    TYPE = "resources"

@TransifexApi.register
class ResourceStringsAsyncUpload(Resource)
    TYPE = "resource_strings_async_uploads"

@TransifexApi.register
class ResourceString(Resource)
    TYPE = "resource_strings"

transifex_api = TransifexApi(...)

resource = transifex_api.TxResource.get(...)
with open(...) as f:
    upload = transifex_api.ResourceStringsAsyncUpload.create_with_form(
        data={'resource': resource.id},
        files={'content': f},
    )
while True:
    if upload.redirect:
        strings = upload.follow()
        break
    sleep(5)
    upload.reload()

`transifex_api` usage

As we said before, the transifex_api package has minimal code as almost the entire functionality is implemented in jsonapi. transifex_api simply hosts the Resource subclasses. You can find them here and cross-check with the API specification. Assuming you understand how the jsonapi package works, you should be able to work with transifex_api.

Sample usage:

import os
from transifex_api import transifex_api

# There is a default host for transifex
transifex_api.setup(auth=os.environ['API_TOKEN'])

organizations = {organization.slug: organization
                 for organization in transifex_api.Organization.all()}
organization = organizations['kb_org']

project = transifex_api.Project.get(organization=organization, slug="kb1")

resource = Resource.get(project=project, slug="fileless")

languages = {language.code: language
             for language in project.fetch('languages').all()}
language = languages['el']

translations = transifex_api.ResourceTranslation.\
    filter(resource=resource, language=language).\
    include('resource_string')
translation = translations[0]

# Let's translate something
if not translation.strings:
    source_string = translation.resource_string.strings['other']
    translation.strings = {'other': source_string + " in greeeek!!!"}
if not translation.reviewed:
    translation.reviewed = True
translation.save('strings', 'reviewed')

Testing

To run the tests:

mkvirtualenv transifex_sdk
pip install -e .
pip install -r requirements/testing.txt
make test

There are several variations on test commands, most targeted towards active development:

make test: Run tests in multiple python versions using tox
make covtest: Display coverage information using pytest-cov
make debugtest: Disable screen capture (with -s option to pytest) so that you can invoke a debugger while the tests are running
make watchtest: Invoke the tests with pytest-watch so that they rerun every time a source python file in the repository changes
