0.10.2

  • [Fix] Do not parse semicolons in urlencoded POST body

0.10.1

  • [Fix] error_to_dict fail on BadField error.

0.10

  • [Break] covador.aiohttp.AsyncValidationDecorator removed in favour of unified sync/async through AST transformation (_async/gen_validator.py).
  • [Feature] python 3.8 support.
  • [Feature] view function can raise covador.errors.Invalid exception and covador will handle it with an appropriate error handler.
  • [Fix] use AST transformer to get legacy and new style coroutines for covador.aiohttp.get_form and covador.aiohttp.get_json. Fixes @coroutine deprecation warning in python3.8.

0.9.26

  • [Fix] Right hand pipe must coerce value to item.

0.9.25

  • [Feature] web frameworks in integration tests were updated.
  • [Fix] aiohttp query_string decorator led to deprecation error.

0.9.24

  • [Fix] length(min=N) was treated as length(N) -- sequence must have length of N exactly. This is confusing and wrong behavior.

0.9.23

  • [Refactor] extract item getter entity from Map.
  • [Feature] soft map type. It can describe dicts with unknown keys.
  • [Fix] One can pass pipes with maps into schema.

0.9.22

  • Schema introspection for view functions

    import covador
from covador.flask import query_string

@query_string(boo=int)
def view():
    pass

print(view.schema.items)
# {'boo': <covador.types.item object at 0x7fb2c9dad208>}

0.9.21

  • [Feature] python 3.7 support
  • [Optimization] schema(...) tries to return Map with merged items instead of MergedMap.

0.9.20

  • [Break] rparams renamed to args.
  • [Fix] aiohttp and sanic.
  • [Refactor] Real integration tests with whole app starting.

0.9.18

  • [Feature] python 2.6 support
  • [Fix] missing pipeable support for oneof.
  • [Fix] django support

0.9.17

  • [Fix] Ensure List validator for items with multi=True.

0.9.16

  • [Break] IMPORTANT!! empty_is_none consider empty strings only. For example, schema(price=int)({'price': 0}) does not raises Required Item exception anymore.
  • [Feature/Break] Strict parsing for application/x-www-form-urlencoded, multipart/form-data and application/json content types.
  • [Feature] covador.vdecorator.mergeof validation decorator compositor. For example, all params decorators are mergeof(query_string, form).
  • [Feature] Support for multipart/form-data content type.
  • [Feature] Assume empty dictionary for json_body in case of empty request body.
  • [Feature] covador.check allows to create validators from boolean functions.
  • [Feature] Log invalid inputs for validation decorators. One can use COVADOR_DEBUG environment variable to enable stack traces in logs.
  • [Refactor] Extract covador.vdecorator module from covador.utils.

0.9.15

  • [Break] empty_is_none=True for covador.item to synchronize behavior with covador.opt. Introduce similar covador.nitem. Change allows to make explicit empty values acceptance.

0.9.14

  • [Fix] Common item declarations lead to field erasure in schema.

0.9.13

  • [Feature] Add support for Sanic.

0.9.12

  • [Feature] KeyVal validator for typed mappings like Map<T1,T2>.

0.9.11

  • [Fix] reimplementation of parse_qs to deal with bug in py3.

0.9.10

  • [Fix] UnicodeDecodeError in parse_qs under python3.

0.9.8

  • [Break] rename t_date, t_time, t_datetime into Date, Time, DateTime respectively.
  • [Feature] aiohttp.rparams now uses request.match_info.

0.9.7

  • [Break] length validator with single argument asumes min=max, so length(3) is equivalent for length(3, 3).
  • [Feature] numbers validator which can extract number sequences from strings. Can be used to extract digits from phone numbers.

0.9.6

  • [Feature] Naive t_datetime, t_date and t_time validators. Completely timezone-unaware. Suitable only for simple cases when only a local time is needed. And you always can apply pytz for these values.

  • [Feature] timestamp validator to deal with unix timestamps in seconds and milliseconds and treat it like UTC and local values.

  • [Feature] Error handler wrapper allows to override default error handlers without touching decorators:

    from covador import flask

@flask.error_hanler.set
def custom_error_handler(ctx):
    print ctx.exception
    ctx.reraise()  # reraise exception with original traceback

0.9.5

  • [Break] Changed argument order for item. default is on a second position now, so one can use opt(int, 0) instead of opt(int, default=0). Default values are more common case then custom source keys.
  • [Feature] oneof validator to select suitable alternative.
  • [Feature] dest and src (an alias for source_key) parameters for item, it controls a destination and a source key value for a Map.
  • [Feature] dpass decorator helper allows to use complex expression inline.
  • [Feature] _ keyword argument for schema constructor to attach a validation chain to a resulted schema. Can be used instead of dpass.
  • [Feature] Public properties for built-in validation exceptions.
  • [Fix] Fixed covador.aiohttp.params decorator.
  • [Fix] Incorrect schema for rparams for all supported frameworks.

0.9.1

  • [Feature] Exception hierarchy for built-in checkers.

0.9.0

  • Drop covador.aiohttp.m_* decorators in favor simple query_string/form/etc... Support for CBV are kept.

  • Added json_body for django, tornado and aiohttp.

  • Ability to customize error handler via .on_error validator decorator method:

    from covador import flask

def error_handler(ctx):
    print ctx.exception
    ctx.reraise()  # reraise exception with original traceback

custom_query_string = flask.query_string.on_error(error_handler)

  • Pipeable decorators:

    from covador import wrap_in, flask

pager = (flask.query_string(offset=int, limit=int)
         | (lambda d: Paginator(d['limit'], d['offset']))
         | wrap_in('pager'))

@pager
def view(pager):
    # use pager...
    pass
