django-quicktag

Easy templatetags for Django

Easily creates templatetags with flexible arguments and keyword arguments.

{% write_your_tags with_variables|filters:"args", and="keywords" %}

Features

• python-like syntax for arguments and keyword arguments
• expands variables and applies template filters
• boilerplate-free: write a function that returns a string and decorate
• configurable access to the template context

Installation

sudo pip install django-quicktag

Simple Usage

# myapp/templatetags/mytags.py
from django import template
from quicktag import quicktag

register = template.Library()

@register.tag
@quicktag() # Don't forget parenthesis
def tag_without_context(*args, **kwargs):
    ...

@register.tag
@quicktag(takes_context=True)
def tag_with_context(context, *args, **kwargs):
    ...

Sample templatetags

Simple argument and simple rendering

Basic example that renders the current date in some format:

# ...
@register.tag
@quicktag() # Don't forget parenthesis
def quicktoday(date_format):
    """
    Example: {% quicktoday '%d/%m/%Y' %}
    """
    from datetime import date
    return date.today().strftime(date_format)

Taking and changing context (no rendering)

Takes the template context and sets/updates new variables using keyword arguments.

# ...
@register.tag
@quicktag(takes_context=True)
def set_vars(context, **kwargs):
    """
    Example:
    {{ var1 }} / {{ var2 }}
    {% set_vars var1="modified var1",var2="modified var2" %}
    {{ var1 }} / {{ var2 }}
    """
    context.update(kwargs)
    return ''

Rendering any HTML tag with attributes

Takes an HTML tag name and renders keyword arguments as attributes:

# ...
@register.tag
@quicktag()
def html_tag(tagname, **kwargs):
    """
    Example: {% html_tag "img",src="/media/logo.png",width="100" height="50" %}
    """
    return '<%s %s />' % (tagname, ['%s="%s"' k,v for k,v in kwargs.items()])

Using render_to_string

Includes the template loader's first match from a list of possible templates:

# ...
@register.tag
@quicktag(takes_context=True)
def include_any(context, *template_list):
    """
    Example: {% include_any variable_template,"fallback_template.html" %}
    """
    return render_to_string(template_list, context)
