@@ -162,6 +162,31 @@ A new helper function,
``template.Library`` to ease the creation of template tags that store some
data in a specified context variable.
``*args`` and ``**kwargs`` support for template tag helper functions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
:ref:`simple_tag<howto-custom-template-tags-simple-tags>`, :ref:`inclusion_tag
<howto-custom-template-tags-inclusion-tags>` and the newly introduced
:ref:`assignment_tag<howto-custom-template-tags-assignment-tags>` template
helper functions may now accept any number of positional or keyword arguments.
For example:
.. code-block:: python
@register.simple_tag
def my_tag(a, b, *args, **kwargs):
warning = kwargs['warning']
profile = kwargs['profile']
...
return ...
Then in the template any number of arguments may be passed to the template tag.
For example:
.. code-block:: html+django
{% my_tag 123 "abcd" book.title warning=message|lower profile=user.profile %}
``truncatechars`` template filter
