Using categories in templates
|
|
=============================
|
|
|
|
To use the template tags:::
|
|
|
|
{% import category_tags %}
|
|
|
|
Filters
|
|
*******
|
|
|
|
``tree_info``
|
|
-------------
|
|
|
|
Given a list of categories, iterates over the list, generating
|
|
two-tuples of the current tree item and a ``dict`` containing
|
|
information about the tree structure around the item, with the following
|
|
keys:
|
|
|
|
``'new_level'``
|
|
``True`` if the current item is the start of a new level in
|
|
the tree, ``False`` otherwise.
|
|
|
|
``'closed_levels'``
|
|
A list of levels which end after the current item. This will
|
|
be an empty list if the next item's level is the same as or
|
|
greater than the level of the current item.
|
|
|
|
An optional argument can be provided to specify extra details about the
|
|
structure which should appear in the ``dict``. This should be a
|
|
comma-separated list of feature names. The valid feature names are:
|
|
|
|
ancestors
|
|
Adds a list of unicode representations of the ancestors of the
|
|
current node, in descending order (root node first, immediate
|
|
parent last), under the key ``'ancestors'``.
|
|
|
|
For example: given the sample tree below, the contents of the list
|
|
which would be available under the ``'ancestors'`` key are given
|
|
on the right::
|
|
|
|
Books -> []
|
|
Sci-fi -> [u'Books']
|
|
Dystopian Futures -> [u'Books', u'Sci-fi'] |
