I'd like to propose the following changes to django.template. Some of
them are partially or fully implemented in my patch[1] for #3544.
Which of these have a chance to land in 1.0 (assumed I provide a
patch, docs and tests)?
1.) Allow recursive includes, #3544 [2]
2.) Add a template_cache to `Context`, accessible via
Context.get_template and Context.select_template. Use this in
IncludeNode, ExtendsNode, and inclusion_tag.
3.) Add a `loader` kwarg to Context to force use of a specific
templateloader (something with a get_template() method). This would
fix #2949 [3].
class PrefixLoader:
def __init__(self, prefix_list):
self.prefix_list = prefix_list
def get_template(name):
from django.template.loader import select_template
return select_template(['%s/%s' % (prefix, name) for prefix
in self.prefix_list])
tpl.render(Context({}, loader=PrefixLoader(['a', 'b', 'c'])))
This emulates select_template() for include and extends nodes.
4.) Extend with-tag syntax to allow
{% with foo as x and bar as y and ... %}
and/or {% with foo as x, bar as y, ... %}
5.) Extend include-tag syntax to allow
{% include "template" with foo as x and bar as y %}
and/or {% include "template" with foo as x, bar as y %}
This would be equivalent to {% with ... %}{% include ... %}{% endwith
%}.
6.) Add an optional `separator_chars` argument to
utils.text.smart_split and template.Token.split_contents that enables
extra delimiters
>>> map(str, smart_split('a, b,c ,d, e ,f', separator_chars=','))
['a', ',', 'b', ',', 'c', ',', 'd', ',', 'e', ',', 'f']
>>> map(str, smart_split('a=1, b=2 , c = 3', separator_chars=',='))
['a', '=', '1', ',', 'b', '=', '2', ',', 'c', '=', '3']
and use this in url, cycle, with, etc.
7.) Add a {% sub "name" %}...{% endsub %} tag that populates
Context.template_cache["name"] with its contained nodelist. {%
include "name" %} would then be used to render it.
