示例1: import_taglib
# 需要导入模块: from django.template.base import Library [as 别名]
# 或者: from django.template.base.Library import tags[name_to_use] [as 别名]
def import_taglib(parser, token):
"""
Extends Django's default {% load %} templatetag as a new tag called {% import %},
which allows for extended functionality (while being backwards compatible).
Load a tag library from a particular app:
{% import myapp:mytaglib %}
Load a particular tag from a particular app:
{% import mytag from myapp:mytaglib %}
Load a particular tag from a particular app and rename:
{% import mytag from myapp:mytaglib as othername %}
**Note**: you cannot rename multiple tags, so if you do:
{% import mytag myothertag from myapp:mytaglib as othername %}
then only the last tag will be using othername, and the first one won't
be imported.
