Using webapp2.uri_for in a Django template

Question

I have a GAE application that uses the webapp2 framework and the Django template engine. This setting does not support Django's built-in {% url%} template tag.

Instead of hardcode urls in my templates, I would like to use the webapp2.uri_for function in my templates. Is it possible? If so, how can I do this?

Answer 1

Try writing your own template tag, see https://docs.djangoproject.com/en/dev/howto/custom-template-tags/#writing-custom-template-tags

You may look at the source code for the tag on Django https://github.com/django/django/blob/master/django/template/defaulttags.py#L1194

Answer 2

Yes it is possible. Today I had the same question and I got the following template tag. I wanted the functionality to support the django like syntax, so it was migrated from the django url template tag.

from django import template import webapp2 register = template.Library() def uri_for(parser, token): """Webapp2 uri_for django template tag""" bits = token.split_contents() if len(bits) < 2: raise template.TemplateSyntaxError("'%s' takes at least one argument (path to a view)" % bits[0]) view_name = bits[1] as_var = None if len(bits) >= 2 and bits[-2] == 'as': as_var = bits[-1] return UriForNode(view_name, as_var) uri_for = register.tag(uri_for) class UriForNode(template.Node): """Uri for node""" def __init__(self, uri, as_var=None): self.uri = uri self.as_var = as_var def render(self, context): view = webapp2.uri_for(self.uri) if self.as_var: context[self.as_var] = view return '' return view
