I am trying to implement django template tag {% domready %}{% enddomready %} that would take it's contents, remember it somewhere, and then tag {% domready_render %} that would render all that content.
It would look something like this:
{# main.html #}
<html>
...
<body>
...
<script>
(function($) {
$(document).ready(function() {
{% domready_render %}
});
})(jQuery);
</script>
</body>
</html>
{# some_other_file.html #}
{% extends main.html %}
..some html...
<a href="" id="link1">Link with onclick</a>
{% domready %}
$('#link1').click(function() { ... describe here your javascript ... });
{% enddomready %}
..some html...
<a href="" id="link2">Another with onclick</a>
{% domready %}
$('#link2').click(function() { ... describe here your another javascript ... });
{% enddomready %}
..some html...
And so my question is: how do I do that? I mean, here's what I tried to do:
@register.tag
def domready(parser, token):
nodelist = parser.parse(('enddomready',))
parser.delete_first_token()
return DomreadyNode(nodelist)
class DomreadyNode(template.Node):
def __init__(self, nodelist):
self.nodelist = nodelist
def render(self, context):
if 'dom_ready' not in context:
context['dom_ready'] = []
context['dom_ready'].append(self.nodelist.render(context))
return ''
@register.tag
def domready_render(parser, token):
return DomreadyRenderNode()
class DomreadyRenderNode(template.Node):
def render(self, context):
if 'dom_ready' in context:
return u"\n".join(context['dom_ready'])
return ''
But this context['dom_ready'] works only with same template (I mean, I can do {{ dom_ready }} in some_other_file.html, but I don't see it at main.html (maybe because they have different render contexts or what?).
Thank you.

As you guess render contexts are not shared between template files.
You can solve your problem by using a module level variable where you define your template tags.
Just add
dom_ready = []
to the top of the file, then where you have context['dom_ready'] replace it with dom_ready.
Did you know that you can call $.ready multiple times? That might be simpler and cleaner than achieving this with template tags.
