django sekizai {% addtoblock %} tag is not working properly

问题

I'm trying to implement django sekizai app. It is duplicating the js files that i'm adding.

base template:

{% load sekizai_tags %}
...
{% render_block "my_js" %}

template that is using this base:

{% load sekizai_tags %}
<div id="a1" >
    {% addtoblock "my_js" %}
        <script type="text/javascript" src="{{ MEDIA_URL }}js/my_js.js"></script>
    {% endaddtoblock %}
</div>
{% addtoblock "my_js" %}
    <script type="text/javascript" src="{{ MEDIA_URL }}js/my_js.js"></script>
{% endaddtoblock %}

Now here the rendered template has rendered twice.But when I tried adding the same script within the div it wasn't duplicated. Would appreciate if someone can shed some light on this!

Also when i try to use {% addtoblock %} in a template rendered by a template tag the script goes missing (It is neither included nor it stays in that template).

Note: The template tags, render_block and addtoblock, are from the django-sekizai package.

回答1:

{% addtoblock %} and {% endaddtoblock %} have to be inside of a block in templates that inherit another template.

# base.html
<html>
    ...
    {% render_block 'js' %}
    {% block js %}{% endblock %}
</html>


# some-page.html
{% inherits 'base.html' %}

{% block js %}
    {% addtoblock 'js' %}
        <script type="text/javascript" ... />
    {% endaddtoblock %}
{% endblock %}

Hope that helps you out.

回答2:

{% addtoblock %} inside the template (something.html) from an inclusion tag:

from django import template
from django.conf import settings

register = template.Library()

@register.inclusion_tag('something.html', takes_context=True)
def render_something(context, some_arg):
    sezikai_ctx_var = getattr(settings, 'SEKIZAI_VARNAME', 'SEKIZAI_CONTENT_HOLDER')
    attrs = {
        'some_arg': some_arg,
        sezikai_ctx_var: context[sezikai_ctx_var]
    }
    return attrs
