Passing a variable to include in extends in Django templates-CodePudding

I have the following structure of templates:

main.html

<html>
<body>
  <p>
    This works: {% block title %}{% endblock %}
  </p>

  {% include 'heading.html' with title=title %} {# but this does not work since it is not a variable #}
</body>
</html>

heading.html

<p>
  {{ title }}
</p>

page.html

{% extends 'main.html' %}

{% block title %}test title{% endblock %}

How can I pass the title from page.html to heading.html? Ideally, it should be defined as a block like now, but alternatives are also welcome. I'd like to contain the solution within the templates if possible.

CodePudding user response：

One possible solution is to split heading.html into two and add a {% block %} in-between, but this is an ugly workaround that is prone to bugs with unclosed tags.

I am searching for a better alternative.

main.html

...
{% include 'heading1.html' %} {# containing <p> #}
{% block title %}{% endblock %}
{% include 'heading2.html' %} {# containing </p> #}
...

Additionally, if white spaces are important, there has to be no new line between includes and the block.

CodePudding user response：

instead of {% include %}, you might want to use custom template tags with returning html or extension like slippers
