I would like to provide the same content inside 2 different base files.
So, I'm trying to do this:
page1.html:
{% extends "base1.html" %}
{% include "commondata.html" %}
page2.html:
{% extends "base2.html" %}
{% include "commondata.html" %}
The problem is that I can't seem to use both extends and include. Is there some way to do that? And if not, how can I accomplish the above?
commondata.html overrides a block that is specified in both base1.html and base2.html
The purpose of this is to provide the same page in both pdf and html format, where the formatting is slightly different. The above question though simplifies what I'm trying to do so if I can get an answer to that it will solve my problem.
When you use the extends template tag, you're saying that the current template extends another -- that it is a child template, dependent on a parent template. Django will look at your child template and use its content to populate the parent.
Everything that you want to use in a child template should be within blocks, which Django uses to populate the parent. If you want use an include statement in that child template, you have to put it within a block, for Django to make sense of it. Otherwise it just doesn't make sense and Django doesn't know what to do with it.
The Django documentation has a few really good examples of using blocks to replace blocks in the parent template.
