Question

everyone. I’m just starting with django, so sorry for a possibly stupid question.

Imagine, I have a webpage with 3 logical pieces: content, dynamic menu, banners. It seems ok to me to have a template with something like:

{% include "banners.html" %}
{% include "menu.html" %}
{% include "content.html" %}

But then, how do I do it? Every piece has its separate logic in a separate view in its’ separate app. How do I trigger execution of all three views and render all three templates?

P.S. Is there a sourceforge-like site for django apps where I could take a look at how people are doing stuff in real projects?

Answer 1

The standard way to do it is something as follows:

Templates:

• Have a base.html that has the banners, menu and a body block which is empty.

• For each template, extend the base.html and override the body block.

  {% extends "base.html" %}
      {% block body %}
      -- Your this page's content goes here.
      {% endblock %}
  

• You can use the includes, where necessary, but prefer the extends where possible. Include was debated to be included in the template language.

Populating Context:

You now have a lot of templates with placeholders that need to be replaced with the real “context” values.

• Pass the RequestContext, that should contain many standard requirements for the template.
• For the values that you need in every template, write a template context processor.
• Those context’s that you need in this template, you populate in the view.

Using multiple app’s views:

• Most apps written for reuse will include template_name as a standard parameter, along with extra_context. You will need to call those views with these parameters.
• Some apps go out of their way, to create a lazily evaluated response (like TemplateResponse) so that you can grab the context they populate, in your view.

Django reusable apps:

Are you kidding me? They are all over the Internet!
