Include template displaying a form - django

Question

What I want to do is include a form from a separate template at the bottom of a given page, lets say; "example.com/listdataandform/".
The form-template "form.html" displays the form as it should when the view is included in the URLConf. So I can view with "example.com/form/"
What I have so far goes something like this:
{% extends "base/base.html" %}
{% block title %} page title {% endblock %}
{% block content %}
<h2>some "scene" data</h2>
<ul>
{% for scene in scenes %}
<li>{{ scene.scene }} - {{ scene.date }}</li>
{% endfor %}
</ul>
{% include "tasks/form.html"%}
{% endblock %}
The code inside "block content" works as it should, since it is defined with it's corresponding view for the url "example.com/listdataandform/".
{% include "tasks/form.html"%}: This only displays the submit button from form.html, as expected. I realize by only doing this: {% include "tasks/form.html"%}, the corresponding view method is never executed to provide the "form"-template with data.
Is there any way to this without having to define the view to a specific pattern in urls.py, so that the form can be used without going to the that specified URL..?
So I guess the more general question is; how to include templates and provide them with data generated from a view?
Thanks.

Answer 1

For occasions like this, where I have something that needs to be included on every (or almost every) page, I use a custom context processor, which I then add to the TEMPLATE_CONTEXT_PROCESSORS in settings.py. You can add your form to the context by using this method.
Example:
common.py (this goes in the same folder as settings.py)
from myapp.forms import MyForm
def context(request):
c = {}
c['myform'] = MyForm()
return c
You can also do any processing required for the form here.
Then add it in your settings.py file:
settings.py
.
.
TEMPLATE_CONTEXT_PROCESSORS = (
'''
All the processors that are already there
'''
"myproject.common.context",
)
.
.

Indeed. You included a template, and it really means "included" - ie: "execute in the current context". The template knows nothing about your views, not even what a "view" is.
How does this help me executing the view for the included template to provide it with form data?
It doesn't. A Django "view" is not "a fraction of a template", it's really a request handler, iow a piece of code that takes an HTTP request and returns an HTTP response.
Your have to provide the form to the context one way or another. The possible places are:
in the view
in a context processor (if using a RequestContext)
in a middleware if using a TemplateResponse AND the TemplateResponse has not been rendered yet
in a custom template tag
In all cases this will just insert the form in your template's context - you'll still have to take care of the form processing when it's posted. There are different ways to address this problem but from what I guess of your use case (adding the same form and processing to a couple differents views of your own app), using a custom TemplateResponse subclass taking care of the form's initialisation and processing might just be the ticket.
