You're correct that the process is different to PHP. The Django
process goes something like this:
1) You set up base.html as a page template for your entire site
2) You set up home.html, extending base.html, describing your home page content
3) You set up a view in views.py that renders home.html.
4) You set up an entry in urls.py that directs the URL '/home/' to the
home view.
All of the processing (calculations, database access, etc) that would
normally happen on a PHP page happens in the view. The view produces a
context that contains the result of that processing, and the template
exposes pieces of the context.
However, if you're not doing any processing, your view could be as simple as:
from django.shortcuts import render_to_response
def home_view(request):
return render_to_response('home.html')
When someone requests a URL that has been redirected to this view,
Django responds by rendering your template, and returns the resulting
HTML to be displayed in the client browser.
This process is covered in the third tutorial:
http://www.djangoproject.com/documentation/tutorial03/
Note that for simple cases, you may be able to use a generic view.
These are views that cover simple use cases (just render a template,
render a template for a single database object, render a template for
a list of database objects, etc). Generic views are covered in the
fourth tutorial.
