Django installing multiple apps on the same page

Question

I'm very new to Django and definitely not very experienced.

Anyhow, I've startet my own site on the local network and succesfully created an app using Django 1.4. But when I tried to start another app, it only seems to show up on my website under some (in my eyes) specieal circumstances.

Whenever my urls.py file looks like this:

    urlpatterns = patterns('',
        url(r'^$', 'myapp1.views.home1', name='home1'),
        url(r'^$', 'myapp2.views.home2', name='home2'),

The first app is shown on the page, but when I switch them around the second app is shown on the page:

    urlpatterns = patterns('',
        url(r'^$', 'myapp2.views.home2', name='home2'),
        url(r'^$', 'myapp1.views.home1', name='home1'),

as I said, I'm no very experience, so if you need me to provide more information let me know.

Answer 1

Django works by matching a URL pattern to some code that you have written in views.py.

In your case, you are pointing the same pattern (^$) to two view methods. Django will stop when it finds a match, so when you switch the patterns around, it will always match the first entry in the list.

If you change your patterns to:

urlpatterns = patterns('',
        url(r'^/two$', 'myapp2.views.home2', name='home2'),
        url(r'^$', 'myapp1.views.home1', name='home1'),

Now when you type http://localhost:8000/two home2 will be executed, and when you type http://localhost:8000/ home1 will be executed.
