django tutorial part 2: clarification about INSTALLED APPS

[Asi Dimbez]

Hi,

I'm a newbie, there is thing not clear to me in the tutorial, part 2. 

I left part 1 with poll app working ok.

In the tutorial, part 2, I read about INSTALLED_APPS :" That holds the names of all Django applications that are activated in this Django instance.."

Now, poll app worked from part 1 even without being listed in INSTALLED_APPS hence a simple app doesn't need to lie there in order to work.

So I thought that INSTALLED_APPS holds all the apps which use a database, but I also read:

Some of these applications make use of at least one database table

So it seems that there can be even apps listed in INSTALLED_APPS which don't use any database.

So, my question is: what are axactly those apps that need to be listed in INSTALLED_APPS?

Thanks

Asi

I can't remember the polls app clearly but I don't think you were using
the web framework part of Django to get it working. If I recall, it was
all in the console because the focus was only object/relational mapping
and database.

True.

Apps which Django needs to know about in the web framework. In other
words, apps with models, urls, views and templates or which have
utilities called from such apps using the app_name as a namespace.
