#17697 closed New feature (needsinfo)

Implement a new property as list type (like extra_argument) into the ListView class

In the deprecated implementation of generic views (as functions) there was the extra_context list to pass extra arguments to the template.
Since 1.3 and the new implementation of generic views as classes doing the same need the creation of a new customized class which inherits from the ListView class as documented here (in the extra_context chapter):

It's not pythonic since the new implementation recquire more knowledge of the underlying code, and basicaly, more code to do the same! So it's a regression from my point of view.

It would be really simple to solve it keeping classes implementation by creating a new property as list type. So when instanciate the ListView class we would be able to give the extra variables as arguments.

Really need little modification to the existing code!

I think it would be a good idea to add back the extra_context kwarg, that would allow a user to give the extra context in the directly for small views.

The extra_context has to be a dict @sylock, you need to specify the key and value for that extra context.

Nevertheless, there might be a good reason why that extra_context field has been removed from the function based views to class based views, so I'd like a core developer to confirm whereas I can work on that new feature or not. I'll have to change several parts of the doc as well, so maybe I'll have to add a note in the release/1.4.txt, or 1.5-alpha-1.txt if we're not gonna add that patch in 1.4.
