MultipleObjectMixin should handle pagination prior to get_context_data

[AndrewIngram]

The current implementation of MultipleObjectMixin performs all its pagination operations as part of get_context_data. Some views might require knowledge of pagination earlier in the process, for example a ModelFormSetView I've implemented needs to know about the pagination at the point it instantiates the FormSet, which happens before get_context_data is called.

At the moment we set self.object_list to the result of self.get_queryset(), I am wondering whether self.object_list should actually be the paginated result, and we can store the unpaginated queryset (unevaluated because we won't usually need it) as self.original_object_list (or something nicer) which would also be available in the context data.

I'm concerned that any changes to accomodate this requirement might affect the API of MultipleObjectMixin in a backwards-incompatible way, so I'd like to get feedback from the core devs as to what the right way to tackle this is.

I can't see how this could be done in a backwards-compatible way, so I'm going to mark this wontfix. However, if I'm wrong -- entirely possible, I often am! -- please feel free to reopen. A patch would be nice, even an incomplete one -- it's hard to picture this stuff without a bit of code.

Thanks!

Hi,

Could you explain the reasoning behind you reopening this ticket? In particular, can you address Jacob's concerns of backwards compatibility?

Thanks.
