Template tag to support combining form media from multiple forms

[Bradley Ayers]

I suggest that a template tag be added that has the ability to combine the media of multiple forms within a template. This would allow someone to have multiple forms (each having similar media), without having duplicate tags added to the template output (when printing the combined form media).

Currently, the programmer would have to manually add the media within a view, and then pass the result through in a template context, in order to achieve the 'unique union' result. While browsers would not be 'dumb' enough to request the same media multiple times, I would expect that the browser should execute the contents of each file, once for each time it has been included with a script or link tag (I imagine that this could cause very undesirable side-effects, i.e. a javascript file which adds a function as an event listener each time the script is execute)

If #11687 lands (including the part supporting using the |add filter for non-integers), then this will be a non-issue.

But since that hasn't been accepted yet, I'll accept this.

If I understood right, the add filter can only add two items together, usually there are several forms and medias... It would be better to have own tag for this, so one can add several medias together not just two.

Uh, you realize you can just chain the add filter?

1.2 is feature-frozen, moving this feature request off the milestone.

Actually, may as well just mark as fixed in [12497]

What we really need, is a form/formset "binder" of some sort, so we don't have to hack dodgy stuff like this into our templates (cleans up a whole bunch of other uglies like combining errors etc too).
