Its a nice feature of the dajngo admin that you can use names of model or model admin methods and plain callables in ModelAdmin.list_display. But I want show content in my custom column dependant on the logged in user. This isn't possible at the moment. But I have written a patch that passes the request object to the given callable or method, when it has the needs_request attribute and it is True.

Nitpick: I'd name the function attribute accepts_request and not needs_request -- reads better to me. Other than that looks good, but needs docs and tests.

I agree, the name sounds better, indeed.

I have updated the patch to django 1.2, renamed needs_request and have added a test, now.

i think it would be better pass request in to the constructor of ModelAdmin and create an additional method "get_list_display" so one can dynamically set the list_display fields dependent of the request (i.e have a different list_display depending on request.user or similar). It might be even better to register ModelAdmin objects dynamically based on request instead of doing all this conditional get_* overrides in ModelAdmin.
Another question would be if it's possible to limit access of users to certain AdminSites. this would be another solution:
have multiple AdminSites and register the appropriate ModelAdmins. Currently I think that users may log in to any AdminSite though, or am I mistaking?

I think there's a problem with this patch. The request parameter in lookup_field could be None, which would happen when called from AdminReadonlyField.contents(). This means that the callable may receive None in some cases, which is a shame. The callable should always receive the HTTPRequest object.

Also, I think it would make more sense (and be more consistent with the way ModelAdmin's methods work) if the request was provided as the first argument, e.g.:

    def my_function(request, ...):


    def my_method(self, request, ...):

And finally, I'd prefer the function attribute to be called takes_request, for consistency with takes_context in the inclusion_tag.
