Django error: 'QueryDict' object has no attribute '_meta'

I am very new to django so this is probably a noob question开发者_Python百科. I am trying to reuse django admin's change list view. I've created a admin model and want to provide the changelist template a list of these objects. In my view I have:

def placements(request):
    partner_id = request.session.get('partner_id', 0)
    self = PlacementAdmin(request.GET, Placement.objects.filter(partner=partner_id))
    return render_to_response('publisher/placement/change_list.html', {'cl': self})

I get this error when I try to hit this function from a browser: 'QueryDict' object has no attribute '_meta' Could anyone tell me what the error is or provide an easier way to accomplish this in case I am on the wrong track completely.

Heres the complete trace:

It's best to post the traceback error when posting a question!

That said, the error comes from you passing request.GET to a ModelAdmin admin object which isn't expecting it.

You have a long road of troubles ahead of you though, as you're trying to use the magical change_list view template which is operated on by a collection of even more magical, undocumented template tags, which just doesn't normally appear in the same sentence as new to django.

I think you're on the wrong track simply because django's admin is not easy to hack into.

At a minimum, you'd have to pass in your template a ChangeList object for the cl variable.

If you really want to do this, the only advice I can give is to take a look at django.contrib.admin.options.ModelAdmin.changelist_view() since that's what you're trying to replicate.

Seriously though I'd like to talk you out of this. Django's actually really fun to work with!
