14283	AttributeError on admin detail page after r13708	rene.puls@…	nobody	"After updating to the latest Django version (r13840), I am getting strange errors when displaying the admin detail page for some of my models. I haven't touched my own admin or model classes for a while, so I suspect this could be a bug in a recent Django changeset. I am not very familiar with this part of Django, but it seems like the request object is not passed through correctly.

Here is the traceback:

{{{

Looking through the recent changes in Django trunk, I see that r13731 changed fields_for_model in django.forms.models, which is also in the traceback. Could this have something to do with it?

For reference, here is my model admin class:

{{{

    model = my_models.Event
    inlines = [metadata_admin.CommentInline, metadata_admin.RatingInline, metadata_admin.TagInline]
    date_hierarchy = 'created'
    raw_id_fields = ['owner', 'image', 'address']
    list_display = ['title', 'owner', 'created', 'is_active', 'is_hidden', 'community']
    list_filter = ['is_highlighted', 'community']
    fieldsets = [
        (None, {'fields': ['owner', 'community', ('start', 'end'), 'title', 'description', 'address', 'image', ('is_hidden', 'is_active'), 'is_highlighted', 'license']}),
        (u'Statistiken', {'fields': ['views', 'num_comments', 'num_ratings', 'average_rating'], 'classes': ['collapse']})
    ]
    save_on_top = True
    search_fields = ['title']
