Yes I see that, it's just if I don't put the custom form in it works
fine:
class DirectoryAdmin(admin.ModelAdmin):
fieldsets = [
(None, {'fields': ['cat','name','is_live']}), <--------
CAT FIELD STILL HERE AN OK
('Contact', {'fields':
['phone','mobile','fax','email','web','address']}),
('Details', {'fields':
['description','pic1','pic2','pic3','pic4']}),
]
admin.site.register(Business,DirectoryAdmin)
It suggest to me there is something in the admin code which normally
allows for this 'error' to pass. It's not a big deal, I just wondered
if it was somthing django should allow for and the design of the two
examples is inherantly the same.
