> Hello,

> I'm having a strange issue where I get the following exception on my
> production server, but have no issues on my dev machine:

> Django Version:1.3.1Exception Type:ImproperlyConfiguredException Value:

> EntryAdmin.form does not inherit from BaseModelForm.

> Exception Location:/home/cjfox/webapps/django_1_3_1/starship/django/contrib/admin/val idation.py
> in validate_base, line 292Python Executable:/usr/local/bin/pythonPython
> Version:2.7.3

> I have narrowed the problem down to this area of the code:

> class EntryAdminForm(forms.ModelForm):
> class Meta:
> model = Entry

> latitude = CoordinateField()
> longitude = CoordinateField()

> class EntryAdmin(admin.ModelAdmin):
> form = EntryAdminForm      ## COMMENT OUT THIS LINE MAKES THE PRODUCTION
> SERVER WORK ##
> list_display = ('title', 'location', 'pub_date', 'type', 'blogger')
> list_filter = ('blogger', 'pub_date', 'type')

> I have hit a wall with this one and could use some inspiration.
> As mentioned above commenting out form = EntryAdminForm in EntryAdmin
> makes everything work fine

> Below is more details on the error:
