Question

I’m attempting to combine the admin form for the User and my UserProfile model. I found out how to do it here, which works. I have this now:

#DJANGOPROJECT/generic/admin.py
class UserProfileInline(admin.TabularInline):
    model = UserProfile

class UserAdmin(admin.ModelAdmin):
    inlines = [UserProfileInline]

admin.site.unregister(admin.models.User)
admin.site.register(admin.models.User, UserAdmin)

However, the form generated in the admin contains five instances of the user profile form, instead of one. I don’t understand why this is?

https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.InlineModelAdmin

InlineModelAdmin.extra This controls the number of extra forms the
formset will display in addition to the initial forms. See the
formsets documentation for more information.

New in Django 1.2: Please, see the release notes For users with
JavaScript-enabled browsers, an “Add another” link is provided to
enable any number of additional inlines to be added in addition to
those provided as a result of the extra argument.

The dynamic link will not appear if the number of currently displayed
forms exceeds max_num, or if the user does not have JavaScript
enabled.

InlineModelAdmin.max_num This controls the maximum number of forms
to show in the inline. This doesn’t directly correlate to the number
of objects, but can if the value is small enough. See Limiting the
number of editable objects for more information.

Try to set max_num to 1
