All right, I found some sources.
http://stackoverflow.com/questions/1061279/for-the-django-admin-how-do-i-add-a-field-to-the-user-model-and-have-it-editable
http://blog.picante.co.nz/post/Subclassing-User-to-add-extra-fields-in-the-Django-Admin-Site/
By strictly holding to these, and by experimenting, I now get this:
_'StudentAdmin.fieldsets[0][1]['fields']' refers to field 'course'
that is missing from the form._
Adding a class StudentCreateForm(UserCreationForm) does not help,
either:
class StudentCreateForm(UserCreationForm):
course = forms.CharField()
class StudentAdmin(UserAdmin):
# ...
add_form = StudentCreateForm
Please, I am going crazy. There's probably a super-simple solution,
but I don't seem to find it. And I feel horribly stupid right now. And
it's several hours now, cause I can't let go - and I'm horribly tired.
Thanks,
Axel.
