pip install django-submodel
# in you_app/models.py from django.db import models from submodel.fields import SubModelField # Define (field_name, model_field_instance) tuples in "fields" parameter in SubModelField, # similar as normal Model definition # If SubModelField such as pref field is newly added to an existed model, # you may want to use south to migrate the schema class UserProfile(models.Model): realname = models.CharField(max_length=100) pref = SubModelField(u'user preference', fields=( ('title', models.CharField(max_length=10)), ('color', models.IntegerField(choices=((0, 'Black'), (1, 'White')))), ('birthday_day', models.DateTimeField()), ('feel_luck', models.BooleanField(default=True))))
# in you_app/admin.py, to enable editing of sub fields of pref in Django admin from submodel.admin import SubModelFieldInlineAdmin from . models import UserProfile class PrefInilneAdmin(SubModelFieldInlineAdmin): model = UserProfile._meta.get_field('pref').submodel # TODO improve class UserProfileAdmin(admin.ModelAdmin): inlines = [PrefInilneAdmin] admin.site.register(UserProfile, UserProfileAdmin)
>>> # TODO in Python shell, the value of pref field as a model instance

more strict check such as attname confliction, for example FK field user and field user_id
