Django ForeignKey field name “check” raises SystemCheckError

The Django docs (https://docs.djangoproject.com/en/1.11/topics/db/models/#field-name-restrictions) state there are only two restrictions on model field names: 1. A field name cannot be a Python reserved word 2. A field name cannot contain more than one underscore in a row However, give

Django ForeignKey versus ManyToManyField

Hi I have two models, a Customer model and a WishListItem model (which stores products). I have option of either having a ManyToManyField in Customer to WishListItem, or I can have a customer ForeignKey to customer for each WishListItem. Which one will be more efficient ? Thanks -- You recei

Django ForeignKey which does not require referential integrity?

For the record, I've looked deep into django's code to find what needs to be done, but I think that simply subclassing ForeignKey will not be enough. NB: I use South for managing my database schema, so I figure I'll need to do something about that too. But it may be out of the subject here :) -

Django ForeignKey to_field vs. db_column

I'm working on some models for a legacy database structure, and am having a road_block with Foreign Keys and non-conventional names. As I understand it, if in my model I have something like: something = ForeignKey(something) then django will look for the something_id field in my table when look

Hi Nathan, I did manage.py syncdb with the table still not existing. I did manage.py sqlall myapps when saw that the foreign key was not created. here is my actual source code. from django.db import models from django.contrib.auth.models import User as AdminUser # Create your models here. DEPA

Re: django foreignkey

manage.py syncdb won't add new fields to the database if the table already exists. You'll have to do this yourself. See manage.py sqlall for some help. Otherwise, if you have: user = models.ForeignKey(User), then look for a field named user_id in your table. Nathan Ostgard On Jul 18, 9
