当我为具有自定义用户模型的ForeignKey的新模型运行迁移时,出现错误:
ValueError: Lookup failed for model referenced by field test.TestModel.user: account.EmailUser
它在Django 1.7中。
我的自定义用户为apps.models.EmailUser
。
以下是相关代码:
# apps.test/models.py
from django.db import models
from django.conf import settings
class TestModel(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL)
# settings.py
AUTH_USER_MODEL = 'account.EmailUser'
INSTALLED_APPS = (
...
'apps.account',
'apps.test',
)
最后,这是迁移文件:
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.db import models, migrations
from django.conf import settings
class Migration(migrations.Migration):
dependencies = [
migrations.swappable_dependency(settings.AUTH_USER_MODEL),
]
operations = [
migrations.CreateModel(
name='TestModel',
fields=[
('id', models.AutoField(verbose_name='ID', serialize=False, auto_created=True, primary_key=True)),
('user', models.ForeignKey(to=settings.AUTH_USER_MODEL)),
],
options={
},
bases=(models.Model,),
),
]
Running migrations:

我注意到有一个测试,看它是否在django.db.migrations.state.render()中使用自定义用户模型,但是如果使用ignore_swappable = True调用render,它只会认真对待此测试不是我的情况。
任何想法?
