自定义用户模型在外键中不起作用

Question

我创建了一个工作正常的自定义用户模型。问题是当从外键访问用户时，它抛出我：

DETAIL: Key (author_id)=(51) is not present in table "auth_user".

我的自定义用户是 userauth，显然模型仍在寻找原始用户模型而不是自定义模型。

这是我所做的：

#settings.py
AUTH_USER_MODEL = 'userauth.UserAuth'

#models.py
from django.conf import settings
User = settings.AUTH_USER_MODEL

class Post(models.Model):
    title = models.CharField(max_length=255)
    content = models.TextField()
    author = models.ForeignKey(User, null=True,blank=True,default=None)

#admin.py
class AdminPost(admin.ModelAdmin):
   def save_model(self, request, obj, form, change):
        if getattr(obj, 'author', None) is None:
            obj.author = request.user
        obj.save()

Answer 1

我会做这样的事情（不要费心分配变量）：

models.py:

from django.conf import settings

class Post(models.Model):
    title = models.CharField(max_length=255)
    content = models.TextField()
    # You don't need 'default=None'
    author = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, blank=True)
