django：LookupError：App＆＃39;没有＆＃39;模特＆＃39;模型

Question

我正在使用https://bixly.com/blog/awesome-forms-django-crispy-forms/，尝试使用django crispy表单设置bootstrap 3表单。

在app1 / models.py中，我已经设置了表单：

from django.db import models
from django.contrib.auth.models import User
from django.contrib.auth.models import AbstractUser
from django import forms


class User(AbstractUser):

    # Address
    contact_name = models.CharField(max_length=50)
    contact_address = models.CharField(max_length=50)
    contact_email = models.CharField(max_length=50)
    contact_phone = models.CharField(max_length=50)
    ......

请注意我还没有创建任何数据库表。在这个阶段我不需要它们。我只是想让表单正常工作。当我跑步时，我得到：

    cls = apps.get_model(settings.AUTH_USER_MODEL)
  File "C:\lib\site-packages\django\apps\registry.py", line 202, in get_model
    return self.get_app_config(app_label).get_model(model_name.lower())
  File "C:\lib\site-packages\django\apps\config.py", line 166, in get_model
    "App '%s' doesn't have a '%s' model." % (self.label, model_name))
LookupError: App 'app1' doesn't have a 'models' model.

我该如何解决这个问题？

Answer 1

AUTH_USER_MODEL设置的格式应为<app name>.<model>。您的型号名称为User，而非model，因此您的设置应为：

AUTH_USER_MODEL = 'app1.User'

您还应该从User删除以下models.py导入内容。您只需导入AbstractUser。

from django.contrib.auth.models import User
