Question

我有一个自定义用户模型，其中主键是email字段，这也是USERNAME_FIELD和REQUIRED_FIELD。我的用户模型是这样的：

class User(AbstractBaseUser, PermissionsMixin):

    '''
    This is the username field which I've removed ...
    username = models.CharField(
        _('username'),
        max_length=30,
        primary_key=True,
        help_text=_('Required. 30 characters or fewer. Letters, digits and @/./+/-/_ only.'),
        validators=[
            RegexValidator(
                r'^[\w.ñ@+-]+$',
                _('Enter a valid username. This value may contain only '
                  'letters, numbers ' 'and @/./+/-/_ characters.')
            ),
        ],
        error_messages={
            'unique': _("A user with that username already exists."),
        },
    )
    '''

    email = models.EmailField(max_length=254, primary_key=True)
    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['email']
    objects = UserManager()

UserManager类是：

class UserManager(BaseUserManager):
    use_in_migrations = True

    def _create_user(self, email, password, **extra_fields):
        """
        Creates and saves a User with the given email and password.
        """
        if not email:
            raise ValueError('The given email must be set')
        email = self.normalize_email(email)
        user = self.model(email=email, **extra_fields)
        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_user(self, email, password=None, **extra_fields):
        extra_fields.setdefault('is_superuser', False)
        return self._create_user(email, password, **extra_fields)

    def create_superuser(self, email, password, **extra_fields):
        extra_fields.setdefault('is_superuser', True)

        if extra_fields.get('is_superuser') is not True:
            raise ValueError('Superuser must have is_superuser=True.')

        return self._create_user(email, password, **extra_fields)

就像我最近删除了username字段一样，当我执行makemigrations进程时，我收到此错误：

 File "/home/bgarcial/workspace/fuupbol_project/userprofiles/forms.py", line 26, in <module>
    class CustomUserCreationForm(UserCreationForm):
  File "/home/bgarcial/.virtualenvs/fuupbol2/lib/python3.5/site-packages/django/forms/models.py", line 257, in __new__
    raise FieldError(message)
django.core.exceptions.FieldError: Unknown field(s) (username) specified for User

在我的forms.py中发生的事情是我使用UserCreationForm类继承她，在我的CustomUserCreationForm类

中的管理员中创建用户

class CustomUserCreationForm（UserCreationForm）： class Meta（UserCreationForm.Meta）： model =用户

在我的admin.py

中

class CustomUserAdmin(UserAdmin,):
    form = CustomUserChangeForm
    # Here I call the CustomUserCreationForm which inherit from
    # UserCreationForm
    add_form = CustomUserCreationForm
    fieldsets = UserAdmin.fieldsets + (
        (
            None, {
                'fields':(
                  ...  some fields  ...
                )
            }
        ),
    )

在这个admin.py文件中，我调用继承自的CustomUserCreationForm UserCreationForm django预先构建的课程

当我转到UserCreationForm class Meta source files时，username属性中的fields字段和{{{ 1}}属性

出于这个原因，field_classes字段在我的自定义用户模型架构中是否持久存在，真的吗？

如何在不考虑此详细信息的情况下删除用户名，或按照username课程及其含义进行操作...？

有一个更好的替代方法可以完成删除UserCreateForm模型中的username字段吗？

删除用户名字段到Django AbstractBaseUser自定义模型 - 为User指定的未知字段（用户名）
