Django:扩展用户模型;只能添加管理员用户

我正在尝试按照

扩展Django的用户模型

https://docs.djangoproject.com/en/1.9/topics/auth/customizing/

现在我可以添加一个我希望与每个用户关联的新字段。但问题是,我无法添加非管理员用户。如果我添加一个用户并且不使它们成为管理员,则登录失败

但如果我以任何管理员用户身份登录,我清楚地看到

为什么我的应用程序只允许管理员登录?我是否必须为非管理员用户创建单独的登录屏幕?

这是我的models.py

from django.db import models
from django.contrib.auth.models import (
    User, BaseUserManager, AbstractBaseUser
)
'''
class UserProfile(models.Model):
    appcodes = models.TextField()
    user = models.ForeignKey(User, unique=True)
'''    
class AppCodeUserManager(BaseUserManager):
    def create_user(self, email, appcode, password=None):
        """
        Creates and saves a User with the given email, appcode and password.
        """
        if not email:
            raise ValueError('Users must have an email address')

        user = self.model(
            email=self.normalize_email(email),
            appcodes=appcode
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, email, appcode, password):
        """
        Creates and saves a superuser with the given email, appcode and password.
        """
        print("Creating superuser...")
        user = self.create_user(email,
            password=password,
            appcodes=appcode
        )
        user.is_admin = True
        user.save(using=self._db)
        return user

class AppCode(models.Model):

    appcode_name = models.CharField(max_length=255,unique=True)

class AppCodeUser(AbstractBaseUser):
    email = models.EmailField(
        verbose_name='email address',
        max_length=255,
        unique=True,
    )
    appcodes = models.TextField()#CharField(max_length=255,unique=True,default="RIK0")#models.ManyToManyField(AppCode)
    is_active = models.BooleanField(default=True)
    is_admin = models.BooleanField(default=False)

    objects = AppCodeUserManager()

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['appcodes']

    def get_appcodes(self):

        return ", ".join([p.appcode_name for p in self.appcodes.all()])
    get_appcodes.short_description = 'Appcodes'
    get_appcodes.allow_tags = True

    def get_full_name(self):
        # The user is identified by their email address
        return self.email

    def get_short_name(self):
        # The user is identified by their email address
        return self.email

    def __str__(self):              # __unicode__ on Python 2
        return self.email

    def has_perm(self, perm, obj=None):
        "Does the user have a specific permission?"
        # Simplest possible answer: Yes, always
        return True

    def has_module_perms(self, app_label):
        "Does the user have permissions to view the app `app_label`?"
        # Simplest possible answer: Yes, always
        return True

    @property
    def is_staff(self):
        "Is the user a member of staff?"
        # Simplest possible answer: All admins are staff
        return self.is_admin

我想要做的就是为每个用户添加TextField()。该字段将命名为appcodes

这是我的admin.py

from django import forms
from django.contrib import admin
from django.contrib.auth.models import Group
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin
from django.contrib.auth.forms import ReadOnlyPasswordHashField

from .models import AppCodeUser


class UserCreationForm(forms.ModelForm):
    """A form for creating new users. Includes all the required
    fields, plus a repeated password."""

    password1 = forms.CharField(label='Password', widget=forms.PasswordInput)
    password2 = forms.CharField(label='Password confirmation', widget=forms.PasswordInput)
    appcodes=forms.TextInput
    class Meta:
        model = AppCodeUser
        fields = ('email', 'appcodes')

    def clean_password2(self):
        # Check that the two password entries match
        password1 = self.cleaned_data.get("password1")
        password2 = self.cleaned_data.get("password2")
        if password1 and password2 and password1 != password2:
            raise forms.ValidationError("Passwords don't match")
        return password2

    def save(self, commit=True):
        # Save the provided password in hashed format
        user = super(UserCreationForm, self).save(commit=False)
        user.set_password(self.cleaned_data["password1"])
        if commit:
            user.save()
        return user


class UserChangeForm(forms.ModelForm):
    """A form for updating users. Includes all the fields on
    the user, but replaces the password field with admin's
    password hash display field.
    """
    password = ReadOnlyPasswordHashField()

    class Meta:
        model = AppCodeUser
        fields = ('email', 'password', 'appcodes', 'is_active', 'is_admin')

    def clean_password(self):
        # Regardless of what the user provides, return the initial value.
        # This is done here, rather than on the field, because the
        # field does not have access to the initial value
        return self.initial["password"]

class UserAdmin(BaseUserAdmin):
    # The forms to add and change user instances
    form = UserChangeForm
    add_form = UserCreationForm

    # The fields to be used in displaying the User model.
    # These override the definitions on the base UserAdmin
    # that reference specific fields on auth.User.
    list_display = ('email','appcodes','is_admin','is_active')
    list_filter = ('is_admin',)
    fieldsets = (
        (None, {'fields': ('email', 'password')}),
        ('Appcode info', {'fields': ('appcodes',)}),
        ('Permissions', {'fields': ('is_admin',)}),
    )
    # add_fieldsets is not a standard ModelAdmin attribute. UserAdmin
    # overrides get_fieldsets to use this attribute when creating a user.
    add_fieldsets = (
        (None, {
            'classes': ('wide',),
            'fields': ('email', 'appcodes', 'password1', 'password2')}
        ),
    )
    search_fields = ('email',)
    ordering = ('email',)
    filter_horizontal = ()

# Now register the new UserAdmin...
admin.site.register(AppCodeUser, UserAdmin)
# ... and, since we're not using Django's built-in permissions,
# unregister the Group model from admin.
admin.site.unregister(Group)

在我的settings.py我有

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'hdfsStats.apps.HdfsstatsConfig',
]

MIDDLEWARE_CLASSES = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
AUTH_USER_MODEL = 'hdfsStats.AppCodeUser'

休息是我猜的默认值
