User Model

Django default user model is not good. So create a custom model for new projects.

 

• 自定义 User Model

class User(AbstractBaseUser, PermissionsMixin):
    """User in the system."""
    email     = models.EmailField(max_length=255, unique=True)
    name      = models.CharField(max_length=255)
    is_active = models.BooleanField(default=True)
    is_staff  = models.BooleanField(default=False)

    objects = UserManager()　　# ----> 

    USERNAME_FIELD = 'email'

class UserManager(BaseUserManager):
    """Manager for users."""

    def create_user(self, email, password=None, **extra_fields):
        """Create, save and return a new user."""
        if not email:
            raise ValueError('User must have an email address.')
        user = self.model(email=self.normalize_email(email), **extra_fields)
        user.set_password(password)
        user.save(using=self._db)

        return user

    def create_superuser(self, email, password):
        """Create and return a new superuser."""
        user = self.create_user(email, password)
        user.is_staff = True　　　　# --> more
        user.is_superuser = True　 # --> more
        user.save(using=self._db)

        return user

 添加超级用户，可见，这里改为了 login by email, but not username as default.

$ docker-compose run --rm app sh -c "python manage.py createsuperuser"
Starting c2-app-api-2_db_1 ... done
Email: hao123
Password:
Password (again):
Superuser created successfully. 

 settings.py

AUTH_USER_MODEL = 'core.User'

 

• 定制 Django Admin

在此之前，可以先从 test 入手。

class AdminSiteTests(TestCase):
    """Tests for Django admin."""

    def setUp(self):
        """Create user and client."""
        self.client = Client()
        self.admin_user = get_user_model().objects.create_superuser(
            email='admin@example.com',
            password='testpass123',
        )
        self.client.force_login(self.admin_user)
        self.user = get_user_model().objects.create_user(
            email='user@example.com',
            password='testpass123',
            name='Test User'
        )

    def test_users_lists(self):
        """Test that users are listed on page."""
        url = reverse('admin:core_user_changelist')
        res = self.client.get(url)

        self.assertContains(res, self.user.name)
        self.assertContains(res, self.user.email)

    def test_edit_user_page(self):
        """Test the edit user page works."""
        url = reverse('admin:core_user_change', args=[self.user.id])
        res = self.client.get(url)

        self.assertEqual(res.status_code, 200)

    def test_create_user_page(self):
        """Test the create user page works."""
        url = reverse('admin:core_user_add')
        res = self.client.get(url)

        self.assertEqual(res.status_code, 200)

这里是 admin.py。

class UserAdmin(BaseUserAdmin):
    """Define the admin pages for users."""
    ordering = ['id']
    list_display = ['email', 'name']
    fieldsets = (
        (None, {'fields': ('email', 'password')}),
        (
            _('Personal Info'), 
            {
                'fields': (
                     'name',
                 )
            }
        ),
        (
            _('Permissions'),
            {
                'fields': (
                    'is_active',
                    'is_staff',
                    'is_superuser',
                )
            }
        ),
        (_('Important dates'), {'fields': ('last_login',)}),　　# <---- default item
    )
    readonly_fields = ['last_login']
    add_fieldsets = (
        (None, {
            'classes': ('wide',),　　# --> css
            'fields': (
                'email',
                'password1',
                'password2',
                'name',
                'is_active',
                'is_staff',
                'is_superuser',
            ),
        }),
    )

According to Django Documentation : "Two useful classes defined by the default admin site stylesheet are collapse and wide. Fieldsets with the collapse style will be initially collapsed in the admin and replaced with a small “click to expand” link. Fieldsets with the wide style will be given extra horizontal space."

Try to replace extrapetty by collapse on your example and see what's happen.
