Question

我已根据本教程成功为User模型创建了自己的扩展程序：

https://docs.djangoproject.com/en/dev/topics/auth/customizing/#custom-users-and-permissions

我还需要将ForeignKey添加到Company模型，以便将每个用户分配给公司。但这根本没有显示在管理员中，无论是在初始管理视图还是编辑视图中。

我在MyUser类中添加了ForeignKey引用，如下所示：

class MyUser(AbstractBaseUser):
    email = models.EmailField(
        verbose_name='email address',
        max_length=255,
        unique=True,
    )

    date_of_birth = models.DateField()
    company = models.ForeignKey('Company', on_delete=models.CASCADE, default=1)
    is_active = models.BooleanField(default=True)
    is_admin = models.BooleanField(default=False)

    objects = MyUserManager()

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['date_of_birth']

...

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 myapp.models import Company, Camera, MyUser

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)

    class Meta:
        model = MyUser
        fields = ('email', 'date_of_birth', 'company')

    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().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 = MyUser
        fields = ('email', 'password', 'date_of_birth', 'company', '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', 'date_of_birth', 'company', 'is_admin')
    list_filter = ('is_admin',)
    fieldsets = (
        (None, {'fields': ('email', 'password')}),
        ('Personal info', {'fields': ('date_of_birth',)}),
        ('Company info', {'fields': ('company',)}),
        ('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', 'date_of_birth', 'password1', 'password2')}
        ),
    )
    search_fields = ('email',)
    ordering = ('email',)
    filter_horizontal = ()

admin.site.register(MyUser, UserAdmin)
admin.site.register(Company)
admin.site.register(Camera)

admin.site.unregister(Group)

如果将外键添加到自定义用户模型，则只需在fieldsets属性上指定它即可。

例如，在models.py中使用此自定义用户：

class CustomUser(AbstractUser):
    company = models.ForeignKey('Company', on_delete=models.CASCADE)

您需要在admin.py中使用此功能：

from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.forms import UserChangeForm
from myapp.models import CustomUser

class MyUserChangeForm(UserChangeForm):
    class Meta(UserChangeForm.Meta):
        model = CustomUser

class MyUserAdmin(UserAdmin):
    form = MyUserChangeForm

    fieldsets = UserAdmin.fieldsets + (
        (None, {'fields': ('company')}),
    )


admin.site.register(CustomUser, MyUserAdmin)

现在您可以在管理员中选择用户的公司。

Django自定义用户模型ForeignKey添加不显示在管理员中
