我正在使用Django 2.0
我扩展了AbstractBaseUser模型来创建自定义用户模型。
在我的accounts / models.py中
class UserManager(BaseUserManager):
def create_user(self, email, password=None, is_staff=False, is_admin=False, is_active=False):
if not email:
raise ValueError('User must have an email address')
if not password:
raise ValueError('User must have a password')
user = self.model(
email=self.normalize_email(email)
)
user.is_staff = is_staff
user.is_admin = is_admin
user.is_active = is_active
user.set_password(password)
user.save(using=self._db)
return user
def create_staffuser(self, email, password=None):
return self.create_user(
email,
password=password,
is_staff=True,
is_active=True
)
def create_superuser(self, email, password=None):
return self.create_user(
email,
password=password,
is_staff=True,
is_admin=True,
is_active=True
)
class User(AbstractBaseUser):
id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
email = models.EmailField(max_length=250, blank=False, unique=True)
first_name = models.CharField(max_length=150, blank=True)
last_name = models.CharField(max_length=150, blank=True)
is_staff = models.BooleanField(default=False)
is_active = models.BooleanField(default=False)
is_admin = models.BooleanField(default=False)
groups = models.ManyToManyField(Group, blank=True)
last_login = models.DateTimeField(auto_now=True)
date_joined = models.DateTimeField(auto_now_add=True)
USERNAME_FIELD = 'email'
objects = UserManager()
@property
def is_staff(self):
return self.is_staff
@property
def is_active(self):
return self.is_active
@property
def is_superuser(self):
return self.is_admin
def __str__(self):
if self.first_name is not None:
return self.get_full_name()
return self.email
def get_full_name(self):
if self.last_name is not None:
return self.first_name + ' ' + self.last_name
return self.get_short_name()
def get_short_name(self):
return self.first_name
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
并将此User模型用于管理员。我已将下面的代码添加到example中给出的accounts / admin.py中
from accounts.models import User
from django import forms
from django.contrib import admin
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin
from django.contrib.auth.forms import ReadOnlyPasswordHashField
from django.contrib.auth.models import Group
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 = User
fields = ('email', 'first_name', 'last_name')
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 = User
fields = ('email', 'password', 'first_name', 'last_name', 'is_active', 'is_admin', 'is_staff')
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', 'first_name', 'last_name', 'is_admin')
list_filter = ('is_admin',)
fieldsets = (
(None, {'fields': ('email', 'password')}),
('Personal info', {'fields': ('first_name', 'last_name',)}),
('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', 'first_name', 'last_name', 'password1', 'password2')}
),
)
search_fields = ('email', 'first_name', 'last_name',)
ordering = ('email', 'first_name', 'last_name',)
filter_horizontal = ()
# Now register the new UserAdmin...
admin.site.register(User, UserAdmin)
# ... and, since we're not using Django's built-in permissions,
# unregister the Group model from admin.
admin.site.unregister(Group)
但是当我跑步的时候
python manage.py makemigrations
它给出了错误
File "/Users/anuj/code/PyCharm/notepad/src/accounts/admin.py", line 37, in <module>
class UserChangeForm(forms.ModelForm):
raise FieldError(message)
django.core.exceptions.FieldError: Unknown field(s) (is_staff, is_active) specified for User
从is_staff删除is_active和UserChangeForm工作正常。我甚至将字段添加到模型中。
