django - 如何使 django 用户管理中的电子邮件字段成为必需

Question

我想让用户管理员中所需的电子邮件字段添加和
更改页面。我读了这篇文章:Django User model email field: how to make it mandatory我这样做了:

class MyUserCreationForm(UserCreationForm):
    def __init__(self, *args, **kwargs):
        super(MyUserCreationForm, self).__init__(*args, **kwargs)
        # make user email field required
        self.fields['email'].required = True

class UserAdmin(BaseUserAdmin):
    form = MyUserCreationForm
    add_form = MyUserCreationForm
    add_fieldsets = ((None, {'fields': ('username', 'email',
'password1', 'password2'), 'classes': ('wide',)}),)

admin.site.unregister(User)
admin.site.register(User, UserAdmin)

这在添加用户中工作正常，但在更改用户中我得到用户的
密码字段中显示的加密密码，而不是您的密码
通常见:

algorithm: pbkdf2_sha256 iterations: 24000 salt: ****** hash:
**************************************
Raw passwords are not stored, so there is no way to see this user's
password, but you can change the password using this form.

当我尝试从更改屏幕保存时，它说“请更正
下面的错误。”即使没有显示错误。

如何在更改表单中解决这些问题？

Answer 1

看看 source code of the UserAdmin .

UserAdmin 使用 UserChangeForm照原样 form属性(property)和UserCreationForm照原样 add_form属性(property)。但是您已经使用派生自 UserCreationForm 的类覆盖了它们。这对创建 View 没问题，但不适用于更新 View 。

from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.forms import UserCreationForm, UserChangeForm
from django.contrib.auth.models import User

class EmailRequiredMixin(object):
    def __init__(self, *args, **kwargs):
        super(EmailRequiredMixin, self).__init__(*args, **kwargs)
        # make user email field required
        self.fields['email'].required = True


class MyUserCreationForm(EmailRequiredMixin, UserCreationForm):
    pass


class MyUserChangeForm(EmailRequiredMixin, UserChangeForm):
    pass


class EmailRequiredUserAdmin(UserAdmin):
    form = MyUserChangeForm
    add_form = MyUserCreationForm
    add_fieldsets = ((None, {
        'fields': ('username', 'email', 'password1', 'password2'), 
        'classes': ('wide',)
    }),)

admin.site.unregister(User)
admin.site.register(User, EmailRequiredUserAdmin)

这应该可以解决问题。
