如何在django用户admin中创建电子邮件字段

Question

我想在用户admin添加和更改页面中创建所需的电子邮件字段.我读过这篇文章:Django用户模型电子邮件字段:如何使其成为强制性的,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)

这在添加用户时工作正常,但在更改用户时,我得到密码字段中显示的用户加密密码,而不是您通常看到的:

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,它会显示"请更正以下错误".即使没有显示错误.

如何在更改表单中修复这些问题？

看看UserAdmin的源代码.

该UserAdmin使用UserChangeForm,因为它的form属性和UserCreationForm它的add_form属性.但是你已经使用派生的类覆盖了它们,UserCreationForm对于创建视图是可以的,但是对于更新视图不​​起作用.

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.
