django 扩展user字段

方式一:用自定义的user对象替换django中的默认

在model.py中自定义user对象
'''
自定义用户管理

class MyUserManager(BaseUserManager):

在admin.py中,修改表单样式

"""
自定义用户
"""
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)

    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', 'is_admin','device_id')
    list_filter = ('is_admin',)
    fieldsets = (

    ordering = ('email',)
    filter_horizontal = ()


# Now register the new UserAdmin...
admin.site.register(MyUser, UserAdmin)
# ... and, since we're not using Django's built-in permissions,
# unregister the Group model from admin.
#admin.site.unregister(Group)

在settings.py中定义

#使用自定义用户
#AUTH_USER_MODEL = 'jkx.MyUser'

方式二:新建一个新的模型,user作为外键导入

Model.py添加

#扩展user模型
class UserProfile(models.Model):
    user = models.OneToOneField(User)
    description = models.TextField(max_length=51200)
    scope = models.IntegerField(default=100)


def create_user_profile(sender, instance, created, **kwargs):
    if created:
        profile, created = UserProfile.objects.get_or_create(user=instance)


post_save.connect(create_user_profile, sender=User)

Views.py添加
#扩展user测试
def userDemo(request):
    desc = User.objects.all()[0].get_profile().description
    return HttpResponse(desc)

Utls.py中添加

#扩展user
url(r'^profile/',views.userDemo),

# 扩展user
class UserProfileAdmin(admin.ModelAdmin):
    fields = ('user', 'description',)


admin.site.register(UserProfile, UserProfileAdmin)

修改settings.py

#扩展user
AUTH_PROFILE_MODULE='jkx.UserProfile'
