python - 通过管理员创建新用户时出现 NoReverseMatch 错误

Question

在我的 Django 应用程序中，我创建了一个扩展 AbstractUser 的自定义用户模型。我更新了 AUTH_USER_MODEL 并像这样在管理员下注册了它

admin.site.register(MyUser, UserAdmin)

我运行了迁移，然后进入我的管理页面，看到它列在应用程序的模型下。但是当我尝试从该页面创建一个新用户时，它给了我这个错误。

models.py 中的用户类:

class MyUser(AbstractUser):
    id = models.CharField(primary_key = True, unique = True, max_length = 50)

有什么想法吗？ 编辑:更新为包含主 urls.py

from django.conf.urls import url, include
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^api/', include('api.urls'))
]

您已将主键替换为 CharField，但您仍在使用 Django 的 UserAdmin ModelAdmin。 Django 的 UserAdmin 不要求提供 ID——它默认为空字符串。 (您可以通过检查来自 NoReverseMatch 异常的参数中的空字符串来验证这一点。)

您需要创建一个允许您指定 ID 的 ModelAdmin，这样它就不会以空字符串结束。以下 admin.py 将允许您指定 ID，从而摆脱 NoReverseMatch 异常。

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin

from .models import MyUser

class MyUserAdmin(UserAdmin):
    add_fieldsets = (
        (None, {
            'fields': ('id', 'username', 'password1', 'password2'),
        }),
    )

# Register your models here.
admin.site.register(MyUser, MyUserAdmin)
