为什么站点匹配查询不存在？

Question

我在做jwt认证。我正在使用django rest auth包中的一些代码进行注册，注册端点和管理区域都有这个问题。我知道很多人在我面前问过这个问题，但我不知道为什么这个解决方案在我的情况下不起作用。你知道吗

我在贝壳里试过这个：

>>> from django.contrib.sites.models import Site
>>> site = Site()
>>> site.domain = 'answerly.com'
>>> site.name = 'answerly.com'
>>> site.save()

我的设置：

...
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    # local apps
    'pages',
    'accounts',
    # third party packages
    'rest_framework',
    'rest_framework.authtoken',
    'rest_auth',
    'django.contrib.sites',
    'allauth',
    'allauth.account',
    'rest_auth.registration',
]
...
REST_USE_JWT = True
...

网址：

from django.contrib import admin
from django.urls import path, include
from rest_auth.registration.views import RegisterView
# from rest_auth.views import LoginView, LogoutView


urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('pages.api.urls')),
    path('accounts/registration/', RegisterView.as_view(), name='register'), 
    # path('rest-auth/registration/', include('rest_auth.registration.urls'))  
]

我有一个共同的解决方案：

Traceback (most recent call last):
File "/home/valentyn/Dev/Answerly/venv/lib/python3.6/site-packages/django
/db/backends/utils.py", line 84, in _execute
    return self.cursor.execute(sql, params)
  File "/home/valentyn/Dev/Answerly/venv/lib/python3.6/site-packages/django/db/backends/sqlite3/base.py", line 383, in execute
    return Database.Cursor.execute(self, query, params)
sqlite3.IntegrityError: UNIQUE constraint failed: django_site.domain

上述异常是以下异常的直接原因：

我正试图更好地理解正在发生的事情，所以请容忍我，因为我有几个问题：

1. 你移植了“python”吗管理.py迁移“添加后”rest_框架.authtoken“，”到您安装的应用程序？参考：https://django-rest-auth.readthedocs.io/en/latest/installation.html#

2. 你是否在你的网站中添加了“SITE\u ID=1”设置.py？请参阅：https://django-rest-auth.readthedocs.io/en/latest/installation.html#registration-optional
