mysql - 1146 "app_name.django_site missing"

Question

我正在使用 Django 1.11 制作应用程序“cnfs”，并使用 MYSQL 数据库。我经常遇到这个问题，当我输入以下代码时，我收到这样的错误:

$python manage.py migrate

System check identified some issues: WARNINGS: ?: (mysql.W002) MySQL Strict Mode is not set for database connection 'default' HINT: MySQL's Strict Mode fixes many data integrity problems in MySQL, such as data truncation upon insertion, by escalating warnings into errors. It is strongly recommended you activate it. See: https://docs.djangoproject.com/en/1.11/ref/databases/#mysql-sql-mode Operations to perform: Apply all migrations: admin, auth, cnfs, contenttypes, sites Running migrations: No migrations to apply. Traceback (most recent call last): File "manage.py", line 22, in execute_from_command_line(sys.argv) File "/home/ubuntu/.local/lib/python2.7/site-packages/django/core/management/init.py", line 363, in execute_from_command_line utility.execute() File "/home/ubuntu/.local/lib/python2.7/site-packages/django/core/management/init.py", line 355, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/home/ubuntu/.local/lib/python2.7/site-packages/django/core/management/base.py", line 283, in run_from_argv self.execute(*args, **cmd_options) File "/home/ubuntu/.local/lib/python2.7/site-packages/django/core/management/base.py", line 330, in execute output = self.handle(*args, **options) File "/home/ubuntu/.local/lib/python2.7/site-packages/django/core/management/commands/migrate.py", line 227, in handle self.verbosity, self.interactive, connection.alias, apps=post_migrate_apps, plan=plan, File "/home/ubuntu/.local/lib/python2.7/site-packages/django/core/management/sql.py", line 53, in emit_post_migrate_signal **kwargs File "/home/ubuntu/.local/lib/python2.7/site-packages/django/dispatch/dispatcher.py", line 193, in send for receiver in self._live_receivers(sender) File "/home/ubuntu/.local/lib/python2.7/site-packages/django/contrib/sites/management.py", line 20, in create_default_site if not Site.objects.using(using).exists(): File "/home/ubuntu/.local/lib/python2.7/site-packages/django/db/models/query.py", line 670, in exists return self.query.has_results(using=self.db) File "/home/ubuntu/.local/lib/python2.7/site-packages/django/db/models/sql/query.py", line 517, in has_results return compiler.has_results() File "/home/ubuntu/.local/lib/python2.7/site-packages/django/db/models/sql/compiler.py", line 845, in has_results return bool(self.execute_sql(SINGLE)) File "/home/ubuntu/.local/lib/python2.7/site-packages/django/db/models/sql/compiler.py", line 886, in execute_sql raise original_exception django.db.utils.ProgrammingError: (1146, "Table 'cnfs.django_site' doesn't exist")

我确实花了几天时间在这上面，当我使用默认的 django 数据库引擎 sqlite3 时，我没有遇到这个问题。我尝试这样做: $python manage.py 迁移站点

我的 SITE_ID 设置已设为 1。我尝试从 INSTALLED_APPS 设置中删除“django.contrib.sites”，但这会引发此错误:

Internal Server Error: / Traceback (most recent call last): File "/home/ubuntu/.local/lib/python2.7/site-packages/django/core/handlers/exception.py", line 41, in inner response = get_response(request) File "/home/ubuntu/.local/lib/python2.7/site-packages/django/utils/deprecation.py", line 138, in call response = self.process_request(request) File "/home/ubuntu/.local/lib/python2.7/site-packages/subdomains/middleware.py", line 62, in process_request super(SubdomainURLRoutingMiddleware, self).process_request(request) File "/home/ubuntu/.local/lib/python2.7/site-packages/subdomains/middleware.py", line 38, in process_request (self.get_domain_for_request(request), request.get_host())) File "/home/ubuntu/.local/lib/python2.7/site-packages/subdomains/middleware.py", line 31, in get_domain_for_request return get_domain() File "/home/ubuntu/.local/lib/python2.7/site-packages/subdomains/utils.py", line 12, in current_site_domain from django.contrib.sites.models import Site File "/home/ubuntu/.local/lib/python2.7/site-packages/django/contrib/sites/models.py", line 84, in class Site(models.Model): File "/home/ubuntu/.local/lib/python2.7/site-packages/django/db/models/base.py", line 118, in new "INSTALLED_APPS." % (module, name) RuntimeError: Model class django.contrib.sites.models.Site doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

如有任何建议，我们将不胜感激。

谢谢。

Answer 1

从已安装的应用程序中取消注释 django.contrib.sites

然后

python manage.py migrate sites
python manage.py migrate

如果数据库中的表很少，请删除这些表，然后运行此
