mysql_exceptions.OperationalError: (1050, "Table 'api' already exists")

因为这些表已经存在了,需要通过migrate --fake-initial 告诉Django已经存在

初始化已存在的表 migrate --fake-initial

# 指定Django的setting配置文件执行migrate 
 python3 manage.py migrate --fake-initial --settings=FasterRunner.settings.pro

将会更新django_migrations表

"Unknown column 'django_content_type.name' in 'field list

因为django_content_type表

需要django_content_type是空的
需要加上项目的app_label和model

1054, "Unknown column 'django_content_type.name' in 'field list'"

  File "/usr/local/lib/python3.6/dist-packages/MySQLdb/connections.py", line 276, in query
    _mysql.connection.query(self, query)
django.db.utils.OperationalError: (1054, "Unknown column 'django_content_type.name' in 'field list'")

这是django_content_type中缺少新增加的表,补上就好

fake告诉Django已经在的表字段

# python3 manage.py migrate --settings=FasterRunner.settings.pro fastrunner --fake
Operations to perform:
  Apply all migrations: fastrunner
Running migrations:
  No migrations to apply.

最后执行新增加的表字段

# python3 manage.py migrate --settings=FasterRunner.settings.pro fastrunner
Operations to perform:
  Apply all migrations: fastrunner
Running migrations:
  Applying fastrunner.0012_auto_20200107_1126... OK
