起源

在models中设置unique，多次migrate就会报下面的信息

raise errorclass, errorvalue django.db.utils.OperationalError: (1061, "Duplicate key name> 'web_privilege_name_102618e8_uniq'")

原因

Running migrations:(0.002) b'SHOW FULL TABLES'; args=NoneALTER TABLE `web_privilege` ADD CONSTRAINT `web_privilege_name_102618e8_uniq` UNIQUE (`name`); (params ())(0.001) None; args=()

解决方法

mysql> DROP INDEX [index_name] ON [table_name];即mysql> DROP INDEX web_privilege_name_102618e8_uniq ON web_privilege;
