  • django有InvalidMigrationPlan("Migration plans with both forwards and backwards migrations ""are not supported. Please split your migration process into ""separate plans of only forwards OR backwards migrations.",plan,)报错是怎么回事

    报错的原因错误在Django中是由于迁移计划中同时存在"forwards"和"backwards"迁移而产生的。假设现在你有一个迁移文件，叫做它包含了"forwards"和"backwards"操作，你可以这样操作：删除迁移文件中的"backwards"操作创建一个新的迁移文件并在里面添加"backwards"操作这是的例子这是的例子在这个例子中，我们将"forwards"操作放在了文件中，将"backwards"操作放在了文件中。总之，在Django中使用迁移时，如果出现错误，您需要将"forwards"和"backwards"操作分成单独的迁移文件来解决。
