是否可以仅为模型的一部分生成迁移？ [英] Is it possible to generate migration only for a part of model?

问题描述

我想使用自定义VSIX插件生成迁移，仅用于模型的一部分。我发现我可以通过overridnig方法Generate（IEnumerable operations，string @namespace，
string className）过滤从CSharpMigrationCodeGenerator继承的类中生成的代码。我在此方法中过滤了一个表的操作。我读到在修改迁移时我应该在PackageManager控制台中第二次调用Add-Migration。我做的。然后更新数据库。当我为整个
模型创建下一次迁移时，没有生成过滤表的代码，我必须自己为以前过滤的表编写代码。

我认为在迁移文件中进行更改时第二次调用Add-Migration方法将查看迁移代码并为我应用此迁移时出现的模型制作哈希值。

嗨Pavel，

欢迎来到MSDN论坛。

我试图涉及到高级专家进入你的线程。请等待回复。任何不便敬请谅解。

美好的一天。

I would like to generate migrations using custom VSIX plugin and only for a part of model. I found out I can filter generated code in class inherited from CSharpMigrationCodeGenerator by overridnig method Generate(IEnumerable operations, string @namespace, string className). I filtered operations for one table in this method. I read that I should invoke Add-Migration for second time in PackageManager console when modifying the migration. I did it. Then updated database. When I created next migration for whole model, code for filtered table was not generated and I had to write code for previously filtered table by myself.

I thought that invoking Add-Migration method for second time when I made changes in migration file will look into migration code and make hash for model which will arise when I apply this migration.
