我们正在使用人工迁移的EF代码第一。 问题在于我们需要在两个项目之间共享一个数据库。
Project-A
---DbContext-A
---------Model1
---------Model2
---------Model3
Project-B
---DbContext-A
---------Model2
---------Model3
---------Model4
有些迁移档案是相同的,但有些档案是不同的。例如:项目B需要模型4,但项目A没有。
目前,如果我用一种迁移方式更新数据库,DbContext将无法在其他项目中工作。
处理这种情况的最佳方式是什么?
我的感觉是,这与移民的意图背道而驰。我认为,你应该打破 < code> DbContext 、实体和向两个项目共享的单独集会的迁移。
如果不是此选项, 您必须禁用与模型的兼容性检查。 兼容性检查是作为 < code> IDBIntializer. IntializeDatabase 执行的一部分完成的, 该执行负责调用 < code> Database. 兼容与 Model 兼容, 所以写您自定义的 DB 初始化器不会让你超过该步。 这也意味着您将接管确保数据库与模型兼容的责任。 EF 帮不了你更多忙 。
