从修改数据库停止实体框架 [英] Stop Entity Framework from modifying database

问题描述

我开始玩的code-第一的方针，以实体框架，主要是让我可以在我看来，（否则装饰我的物业，注释显示，现在我要创建一个类这是几乎相同的实体框架生成对我来说，这样我可以添加注释，然后从一个对象中的数据复制到下）的人。

I'm starting to play around with the code-first approach to the entity framework, primarily so that I can decorate my properties with annotations for display in my view (otherwise, right now I have to create a class that is nearly identical to the one that entity framework generated for me just so I can add annotations, and then copy the data from one object to the next).

现在它看起来就像当我开始我的应用程序，它试图创建一个数据库。

Right now it looks like when I start my application it is trying to create a database.

我不希望实体框架为曾经修改我的数据库。不，不是永远。甚至不要尝试。这真的不是那么难修改数据库;我会觉得舒服多了，如果我这样做我自己。设计数据库时，我并不需要一个框架来握住我的手。

I do not want entity framework to ever modify my database. No. Not ever. Don't even try it. It really isn't that hard to modify databases; I would feel much more comfortable if I did that myself. I don't need a framework to hold my hand when designing a database.

我可以告诉框架停止试图修改我的数据库？我很犹豫，现在使用code-首先作为一个事实，即它试图改变我的数据库是相当可怕的。即使是在发展中，我再也不想看到它发生。

Can I tell the framework to stop trying to modify my database? I'm very hesitant to use code-first now as the fact that it's trying to modify my database is rather frightening. Even in development I never want to see it happen.

我是运气不好？

推荐答案

如果你不想EF创建数据库，可以禁用数据库初始化：

If you don't want EF to create your database, you can disable the database initializer:

public class SchoolDBContext: DbContext 
{
    public SchoolDBContext() : base("SchoolDBConnectionString")
    {            
        //Disable initializer
        Database.SetInitializer<SchoolDBContext>(null);
    }
    public DbSet<Student> Students { get; set; }
    public DbSet<Standard> Standards { get; set; }
}
