实体代码首先迁移和删除数据库

Question

We're using EF Code First and migrations for a project. We're commiting our migrations to source, and everything is great. However, if someone delete's their database, or we get a new person on the project, the database will throw errors because it's trying to run the migrations. Is there a way to make it so that if the database doesn't exist, it ignores migrations? I can't seem to find anything about this.

Answer 1

I would look at how you are using DbMigrationsConfiguration from the Entity framework. You might need something like this in your global asx file:

    Database.SetInitializer(new MigrateDatabaseToLatestVersion<YourContext, YourConfiguration>());

Then in your configuration file for migrations you may need something like this:

    internal sealed class YourConfiguration : DbMigrationsConfiguration<YourContext>
{
    public Configuration()
    {
        AutomaticMigrationsEnabled = true;
    }...

Without more info and code examples, I can only point you in the right direction.
