entity-framework - EF 5 Code First 添加带有种子的新表

Question

我有我想要的数据库设置，只是对现有表进行调整并偶尔添加新表，并且在初始播种后已将实时数据添加到表中。因此，如果我想添加一个新表并只为该表提供种子，同时将其他表中的数据保持原样，这可能吗？我不想删除现有表或丢失现有数据，我只想添加一个新表并在创建它的同时用数据播种它。

I'd love to know if there's a better way of doing this.

When I add a model, then in my Migrations/Congiruation.cs file I add the appropriate seeding values and basically just comment out the rest. ie:

var Locations = new List<Location>
{
    new Location { Suburb="Sydney", Postcode = "2000", State = "NSW"}
};

Locations.ForEach(s => context.Locations.Add(s));
context.SaveChanges();

for a new Location model. Unless you have set drop database if model changes in your initialiser, then running update-database in your package manager console will not affect any of your other tables or data.
