模型类和映射 [英] Model class and Mapping

问题描述

我定义了Client类。我也有Mapping\ClientMap.cs文件，该文件使用Fluent API定义列名。但是，我不确定如何调用它，因为我没有看到ClientMap.cs代码正在执行。

I have the Client class defined. I also have Mapping\ClientMap.cs file that defines column names using Fluent API. However, I am not sure how to "invoke" it as I don't see the ClientMap.cs code being executed.

我也有这个：

namespace CardNumbers.Data
{
    public class Repository : DbContext, IRepository
    {
        public DbSet<Client> Clients { get; set; }
        public DbSet<ClientOrder> ClientOrders { get; set; }
        public DbSet<Reorder> Reorders { get; set; }
        public DbSet<Operator> Operators { get; set; }

我知道这不是一个很好的做法，但这就是我们使用

which I know is not a very good practice, but that's how we were building the application with the instructor.

所以，我的问题是-我需要添加什么以确保在运行时调用Fluent API代码？

So, my question is - what do I need to add to make sure the Fluent API code is invoked in run-time?

谢谢。

推荐答案

流利的映射应该添加到您的 存储库这样的类

The fluent mapping should be added at the bottom of your "Repository" class like this

protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        //add fluent api code
    }

原因我引用您的存储库是，您实际上并没有在其中实现存储库模式。您确实应该将此定义为特定的DbContext，然后拥有一个可以容纳多个上下文的存储库。请参阅有关实现存储库的写得很好的文章： http://www.asp.net/mvc/tutorials/getting-started-with-ef-using- mvc /在一个asp-net-mvc应用程序中实现存储库和单元工作模式

The reason I am quoting your Repository is that you are not really implementing a repository pattern there. You should really have this defined as a specific DbContext, and then have a repository which can take multiple contexts. See this very well written post about implementing a repository: http://www.asp.net/mvc/tutorials/getting-started-with-ef-using-mvc/implementing-the-repository-and-unit-of-work-patterns-in-an-asp-net-mvc-application
