使用复合主键生成控制器

Question

I have many tables with a composite primary key in my database. When i generate a controller from my models, i always get methods that only have one parameter. For example:

public ActionResult Edit(string id = null)
{
    ...
}

But what i want to achieve is to get the generated methods in my Controllers with all parameters for the primary key, something like this:

public ActionResult Edit(string pk1 = null, string pk2 = null, ...)
{
    ...
}

At the moment i have to change every single controller.
Is it possible to generate this type of controller in some way?

The scaffolding template (T4) are located at [Visual Studio Directory]\\Common7\\IDE\\ItemTemplates\\CSharp\\Web\\[MVC Version]\\CodeTemplates\\AddController . You can modify or copy these templates and import them in your project and make the appropriate modifications or you can also create brand new ones. Here is valuable tutorial on how to achieve this

Using Key attribute when you define your model

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Web;

namespace demomvc.Models
{
    public class MultipleKeyModel
    {
        [Key]
        public int Key1 { get; set; }
        [Key]
        public int Key2 { get; set; }
        [Key]
        public int Key3 { get; set; }
        public string Foo { get; set; }
    }
}
