如何从MVC.net中的MongoDB传递ObjectId [英] How to pass ObjectId from MongoDB in MVC.net

问题描述

我正在与Mongo，NoRM和MVC .Net开始一个新项目.

I'm starting a new project with Mongo, NoRM and MVC .Net.

在我使用FluentNHibernate之前，我的ID是整数，现在我的ID是ObjectId.因此，当我具有编辑"链接时，我的URL如下所示:

Before I was using FluentNHibernate so my IDs were integer, now my IDs are ObjectId. So when I have an Edit link my URL looks like this :

WebSite/Admin/Edit/23,111,160,3,240,200,191,56,25,0,0,0

WebSite/Admin/Edit/23,111,160,3,240,200,191,56,25,0,0,0

并且它不会作为ObjectId自动绑定到我的控制器

And it does not bind automaticly to my controller as an ObjectId

您对此有什么建议/最佳实践吗?我是否需要每次都对ID进行编码/解码?

Do you have any suggestions/best practices to work with this? Do I need to encode/decode the ID everytime?

谢谢！

推荐答案

我使用以下

public class ObjectIdModelBinder : DefaultModelBinder
{
    public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        string value = controllerContext.RouteData.Values[bindingContext.ModelName] as string;
        if (String.IsNullOrEmpty(value)) {
            return ObjectId.Empty;
        }
        return new ObjectId(value);
    }
}

和

protected void Application_Start()
    {
        ......

        ModelBinders.Binders.Add(typeof(ObjectId), new ObjectIdModelBinder()); 
    }

几乎忘记了，从ObjectId.ToString()
