当使用多个1:Many或Many:Many表时，存储库是什么样的?

问题描述

我有一个MVC应用程序，该应用程序直接在视图中使用该实体框架模型对象.我不确定这对设计模式有多严重，但是基于此示例我需要使用存储库来实现缓存.

I have a MVC application that uses that entity framework model object directly in the view. I'm not sure how bad of a design pattern this is, but based on this sample I need to use a repository to implement caching.

namespace MVCAzureStore.Services.Caching
{
    public class CachedProductsRepository : CachedDataSource, IProductRepository
    {
        private readonly IProductRepository repository;

        public CachedProductsRepository(IProductRepository repository, ObjectCache cacheProvider) :
            base(cacheProvider, "Products")
        {
            this.repository = repository;
        }

        public List<string> GetProducts()
        {
            return RetrieveCachedData(
                "allproducts",  () => this.repository.GetProducts(),
                new CacheItemPolicy { AbsoluteExpiration = DateTime.UtcNow.AddMinutes(1) });
        }
    }
}

由于此视图使用了EF的导航属性，因此我需要复制此概念(或在我的视图中有类似的东西).

Since this view uses the navigation properties of the EF I need to replicate this notion(or have something similar in mine).

问题

任何代码示例，文章或更多信息都将受到赞赏，因为我以这种方式学习得最好

Any code sample, article, or more info would be appreciated, since I learn best that way

推荐答案

请参阅本教程中的存储库，该存储库使您可以为指定的导航属性指定紧急加载: http://www.asp.net/entity-framework/tutorials/implementing-the-repository-and-unit-of-work-patterns-in-an-asp-net-mvc-application

See the repository in this tutorial, which allows you to specify eager loading for specified navigation properties:http://www.asp.net/entity-framework/tutorials/implementing-the-repository-and-unit-of-work-patterns-in-an-asp-net-mvc-application
