修改文章是网站必不可少的内容，在我的文章里，文章列表后面操作栏有【修改】链接，点击调转到[UserEdit]Action，今天来实现这个Action。

还是打开【ArticleController】，添加[UserEdit(int id)]Action这里的id指文章Id。

/// 
        /// 修改文章        /// 
        /// 文章id        [UserAuthorize]        public ActionResult UserEdit(int id)        {            return View(articleRsy.Find(id));        }

右键添加强类型视图，视图与添加文章类似

@model Ninesky.Models.Article@{    ViewBag.Title = "修改文章";    Layout = "~/Views/Shared/_User.cshtml";}
     
    
      
        
       
            
        您现在的位置： 修改文章        
       
        
       
                    @using (Html.BeginForm())            {                @Html.ValidationSummary(true)                
        
                    
         
                        
          
           修改文章

修改文章处理action UserEdit(Article article)

[HttpPost]        [UserAuthorize]        [ValidateInput(false)]        public ActionResult UserEdit(Article article)        {            //验证栏目            CategoryRepository _categoryRsy = new CategoryRepository();            var _category = _categoryRsy.Find(article.CommonModel.CategoryId);            if (_category == null) ModelState.AddModelError("CommonModel.CategoryId", "栏目不存在");            if (_category.Model != "Article") ModelState.AddModelError("CommonModel.CategoryId", "该栏目不能添加文章！");            article.CommonModel.Inputer = UserController.UserName;            ModelState.Remove("CommonModel.Inputer");            article.CommonModel.Model = "Article";            ModelState.Remove("CommonModel.Model");            if (ModelState.IsValid)            {                var _article = articleRsy.Find(article.ArticleId);                if (_article == null)//文章不存在                {                    Error _e = new Error { Title = "文章不存在", Details = "查询不到ArticleId为【" + article.ArticleId.ToString() + "】的文章", Cause = "文章已被删除或向服务器提交文章时数据丢失", Solution = Server.UrlEncode("

") };                    return RedirectToAction("ManageError", "Prompt", _e);                }            }            return View(article);        }

这个action也是先验证栏目是否存在，且能添加文章。呵呵，跟添加文章的基本类似。

按F5 浏览器修改篇文章看，能够修改,ok!

代码见：

===========================

1月26日修改：

今天仔细看的时候发现一个问题。在“我的文章”修改链接代码为：@Html.ActionLink("修改","UserEdit",new {id = item.CommonModelId})，这里的id是公共模型的id，再看看ActionResult UserEdit(int id)里面的代码，文章是articleRsy.Find(id))查询返回的。转到定义看看一下代码。

/// 
        /// 查找文章        /// 
        /// 文章id        /// 
             public override Article Find(int Id)        {            return dbContext.Articles.AsNoTracking().Include("CommonModel").SingleOrDefault(a => );        }

这里的id是文章id。所以是用驴唇对了马嘴.... ....

怎么改正呢？既然ActionResult UserEdit(int id)的id指的是公共模型的id，那就写个根据公共模型id查找文章的函数FindByCommonModelId(int commonModelId)就行了。

在ArticleRepository中添加FindByCommonModelId(int commonModelId)函数。

/// 
        /// 根据公共模型id查找文章        /// 
        /// 公共模型Id        /// 
     
      文章
             public Article FindByCommonModelId(int commonModelId)        {            return dbContext.Articles.AsNoTracking().Include("CommonModel").SingleOrDefault(a => a.CommonModelId == commonModelId);        }

将UserEdit(int id)中的return View(articleRsy.Find(id))改为return View(articleRsy.FindByCommonModelId(id))

/// 
        /// 修改文章        /// 
        /// 公共模型id        [UserAuthorize]        public ActionResult UserEdit(int id)        {            return View(articleRsy.FindByCommonModelId(id));        }

完工！
