C# 从部分视图中的表单发布-为什么它会触发错误的控制器操作？

请耐心听我描述这个问题

使用局部视图的MVC3应用程序。无法从其父模型的详细信息视图在局部视图中发布注释表单

参考

ArticleViewModel

有一个

CommentsViewModel

集合，因此存在OTM关系

详细信息视图 _注释编辑器局部视图 情景/问题

Http请求

/Article/Details/{slug}

正确呈现文章、评论和编辑器表单

编辑器按预期工作，但单击Submit时，我注意到正在调用控制器上的Details操作，而不是HttpPost注释操作

如您所见，Razor表单帮助程序使用

POST

在

文章

控制器上指定

注释

操作

问题: 为什么会这样？我错过了什么？

笨蛋奖

答案是路由。

仔细看Fiddler，我实际上是在向

/article/comment

发送一个

POST

请求，所以我检查了我的路由。。。我怎么会错过这个，我不知道：

routes.MapRoute("Article-Create", "article/create", new { controller = "Article", action = "Create" });
routes.MapRoute("Article-Edit", "article/edit/{slug}", new { controller = "Article", action = "Edit" });
routes.MapRoute("Article-Delete", "article/delete/{slug}", new { controller = "Article", action = "Delete" });
routes.MapRoute("Article", "article/{slug}", new { controller = "Article", action = "Details" });
routes.MapRoute("Articles", "articles", new { controller = "Article", action = "Index" });

注释操作没有明确的路由。有一个获取文章的catch-all-REST-ish路由（

article/{slug}

）。因此，在点击默认路径之前，评论帖子由它处理

我的具体解决方案（我喜欢显式路由——即使这会给我带来麻烦）是为注释添加一条路由，这与catch all

article/{slug}

模式差不多：

routes.MapRoute("Article-Comment", "article/comment", new { controller = "Article", action = "Comment" });

问题解决了。尴尬

public ActionResult Details(string slug) {
    return View(_articleService.Get(slug));
}

[HttpPost]
public ActionResult Comment(string slug, CommentViewModel comment) {
    if(ModelState.IsValid) {
        _articleService.AddComment(comment, slug);
    }
    return RedirectToAction("Details", new { Slug = slug });
}

routes.MapRoute("Article-Create", "article/create", new { controller = "Article", action = "Create" });
routes.MapRoute("Article-Edit", "article/edit/{slug}", new { controller = "Article", action = "Edit" });
routes.MapRoute("Article-Delete", "article/delete/{slug}", new { controller = "Article", action = "Delete" });
routes.MapRoute("Article", "article/{slug}", new { controller = "Article", action = "Details" });
routes.MapRoute("Articles", "articles", new { controller = "Article", action = "Index" });

routes.MapRoute("Article-Comment", "article/comment", new { controller = "Article", action = "Comment" });
