在描述问题时,请多多包涵.

使用局部视图的MVC3应用程序.无法从其父模型的“详细信息”视图中的部分视图中发布“评论”表单.

供参考,ArticleViewModel具有CommentsViewModel的集合,因此存在OTM关系.

详细资料检视

@model ArticleViewModel

// Renders the Article and its Comments - no forms, just display markup
// A nested _Comments partial is used to render the article's comments.
@Html.Partial("_Article", Model)

// Renders HTML and Javascript for the Pagedown editor - POST form inside.
@Html.Partial("_CommentEditor", new CommentViewModel())

@section scripts { /* code here for validation and the javascript editor */ }

_CommentEditor部分视图

@model CommentViewModel

@using (Html.BeginForm("Comment","Article",FormMethod.Post)) {
    @Html.TextAreaFor(m => m.Content)
    <input type="submit" value="Submit" />
    <input type="reset" value="Clear" />    
}

物品管制员

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 });
}

场景/问题

> / Article / Details / {slug}的Http请求正确呈现了文章,其注释和编辑器表单.
>编辑器按预期工作,但是在单击Submit时,我注意到我的控制器上的Details操作被调用,而不是HttpPost Comment操作.

如您所见,Razor Form帮助器使用POST在Article控制器上指定了Comment操作.

为什么会这样呢？我想念什么？

冠军奖！

答案是路由.

与Fiddler往前看,我实际上是向/ article / comment发送POST请求,所以我检查了路由…我怎么错过了这个,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" });

评论操作没有明确的路线.在获取文章(article / {slug})时,有一条通俗易懂的REST式路线.因此,在击中默认路由之前,它正在处理Comment POST.

我的特定解决方案(我喜欢显式路由-即使在遇到麻烦时也是如此)是添加一条评论路线,仅适用于所有文章/ {slug}模式：

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

问题解决了.不好意思
