Question

路线：

  resources :news_items, :path => 'news', :as => 'news' do
   collection do
     get 'all' => 'news_items#news'
  end

控制器：

def new
  @news = NewsItem.new
  @news.file_uploads.build

  respond_to do |format|
    format.html # new.html.erb
    format.json { render json: @news }
  end
end

形式：

<%= form_for(@news, :html => {:class=>'form-stacked', :multipart => true}) do |f| %>
  <% if @news.errors.any? %>

当我运行rake路线时

          all_news_index GET    /news/all(.:format)                 {:action=>"news", :controller=>"news_items"}
          news_index GET    /news(.:format)                     {:action=>"index", :controller=>"news_items"}
                     POST   /news(.:format)                     {:action=>"create", :controller=>"news_items"}
            new_news GET    /news/new(.:format)                 {:action=>"new", :controller=>"news_items"}
           edit_news GET    /news/:id/edit(.:format)            {:action=>"edit", :controller=>"news_items"}
                news GET    /news/:id(.:format)                 {:action=>"show", :controller=>"news_items"}
                     PUT    /news/:id(.:format)                 {:action=>"update", :controller=>"news_items"}
                     DELETE /news/:id(.:format)                 {:action=>"destroy", :controller=>"news_items"}

当我去'/ news / new'时，我得到了：

No route matches {:path_prefix=>"news", :controller=>"news_items", :format=>nil}

当我去'/ news / 4 / edit'时，我得到：

No route matches {:path_prefix=>"news", :action=>"show", :controller=>"news_items", :format=>nil, :id=>#<NewsItem id: 4,...

Answer 1

我认为问题出在form_for(@news)行。

这将创建一个表单，其URL由@news类推断。

这似乎属于NewsItem课程，因此它会尝试链接到news_items_path。

您应该尝试明确说明网址。

form_for(@news, :url => news_path(@news))

指定'path'时没有路由匹配
