Question

我有以下代码向我的控制器方法发出ajax请求以获取给定网址的内容类型：

    $("#wiki_form_url").change(function () {
        $.ajax({
            type: "GET",
            url: "/wiki_forms/content",
            data: {
                input_url: $("#wiki_form_url").val()
            },
            dataType: "text"
        }).done(function (data) {
                    // `data` contains the content-type
                    alert('Success');
                    console.log(data);
//                    alert(data);
                }).fail(function () {
                    alert("failed AJAX call");
                });
    });

我的wiki_forms控制器中有一个名为content的内部方法，我在做什么：

  def content

    req = open(params[:input_url])
    render :text => req.content_type
    puts  "type is : #{req.content_type}"

  end

在我的route.rb文件中我有：

 match "/wiki_forms/content" => 'wiki_forms#content'

但是，当我尝试发出ajax请求时，我会收到错误。我的控制台看起来像这样：

Started GET "/wiki_forms/content?input_url=http%3A%2F%2Fwww.ofdp.org%2Fbenchmark_indices%2F25" for 127.0.0.1 at 2013-03-28 14:08:42 -0400
Processing by WikiFormsController#show as TEXT
  Parameters: {"input_url"=>"http://www.ofdp.org/benchmark_indices/25", "id"=>"content"}
  WikiForm Load (0.3ms)  SELECT "wiki_forms".* FROM "wiki_forms" WHERE "wiki_forms"."id" = ? LIMIT 1  [["id", "content"]]
Completed 500 Internal Server Error in 3ms

ActiveRecord::RecordNotFound (Couldn't find WikiForm with id=content):
  app/controllers/wiki_forms_controller.rb:23:in `show'

为什么在这里调用show方法，因为我在ajax调用中指定了content方法？如何使这项工作？请帮忙

              root        /                              wiki_forms#index

routes.rb文件的排序很重要。

rake routes显示

        wiki_forms GET    /wiki_forms(.:format)          wiki_forms#index
                   POST   /wiki_forms(.:format)          wiki_forms#create
     new_wiki_form GET    /wiki_forms/new(.:format)      wiki_forms#new
    edit_wiki_form GET    /wiki_forms/:id/edit(.:format) wiki_forms#edit
         wiki_form GET    /wiki_forms/:id(.:format)      wiki_forms#show
                   PUT    /wiki_forms/:id(.:format)      wiki_forms#update
                   DELETE /wiki_forms/:id(.:format)      wiki_forms#destroy
              root        /                              wiki_forms#index
wiki_forms_content        /wiki_forms/content(.:format)  wiki_forms#content

所以

         wiki_form GET    /wiki_forms/:id(.:format)      wiki_forms#show

首先匹配，:id具有值字符串“content”

移动你的

match "/wiki_forms/content" => 'wiki_forms#content'

在routes.rb中更高。

Ajax在我的Rails应用程序中不起作用
