` `ActionController::RoutingError ( Heroku中没有路由匹配[GET]`路由问题，但在本地主机上工作

Question

我已经通过Thumbs_Up宝石在我的应用程序中建立了投票。它在我的localhost上运行得很好，但是当我试图在Heroku上投票时，我的Heroku日志中出现了这个错误：

ActionController::RoutingError (No route matches [GET] "/jokes/wise-police-officer/vote_up"):

下面是我的jokes模型的路线：

resources :jokes do
  patch :approve, on: :member
  patch :reject, on: :member
  member do
    post :vote_up
    post :vote_down
  end
end

同样，这很奇怪，因为它在localhost中运行得很好。有人有类似的问题吗？

下面是投票链接的HTML/ERB：

        <div class="width: 100%"><%= link_to " ", vote_up_joke_path(joke), class: 'upvote glyphicon glyphicon-chevron-up', method: :post, style: "margin-right: 0; margin-left: 0" %></div>
        <div class="width: 100%"><h3 style="margin-top: 0; margin-bottom: 0"><strong><%= joke.plusminus %></strong></h3></div>
        <div class="width: 100%"><%= link_to " ", vote_down_joke_path(joke), class: 'downvote glyphicon glyphicon-chevron-down', method: :post, style: "margin-right: 0; margin-left: 0" %></div>

下面是我的bundle exec rake routes输出的全部内容：

Answer 1

我联系了heroku支持部门，他们在推荐我使用AJAX时得到了与@AjitSingh类似的答复：

我明白你说的了。与其依赖标记，我建议使用按钮或表单进行AJAX调用来完成适当的POST请求。

不过，AJAX现在比我的技术水平要高一点。我还在ROR API上找到了这个关于使用link_to的小宝石(不是双关语)。

方法: HTTP谓词的符号-此修饰符将动态创建HTML表单，并立即提交表单，以便使用指定的HTTP谓词进行处理。对于让链接在危险的操作中执行POST操作很有用，比如删除一个记录(搜索机器人可以在你的站点上执行搜索操作)。受支持的动词有:post、:delete、：修补程序和:put。注意，如果用户禁用了JavaScript，请求将返回到使用GET。如果使用了href：'#‘，并且用户禁用了JavaScript，单击该链接将没有任何效果。如果您依赖POST行为，则应该使用request对象的post、delete、修补程序或put方法，在控制器的操作中检查它。

最后，我咨询了this的建议，所以发布并使用了button_to而不是link_to，解决了这个问题。呼。

Answer 2

它提交了一个“get”请求，并且需要提交一个post请求。确保在处理“向上投票”的method: :post调用中指定了link_to。

Answer 3

确保在你的application.js中有跟随者

//= require jquery
//= require jquery_ujs

jquery-ujs从超链接发出非获取请求。即使link_to方法使用data-method=post生成适当的html，您也需要jquery-ujs来发出非GET请求，其他明智的方法是，您的链接自然会创建GET请求。
