Mercury编辑器未在Rails 4.2中保存编辑的值

Question

我按照Railscast教程设置了水星编辑器。

mercuy.js

$(window).bind('mercury:ready', function() {
  var link = $('#mercury_iframe').contents().find('#edit_link');
  Mercury.saveUrl = link.data('save_url');
  link.hide();
});

$(window).bind('mercury:saved', function() {
  window.location = window.location.href.replace(/\/editor\//i, '/');
});

视图/报价/show.html.erb

<p><%= link_to "Edit Page", "/editor" + request.path, id: "edit_link", data: {save_url: mercury_update_quotation_path(@quotation)} %></p>

mercury.html.erb

  new Mercury.PageEditor(saveUrl, {
    saveStyle:  'form', // 'form', or 'json' (default json)
    saveMethod: null, // 'PUT', or 'POST', (create, vs. update -- default PUT)
    visible:    true  // boolean - if the interface should start visible or not
  });

routes.rb

  resources :quotations  do
    member { post :mercury_update}
  end

它显示以下错误

Mercury was unable to save to the url: http://localhost:3000/quotations/1

控制台输出

Started PUT "/quotations/1" for 127.0.0.1 at 2015-03-07 19:20:49 +0530

AbstractController::ActionNotFound (The action 'update' could not be found for QuotationsController):

它对静态id运行得很好，但不是这样。请帮我解决这个错误。

Answer 1

你的错误告诉你

ActionNotFound 

这意味着您的QuotationsController中缺少mercury_update。尝试添加

def mercury_update
  quote = Quotations.find(params[:id])
  quote.FIELD_FROM_YOUR_DB = params[:content][:quotation_content][:value]
  quote.save!
  render text:""#tells mercury of successful save (I think)
end

如果这不起作用，请尝试检查您的控制台是否传递了水星参数。它应该看起来像这样

Started PUT "/quotations/1/mercury_update" for ...
  Parameters:{"content"=>{...}}

请注意，这是一个PUT请求，这就是Mercury告诉您它正在做的事情。因此，需要更新路径

resources :quotations do
  member do
    put 'mercury_update' #this may change your path to mercury_update_quotation_page_path(@quotation)
  end
end

另外，确保在config/routes.rb中没有两次定义resources :quotations。我按照该教程定义了它，然后运行

rails g scaffold quotations

以便自动生成视图等。此命令在我的config/routes.rb顶部再次定义引号为

resources :quotations
#...
resources :quotations do #... This was my definition

因此忽略了我对成员'mercury_update‘的定义。

最后，让我知道你保存的回复是否起作用，就像我的不起作用。GL！
