AJAX窗體不通過params [：id]

Question

我在視圖中使用簡單的ajax切換部分，以允許用戶將消息切換爲已讀或未讀。當我切換時，我得到一個失敗。

MessagesController＃show無法找到沒有ID的MessageCopy。
應用跟蹤：messages_controller.rb：在「顯示」（行動的第一線）

show.html.erb 
    <%= render :partial => "read_unread_buttons" %> 

# read_unread_buttons partial 
    <div id="read_buttons" class="ajaxButtonText"> 
    <% if @message.read == true %> 
    <%= link_to "Mark Unread", 
    {:url => {:action => "read_unread_toggle", :id => @message.id}, 
    :update => {:success => "read_buttons", :failure => "Error"}}, 
    {:class=>"messageButton", :id => "markUnread"}, :remote => true %> 
    <% else %> 
    <%= link_to "Mark as Read", 
    {:url => {:action => "read_unread_toggle", :id => @message.id}, 
    :update => {:success => "read_buttons", :failure => "Error"}}, 
    {:class=>"messageButton", :id=>"markUnread"}, :remote => true %>  
    <% end %> 
    </div> 

# messages controller 
    def show 
    @message = current_user.received_messages.find(params[:id]) 
    @message.read = true 
    @message.save(:validate => false) 
    render :layout => "messages" 
    end 

    def read_unread_toggle 
    @message = current_user.received_messages.find(params[:id]) 
    @message.read = !@message.read 
    @message.save(:validate => false) 
    render :partial => "read_unread_buttons", :locals => {:message => @message, :id => params[:id] }, :layout => false 
    end

首先21，我建議使用生成的路徑URL方法生成的HREF，你會看到這在下面的例子中。

其次，我認爲你的routes.rb看起來是這樣的：

resources :messages do 
    member do 
    put 'read_unread_toggle' 
    end 
end 

然後你read_unread_buttons部分應該是這樣的

# read_unread_buttons partial 
    <div id="read_buttons" class="ajaxButtonText"> 
    <% if @message.read == true %> 
    <%= link_to "Mark Unread", read_unread_toggle_message_path(@message), 
    { :update => { :success => "read_buttons", :failure => "Error" } }, 
    { :class => "messageButton", :id => "markUnread" }, { :method => :put, :remote => true } %> 
    <% else %> 
    <%= link_to "Mark as Read", read_unread_toggle_message_path(@message), 
    { :update => { :success => "read_buttons", :failure => "Error" } }, 
    { :class => "messageButton", :id=>"markUnread" }, { :method => :put, :remote => true } %>  
    <% end %> 
    </div> 

具體來說，您忘了指定的方法的HTTP方法鏈接應該使用。
