Question

我有一个link_to使用remote：true通过POST对特定功能进行切换，在点击时切换它的状态。但是，每当我尝试切换它时，rails仅在第一次尝试时响应404，但它在第二次尝试时正常工作。该路线正常工作和配置，但不知道为什么第一次点击总是返回404.这发生在Chrome和Firefox上，仅限生产，开发工作正常。

我在Ubuntu上使用Rails 4.1和Ruby 2.1.1p76，Unicorn + Nginx

这是日志消息：

的routes.rb

    post "/recommend/:text_id/" => "users#recommend", as: "recommend"

    %span#recommendation-status.action-name= t(:recommend, count: @current_user ? (@current_user.recommended?(text) ? 1 : 0) : 0)

text.js.coffee

@text.actions.recommend.on 'ajax:success', (e, data) ->
    self.text.actions.recommend.attr 'data-recommended', data.recommended
    $('#recommendation-status').text data.status
    $('#recommendation-count').text data.counter
    return

users_controller.rb

def recommend
    text = Text.friendly.find(params[:text_id])
    @user.recommend(text)
    respond_to do |format|
      status = I18n.t(:recommend, count: @user.recommended?(text) ? 1 : 0)
      text.reload
      counter = text.recommendations_count
      format.json {render json: {status: status, recommended: @user.recommended?(text), counter: counter}, status: :ok}
    end
  end

我已经google了一下，并没有发现任何关于这个问题或类似的东西。任何帮助将非常感谢！感谢

您的路线有问题，我没有找到在资源中没有member或collection的路线的文档。使用您的配置路由，链接可能匹配：

u/recommend/:text_id

所以你应该使用：

member do 
  post "/recommend/:text_id/" => "users#recommend", as: "recommend" 
end

在您的资源路线中。

我认为它有错误，因为路由错过了用户资源的id。使用member do ... end将匹配您的预期路线：

/u/:id/recommend/:text_id

link_to ... remote：true，方法：post总是在第一次尝试时失败
