Question

我完全不熟悉rails并为我的公司编写应用程序，这将有助于更好地跟踪我公司的每个成员参加的MeetUps。

我已经通过rails generate scaffold User...创建了一个简单的CRUD应用程序，并且还创建了一个客户端来连接到MeetUp API（http://www.meetup.com/meetup_api/）。当有人在我的应用程序中创建一个只有他们的名字/姓氏和MeetUp memberId的新用户时，我想点击MeetUp API并确保他们输入的memberId既有效又要他们想要输入的成员ID。 从API中撤回此信息后，我想显示一个包含帐户信息的确认框，以便他们验证，点击“确定”或“取消”，然后创建新用户或告诉他们尝试另一个memberId。这可能吗？下面的相关代码（对格式化道歉）：

创建用户（users_controller.rb）

def create @user = User.new(user_params)

respond_to do |format|
  if @user.hasMeetUpAccount   # Render confirmation here
    if @user.save
      format.html { redirect_to @user, notice: 'User was successfully created.' }
      format.json { render :show, status: :created, location: @user }
    else
      format.html { render :new }
      format.json { render json: @user.errors, status: :unprocessable_entity }
    end
  else
    format.html { render :new, notice: 'No MeetUp account found for #{@user.meetupid}' }
  end
end

end

user.rb

class User < ActiveRecord::Base require 'HTTPClient' def hasMeetUpAccount return HTTPClient.hasMeetUpAccount(["member_id", self.meetupid]) end end

HTTPClient类

require 'httparty' class HTTPClient include HTTParty

def self.GetData(method, method_args)
    HTTParty.get("#{BASE_URI}/#{method}?#{method_args}")
end

def self.hasMeetUpAccount(*args)
    local_args = SetUpArgs(args)

    data = GetData("members", local_args)
    return data
end

谢谢！

据此我明白，如果用户存在，您需要显示确认框，否则执行其他操作。你可以试试这个。

##create action
respond_to do |format|
  if @user.hasMeetUpAccount
     format.html
     format.js
  else
     format.html { render :new }
  end
end




##create.html.erb or any partial inside create.html.erb(_dialog.html.erb)


             <!--  your view logic   -->
            //get the account info from the controller and save it in this hidden field and use it in the js below to show name/any other info that you need 
           <input id="account_name"  type="hidden" value="<%= @account.name %>">


        <script type='text/javascript'>

                 //show the dialog on page load
                 $(function () {  

                 //method to show confirm box
                 function show_confirm_box(){
                 var account_name=$("#account_name").val();
                 if(confirm("Is"+account_name+" your account ?")){
                          ##run ajax or any other thing that you want to do
                    }else{
                        return false;
                    }
              }//method ends
              //call above function when page is loaded and when you have the account name after 3 seconds,you can also use lenght() to verify if account_name hidden element is not empty
              timeout = setTimeout('show_confirm_box()', 3000);
             //clear timeout
              clearTimeout(timeout);
               });

        </script>

是否可以从轨道控制器渲染确认框？
