Rails 使用 AJAX 参数从视图发送到控制器中的自定义操作

Question

我在操作时遇到问题。我想从视图发送到自定义控制器操作，但出现错误：

Routing Error No route matches [GET] "/send_email_representing"

在控制台中，我在看：

/send_email_representing?data_1=asas%2C.cs%2Csasn&data_2=a%2Cs.a%2Cc.d.cdsmoidnndvsodsn-nqw928h3%26Siabic&data_3=33

自定义操作

def send_email_representing
 @message = params[:data_1]
 @subject = params[:data_2]
 @user_representing = User.find(params[:data_3])
 SendMessageToUserMailer.email(@user_representing, @message, @subject).deliver_now
 render html: 'Good'.html_safe
end

视图中的函数

$("#sendEmailtoRepresenting").click(function() {


    var subject = $("#form1").val();
    var message = $("#form7").val();
    alert(subject+" "+message);
    var representing_id_1 = $("#hiddenEmailInput").val();

    var data_value = [subject,message,representing_id_1];
    console.log(JSON.stringify(data_value));

    if ((subject != null && subject != "") && (message != null && message != "") && (representing_id_1 != null && representing_id_1 != ""))
    {
        url = "/send_email_representing";
        $.ajax({
          type: "GET",  
          //dataType: "json",
          //http://0.0.0.0:3000/admin/send_email_representing/1,subject,message
          url: url,
          data: {data_1: data_value[0], data_2:data_value[1], data_3:data_value[2] },
          contentType: "application/json",
          success: function (data) {

            if (data == "Good"){
                displayEmailSuccesMenssage("Email has been sent");
            }           
          },
          error: function (data) {
              console.log("Error: "+data);
              alert("Error");
          }
        });

    } else {
        alert("Error");
    }   
    return false;

});

路线

get "send_email_representing" => "users#send_email_representing", :as => :send_email_representing

不知道是不是我定义错了route，必须要放参数，不然不是GET if not POST，或者controller里面的action，但是我注意到params正在发送是正确的，为此在错误页面：

Request
Parameters:
{"data_1"=>"asas,.cs,sasn", "data_2"=>"a,s.a,c.d.cdsmoidnndvsodsn-nqw928h3&Siabic", "data_3"=>"33"}

命令制作路线

admin_send_email_representing GET    /admin/send_email_representing(.:format)    admin/users#send_email_representing

我希望这能帮到我。谢谢。

根据您的 rake routes 命令的输出，您发出请求的路由在 admin 范围内，因此您应该相应地将您的 JS 更改为：

  if ((subject != null && subject != "") && (message != null && message != "") && (representing_id_1 != null && representing_id_1 != ""))
    {
        url = "<%= admin_send_email_representing_path %>"; //<-- add admin scope here
        $.ajax({
