Ruby on Rails Ajax调用显示404错误

Question

I am making and ajax call to hit the controller but it is showing the 404 error:

My controller method is like:

def get_user_time
    if(params[:user])
        @user_time_checks = UserTimeCheck.where(:user_id => params[:user])
    end
end

And my route for this is like:

post "user_time_checks/get_user_time"

And my ajax script is like:

 function get_user_time(id) {
     var user_id = id;   
     if(user_id != ''){       
        $.ajax({
          url:"get_user_time?user="+user_id,
          type:"POST",
          success: function(time){
            console.log(time);
          },error: function(xhr,response){
            console.log("Error code is "+xhr.status+" and the error is "+response);
          }
        });
      }
  }

Answer 1

Try this:

$.ajax({
  url:"user_time_checks/get_user_time",
  type:"POST",
  data: {
    user: user_id 
  },  
  success: function(time){
    console.log(time);
  },error: function(xhr,response){
    console.log("Error code is "+xhr.status+" and the error is "+response);
  }
});

Also make sure you really need to do POST method and that rails route does not require specific paramater like :user_id. Basically check the output from

rake routes | grep get_user_time

Your route should be:

post "user_time_checks/get_user_time" => "user_time_checks#get_user_time"

Also, since the purpose of the request is to get some data, you should make it a GET request instead. So:

function get_user_time(id) {
    var user_id = id;
    if(user_id != ''){
        $.get("get_user_time",
                    {user: user_id})
        .success(function(time) {
            console.log(time);
        })
        .error(function(xhr,response){
            console.log("Error code is "+xhr.status+" and the error is "+response);
        });
    }
}

Lastly, maybe you should tell the controller to be able to repond_to json:

def get_user_time
    if(params[:user])
        @user_time_checks = UserTimeCheck.where(:user_id => params[:user])
        respond_to do |format|
            format.html # The .html response
            format.json { render :json => @user_time_checks }
        end
    end
end
