How to fire a get request between rails and ember

I am new to frontend development,I am using rails and ember to built a sample app .

in rails , i have a function as below

def get_id 
      first_id = User.first.id
     render json: { id: first_id , type: "master"} 
end 

I want to fire a GET request from ember side to call the get_id in ember side which will return the required response . thanks .
