I want to get the id of an element that I have created using a query-AJAX-POST-Request, but none of the approaches that I have found so far, had worked.

Currently I am stuck here

Controller:

def createuserlink
  @new_element = Link.new(element_params)
  @new_element.save
  respond_with @new_element  
end

Jquery:

  $.ajax({
    url: "links/createuserlink",
    type: "POST",
    data: my_data
  }).done(function( data, textStatus, request ) {
    alert(data);
  });

The Request works and the new_element gets created, but the alert-message shows me the HTML-code of the new_element/show page. I can see the id of the returned page in the browser dev-tools (like foo.com/element/42), but I don't know how to access it.

I tried to use getResponseHeader as suggested here, but it only works for parameters (like foo.com?element=42).

I also tried respond_with @new_element.id, but he didn't liked the syntax.

What is the easiest and recommended way to get back the id?

    Create createuserlink.js.erb or createuserlink.js.haml file to show your data. Please refer this answer. http://stackoverflow.com/a/18900799/2681997. – Ajay Barot Mar 07 '17 at 18:41

looks like you want json, not a template, instead of respond_with, why not try:

def createuserlink
  @new_element = Link.new(element_params)
  @new_element.save
  render json: @new_element.to_json
end
