如何在create.js.erb文件中测试哪个页面发送了AJAX请求？

Question

I have two different pages in my app that call an AJAX request to add a new phone_number ( to a key_contact ). These are the companies page ( key_contact belongs_to company ) and the sales_opportunity page ( where the sales_opportunity has_many key_contacts through sale_contacts ). Both pages have a table of key_contacts that I want to reload once the phone_number is added. I want to use the create.js.erb file to reload ONLY the table that should be on the page ( the table on sales_opportunities is different to the one on the companies page ). As such I need to test the URL of the page that sends the AJAX request and then render a partial accordingly. I've tried the below, but it isn't working. Can anyone help me work out why?

//update the key contact table with the new phone number, and close the modal
$('#phone_number_modal').modal('hide')
    .clear_previous_errors();
resetForm($('#new_phone_number'));
$input = $('#phone_number_error');
$input.closest('.form-group').removeClass('has-error').find('.warning-block').html('');
//render the newly added key contact to the table if the AJAX call succeeded

<% if (URI(request.referer).path == '/companies') %>
$('#key-contacts-table-div').html("<%= escape_javascript(render :partial => 'shared/key_contacts_table')%>");
<% end %>

<% if (URI(request.referer).path == '/sales_opportunities') %>
$('#sale-contacts-table-div').html("<%= escape_javascript(render :partial => 'sale_contacts/table')%>");
<% end %>
$('.alert').remove();
$('#key-contacts').DataTable({
    retrieve: true,
});

Instead of using referer , you can just add an extra params in your url, let's say you call it :action_type . Then in your controller, you can do:

class AAAController < ActionController::Base
  def your_action
    if params[:action_type] == "companies"
      render "create_1"
    elsif params[:action_type] == "sales_opportunities"
      render "create_2"
    end
  end
end

Then you can put different logic in create_1.js.erb or create_2.js.erb separately.
