Question

WARNING: Can\'t verify CSRF token authenticity

I think

Answer 1

The best way to do this is actually just use <%= form_authenticity_token.to_s %> to print out the token directly in your rails code. You dont need to use javascript to search the dom for the csrf token as other posts mention. just add the headers option as below;

$.ajax({
  type: 'post',
  data: $(this).sortable('serialize'),
  headers: {
    'X-CSRF-Token': '<%= form_authenticity_token.to_s %>'
  },
  complete: function(request){},
  url: "<%= sort_widget_images_path(@widget) %>"
})
