I'm having a rather weird problem using Rails 4, Turbolinks and a remote form. I have a form looking like:
<%= form_for [object], remote: true do |f| %>
<td><%= f.text_field :name, class: 'form-control' %></td>
<td><%= f.email_field :email, class: 'form-control' %></td>
<td><%= f.submit button_name, class: 'btn btn-sm btn-primary' %></td>
<% end %>
This form adds (creates) a new object. It does however not always work:
When disabling Turbolinks for this link, the page worked perfectly.
I have two questions:
Thanks in advance.
Solution
Thanks to @rich-peck, the solution was to add a piece of javascript that manually submits the form upon clicking the button:
<%= javascript_tag do %>
var id = "#<%= dom_id(f.object) %>";
var inputs = $(id).parent().find('input');
console.log(inputs);
$(id).parent().find('button').on('click', function(e) {
e.preventDefault();
$(id).append(inputs.clone());
$(id).submit();
});
<% end %>
This code adds javascript to the form table row, getting the inputs, appending them to the ID and submitting the form. The preventDefault(); prevents the query from getting sent twice when the page is refreshed and the form actually works.
Turbolinks
As mentioned, the problem with Turbolinks is that it reloads the <body>
part of the DOM with an ajax call - meaning JS is not reloaded, as it's in the head
The typical way around this issue is to delegate
your JS from the document
, like this:
$(document).on("click", "#your_element", function() {
//your code here
});
Because document
is always going to be present, it will trigger the JS continuously
Remote
With your issue, it's slightly more tricky
The problem is you're relying on the JQuery UJS (unobtrusive JavaScript) engine of Rails, which is difficult to remedy on its own
We've never had this issue & we use Turbolinks all the time - so I suppose the problem could be with how you're constructing your form / handling the request. This GitHub seemed to recreate the issue, and it was to do with the table
Maybe you could try:
<%= form_for [object], remote: true do |f| %>
<%= f.text_field :name, class: 'form-control' %>
<%= f.email_field :email, class: 'form-control' %>
<%= f.submit button_name, class: 'btn btn-sm btn-primary' %>
<% end %>
