According https://github.com/nathanvda/cocoon#link_to_add_association you should be able to pass a function to data-association-insertion-node
I have tried this:
<%= link_to_add_association 'Add Timeslot', f, :timeslots, :data => {'association-insertion-node' => 'get_row()'} %>
And this:
<%= link_to_add_association 'Add Timeslot', f, :timeslots, :data => {'association-insertion-node' => 'get_row'} %>
And this (getting desperate):
<%= link_to_add_association 'Add Timeslot', f, :timeslots, :data => {'association-insertion-node' => 'function get_row(node){var row = "<tr></tr>";$("#table_body").append(row);return row;}'} %>
But none of them work.
Javascript:
function get_row(node){
var row = "<tr></tr>"
$("#table_body").append(row);
return row
}
I am trying to add a tr to a table and then append the nested timeslot form to the tr.
At the moment this is not possible what you are trying to do. When setting the data-association-insertion-method like this, it will just be a string in javascript, and not a reference to a method.
As documented in the README, you have to do the following (assuming you gave your links a class .add-timeslot):
$(document).on('turbolinks:load', function() {
$(".add-timeslot a").
data("association-insertion-method", 'append').
data("association-insertion-node", function(link){
return link.closest('.row').next('.row').find('.sub_tasks_form')
});
});
(the example is almost verbatim copied from documention for demonstration purposes only --you will have to fill in your get_row function)
