Hi, I am new to Rails.
Been struggle finding solution for soooo long. Too long I think.
I have nested form:
<%= f.fields_for :items do |i| %>
<%= render ‘item_fields’, :f => i %>
<% end %>
<%= link_to_add_association ‘+ product’, f, :items %>
with item_fields partial:
<%= f.select :product_id,
Product.all.collect {|p| [p.name, p.id,
{‘data-unit_cost’=>p.sell_price},
{ class: ‘product-chosen’, id:
‘product-select’} %>
<%= f.input :sell_price,
id: “price-input” %>
<%= link_to_remove_association image_tag(“delete.png”), f
%>
and coffee script:
$(“#product-select”).change →
unit_cost = $(‘#product-select :selected’).data(‘unit_cost’)
$(‘#price-input’).val(unit_cost)
The idea is everytime product is selected, it store sell_price as value
for
sell_price input.
What I get is:
- If I use ‘product-select’ and ‘price-input’ as class, the result is,
the
second row will duplicating the value from first row.
- If ‘product-select’ and ‘price-input’ as id, the second row value is
empty.
Gem I use: Cocoon, Simple_form, Chosen. The behaviour is the same
without
using Simple_form and Chosen gems.
I see that fields_for block will create hidden_field_id which I think
could
solve this, but I don’t know how to access it and use it in script.
Any help would be appreciated.
