People I figure out this problem
The problem was solved with this
# models/product.rb
accepts_nested_attributes_for :stocks
# views/product/_form.erb
<% for color in Color.all %>
<div>
<%= check_box_tag
"product[stocks_attributes][][color_id]",
color.id, @product.colors.include?(color) %>
<%= color.name %>
<%= text_field_tag
"product[stocks_attributes][][qtd]" %>
</div>
<% end %>
