Existe alguma forma que você conheça que posso preencher o valor do text_field como preencho o checkbox, algo como:
<%= text_field_tag "product[stocks_attributes][] [qtd]", :value=>@product.stocks.include?(color) %> mas o include? retorna boolean, eu queria que ele retornasse o valor da posição encontrada da cor. Se existisse esse método já resolveria meu problema.
