Product model is as follows
class Product < ActiveRecord::Base
belongs_to :product_category
has_and_belongs_to_many :variant_parameters
I am displaying a collection of variant parameters for the product.
Can be more than one selection box. I want to update the same.
I currently have the following selection code
<%= collection_select(:product, :variant_parameter_ids,
@product_categories_variants_parameters, :id, :parameter, {:prompt =>
true}) %>
I have more than one drop down of variant params associated to the
product.
How do I specify that I need :variant_parameter_ids[] and
not :variant_parameter_ids ?
When I try it I get
undefined method `[]' for :variant_parameter_ids:Symbol
