Hi,

Category Mappings:
<% options = options_from_collection_for_select (@categories,
‘name’,‘id’, @category_ids) %>
<%= select_tag(‘categories_ids[]’, options, {:multiple=>true, :size=>7}) %>
I am getting error:
Couldn’t find Category without an ID
I think it should be:
@title.categories = Category.find(params[:categories_ids]) if
params[:categories_ids]
