Formtastic select list
forms, formtastic, ruby-on-rails
Solution
There's a `:collection` option for the select input.
<%= form.input :shop_category, :collection => @shop.ShopCategories %>
So you can, by providing a Hash to that collection attribute, display the categories you need, with the required conditions.
Problem
``` <% semantic_form_for(@product, :html => {:multipart => true}) do |f| %> <% f.inputs do %> <%= f.input :name %> <%= f.input :price %> <%= f.input :pno %> <%= f.input :description %> <%= f.input :shop_category %> <% end %> <% end %> ``` Product belongs to Shop_category, Shop_category belongs to Shop. How to change the line : ``` <%= f.input :shop_category %> ``` To show only shop_categories that belongs to Shop with id for example 15 instead of showing all shop_categories in the select box ?
