I'm working on populating this dropdown and finding myself having some
trouble even though in theory it would be pretty simple. I'm used to rails
4 and we are using rails 3 on this project as well as haml which I'm
familiar with, but not super comfortable with.
*_extra_fields.html.haml*
= form.input :category_id, as: :select, collection: Category.all.map{|x|
[x.name,x.id]}, input_html: {:style => "width:300px"}, :include_blank =>
true
= form.input :sub_category_id, as: :select, collection:
@package.category.sub_categories.map{|x| [x.name,x.id]}, input_html:
{:style => "width:300px"}, :include_blank => false
