I have some orders with nested items and the items have nested kinds. When i do a form_for @order in a view, then i would like to hide all the items that have their :registered attribute set to true
<% form_for @order do |f| %>
<% f.fields_for :items do |ff| %>
<%# show all the items that have :registered == false %>
<% end %>
<% end %>
or
def register
@order = Order.find(params[:id])
# Sort out the :registered == true
end
You can try something like this:
<% form_for @order do |f| %>
<% f.fields_for :items do |ff| %>
<% next if ff.object.registered %>
<%# show all the items that have :registered == false %>
<% end %>
<% end %>
Or you can create a second association for unregistered items:
class Order < ActiveRecord::Base
has_many :unregistered_itmes, :class_name => "Item", :conditions => { :registered => false }
end
And then you can do something like this:
<% form_for @order do |f| %>
<% f.fields_for :unregistered_items do |ff| %>
<%# show all the items that have :registered == false %>
<% end %>
<% end %>
