I am a ruby on Rails Novice and I am having an extremely frustrating problem -
not sure whether acts_as_tree plug in is causing this or not (or me lacking a
fundamental misunderstanding of rails)
I have the following table schema:
create_table "destinations", :force => true do |t|
t.string "name"
t.string "description"
t.integer "commissions_rate", :default => 0
t.integer "destinations_count", :default => 0
t.integer "position"
t.datetime "created_at"
t.datetime "updated_at"
end
and model def:
class Destination < ActiveRecord::Base
attr_accessible :id, :name, :parent_id, :centre_longitude, :centre_latitude,
:commissions_rate, :position, :startzoom, :description, :destinations_count
acts_as_tree :counter_cache => true
end
I am trying to adjust the update method in my controller so that if the parent
commissions_rate is modified the "children" records of the parent are
automatically updated with this value, code as follows:
def update
@destination = Destination.find(params[:id])
@rate = @destination.commissions_rate || 0
@children = @destination.children
if (@destination.destinations_count > 0)
for child in @children do
child.commissions_rate = @rate
end
end
respond_to do |format|
if @destination.update_attributes(params[:destination])
flash[:notice] = 'Destination was successfully updated.'
.........
end
The form only send data for the parent model (not using nested model)
Everything works when I test the above code in the Rails console however when
running the server the children are failing to have the commission_rate
variable updated.
Would appreciate any help anyone can provide me.
Thanks
David
