read/write_attribute is a great way to enhance default accessors generated by
ActiveRecord. Like this for example:
def price
read_attribute(:price) or "This item is priceless and you are by the way #{User.current.login}"
end
The same however does not seem to be working with associations.
Demonstration:
class Product < ActiveRecord::Base
has_and_belongs_to_many :stores
end
Then
>> a = Product.first
=> #<Product id: 1, name: "awesome product", created_at: "2010-05-07 12:11:00", updated_at: "2010-05-07 12:11:00">
>> a.stores
=> [#<Store id: 1, name: "ikea", created_at: "2010-05-07 12:11:28", updated_at: "2010-05-07 12:11:28">]
>> a.read_attribute(:stores)
=> nil
>>
So, is there some sort of read/write_association? Or, if not, is there a reason not to have one?
