Ruby on Rails Wednesday, June 30, 2010

Consider the following setup:

class Parent < ActiveRecord::Base
has_many :children

class Child < ActiveRecord::Base
belongs_to :parent

And this console session:

>> p = Parent.find 41
>> p.some_attr = 'some_value'
>> c =
>> c.parent

By watching my log files, I can see that c.parent is querying the db
for the parent object. I want instead to access the existing in-memory
object (p), because I need access to the parent's some_attr value,
which is not yet stored in the database. Is there any way of doing
this? c.parent(force_reload=false) doesn't get me there.
