I have a parent with has_many children. The children have a column
‘blah’. IF I do the following:
The sql exectued is:
select * from blah where parent_id = 1 and blah = 42 select * from blah where parent_id = 1
The first line of sql is what I want. The second appears to be
ActiveRecord loading up all of parent.children. This I don’t want b/c
children is huge.
How do I avoid that and use idiomatic ActiveRecord?
