Rails includes with conditions

Question

Is is possible in Rails > 3.2 to add conditions to the join statement generated by the includes method?

Let\'s say I have two models, Person and Note. E

Answer 1

For people interested, I tried this where a record attribute was false

Lead.includes(:contacts).where("contacts.primary" => false).first

and this doesn't work. Somehow for booleans only true works, so I turned it around to include where.not

Lead.includes(:contacts).where.not("contacts.primary" => true).first

This works perfectly
