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

Rails 5+ syntax:

Person.includes(:notes).where(notes: {important: true})

Nested:

Person.includes(notes: [:grades]).where(notes: {important: true, grades: {important: true})
