How can I expand associations more than one level deep? Right now I can expand reviews but am not sure how to also expand the patient_profile_id?
class Review
belongs_to :patient_profile
end
render json: doctors.to_json(
:include => {:reviews => {:include => :patient_profile_id }}
)
I'd highly suggest you check out the jbuilder gem. There's a great railscast that explains it's usage.
Basically, you will have to add a jbuilder file into your views, that gives you allot more control over your json.
For your specific use case you'd use something like this:
doctors/index.json.jbuilder
json.doctors @doctors do |json, doctor|
json.(doctor, :id, :name)
json.reviews doctor.reviews do |json, review|
json.(review, :id, :rating, :patient_profile_id)
json.patient_profile review.patient_profile do |json, profile|
json.(profile, :id, :name, ... ) # attributes of the profile
end
end
end
Check for overriding as_json method
