Hi ,
I thing you are trying to get the @todays_order_of_patient object
including the child object @todays_order_of_patient.courses in
a nested json. If that is what you are trying to accomplish try this:
replace:
respond_with(@todays_order_of_patient, :location => nil, :include
=> :courses)
with this:
respond_with(@todays_order_of_patient.to_json( :include
=> :courses), :location => nil)
OR version 2 :
remove:
respond_to : json - on the top
and replace the controler respond with:
respond_to do |format|
format.html
format.json { render :json => @todays_order_of_patient
object.to_xml(:include => :courses) }
end
