If you expect to get back one record for a given patient_id it could be more readably expressed as: @editpatient = Editpatient.find_by_patient_id(params[:patient_id]) (assuming you fix your form to pass 'patient_id'). > and in the view i have <%= @data %> Which is opaquely named, and hides the fact that you're fetching an array. > this displays all the data but i only want one field.
