OK...so I renamed the table/model/controller and am getting a different error based (likely) on the fact that I forgot to change the name somewhere...
NameError in PatientApplicationsController#create undefined local variable or method `patient_application_params' for #<PatientApplicationsController:0x007f257dbdc9d8> > # POST /patient_applications.json > def create > @patient_application = PatientApplication.new(patient_application_params) > > respond_to do |format| > if @patient_application.save The parameters are as follows: >{"utf8"=>"✓", > "authenticity_token"=>"Rf9oXjSWGjhsPlc9MHMxKEFWPjHSS5sAqDA0Pdsi9nVO+qrlMgDsBEtObej9anvfcI42nigMUHmZ3cWQHbjiRA==", > "patient_application"=>{"patients_ptID"=>"1", > "pharm_manufacturers_phID"=>"1", > "medications_rxnorm_ndc"=>"Tylenol", > "app_status"=>"Pending", > "date_init(1i)"=>"2015", > "date_init(2i)"=>"2", > "date_init(3i)"=>"8"}, > "commit"=>"Create Patient application"} The updated controller is as follows: class PatientApplicationsController < ApplicationController before_action :set_patient_application, only: [:show, :edit, :update, :destroy] #
