Avançando no aprendizado no Ruby on Rails. Estou com o seguinte problema.
Estou com o seguinte problema em um formulário utilizando has_many through.
Tenho um cadastro onde eu criou formulários dinamicos. Esses formulários dinamicos são inseridos em uma outra tela.
Estou com dificuldade no controller onde eu insiro esses fomulários e na view que faço a inserção.
Appointments -> onde posso ter muito formularios dinamicos (record_forms) Record_Forms -> cadastro dos formulários dinamicos Record_Form_Fields -> campos do formulario dinamico Appointment_Record_Forms -> tabela para relacionamento entre Appointments e Record_Forms
Schema
... create_table "appointment_record_forms", force: :cascade do |t| t.integer "appointment_id", limit: 4 t.integer "record_form_id", limit: 4 t.datetime "created_at", null: false t.datetime "updated_at", null: false t.text "properties", limit: 65535 end
create_table "appointments", force: :cascade do |t| t.string "duration", limit: 255 t.date "appointment_date" t.integer "patient_id", limit: 4 t.integer "doctor_id", limit: 4 t.datetime "created_at", null: false t.datetime "updated_at", null: false end
create_table "record_form_fields", force: :cascade do |t| t.string "name", limit: 255 t.string "field_type", limit: 255 t.boolean "required" t.integer "record_form_id", limit: 4 t.datetime "created_at", null: false t.datetime "updated_at", null: false end
create_table "record_forms", force: :cascade do |t| t.string "name", limit: 255 t.datetime "created_at", null: false t.datetime "updated_at", null: false end ...
Models

def validate_properties record_form.record_form_fields.each do |record_form_field| if record_form_field.required? && properties[record_form_field.name].blank? errors.add record_form_field.name, "must not be blank" end end end end
class RecordForm < ActiveRecord::Base has_many :record_form_fields
has_many :appointment_record_forms, dependent: :destroy has_many :appointments, through: :appointment_record_forms

end
class RecordFormField < ActiveRecord::Base belongs_to :record_form end
Controller
class AppointmentsController < ApplicationController
. . . def appointment_params params.require(:appointment).permit(:duration, :appointment_date, :patient_id, :doctor_id, :record_form_ids, :appointment_form_ids ) end end
View
Appointments/_form.html.erb
... <%= f.fields_for :appointment_record_forms do |builder| %> <%= f.select_tag :record_form_id, options_from_collection_for_select(RecordForm.all, :id, :name) %> <%= render 'appointment_record_form_fields', f: builder %> <% end %> <%= link_to_add_fields "Add Field", f, :appointment_record_forms %> ...
Partial
Appointments/_appointment_record_form_fields.html.br
<%= f.fields_for :properties, OpenStruct.new(@appointment_record_forms.properties) do |builder| %> <% @appointment_record_forms.record_form.record_form_fields.each do |record_form_field| %>
<%= render "appointments/fields/#{record_form_field.field_type}", record_form_field: record_form_field, f: builder %> <% end %> <% end %>
<%= f.hidden_field :_destroy %> <%= link_to "remove", '#', class: "remove_fields" %>
Atualmente ao rodar a aplicação esta com o erro:
undefined method `properties' for :appointment_record_forms:Symbol Gostaria de saber como eu devo fazer no controller do appointment para receber a associação, na view para inserir o formulario dinamico e Partial para listar salvar os registro no hash e mostrar os campos do formulario corretamente.
Desde de já agradeço se alguem poder ajudar.
