新しい予定を作成しようとすると問題が発生します。しかし、最初に私のモデルを見てください

class Patient < ActiveRecord::Base
  attr_accessible :address1, :address2, :city, :comment, :email, :first_name, :init_date,    :init_time, :last_name, :mobile, :notes, :phone, :state, :zip
  before_validation :upcase_patient
  before_save { self.email.downcase! }
  has_many :appointments, dependent: :destroy
  has_many :procedures, through: :appointments

class Procedure < ActiveRecord::Base
  attr_accessible :comment, :occurence, :procedure, :procedure_code, :procedure_price, :procedure_time, :visits
  before_validation :uppercase_procedure
  has_many :appointments
  has_many :patients, through: :appointments

class Appointment < ActiveRecord::Base
  attr_accessible :appointment_date, :appointment_notes, :appointment_time, :procedure_id
  belongs_to :patient
  belongs_to :procedure

class AppointmentsController < ApplicationController
include PatientsHelper
before_filter :signed_in_user

def create
    @patient = current_patient
    @appointment = @patient.appointments.build(params[:appointment])
    if @appointment.save
        flash[:success] = "Appointment scheduled!"
        redirect_to patient_path(@patient)
    else
        render patient_path(@patient)
    end
end

module PatientsHelper

    def current_patient=(patient)
            @current_patient = patient
    end

    def current_patient
            @current_patient
    end

    def current_patient?(patient)
            patient == current_patient
    end
end

current_patientの定義に役立つ「PatientsHelper」を含むこれらのアイテムは、関連付けを構成します。私はpatients_controller内でフォームを正常に作成しました

class PatientsController < ApplicationController
before_filter :signed_in_user
before_filter :admin_user, only: [:destroy]
def show
    @patient = Patient.find(params[:id])
    @procedures = Procedure.all
    @appointments = @patient.appointments.paginate(page: params[:page])
    @appointment = @patient.appointments.build
end

患者のリソースを使用して、新しい予定を作成したいと思います。ここが私が汚されているところです。rspecを介して次のエラーを引き続き受け取ります。

NoMethodError:
   undefined method `appointments' for nil:NilClass

どこが間違っているのですか？どんな助けでも大歓迎です。説明が必要な場合は、次のことを行います。

a_アソシエイト

患者モデル->has_many[：appointments、：procedures（through：appointments）]

プロシージャモデル->has_many[：appointments、：patients（through：appointments）]

予定モデル->belongs_to[：patients、：procedures]

b_予約モデル専用の新しいコントローラーを作成するのではなく、患者コントローラーを介して新しい：appointmentsを作成します

私の間違い！これがスペックテストです。

require 'spec_helper'

describe "Appointment Pages" do
    subject { page }

    let(:user) { FactoryGirl.create(:user) }
    let(:patient) { FactoryGirl.create(:patient) }
    let(:procedure) { FactoryGirl.create(:procedure) } 
    before { sign_in user }

    describe "appointment creation" do
  before { visit patient_path(patient) }

  describe "with invalid information" do

    it "should not create an appointment" do
        expect { click_button "Schedule procedure" }.not_to change(Appointment,
                                                                                                                             :count)
    end

    describe "error messages" do
        before { click_button "Schedule procedure" }
        it { should have_content('error') }
    end
end

describe "with valid information" do
    before do
      procedure_id = procedure.id
      patient_id = patient.id
      fill_in 'appointment_appointment_date', with: "2013-04-04"
      fill_in 'appointment_appointment_time', with: "12:45:00"
      fill_in 'appointment_appointment_notes', with: "Test the notes"
    end
    it "should create a micropost" do
        expect { click_button "Schedule procedure" }.to change(Appointment, 
                                                                                                                    :count).by(1)
      end
    end
  end
end

正確には私が探していたものではありませんが、この回避策を作成しました。

以下を使用すると、それに応じて保存することができました。URLから患者をプルできない理由をまだ見つけることができません-例はapp.dev/patients/2です-ここで患者情報はid2をプルしています...しかし今は何を使用して予定を保存することができますかなり大雑把な方法だと思います。

  1. フォームに、適切なpatient_idをプルする非表示フィールドを追加しました
  2. Appointmentsコントローラーで、attr_accessible：patient_idに追加されました

  3. アポイントメント_コントローラーで 

    def create
@appointment = Appointment.new(params[:appointment])
@current_patient = @appointment.patient_id
if @appointment.save
    flash[:success] = "Appointment scheduled!"
    redirect_to patient_path(@current_patient)
else
    render 'patients/show'
end
end

render 'patients/show'壊れたままですが、別のスレッドに残します。皆様のご協力とご指導に感謝申し上げます。
