Question

저는 하나의 테이블 상속과 두 개의 사용자 하위 클래스 인 직원 및 임상의가있는 사용자 모델을 가지고 있습니다. 사용자 테이블에서 nil 열을 피하기 위해 ClinicianProfile 모델과 clinician_profiles 테이블을 만들었습니다. 임상의 이름이 사용자 테이블에 있습니다.

class ClinicianProfile < ApplicationRecord 
    belongs_to :clinician 

class Clinician < User 
    has_one :clinician_profile 

내가 콘솔에서 같은 것을 할 수 있어야한다 보인다 :

ClinicianProfile.last.clinician.name 

을하지만이 나에게 다음과 같은 오류 제공 :

NameError: uninitialized constant ClinicianProfile::Clinician 

나는, 그러나 할 수 있습니다 :

ClinicianProfile.last.clinician_id 

잘못하고있는거야? 왜 사용자 테이블에서 임상의 이름에 액세스 할 수 없습니까?

도움 주셔서 감사합니다.

다음은 스키마입니다

create_table "users", force: :cascade do |t| 
    t.string "name" 
    t.string "email" 
    t.datetime "created_at",      null: false 
    t.datetime "updated_at",      null: false 
    t.string "password_digest" 
    t.string "remember_digest" 
    t.string "activation_digest" 
    t.boolean "activated",   default: false 
    t.datetime "activated_at" 
    t.string "reset_digest" 
    t.datetime "reset_sent_at" 
    t.integer "university_id" 
    t.integer "role" 
    t.index ["email"], name: "index_users_on_email", unique: true 
    end 

    create_table "clinician_profiles", force: :cascade do |t| 
    t.datetime "created_at",   null: false 
    t.datetime "updated_at",   null: false 
    t.string "firstname" 
    t.string "lastname" 
    t.string "address1" 
    t.string "address2" 
    t.string "city" 
    t.string "state" 
    t.string "zip" 
    t.boolean "accepting_patients" 
    t.integer "rate" 
    t.string "license_number" 
    t.string "license_state" 
    t.string "school" 
    t.integer "year_graduated" 
    t.boolean "accepts_insurance" 
    t.boolean "sliding_scale" 
    t.text  "bio" 
    t.boolean "verified" 
    t.integer "years_licensed" 
    t.integer "years_of_experience" 
    t.integer "clinician_id" 
    t.integer "years_practicing" 
    t.string "website" 
    end

죄송하지만,이 코드에 대한 수정없이 겉으로는 해결.
