重命名外键后出现未知属性错误

我有三个用户角色:

  enum role: { staff: 0, clinician: 1, admin: 2 }

我在patients表中有一个user\u id列,用于存储创建病历的员工用户的id。为了提高名称的清晰度,我将列从user\u id重命名为author\u id,并调整了关系,我知道如何将更改引用到外键。

当我尝试访问/patients/new时,会出现错误:

unknown attribute 'user_id' for Patient.

这个错误特别突出了我的新患者方法中的这一行:

@patient = current_user.patients.build

我做错了什么?谢谢你的帮助!

患者表:

 create_table "patients", force: :cascade do |t|
        t.datetime "created_at",         null: false
        t.datetime "updated_at",         null: false
        t.integer  "age"
        t.integer  "staff_clinician_id"
        t.integer  "author_id"
        t.index ["author_id"], name: "index_patients_on_author_id"
        t.index ["staff_clinician_id"], name: "index_patients_on_staff_clinician_id"
      end

患者模型

class Patient < ApplicationRecord
  belongs_to :user, -> { where role: :staff }, foreign_key: 'author_id'

员工用户问题

require 'active_support/concern'

module StaffUser
  extend ActiveSupport::Concern

  included do
    belongs_to :university
    has_many :patients
    has_many :referral_requests
    validates :university_id, presence: true, if: :staff?
  end

  class_methods do
  end
end

这是我的患者控制器:

class PatientsController < ApplicationController
    before_action :require_login

def new
    @patient = current_user.patients.build
end

def index
    authorize Patient
    @patients = policy_scope(Patient)
end

def show
    @patient = Patient.find(params[:id])
end

def edit
    @patient = Patient.find(params[:id])
end

def update
    @patients = Patient.all
    @patient = Patient.find(params[:id])
    if @patient.update_attributes(patient_params)
        flash[:success] = "Patient Updated!"
        render 'patients/index'
    else
        render "edit"
    end
end


def create
    @patient = current_user.patients.build(patient_params)
    if @patient.save
        flash[:success] = "Patient Created!"
        redirect_to new_referral_request_path(patient_id: @patient.id)
    else
        Rails.logger.info(@patient.errors.inspect)
        render 'patients/new'
end
end


private

def patient_params
    params.require(:patient).permit(:age, :staff_clinician_id, :author_id, insurance_ids: [], gender_ids: [], concern_ids: [], race_ids: [])

end
end
