我一直在嘗試將布林值添加到 Ruby on Rails 應用程式以進行輔導。我一直遇到以下錯誤：錯誤訊息
NoMethodError in TutorsController#create undefined method `supert=' for #Tutor:0x00007fa5593f99f8 你的意思是？超級=超級超級超級？
我已采取與創建變數“學院”相同的步驟，并且沒有問題。
導師控制器.rb
class TutorsController < ApplicationController

@tutor_person = TutorPerson.new
@person = Person.new
@tutor = Tutor.new

def tutor_params
params.require(:tutor_person).permit(:id_num, :grade, :name, :email, :password, :password_confirmation, :adminKey, :academy, :supert)
end
def tutor_person
TutorPerson.new(tutor_params)
end
end
導師人.rb
class TutorPerson
include ActiveModel::Model
attr_accessor :name, :email, :password, :password_confirmation, :grade, :id_num, :adminKey, :academy, :supert
def self.from_tutor_id(id)
tutor = Tutor.find(id)
person = Person.find(tutor.people_id)
new(name: person.name, email: person.email, grade: tutor.grade, id_num: tutor.id_num)
end
end
幾天來我一直在努力解決這個問題，所以任何提示/指標將不勝感激！
謝謝！

uj5u.com熱心網友回復：
似乎您希望您的Tutor類有一個屬性supert，但supert在TutorPersonnot in 中定義Tutor。
這就是為什么你得到一個NoMethodError.
