Railsシードの移行がエラーで停止しています。ActiveModel :: UnknownAttributeError

Question

rake db:seed私は通常動作しますが、現在は失敗しています。

ここにエラーとコードがあります。

私のエラーログ：

User.rb：

class User < ApplicationRecord 
cattr_accessor :current_user   
belongs_to :highschool, optional: true 
end 

高校の移行：ユーザーへ

class CreateHighschools < ActiveRecord::Migration[5.0] 
def change 
create_table :highschools do |t| 
    t.string :secondaryschool 

    t.timestamps 
end 
end 
end 

高校の移行参照：

class AddHighschoolRefToUsers < ActiveRecord::Migration[5.0] 
def change 
add_reference :users, :highschools, foreign_key: true 
end 
end 

Highschool.rb：

class Highschool < ApplicationRecord 
has_many :users 
end 

Highschools_controller.rb：

class HighschoolsController < ApplicationController 
before_action :authenticate_user!, only: [:new, :create] 
def create 
    @highschool = Highschool.new(highschool_params) 
    if @highschool.save 
    render json: @highschool 
else 
    render json: {errors: @highschool.errors.full_messages} 
end 
end 
private 
    def highschool_params 
params.require(:highschool).permit(:secondaryschool) 
end 
end 

Schema.rb：

create_table "highschools", force: :cascade do |t| 
t.string "secondaryschool" 
t.datetime "created_at",  null: false 
t.datetime "updated_at",  null: false 
    end 

Seeds.rb：

Highschool.destroy_all 
special = Highschool.create!(Secondaryschool: "Stuyvesant High School") 
special2 = Highschool.create!(Secondaryschool: "Brooklyn Tech") 
special3 = Highschool.create!(Secondaryschool: "Bronx Science") 

Answer 1

は、タイプミスをTheresの。

special = Highschool.create!(secondaryschool: "Stuyvesant High School") 
special2 = Highschool.create!(secondaryschool: "Brooklyn Tech") 
special3 = Highschool.create!(secondaryschool: "Bronx Science")
