試したこと

11章のテスト前のコードを書き直しましたがエラー解消されません。

補足情報（FW/ツールのバージョンなど）

使っているのはRails 6.0.3です。
下記に今回変更したコードを貼ります。

class AccountActivationsController < ApplicationController
def edit
user = User.find_by(email: params[:email])
if user && !user.activated? && user.authenticated?(:activation, params[:id])
user.activate
log_in user
flash[:success] = "Account activated!"
redirect_to user
else
flash[:danger] = "Invalid activation link"
redirect_to root_url
end
end
end

class UsersController < ApplicationController
before_action :logged_in_user, only: [:index, :edit, :update, :destroy]
before_action :correct_user, only: [:edit, :update]
before_action :admin_user, only: :destroy

def index
@users = User.paginate(page: params[:page])
end

def show
@user = User.find(params[:id])
end

def new
@user = User.new
end

def create
@user = User.new(user_params)
if @user.save
@user.send_activation_email
flash[:info] = "Please check your email to activate your account."
redirect_to root_url
else
render 'new'
end
end

def edit
@user = User.find(params[:id])
end

def update
@user = User.find(params[:id])
if @user.update(user_params)
# 更新に成功した場合を扱う。
flash[:success] = "Profile updated"
redirect_to @user
else
render 'edit'
end
end
