我目前正在使用rails教程的第12步，并且在发送帐户激活电子邮件和访问某些页面时出现问题（我收到错误）
请求密码重置时，我收到以下错误
NameError in PasswordResetsController#create
uninitialized constant User::FILL_IN

def create_reset_digest
self.reset_token = User.new_token

当我尝试查看用户时，我收到以下错误
NameError in UsersController#show
uninitialized constant UsersController::FILL_IN

def new
@user = User.new
end
def create
@user = User.new(user_params)

@user.send_activation_email

redirect_to root_url
else
render 'new'
end
end
def edit
@user = User.find(params[:id])

def update
@user = User.find(params[:id])
if @user.update_attributes(user_params)
flash[:success] = "Profile updated"
redirect_to @user
else

end
end

User.find(params[:id]).destroy
flash[:success] = "User deleted"
redirect_to users_url
end

store_location

end
end
# Confirms the correct user.
def correct_user
@user = User.find(params[:id])
redirect_to(root_url) unless @user == current_user
end
def admin_user
redirect_to(root_url) unless current_user.admin?
end
end
我已经在这里待了一天以上寻找不同帖子的答案，回顾并重做我的步骤，但我不知道我做错了什么。
我无法访问用户页面，当我提交忘记密码时，我收到错误
def index
@users = User. where(activated: true) . paginate(page: params[:page] )
end
def show
@user = User. find(params[:id] )
redirect_to root_url and return unless true
end
def activate
update_columns(activated: true, activated_at: Time.zone.now)
end
它应该是：
update_columns(reset_digest: User.digest(reset_token), reset_sent_at: Time.zone.now)
