我正在为我的收件箱消息系统处理未读文件夹。我在转到 /users/1/messages?mailbox=unread 时收到了一个未定义的方法“unread_messages”，它指向消息控制器。但是我在 user.rb 中定义了 unread_messages 以便它在收件箱中显示未读消息，所以我假设代码也应该适用于未读文件夹。任何帮助，将不胜感激。
用户.rb：
class User < ActiveRecord::Base
has_secure_password
attr_accessible :role, :age, :age_end, :password_confirmation, :about_me, :feet, :inches, :password, :birthday, :career, :children, :education, :email, :ethnicity, :gender, :height, :name, :password_digest, :politics, :religion, :sexuality, :user_drink, :user_smoke, :username, :zip_code

validates_format_of :email, with: /^[-a-z0-9_+\.]+\@([-a-z0-9]+\.)+[a-z0-9]{2,4}$/i

has_many :galleries
has_many :photos, :through => :galleries
before_create { generate_token(:auth_token) }
ROLES = %w[admin user guest banned]
# models/user.rb
after_create :setup_gallery
def received_messages
Message.received_by(self)
end
def unread_messages?
unread_message_count > 0 ? true : false
end
def sent_messages
Message.sent_by(self)
end
# Returns the number of unread messages for this user
def unread_message_count
eval 'messages.count(:conditions => ["recipient_id = ? AND read_at IS NULL", self.user_id])'
end

role.present? && role.to_sym == role_name.to_sym
