我有以下从 Entry 模型继承的 mongoid 模型:
class Entry::Twitter < Entry
field :retweet_count, :type => Integer, :default => 0
field :retweeted, :type => Boolean, :default => false
field :favorited, :type => Boolean, :default => false
# in_reply_to_screen_name, in_reply_to_status_id_str, in_reply_to_user_id_str
field :reply, :type => Hash
field :from, :type => Hash # user: id_str, name, screen_name
field :time, :type => Time # created_at
field :data, :type => Hash # entities (hashtags and user_mentions)
field :assets, :type => Hash # urls from original entities
field :service, :type => String, :default => "twitter"
attr_accessible :assets
# validations
validates_presence_of :retweet_count, :from, :time, :data
# override set_service cause of https://github.com/sferik/twitter/issues/303
def set_service
self.service = "twitter"
end
end
当我尝试引用它时,我收到以下警告:
ruby-1.9.3-p125 :001 > Entry::Twitter
(irb):1: warning: toplevel constant Twitter referenced by Entry::Twitter
=> Twitter
它没有引用我的模型,而是引用了由 gem 定义的顶级常量 Twitter。
我能做些什么来解决这个问题?我不想为我的班级使用另一个名字。
