Rails-Belongs_to 在同一个表中
我有一个用户表，每个用户都有另一个用户，他们必须“杀死”关联，如下所示。
class User < ActiveRecord::Base
belongs_to(:user_to_kill, :class_name => :User)
但是，当我进行以下调用时：
@current_user.user_to_kill.screen_name
它返回以下错误和堆栈跟踪
NameError: uninitialized constant User::User
/app/.bundle/gems/ruby/1.9.1/gems/activerecord-3.0.3/lib/active_record/base.rb:1199:in `compute_type'
/app/.bundle/gems/ruby/1.9.1/gems/activerecord-3.0.3/lib/active_record/reflection.rb:162:in `klass'
/app/.bundle/gems/ruby/1.9.1/gems/activerecord-3.0.3/lib/active_record/associations/belongs_to_association.rb:59:in `find_target'
/app/.bundle/gems/ruby/1.9.1/gems/activerecord-3.0.3/lib/active_record/associations/association_proxy.rb:237:in `load_target'
提前感谢您的帮助。
