我的代码：
@H_301_2@class User < ActiveRecord::Base
belongs_to :university
end
class University < ActiveRecord::Base
has_many :users,dependent: :destroy
end
和我的模型User有一个university_id属性.
如果我做了University.find(1).users我得到了用户列表,但如果我做了User.find(1).university(我检查过university_id不是零)我得到：
@H_301_2@NoMethodError: undefined method `university' for #<User:0x00000003859fc8> from /home/mari/.rvm/gems/ruby-1.9.2-p290/gems/activemodel-3.0.10/lib/active_model/attribute_methods.rb :392:in `method_missing' from /home/mari/.rvm/gems/ruby-1.9.2-p290/gems/activerecord-3.0.10/lib/active_record/attribute_methods. rb:46:in `method_missing' from (irb):14 from /home/mari/.rvm/gems/ruby-1.9.2-p290/gems/railties-3.0.10/lib/rails/commands/console.rb:44:in`start' from /home/mari/.rvm/gems/ruby-1.9.2-p290/gems/railties-3.0.10/lib/rails/commands/console.rb:8:in start' from /home/mari/.rvm/gems/ruby-1.9.2-p290/gems/railties-3.0.10/lib/rails/commands.rb:23:in `<top (required)>' from script/rails:6:in `require' from script/rails:6:in `<main>'我究竟做错了什么？我有另一个模型,他们工作得很好.有什么建议？提前致谢
