这种使用条件是输出我在控制台中看到,当我尝试无法在轨控制台
User.find(2).all_follows
我想要得到的行,其中的followable_type:“Conferece”。
我想这
User.find(2).all_follows.find(:conditions => ["followable_type = ?", "Conference"])
和
User.find(2).all_follows.where(:all, :conditions => ["followable_type = ?", "Conference"])
当我用在哪里,它说没有这样的功能。但是,当我打字,我得到以下输出
User.find(2).all_follows.where
2).all_follows.where 2).all_follows.where_sql
2).all_follows.where_values= 2).all_follows.wheres
2).all_follows.where_clauses 2).all_follows.where_values
2).all_follows.where_values_hash 2).all_follows.wheres=
什么是all_follows? –
它将返回用户所关注的所有人员和会议。我正在使用这个函数,因为我已经使用了act_as_followable gem – Aravind
我可以看到,但它是一个范围(或返回范围的东西)或数组? –
