幫助重構named_scope

Question

我有以下named_scope：

named_scope :commentors, lambda { |*args| 
     { :select => 'users.*, count(*) as total_comments', 
     :joins => :comments, 
     :conditions => { :comments => { :public_comment => 1, :aasm_state => 'posted', :chalkboard_user_id => nil} }, 
     :group => 'users.id', 
     :having => ['count(*) > ?', args.first || 0], 
     :order => 'count(*) desc' } 
     } 

我需要重構的條件如下：

["(public_comment = ? and box IS NOT NULL and can IS NOT NULL and aasm_state != ?", true, 'removed')] 

我並沒有與語法更改條件的運氣。有人可以提供協助嗎？

Answer 1

它看起來像你只需要將表名稱的字段。我不知道哪個表box和can屬於但這應該給你一個想法：

["comments.public_comment = ? and box IS NOT NULL and can IS NOT NULL and comments.aasm_state != ?", true, 'removed')] 

您也有一個開放的括號在我刪除的開始。
