Rails 3 ActiveRecord问题

Question

我对你有几个问题Rails 3大师在那里。你如何完成以下任务？

以下伪代码当前无效。谢谢大家。

@items = (@itemsA + @itemsB).order("name ASC") 

@item = Item.where("type = ?" and "condition = ?", "book", "new") 

@commenteditems = Item.find_all_by_type_and_condition("book", "new").include("notes").select("item[name]", "notes[note]") 

@selecteditems = @items.where("select = ?", true) 

Answer 1

我相信你要找的是scopes。
