我有3個模型商店部分和價格,部分有shop_id和價格有section_id 我如何顯示商店視圖中的價格?
控制器/ shop_controller.rb操作數應包含1列紅寶石在軌道上
...
def show
@metod_one = Magazine.find(params[:id])
@method_two = Section.find(:all, :conditions => ['shop_id = ?', @method_one])
@method_three = Price.find(:id, :conditions => ['section_id = ?', @method_two])
end
...
該方法不工作 Mysql的::錯誤:操作數應含有1個柱(一個或多個):SELECT * FROM prices
WHERE(prices
id
=「---: ID \ n」和(SECTION_ID = 5480,5482,5483,5485))
TNKS,但不適合我工作10找不到Price with ID = id AND(section_id in(4341,4342,4343)) – Andrew
我改變了:id on:all和this work,thx – Andrew
