Rails 3查询多维数组

I have an array called @venues with all the restaurants within a radius. Each venue has_manydishes and I want to insert an array of these dishes into venue.

我有一个名为@venue的数组，所有餐厅都在一个半径内。每个场馆都有很多菜色，我想把这些菜色加入到场馆中。

@venues = Venue.within(radius, :origin => [lat, lng]).order('distance ASC')

@venues.each do |venue|
  dishes = venue.dishes.where("? BETWEEN DATE(served_from) AND DATE(served_until)", Date.today)
  # insert dishes into venue
end

How do I insert dishes into venue so that I can access all the available dishes of an venue with: @venues[i].dishes?

如何将菜肴插入场地，以便我可以使用@venues[I].dishes?

It might might more sense to add a scope on Dish itself:

在菜肴本身增加一个范围也许更有意义:

scope :today, :conditions => ["? BETWEEN DATE(served_from) AND DATE(served_until)", Date.today]

With that, you can access the available dishes with @venues[i].dishes.today

有了它，你就可以通过@venues[i].dish .today来获取可用的菜肴了
