Relation#as 将改变 4.0 中的行为。使用 `map_to` 代替

Relation#as will change behavior in 4.0. Use `map_to` instead

在赏花指南中 https://hanamirb.org/guides/1.2/associations/has-many/#usage

当我使用方法时

@book = BookRepository.new.find_with_tickets(params[:id])

我收到一条消息:

我不知道应该用什么代替 'map_to'。

您应该将 #as 替换为 #map_to,它将照常工作。
