    关联两张表时,会有生成以下的方法,更新orders_users也是通过以下方法操作

    user.orders<<(object, ...)
    user.orders.delete(object, ...)
    user.orders.destroy(object, ...)
    user.orders=objects
    user.orders_singular_ids
    user.orders_singular_ids=ids
    user.orders.clear
    user.orders.empty?
    user.orders.size
    user.orders.find(...)
    user.orders.where(...)
    user.orders.exists?(...)
    user.orders.build(attributes = {})
    user.orders.create(attributes = {})
    user.orders.create!(attributes = {})
