有表users和表orders,rails生成的关联表是orders_users,现在可不可以在users_controller.rb中通过User更新orders_users表中的字段值,要怎么操作……

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 = {})
