Question

我从Rails 3.x迁移到Rails 4.2

我有以下代码：

Order.all :conditions => ["flagged = ? AND orders_id != ? AND (
  delivery_name = ? OR
  delivery_telephone = ? OR
  email = ? OR
  ((delivery_address IS NOT NULL AND delivery_address != '') AND delivery_address = ?) OR
  (remote_ip IS NOT NULL AND remote_ip = ?)
  )",
  true,
  self.orders_id,
  self.delivery_name,
  self.delivery_telephone,
  self.email,
  self.delivery_address,
  self.remote_ip,
]

当我运行测试时，我得到以下的修复：

DEPRECATION WARNING：不推荐使用Relation＃all。如果你想急切加载关系，你可以调用#load（例如Post.where(published: true).load）。如果要从关系中获取记录数组，一个＆GT;你可以拨打#to_a（例如Post.where(published: true).to_a）。（称为来自similar_flagged_orders at /Users/fisnik/code/myr-admin/app/models/order.rb:173）

有什么建议吗？

Answer 1

Order.where("flagged = ? AND orders_id != ? AND (
  delivery_name = ? OR
  delivery_telephone = ? OR
  email = ? OR
  ((delivery_address IS NOT NULL AND delivery_address != '') AND delivery_address = ?) OR
  (remote_ip IS NOT NULL AND remote_ip = ?)
  )",
  true,
  orders_id,
  delivery_name,
  delivery_telephone,
  email,
  delivery_address,
  remote_ip
)

从3.x直接升级到4.2是疯狂的，你不可避免地要努力使事情发挥作用。

Do it gradually

首先升级到3.2，然后升级到4.0，只有这里有2个选项 - 4.1和4.2。

逐步升级您的测试框架。

迁移到RAILS 4.2
