在保持初始排序的同时对记录数组进行两次排序
Sorting record array twice while maintaining initial sort
所以我对我的公司有以下查询
companies.where(industry: industries_queried)
我想对它们进行排序，以便返回的第一条记录是 plan_id == 3，然后是 2，然后是 1。（降序）
不过，我也想把这 4 个部分都排列好，让它们按名字的字母顺序排列。
我将如何在 Rails 5 中执行此操作？

4 Ordering
To retrieve records from the database in a specific order, you can use
the order method.
For example, if you're getting a set of records and want to order them
in ascending order by the created_at field in your table:
Customer.order(:created_at)
# OR
Customer.order("created_at")
You could specify ASC or DESC as well:
Customer.order(created_at: :desc)
# OR
Customer.order(created_at: :asc)
# OR
Customer.order("created_at DESC")
# OR
Customer.order("created_at ASC")
Or ordering by multiple fields:
Customer.order(orders_count: :asc, created_at: :desc)
# OR
Customer.order(:orders_count, created_at: :desc)
# OR
Customer.order("orders_count ASC, created_at DESC")
# OR
Customer.order("orders_count ASC", "created_at DESC")
将此应用于您的问题，您最终会得到：
companies.where(industry: industries_queried).order(plan_id: :desc, name: :asc)
