Rails Includes with ordering not by ID

Question

I have a simple include statement in my controller but the order for the included table is by default id. In my case I need to order the element in the same way as the uuid is received.

Query:

compare_uuids = {xyz, ytb, tyd}
@books = Book.where(uuid: compare_uuids).includes(:venue, :related_publisher, :related_author) 

The above expression is responding well but say if the uuid ordering with their id are as:

id     uuid
5      xyz
1      ytb
2      tyd

The expressions that make up when the statement run is order by id. So the uuid order is lost. Is there any work around to it.

Answer 1

Just try this...

has_many :books, :order => 'priority DESC'

In rails 4 this is now deprecated, the new approach would be

has_many :books, -> { order(:priority => :desc) }

Get output:

you can try

Authors.books.except(:order).order('priority DESC')
# OR
Authors.books.reorder('priority DESC')
