Rails reorder isn't working? -

-

i have feedback model 2 other models (comment , review) inherit from.

i have default scope in feedback model orders id asc

i've added scope feedback model:

class feedback < activerecord::base   include paginatable    belongs_to :video    default_scope     order(:id => :asc)   end    scope :newest, -> { reorder(:created_at => :desc) }  end

i have video model has:

has_many :feedback  has_many :latest_feedback, -> { newest }, class_name: 'feedback'

the problem i'm having when call

video.includes(:latest_feedback).find(1)

it still orders feedback id first , created_at not want. want latest_feedback ordered created_at

here's does:

video load (0.3ms)  select  `videos`.* `videos`  `videos`.`id` = 85  order `videos`.`id` desc limit 1 feedback load (0.6ms)  select `feedback`.* `feedback`  `feedback`.`video_id` in (1)  order `feedback`.`id` asc, `feedback`.`created_at` desc

here's need do:

video load (0.3ms)  select  `videos`.* `videos`  `videos`.`id` = 85  order `videos`.`id` desc limit 1 feedback load (0.6ms)  select `feedback`.* `feedback`  `feedback`.`video_id` in (1)  order `feedback`.`created_at` desc

update

i guess known issue rails. there still open pull request fix here:

https://github.com/rails/rails/pull/16531

it doesn't land until rails 5.0.0 though.

you can use video.joins(:latest_feedback).find(1). seems rails appends default scope without scope recalculation on includes
