Ver. 4.0.3 to 4.0.4. Then missing attribute: state

[kntmrkm]

I have a question.

My code summary is...

class Reservation < ActiveRecord::Base
  include AASM
  aasm column: :state, skip_validation_on_save: false, requires_new_transaction: false do
      state :issued, initial: true
      state :accepted
      state :refused

When upgrade version 4.0.3 to 4.0.4.
AASM need a column state?

Case 1.

Reservation.select(:date, :period_list_id).find_by(id: params[:reservation_id])

Above code occured this error.

missing attribute: state

So, I added state column.

Reservation.select(:state, :date, :period_list_id).find_by(id: params[:reservation_id])

It's no errors.

Case 2.

   # At controller. 
   @account.reservations.accepted.group_by_date

    # At model.
    scope :group_by_date, -> do
      select(reservations[:date], reservations[:number].sum.as('sum_number')).
      group(:date)
    end

Above code occured error. missing attribute: state.

but, I can't add column state, because Reservation SQL is grouped.

How Should I fix this code?

I will take a look into this. Just to be clear, it all worked with version 4.0.3?

[kntmrkm]

Yes.
Version 4.0.3 works well.

[alto]

Allright. Then I know what causes this problem. Will fix it today.

Just released version 4.0.5 fixing this bug. Let me know how things work for you.

[kntmrkm]

I tried.
It work well.

Thanks for quick fix!

I got this issue in 4.0.4, but this fix in 4.0.5 also breaks something in our application.
I haven't dug into it, and just want to let you know first.
Will stick with 4.0.3 at the moment, and would try to figure out what's going on when I got time on this.

@godfat Could you create a new ticket, please? And be a little bit more descriptive, what the actual problem is. Cheers!

[godfat]

@alto will do when I got time on digging into it. Thanks!
