Sometimes group_by_date results are not sorted

[thebravoman]

This is the exact code

          render json: [
            { name: :assignments, data: assignments.group_by_day(:created_at).count },
            { name: :assignment_visits, data: assignment_visits.group_by_day(:created_at).count },
            { name: :messages, data: messages.group_by_day(:created_at).count },
            { name: :telegram_chats, data: telegram_chat_records.group_by_day(:created_at).count }
          ]

and this is the result

Sometimes the results are not sorted by date and I don't understand why.
I think it is only here where the json is an array of data.

Hi @thebravoman, JSON objects are unordered, so you'll need to convert them to arrays with to_a if you want to preserve the order.

The getting started says another thing @ankane
https://github.com/ankane/groupdate?tab=readme-ov-file#getting-started

Results are returned in ascending order by default, so no need to sort.

Am I missing something?

The problem is not that the json is not sorted but that the

assignments.group_by_day(:created_at).count 

returns something that is not sorted and the getting started says there is no need to sort.

If you can create a minimal reproducible example or test case that shows this, happy to look into it more.
