postgresql sequence and migrations

Lance wrote in post #93083:

There is a method in the Postgresql adapter called reset_pk_sequence. I
haven't used it yet but it sounds like this is what you are looking for.

I used it:

Account.delete_all
Account.reset_pk_sequence

but, it didn't work. The next Account.save had the :id = last :id + 1

At least it didn't crash :slight_smile:

I'm still looking for a solution.

Here is the solution:

Account.delete_all
Account.connection.execute "ALTER SEQUENCE accounts_id_seq RESTART WITH
1"

Hope this helps
