Change starting id number

Question

I have an \'Account\' model in Rails with its corresponding \'accounts\' table in the database. If I wipe the database and start over, the \'account_id\' field will always star

Answer 1

A pure Ruby, database-independent approach could be:

class MyModel
  before_create do
    self.id = [1000, (self.class.maximum(:id) || 0) + 1].max if self.id.nil?
  end
end

When you're creating lots of records at once, this may not perform so well though.
