How to reset auto increment field in a ActiveRecord migration?

Question

In my migration I have:

def up
   MyModel.destroy_all
   MyModel.create!({:id=>1,:name=>\'foo\'})
   MyModel.create!({:id=>2,:name=>\'fooBar\'})
   M

In case anyone else wonders how to do this with MYSQL: here is the code one would use in the migration in order to reset the auto increment for a table:

ActiveRecord::Base.connection.execute('ALTER TABLE foo_bars AUTO_INCREMENT = 1')

• Where foo_bars would be the table name whose auto_increment you are resetting.

I figured this out thanks to the answer for this question.
