Is there a way to reset only a part of the DB in Rails?

原文 2015-08-13 11:40:45 7 1 ruby-on-rails

I was wondering if it's possible to reset just a part of the DB to free up the IDs that were taken by previous entries. For example, let's say your DB is filled with info about users and about admins . Then I'd like to delete all admins or users and get back to filling the DB up back from ID 1 depending on which ones I've removed. Is this even possible without doing rake db:reset and resetting the whole DB ?

Just delete the records first. Then you have to look for the DBspecific command that resets the autoincrement counter. This post shows how to do that (they do it in a migration although I think the rails console would work as well:
