hello, i have this crazy label for each time i create a migration that use the time instead of a integer. it makes things very hard to switch between the version of the database that you want to use. i also have this crazy ID for each object that i create :
How can set up rails to have easy version and id numbers.
thank you
The number is timestamp. Really useful when you have several collaboration in same project.
If you want the old system us that in your environement.rb file
config.active_record.timestamped_migrations = false
Why would you need to switch between "versions of the database"? If you mean redoing and undoing a migration, you can do it like this:
rake db:rollback
Which undoes the last migration, then
rake db:migrate
To redo it again. You shouldn't need anything else, since migrations should always be done sequentially in the timestamped order.
