DB modifications may occur during team development! !! If you update it easily, the server may go wrong. ?? ?? Annoying the team: confounded: I was afraid to update it too, but if I followed the steps below, it worked fine: relaxed:
$rake db:drop
#Delete all DB information! !! Registered user information will also be deleted!
$rake db:create
#DB update
$rake db:migrate
#My Great
$rake db:migrate:status
#Make sure you have properly migrated
By the way, ... If you have created categories etc. in a text editor, please do it after migrating the code below as well! !!
$rake db:seed
This will update the DB OK: laughing: This method also deletes the registered user information, so you need to register again!
