Hi Everyone, Do I edit the corresponding migration also to show the belongs_to (and the has_many)? I have a many to many relationship where I am using the "has_many :through" association.

Imagine a rails app that has two versions that developers need to support: 1.0 and 2.0. There are 2 database schemas: app-1, app-2. After fixing a bunch of very important bugs in production (1.0), some junior developer named Bob switches the branch to 2.0 to implement a few features but somehow gets his app connected to the schema app-1 and does rake db:migrate As I understand, in that case

When I do a migration, the changes are make in the test database. Does anyone know the reason? In the config/environment.rb file, I have this: ENV[''RAILS_ENV''] ||= ''production'' And in the db/ folder, it creates a file named test.sqlite3 When I did the migrations, RoR used the test database, but when I want to make something in the application, the migrations

Hi all, I'm using ZFS on Linux block volumes as my VM storage and want to do live migrations between hypervisors. If I create ZFS snapshot of used volume on source host, send it do destination host (zfs send/recv) and then run live migration with VIR_MIGRATE_NON_SHARED_DISK flag, the migration works OK.
