Vanilla Rails Data Modeling

Database schema conventions from production 37signals patterns.

For state-as-records pattern details, see vanilla-rails-models.

UUID Primary Keys

All tables use UUIDs. No auto-incrementing integers.

create_table :cards, id: :uuid do |t|
  t.uuid :account_id, null: false
  t.string :title
  t.timestamps
end

UUIDv7 (timestamp-ordered), base36 encoded as 25-character strings. No ID enumeration, merge-safe, no sequence contention.
