Method Run

core/migrations_runner.go:42–117

Run interactively executes the current runner with the provided args. The following commands are supported: - up - applies all migrations - down [n] - reverts the last n (default 1) applied migrations - history-sync - syncs the migrations table with the runner's migrations list

(args ...string)

// - down [n]     - reverts the last n (default 1) applied migrations
// - history-sync - syncs the migrations table with the runner's migrations list
