func NewMigrator added in v0.0.183 

func NewMigrator(c *pop.Connection, l *logrusx.Logger, tracer *tracing.Tracer, perMigrationTimeout time.Duration) *Migrator

NewMigrator returns a new "blank" migrator. It is recommended to use something like MigrationBox or FileMigrator. A "blank" Migrator should only be used as the basis for a new type of migration system.

func (*Migrator) CreateSchemaMigrations added in v0.0.183

func (m *Migrator) MigrationIsCompatible(dialect string, mi Migration) bool

func (*Migrator) Reset added in v0.0.183 

func (m *Migrator) Reset(ctx context.Context) error

Reset the database by running the down migrations followed by the up migrations.

func (*Migrator) Status added in v0.0.183 

func (m *Migrator) Status(ctx context.Context) (MigrationStatuses, error)

Status prints out the status of applied/pending migrations.

func (*Migrator) Up added in v0.0.183 

func (m *Migrator) Up(ctx context.Context) error

Up runs pending "up" migrations and applies them to the database.

func (*Migrator) UpTo added in v0.0.183 

func (m *Migrator) UpTo(ctx context.Context, step int) (applied int, err error)

UpTo runs up to step "up" migrations and applies them to the database. If step <= 0 all pending migrations are run.

type TestMigrator 

type TestMigrator struct {
	*Migrator
}

TestMigrator is a modified pop.FileMigrator

func NewTestMigrator 

func NewTestMigrator(t *testing.T, c *pop.Connection, migrationPath, testDataPath string, l *logrusx.Logger) *TestMigrator

Returns a new TestMigrator After running each migration it applies it's corresponding testData sql files. They are identified by having the same version (= number in the front of the filename). The filenames are expected to be of the format ([0-9]+).*(_testdata(\.[dbtype])?.sql
