DBType string // Runner function to run/execute the migration Runner func(Migration, *pop.Connection, *pop.Tx) error }
Migration handles the data for a given database migration
type MigrationBox ¶ added in v0.0.190
MigrationBox is a embed migration box.
func NewMigrationBox ¶ added in v0.0.190
func NewMigrationBox(dir fs.FS, m *Migrator, opts ...func(*MigrationBox) *MigrationBox) (*MigrationBox, error)
NewMigrationBox from a packr.Dir and a Connection.
migrations, err := NewMigrationBox(pkger.Dir("/migrations"))

func (m MigrationStatuses) Table() [][]string
type Migrations ¶ added in v0.0.185
type Migrations []Migration
Migrations is a collection of Migration
func (Migrations) Len ¶ added in v0.0.185
func (mfs Migrations) Len() int
func (Migrations) Less ¶ added in v0.0.185
func (mfs Migrations) Less(i, j int) bool
func (Migrations) SortAndFilter ¶ added in v0.0.201
func (mfs Migrations) SortAndFilter(dialect string, modifiers ...func(sort.Interface) sort.Interface) Migrations
func (Migrations) Swap ¶ added in v0.0.185
func (mfs Migrations) Swap(i, j int)
type Migrator ¶ added in v0.0.183
type Migrator struct { Connection *pop.Connection Migrations map[string]Migrations PerMigrationTimeout time.Duration // DumpMigrations if true will dump the migrations to a file called schema.sql DumpMigrations bool // contains filtered or unexported fields }
Migrator forms the basis of all migrations systems. It does the actual heavy lifting of running migrations. When building a new migration system, you should embed this type into your migrator.
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
CreateSchemaMigrations sets up a table to track migrations. This is an idempotent operation.
func (*Migrator) Down ¶ added in v0.0.183
Down runs pending "down" migrations and rolls back the database by the specified number of steps.
func (*Migrator) DumpMigrationSchema ¶ added in v0.0.183
DumpMigrationSchema will generate a file of the current database schema
func (*Migrator) MigrationIsCompatible ¶ added in v0.0.185
MigrationIsCompatible returns true if the migration is compatible with the current database.
func (*Migrator) Reset ¶ added in v0.0.183
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.
type TestMigrator ¶
type TestMigrator struct {
*Migrator
}
TestMigrator is a modified pop.FileMigrator
func NewTestMigrator ¶
func NewTestMigrator(t *testing.T, c *pop.Connection, migrations, testData fs.FS, 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
