getMigration :: (MonadBaseControl IO m, MonadIO m) => Migration (SqlPersist m) -> SqlPersist m [Sql]Source

runMigrationSilent :: (MonadBaseControl IO m, MonadIO m) => Migration (SqlPersist m) -> SqlPersist m [Text]Source
Same as runMigration, but returns a list of the SQL commands executed
instead of printing them to stderr.
runMigrationUnsafe :: (MonadBaseControl IO m, MonadIO m) => Migration (SqlPersist m) -> SqlPersist m ()Source
migrate :: (MonadIO m, MonadBaseControl IO m, PersistEntity val) => [EntityDef] -> val -> Migration (SqlPersist m)Source
commit :: MonadIO m => SqlPersist m ()Source
Perform a database commit.
rollback :: MonadIO m => SqlPersist m ()Source
Perform a database rollback.
