There is a migration written through safeUp()/safeDown().
Made a migration, decided to roll back
public function safeDown()
It was an error due to FK(my joint), as a result, there were 2 tables left in the database(category and post).
And if I'm not mistaken(maybe it was before, but it seems to be not) in the migration table an entry m000000_000000_base appeared with the date 1456394833(February 25)
What have I done wrong? Or what is the problem with the transaction?
