TODO:

  • Migration action sorting procedure need some fixes. When many foreign keys in tables, there is a bug with action order. Now, please check it manually (--preview option)

  • Downgrade is not supported, add it
  • This module tested with postgresql (I use it with my projects). Test with mysql and sqlite.
