How can I set specific constraints to the fields of a db table with peewee?

I need to set specific constraints to the fields of a db table, particularly:

  • the field can only contain alphanumeric ascii characters, underscores, and dashes
  • the field cannot start with an underscore or dash
  • the field must be between 4 and 64 characters long

I looked at peewee docs but didn't find anything (except how to set max length).

Any help is much appreciated, thanks!
