Peewee - Database Errors



Python’s DB-API standard (recommended by PEP 249) specifies the types of Exception classes to be defined by any DB-API compliant module (such as pymysql, pyscopg2, etc.).

Peewee API provides easy-to-use wrappers for these exceptions. PeeweeException is the base classes from which following Exception classes has been defined in Peewee API −

  • DatabaseError

  • DataError

  • IntegrityError

  • InterfaceError

  • InternalError

  • NotSupportedError

  • OperationalError

  • ProgrammingError

Instead of DB-API specific exceptions to be tried, we can implement above ones from Peewee.
