Exceptions hierarchy

class fantastico.exceptions.FantasticoError(msg=None, http_code=400)

FantasticoError is the base of all exceptions raised within fantastico framework. It describe common attributes that each concrete fantastico exception must provide. By default all fantastico exceptions inherit FantasticoError exception. We do this because each raised unhandled FantasticoError is map to a specific exception response.
