Description
Having a model as part of an application called: front_booking:
class AccomodationUnit(Model):
Facility = ManyToManyField(Facility, verbose_name = 'faciliteiten')
Generates an "Identifier name is too long" exception when doing a syncdb on mysql 5.0.x. Mysql is only able to store identifiers of 64 bytes max.
_mysql_exceptions.OperationalError: (1059, "Identifier name 'AccomodationUnit_id_referencing_front_booking_accomodationunit_id' is too long")
Possible solution would be to allow a user to somehow influence the naming of these identifiers or use identifier names of 64 bytes max. in size
