Comment (by Michael Kany):
Ich habe gesehen, das es anstelle der vorgeschlagenene zwei neuen Field
classes ('IdentityAutoField': 'integer', 'IdentityBigAutoField':
'bigint',)
Ist es möglich die AutoField-klasse so zu erweitern
Zum beispiel mit:
class AutoField(Field):
...
generated_identity = False # für die unterscheidung serial oder generated
generated_by_default = False # für GENERATED ALWAYS wenn False/ GENERATED
BY DEFAULT wenn True
seq_opt_start_with = 1
seq_opt_increment_by = 1
def __init__(self, generated_identity = False, generated_by_default =
False, seq_opt_start_with = 1, seq_opt_increment_by = 1, **kwargs):
...
Da ist auch ein anderes Ticket
#56 Primary key columns should be UNSIGNED
das mit den Parametern
seq_opt_start_with = 1
seq_opt_increment_by = 1
gegebenenfalls passen würde. Test ob seq_opt_start_with >= 0
