Hi,
I have a Model Class which has the Below schema:
class Pvt_ip_pools(AtlasAuditModel, AtlasBaseHelper):
"""
Represents a private IP Address used for LB Model.
This inherits all the fields from IPAddress model(database table).
"""
# Each data center has its own IP address range
data_center = models.ForeignKey(DataCenter,
verbose_name="Data Center")
ip = models.GenericIPAddressField(verbose_name="PvtIP",
blank=False,
null=False,
unique=True)
prefix_length = models.PositiveSmallIntegerField(blank=False,
null=False,
unique=False)
gateway = models.GenericIPAddressField(blank=False,
null=False,
unique=False)
* server_interface =
models.ForeignKey('ServerInterface',
related_name='pvt_ip_pools',
blank=True,
null=True,
default=None,
on_delete=models.SET_NULL)*
ipv6 = models.BooleanField(default=0)
segment_id = models.IntegerField(default=0,
verbose_name="Segment_ID")
* ip_status =
models.ForeignKey('IPStatus',
default=None,
null=True, on_delete=models.CASCADE)*
class Meta:
verbose_name = "[LB]Private IP Address"
verbose_name_plural = "[LB]Private IP Addresses"
In this, When a ServerInterface is Deleted, which is a foriegn Key, the
Model here, sets the attribute to NULL.
But, each of these will have a Object "IP_STATUS" which will have a value
assigned ( FREE, USED ..)
*Now On Delete of the ServerInterface Object, How do i reset the Value of
"IP_STATUS" to FREE everytime Server_interface object is deleted?*
Another Problem observed is that When The ServerINterface Object is deleted
from ADMIN page, offcourse, it will not call the default delete.
Even in this case
*, how do i reset the value of IP_STATUS? when Object deleted from ADMIN
Page.*
Any Help is much appreciated.
*Cheers*
*Arun*
