Vesion 3.1.5 returns null for an object pointed to non PK in referred table.

Version 3.1.3 and older versions are working correctly in situation if a field is a foreign key to a non PK of pointed table.
3.1.5 returns 'null'

@3hedgehogs Could you provide some example code/a reproducible example? Would be great if you follow the template for bug report too.

Unfortunately I'm not a django programmer, just temporary support our internal project till we find a person to continue develop it.

Used models:

class HourlyLimit(mta_gui.models.MultiSettingsExtension, mta_gui.models.Model):
    id = models.AutoField(db_column="limitid", primary_key=True)
    source = models.ForeignKey(
        to="pools.IpAddress",
        on_delete=models.CASCADE,
        db_column="OutPort",
        to_field="outport",
        related_name="hourly_limits",
    )
    destination = models.ForeignKey(
        to="destinations.Destination",
        on_delete=models.CASCADE,
        db_column="DestinationId",
        related_name="hourly_limits",
        help_text="DEFAULT means limit is for all destinations",
    )
    value = models.IntegerField(
        db_column="Value", default=0, help_text="0 means this public IP is disabled"
    )
    memo = models.TextField(db_column="Memo", blank=True, null=True)
...

class IpAddress(mta_gui.models.MultiSettingsExtension, mta_gui.models.Model):
    id = models.AutoField(db_column="IpId", primary_key=True)
    ip = models.CharField(db_column="Ip", max_length=60, unique=True)
    ip_range = models.ForeignKey(
        to="IpRange",
        on_delete=models.CASCADE,
        db_column="ipRangeId",
        related_name="ip_addresses",
    )
    domain = models.CharField(db_column="Note", max_length=255)
    outport = models.SmallIntegerField(db_column="OutPort", unique=True)
    ip_pools = models.ManyToManyField(IpPool, related_name="ip_pools")
    ip_pool = models.ForeignKey(
        to="IpPool",
        on_delete=models.SET_NULL,
        db_column="IpPoolId",
        blank=True,
        null=True,
        related_name="ip_addresses",
        verbose_name="IP pool",
    )
...

destination is returned correctly but
source is always null for version 3.1.5

Sorry, if information is not enough I will close this issue

I see. Would definitely prefer a minimum reproducible example so we can create a test for it and see which change caused the issue, but I understand your situation. You can leave the issue open.

There're not a lot of PRs merged from 3.1.3 to 3.1.5. I suspect it's due to either #1411 or #1446.
