Description
class Website(models.Model):
id = models.IntegerField(primary_key=True)
dfp_id = models.IntegerField()
name = models.CharField(maxlength=300)
url = models.CharField(maxlength=150)
class Report(models.Model):
id = models.IntegerField(primary_key=True)
site = models.ForeignKey(Website, to_field='dfp_id')
444549 is a valid dfp_id in the Website model.
Report.objects.filter(site=444549) <-- Returns results. good.
Report.objects.filter(siteid=444549) <-- Returns results, but it shouldn't.
Report.objects.filter(sitedfp_id=444549) <-- No results, but it should.
