No. And that's the source of the problem you are seeing. If you just
want the ForeignKey to be unique, you can add a unique=True
Thank you for this conceptual remark.
Could the "ForeignKey" filed be a "primary_key at the same time?
datasetID = models.ForeignKey(Dataset, db_column="datasetID",
primary_key=True)
I suppose I can define a group of fields as "primary_key" by using of
the next statement :
Class Model(..)
A model can only use one field as its primary key and
Distributequeue.objects.get() should only return one object.

Hallo,
I have a model as following:
class Distributequeue(models.Model):
datasetID = models.ForeignKey(Dataset, db_column="datasetID",
primary_key=True)
filename = models.CharField(primary_key=True, maxlength=240)
fileVersion = models.CharField(primary_key=True, maxlength=48)
4 matches
