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(..)
datasetID
class Meta:
.....
unique_together = (("datasetID", "filename", "fileVersion"),)
Cheers,
Nader
