Can I create model in Django without automatic ID?

Question

I need a table without a primary key (in Django it was created automatically). So my question is: Can I create a model without an ID/primary key?

I\'m u

Answer 1

No, you can't. Excerpt from the documentation:

Each model requires exactly one field to have primary_key=True (either explicitly declared or automatically added).

Answer 2

You can create a model without an auto-incrementing key, but you cannot create one without a primary key.

From the Django Documentation:

If Django sees you’ve explicitly set Field.primary_key, it won’t add the automatic id column.

Each model requires exactly one field to have primary_key=True (either explicitly declared or automatically added).

Answer 3

I've found the solution.

Since django need Primary Key (either it's composite or single-field ID) so, I've tried to set primary_key=True in every fields in its composite-key combination, and add those fields in Meta and groups in unique_together

class ReportPvUv(models.Model):
    report_id = models.ForeignKey(Reports, primary_key=True)
    rdate = models.DateField(primary_key=True)
    fdate = models.DateTimeField(primary_key=True)
    ga_pv = models.BigIntegerField()
    ga_uv = models.BigIntegerField()
    ur_pv = models.BigIntegerField()
    ur_uv = models.BigIntegerField()
    da_pv = models.BigIntegerField()
    da_uv = models.BigIntegerField()

    class Meta:
        db_table = 'report_pv_uv'
        unique_together = ('report_id', 'rdate', 'fdate')

and when I run makemigrations, there are no ID field in it's migrations script :D

thanks everybody
