Re: Using Primary key in two fields

Hi Rakhee,

Could you try following ? :

icatid = models.BigIntegerField(db_column='ICatID') makedate = models.DateTimeField(db_column='MakeDate') revdate = models.DateTimeField(db_column='RevDate', blank=True, null=True) makeid = models.BigAutoField(db_column='MakeId') class Meta: unique_together = (('icatid', 'makeid'),)

Hi Everyone,

I have a scenario where one field needs to be a primary key and another field needs to be an AutoField....and Autofield requires a condition primary_key = true

I get this error 

django_reports.MstCompositionFm.makeid: (fields.E100) AutoFields must set primary_key=True.

django_reports.MstSalarystructure: (models.E026) The model cannot have more than one field with 'primary_key=True'

This is my case:

icatid = models.BigIntegerField(db_column='ICatID', primary_key=True)

makedate = models.DateTimeField(db_column='MakeDate')

revdate = models.DateTimeField(db_column='RevDate', blank=True, null=True)

makeid = models.BigAutoField(db_column='MakeId', primary_key=False)

It would be of great help if anyone could figure out whats the solution

Thanks in Advance,

Rakhee
