Happy to send Model if needed but at the moment I'm unable to run the

please copy and paste your code - it is easier for us to help when we
see what you are doing

Here is the code. I've added some notes to try and explain what I think
I'm doing
class Fringe(models.Model):

description = models.CharField(max_length=50)

return self.code
class Detail(models.Model):
account = models.ForeignKey(Account, related_name= 'account_account')

'cashflow_code')
