Django use datetime.date() as input for DateField to achieve past date input

I have a simple model where I want to input a past date as the DateField in the model.

import datetime

class BalanceSheet(models.Model): 

     ticker = models.ForeignKey(Security, on_delete=models.CASCADE, related_name="balance_sheet")

     date = models.DateField(default=datetime.date)

but I receive the following error when trying to add a record in the admin panel

TypeError at /admin/financials/balancesheet/add/
function missing required argument 'year' (pos 1)

The default you are passing requires an argument, that is why you are getting the error. if you pass datetime.date.today you can alter the date to a previous date once the record has been created.

Try to replace

 ...
 date = models.DateField(default=datetime.date)

with:

import datetime

...
date = models.DateField(default=datetime.date.today)

Or:

from datetime import datetime

...    
date = models.DateField(default=datetime.now)
