I have a Homework model that I want to filter based on the date(date_view) to show the homework. It looks like this-
Homework model
class Homework(models.Model):
hw_id = models.CharField(unique=True, max_length=50)
homework = models.TextField()
subject = models.ForeignKey(Subject, on_delete=models.CASCADE)
class_id = models.ForeignKey(Classes, on_delete=models.CASCADE)
date_added = models.DateTimeField(auto_now_add=True)
date_updated = models.DateTimeField(auto_now=True)
date_view = models.DateTimeField(default=datetime.now())
But when I try to filter like this-
hw = Homework.objects.filter(class_id=class_id).filter(date_view__gte='homework__date_added')
I get this error-
['“homework__date_added” value has an invalid format. It must be in YYYY-MM-DD HH:MM[:ss[.uuuuuu]][TZ] format.']
I think I am filtering the data in the wrong way. But how should I filter the data?
You can refer to a field with an F
object [Django-doc] :
from django.db.models import F
hw = Homework.objects.filter(
class_id=class_id,
)
