The code of your model would be more interesting. According to the
error, Post have no method get_absolute_url. That method isn't
provided by models.Model, you have to write it. A way to do it is like
that:
from django.db import models
from django.urls import reverse
class Item(models.Model):
name = models.CharField(max_length=32)
def get_absolute_url(self):
return reverse('app:item', kwargs={'pk':self.pk})
Also, I would suggest you to have a look at class based view,
especially those handling form [1]. That's unrelated to your problem
but might save you time in the future :)
