AttributeError: 'Post' object has no attribute 'get_absolute_url'

[Mayur Pabari]

Below is the code of views.py. I am getting error when calling 
HttpResponseRedirect in update and create method. So please let me know 
how can i solve this ?

from django.shortcuts import render, get_object_or_404
from django.http import HttpResponse, HttpResponseRedirect

from .forms import PostForm
from . models import Post

def post_create(request): #create Method
    form = PostForm(request.POST or None)
    if form.is_valid():
        instance = form.save(commit=False)
        instance.save()
        return HttpResponseRedirect(instance.get_absolute_url())

    context = {
    "form" : form,
    }
    return render(request, "post_form.html", context)
def post_list(request): #list method
    queryset = Post.objects.all()
    context = {
    "object_list": queryset,
    "title": "List"
    }
    return render(request, "index.html", context)

def post_update(request, id=None): #update Method
    instance = get_object_or_404(Post, id=id)
    form = PostForm(request.POST or None, instance=instance)
    if form.is_valid():
        instance = form.save(commit=False)
        instance.save()
        return HttpResponseRedirect(instance.get_absolute_url()) #i am getting error here

    context = {
        "title": instance.title,
        "instance": instance,
        "form": form,
    }
    return render(request, "post_form.html", context)

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 :)
