Regarding getabsoluteurl function in model based views

Using Django
1

I am using model based views like ListView and DetailedView, and for performing CRUD operations i am facing problem in get_absolute_url function

Models.py file

from django.urls import reverse
# Create your models here.
class Company(models.Model):
    name=models.CharField(max_length=128)
    location=models.CharField(max_length=64)
    ceo=models.CharField(max_length=64)


def get_absolute_url(self):
    return reverse('detail',kwargs={'pk':self.pk})

urls.py

from django.contrib import admin
from django.urls import path
from testapp import views
urlpatterns = [
    path('admin/', admin.site.urls),
    path('home/', views.CompanyListView.as_view()),
    path('<int:pk>', views.CompanyDetailView.as_view(),name='detail'),
    path('create/', views.CompanyCreateView.as_view()),

]

views.py

from django.shortcuts import render
from testapp.models import Company
from django.views.generic import ListView,DetailView,CreateView,UpdateView,DeleteView
# Create your views here.
from django.urls import reverse
class CompanyListView(ListView):
    model=Company

class CompanyDetailView(DetailView):
    model=Company

class CompanyCreateView(CreateView):
    model=Company
    fields=('name','location','ceo')

In the company_detail html:-

<!DOCTYPE html>
{% extends 'testapp/base.html'  %}
{%block body_block%}
<h1>{{company.name}} Information</h1>
<h2>Location:{{company.location}}</h2>
<h2>Name of CEO:{{company.ceo}}</h2>
{%endblock%}

In the company_form.html:-

<!DOCTYPE html>
{% extends 'testapp/base.html'  %}
{%block body_block%}

<h1>Employee Insert Info  Form</h1><hr>
<form  method="post">
  {{form.as_p}}
  {%csrf_token%}

  <input type="submit" class="btn btn-lg btn-primary" value="Insert">
</form>


{%endblock%}

In the company_list.html:-

<!DOCTYPE html>
{% extends 'testapp/base.html'  %}
{%block body_block%}

<h1>List of all companies</h1><hr>
{%for company in company_list%}
<h2><a href="/{{company.id}}">{{company.name}}</a></h2>
{%endfor%}
{%endblock%}

I am getting the following error:-

Traceback (most recent call last):
  File "C:\Users\HP\AppData\Local\Programs\Python\Python39\lib\site-packages\django\views\generic\edit.py", line 116, in get_success_url
    url = self.object.get_absolute_url()
AttributeError: 'Company' object has no attribute 'get_absolute_url'

During handling of the above exception, another exception occurred:

Assuming the forum hasn’t messed up the formatting of your code that you posted, the issue is that the get_absolute_url method you’ve defined is not part of the Company class. (It’s not indented)
