Attempt to reproduce "Django 3 Tutorial & CRUD Example with MySQL and Bootstrap" on Fedora 33 KVM Guest

Regardless I've spent some time to overcome several issues (typos) in Original Howto

https://www.techiediaries.com/django/django-3-tutorial-and-crud-example-with-mysql-and-bootstrap/

I strongly believe that mentioned article is one of the best for beginners to test the taste of Django 3.1.16

To accomplish the task  following issues have to be fixed :-

The core fix in views.py  :-

 

def edit(request, pk, template_name='crudapp/edit.html'):

    contact = get_object_or_404(Contact, pk=pk)

    form = ContactForm(instance=contact)

    if request.method == 'POST':

        form = ContactForm(request.POST, instance=contact)

    # form = ContactForm(request.POST or None, instance=post)

    if form.is_valid():

        form.save()

        return redirect('index')

    return render(request, template_name, {'form':form})

 

Original code provided

def edit(request, pk, template_name='crudapp/edit.html'):
    contact = get_object_or_404(Contact, pk=pk)
    form = ContactForm(request.POST or None, instance=post)
    if form.is_valid():
        form.save()
        return redirect('index')
    return render(request, template_name, {'form':form})

The code above doesn't allow edit records in mariadb database ( OS Linux Fedora 33 Server ) 

Another fix add import to urls.py 

from django.contrib import admin 

from django.urls import path 

from crudapp import views
