Python – Django Girls – Introduction to Django – Video

Months ago, I was planning to take part in the #RailGirls event in Sofia, and I was even a partner in the event. Anyway, as it was postponed up to somewhere in the future, I have decided to go through the DjangoGirls tutorial and to record it. To be honest, I was expecting that the tutorial is “a walk in the park”, but somehow it was a bit more advanced, including JavaScript, Django, OOP Python, SqlLite3, command prompt techniques for adding data to a database and etc.

Watch this video on YouTube

Was it good? I don’t know, it took me about 3 hours to record it and another 6 to edit it and upload it to YouTube in its final form. Now, when I think about it, I should have read the tutorial before stepping into it. Anyway, this way I have shown that even seasoned developers make rookie mistakes, when they come a bit unprepared into some kind of a project, that they are not currently working on. Thus, all the errors are staying as they were. Plus, I really do not have the desire to edit them out 🙂

Anyway, the whole code is as usually in my GitHub repo here – https://github.com/Vitosh/Python_personal/tree/master/YouTube/002_DjangoGirls.

The core of the project are the following 5 files:

blog/views.py

    posts = Post.objects.all() #filter(published_date__lte=timezone.now()).order_by('published_date')
    return render(request, 'blog/post_list.html', {'posts': posts})


def post_detail(request, pk):
    post = get_object_or_404(Post, pk=pk)
    return render(request, 'blog/post_detail.html', {'post': post})


def post_new(request):
    if request.method == "POST":
        form = PostForm(request.POST)
        if form.is_valid():
            post = form.save(commit=False)
            post.author = request.user
            post.published_date = timezone.now()
            post.save()
            return redirect('post_detail', pk=post.pk)
    else:
