Formsets In Django Class-based Views

 Dec. 14, 2020    0 comments 

Django offers several out-of-the-box class-based views, including CreateView and UpdateView, that allow you to quckly implement basic CRUD functionality in your web-application without much of boilerplate code. Under the hood CreateView and UpdateView classes create, validate and save a Django ModelForm instance tied to your model class.

Blog Environment Upgrade

 April 21, 2017    0 comments 

Previously, this blog run on Django 1.8 and Python 3.4, but after a new Django LTS release — 1.11 — I decided that it's time to upgrade this blog to the new Django version and to bump Python version as well. The upgrade process was simple: I created a new virtual environment, installed all the dependencies and pointed Pythonanywhere to this new environment. The blog itself required only one minor change of the sitemap view because URL patterns no longer accept view names as strings, e.g. 'django.contrib.sitemaps.views.sitemap', but require proper callable view objects (previously, both variants were supported).

Now this blog runs on Django 1.11 and Python 3.5 (Pythonanywhere does not provide Python 3.6 yet).

Unfortunately, Django template languages was not among them so I decided to fill-in this gap. And because Jinga2 template syntax is very similar, I decided to make one language definition for both.
