Made my first website in Microsoft Word at age 13, when I discovered the "save as html" button. Since then I've journeyed various computing languages, eventually settling for Python. I love diving into the core of my favorite framework - Django - discover and writing about new stuff.

Django offers a great deal of hidden functionality - secret gems - if you know where to look. In this serie I am showing tips and tricks to get the most out of Django.
Use 93x less queries using patched raw_id_fields and prefetching
When working in the Django admin with a lot of users, you might sometimes want to offer the functionality to users to choose which columns they want to see in the changelist page. For some users some columns might be more relevant than to others. One...
Expiring a superuser in Django after a due date
At Wundermart we started saving monetary amounts in Django, we naively started with DecimalField(decimal_places=2) for our financial data. After some time we realized that you will lose data this way when applying calculations, for example: €100 * 0....
Suppose you change your Django model instance, how do you know if the data actually changed? There are a few ways to achieve this, for example using django-simple-history which will add a database entry for every change to keep history. However, you ...
The django-simple-history package is awesome as it shows you all the activity on a certain Django model object. It allows seeing how it was mutated over time and who changed it. However, there is one caveat: you cannot easily see what objects were de...
When using the requests library in Python you can use some built-in auth mechanisms like HTTPBasicAuth and HTTPDigestAuth. However, I could not find any package that allows doing a simple JSON Web Token (JWT) authentication, so I decided to make a snippet.
jwt_auth = JWTAuth(
auth_url='https://endpoint.example/api/v1/auth',
api_payload={
'api_key': '<API_KEY>',
'api_secret': '<API_SECRET>',
}
)
# Using it directly
requests.get('some-url', auth=jwt_auth)
# Or when applied to a session for all requests:
session = requests.Session()
session.auth = jwt_auth
JWTAuth needs to know your auth_url and api_payload to be able to authenticate with the server on your first request. It will only work when you receive back an access and refresh token. Based on your situation and API response, you might need to change this a little to make it work.
