Custom Response Header in Django
So I was wondering on how to build a habit of writing blogs daily, and my friend suggested that we could write about the little things we learn everyday, so we decided to start a series called Today I Learned where we will write about the little things we learn everyday, and thus build a habit I was creating this REST API for one of my clients and I was thinking what is the proof that I made this app, and I was totally blank because only proof I will have is the payment I will be receiving from the client. So I thought, what if I implant something in the response header that will scream that I have created this API or web-app or whatever. In this post, I will be documenting how we can create our own header attribute to responses in Django. Method 1 - Local Header In this you can add a custom header attribute to one response. For example, imaging you are creating an auth APi and you want to send an encrypted token as a response header. For that the view function will be something like this. def auth(req): # DO AUTH RELATED STUFF … -

The Home Stretch - Building SaaS #63
In this episode, we return to the homeschool application that I’m building. I’m in the final stretch of changes that need to happen to make the product minimally viable. We worked on a template, wrote some model methods, and did a bunch of automated testing. We started by adding students to the context of the students index page. With the students in the context, we updated the index page to display the list of students. -
Do you need a task queue in your web app?
Within your web application, some operations, or “tasks”, take an unpredictable time to run. Others take too long to have them executed within the web application’s request/response cycle. Adding a task queue will allow you to: Run longer-running tasks outside the request-response cycle handled by web framework. Actually gunicorn or uwsgi in a production Django1 setup. Run scheduled tasks by not relying on crontab. This usually entails management commands or other forms of standalone scripts. Each needing all environment variables loaded correctly. Without a task queue Let’s say you want to send an email to a user when they submit a form. The process is shown below2: Figure 1. View sends email directly. No queue. This adds an unpredictable time to the expected response time. I.e. those 1-2 seconds taken to: talk to the email provider, over the network receive a response from the email provider, again over the network With a task queue With the task queue in place, the email sending part is done asynchronously. I.e. The unpredictable part is shifted onto the queue. And we don’t really care how long that takes; that is, for returing a response to the user. In case it fails, many task … -

Giving Django Project a “Two Scoops” Configuration
Years back I bought a physical copy of Two Scoops of Django 1.11 after seeing it highly recommended in a book called Hello Web App by Tracy Osborn. Little did I know it was way over my head at the time. With the release of Two Scoops of Django 3.X, and with a lot of recent practice, the book is now only slightly over my head, so I’ve been trying to implement more of the practices recommended in the book. I’ve also been continuing to use Docker and Docker Compose after learning the basics in Django for Professionals by Will Vincent. Fixing Problems? Early on in Two Scoops, the authors discuss how the standard project layout from django-admin startproject leaves a lot to be desired. I definitely have NOT experienced that pain because I don’t have the skills to make any complex projects. I do, however, see the value in getting comfortable with a new layout. It teaches you how some of the module inheritance in Django works. Python import statements are one of the most challenging things for me, personally, so this is a good way to train your coding skills. Let’s talk about two different project layouts. Standard … -
Huey as a minimal task queue for Django
Are you considering adding a task quee to your Django project? Then this article should be useful to you. Adding a task queue will allow you to: Run longer-running processes outside the request-response cycle handled by Django. Actually gunicorn or uwsgi in production. Run scheduled tasks by not relying on crontab. This usually entails management commands or other forms of standalone scripts. Each needing all environment variables loaded correctly. When I was “younger” task queue with Django project meant celery task queue. Now that I’m “older” there are simpler alternatives. The simplest I found was Huey. But the ideas presented here apply to evaluating all task queues for your Django project. Background Frustrated with celery and django-celery In December 2019 I was taking a Django project from Python 2 to 3. This project relied on celery and its integration for Django for asynchronous task processing. Github project link here. This work was mostly done back in 2012-2015. celery’s “Django integration” part was the first problematic part. “Problematic” in the sense that it was not being actively maintained. And Python 3 support was only “planned” at the time. Besides, by testing celery with my Python3 setup I realised how “heavy” it … -

Last Episode On the last episode, we saw Django forms and how to interact with users to collect data. Setting Up A relational database is like a collection of spreadsheets.

Why does Python raise ModuleNotFoundError when modifying Django's INSTALLED_APPS?
Imagine we are installing the third party package django-cors-headers, which I maintain. Step one in its installation process is to install the package, so we run the command: python -m pip install django-cors-headers Step two is to add the module to our settings file’s INSTALLED_APPS. We might add it between the the Django contrib apps and our project’s own core app: INSTALLED_APPS = [ # Django contrib apps "django.contrib.admin", "django.contrib.auth", "django.contrib.contenttypes", "django.contrib.sessions", "django.contrib.messages", "django.contrib.staticfiles", "django.contrib.sites", "django.contrib.humanize", # Third-party apps "corsheaders" # Project apps "example.core" ] Unfortunately with the above INSTALLED_APPS has a bug. Can you spot it? It causes Python to raise the following ModuleNotFoundError when trying to run the server: $ python manage.py runserver Exception in thread django-main-thread: Traceback (most recent call last): File "/.../python3.8/threading.py", line 932, in _bootstrap_inner self.run() ...
