Prevent Unintended Data Modification With django-read-only
Last week I released a new Django package, django-read-only. It provides a read-only mode for Django’s database layer. This can be useful to reduce the risk of giving developers access to your production instances. Access to manage.py shell on production allows you to iterate faster when creating new features, migrations, and backfills. But with great power comes great accident potential. It’s all too easy to mix up terminal sessions and run the wrong thing on production. Even if the individual chance of making such a mistake is small, multiplying it by team size and time, the chance of a mistake can become almost certain, and the potential cost can be huge. Rather than locking your team members out of production, you can protect against these mistakes with django-read-only. The package uses some always-installed database instrumentation to block database access when its read-only mode is active. You can then enable read-only mode for interactive production sessions via an environment variable or setting, so when developers access production writes are disabled by default. Read-only mode can be disabled, so the occasional manual data fix is still possible. For example, if the environment variable was set, we couldn’t log into the shell and … -

Make A Landing Page - Building SaaS #75
In this episode, I added a landing page design to the app that I’m building. By using a Tailwind CSS landing page template, I could fit the design in with my existing CSS tools. I showed some available templates that I discovered while researching for Tailwind-based landing pages. Once I found a decent template, I copied the source of sample landing page into my index page template. Since I copy and pasted from the landing page, the initial look was terrible. -

Migrate Away from cmsplugin-filer in a Few Easy Steps
Companion code for this post: https://github.com/ImaginaryLandscape/deprecate_cmsplugin_filer If you've been building projects using django CMS for any length of time, chances are you're familiar with Divio's cmsplugin-filer application which provided image, link, file, folder and video plugins for interacting with django-filer. And if you're here, chances are you're aware that cmsplugin-filer has now been deprecated in favor of their standalone djangocms-[picture/file/link/video] plugins. Unfortunately, for a production project that already has hundreds of these cmsplugin-filer objects, simply switching to the newer packages is no simple task. You really only have a couple options — switching over to a fork with the hopes that it will continue to be supported as future Django versions are released, or setting about to migrate all of your existing plugins. Here we'll walk you through the latter. Let's start with a word of caution. This remains experimental code. Taking these steps will make irreversible changes to your database objects. It's highly recommended you run this on a development version of your project before modifying production data to identify any issues that may arise. At the least, make a backup of your database to allow restoring if needed. In searching for an existing solution to this problem, you may have … -

Deploying Django > 3.1 (async) with Uvicorn and Nginx
Django async Django 3.1 shipped with async views. This means we can start using async/await in Django views: async def index(request): res = await do_stuff_async() # return your view To reap all the benefits of this feature, you have to run Django under an ASGI server like Daphne, Uvicorn, or Hypercorn.

Check Web App Security With Bandit - Building SaaS #74
In this episode, I integrated the bandit static analysis tool to do automated security checking of my code before each commit. We talked about pre-commit and how to add in a new hook. After finishing that tool addition, we got deep into Django while removing some messages inserted by django-allauth on sign up. We began by talking about what the bandit tool does and how it works. Once I explained bandit, I focused on the bandit documentation to see how to add the tool. -

Python, Django top frameworks and it's comparison
Python is a general-purpose programming language. We can use python for so many applications including web applications. Framework is a collection of modules or packages, which helps in writing a web application or helps in developing a web application. We don't have to worry about low level details such as protocols, socket, thread management when working with a framework. Framework makes the developer’s life smarter and easier by giving a structure for application development. They automate the implementation of common solutions, which gives flexibility to developers to focus only on app logic instead of routine. They provide common backend fast reliable and scalable easily maintainable web applications. Frameworks provides functionality to perform the following operations for developing web applications. URL Routing. Input form handling and validation. Output Formats with Templating Engine HTML, XML, JSON. Data Connection, manipulating using ORM mappers. Web security. Session Storage and retrieval. URL Routing Mechanism of URL mapping is staying at the same web page when you click on some other link. Input Form handling and Validation The data entered into a form needs to be in the right format, and certain fields are mandatory for effective use of form.

Dynamically Regrouping QuerySets In Templates - Building SaaS #73
In this episode, we worked on a new view to display course resources. While building out the template, I used some template tags to dynamically regroup a queryset into a more useful data format for rendering. I started a new view before the stream to display content, but I had not filled it in before the stream started. We added new data to the context, and did some adjustments to the URL based on the required inputs for the view. -
