Preventing SQL Injection in Django
I wrote this article for r2c, a security startup I’ve been consulting for. They’ve been building Bento, a program analysis toolkit that can find bug through static anaylsys of Python code. It uses semgrep, a code search tool that understands Python syntax. I’ve been helping them figure out which kinds of checks matter to Django developers. SQL injection is one of the places we decided to start, and I wrote this article to explain the problem, solutions, and how Bento/semgrep can help. -

How To Fix A Bug - Building SaaS #56
In this episode, we picked an issue from GitHub and worked on it. I explained the flow of using test driven development to show how the bug existed in an automated test. We wrote the test, then fixed the code. After that, we did some test refactoring to clean things up. We looked at what the issue was and how it is related to the handling of the Course model in a weekly view in the app. -
How to Check the Running Django Command
It’s occasionally useful to be able to tell which Django manage.py command is being run, in a code path that otherwise has no way of telling. For example, in Speed Up Your Django Tests, I describe how to modify manage.py to default use a test settings file when the test command is run. The way to do this is to copy some of the parsing logic from inside Django, in ManagementUtility.execute(). This looks like: import sys try: command = sys.argv[1] except IndexError: command = "help" if command == "test": # Something specific to running "test" ... Whilst sometimes useful to change a default or add some instrumentation, I’d use this pattern with caution. Such changes will be hard to debug since they’re “at a distance.” It’s normally possible to instead override another part of the given command. In particular, you can write a custom management command that imports and wraps the built-in one, as I showed in Make Django Tests Always Rebuild the Database if It Exists. Warning: Incorrect sys.argv Checks I’ve seen several a few community resources suggesting a similar pattern. However, rather than checking sys.argv[1] they check it with the in operator: import sys if "test" in sys.argv: … -

How I manage multiple development environments in my Django workflow using Docker compose
Hi everyone! Last week I was searching how to manage multiple development environments with the same docker-compose configuration for my Django workflow. I needed to manage a development and a production environment, so this is what I did. Some descriptions on my data: I had around 20 env vars, but some of them where shared among environments. I wanted to do it with as little impact as possible. First, docker-compose help command The first thing I did was run a simple docker-compose --help, and it returned this: Define and run multi-container applications with Docker. Usage: docker-compose [-f <arg>...] [options] [COMMAND] [ARGS...] docker-compose -h|--help Options: -f, --file FILE Specify an alternate compose file (default: docker-compose.yml) # more not necessary stuff --env-file PATH Specify an alternate environment file I went with the -f flag, because I also wanted to run some docker images for development. By using the -f flag I could create a base compose file with the shared env vars (docker-compose.yml) and another one for each of the environments (prod.yml and dev.yml) So I went to town. I kept the shared variables inside docker-compose.yml and added the specific variables and configuration to prod.yml and dev.yml docker-compose.yml: version: "3" services: app: … -

What accomplishments sound like on software engineering resumes
Effective resumes need to contain two things: responsibilities and accomplishments. The first tells the read what your job was; the second, what your results were. Unfortunately, most people fail at the second part. I’ve seen thousands — maybe tens of thousands — of resumes, and most don’t contain accomplishments. This makes it difficult for a hiring manager to get excited about your resume: knowing what you were supposed to do doesn’t tell a reader how well you did that thing. -

Remodeling Data Relationships - Building SaaS #55
In this episode, we’re remodeling! I changed the model relationship between GradeLevel and Course from a ForeignKey (1 to many) to a ManyToManyField. We talked through the change and started fixing all the tests that broke. After explaining the change that I wanted to make and why I want to make it, I explained how a foreign key and many to many relationship at the database level. Once we had the conceptual foundation in place, I started with the documentation. -

How to Move a Django Model to Another App
In my latest article for RealPython I share three ways to tackle one of the most challenging tasks involving Django migrations: moving a model from one Django app to another. The article covers some exotic migration operations and many of the built-in migration CLI commands such sqlmigrate, showmigrations and sqlsequencereset. In the article I also demonstrate important migrations concepts such as reversible migrations, migration plans and introspection.

Variations on the death of Python 2
On April 20th, 2020, a release manager named Benjamin Peterson smashed the “publish” button on Python 2.7.18. The Python 2 release series had already reached the end of its upstream support from the Python core team at the start of the year. I don’t know for certain, but I assumed the timing of the actual final package was meant to occur during PyCon (which, until a global pandemic struck, was scheduled for mid-April), possibly so … Read full entry -
User Interaction With Forms
In the previous Understand Django article, we saw how Django templates work to produce a user interface. That’s fine if you only need need to display a user interface, but what do you do if you need your site to interact with users? You use Django’s form system! In this article, we’ll focus on how to work with web forms using the Django form system. Web Forms 101 Before we can dive into how Django handles forms, we need to have an understanding of HTML forms in general.
