17 Django Project Ideas that can Make a Positive Impact around You

For more than a decade, I was focused only on the technical part of website building with Django. In the process, I have built a bunch of interesting cultural websites. But I always felt that those sleepless nights were not worthy of the impact.

They say, "Don’t work hard, work smart!" I agree with that phrase, and for me it's not about working less hours. For me, it's working as much as necessary, but on things that matter most.

So after years of collecting facts about life, I connected the dots and came up with make-impact.org – a social donation platform, which became one of the most important long-term projects. All my planning goes around this project.

And I believe I am not the only programmer who sometimes feels that they want to make a positive impact with their skills. So I brainstormed 17 Django project ideas. You can choose one and realize it as a hobby project, open-source platform, startup, or non-profit organization; alone, with a team of developers, or collaborating with some non-technical people.

Idea #1: Low Qualification Job Search

The job market is pretty competitive, and not all people can keep up with the train. You could build a job search website for jobs that don't require high education or lots of working experience. It could be helpful for people with language barriers, harsh living conditions, or those who are very young or very old. You could build it for your city, region, or country.

Idea #2: Discounted Meals and Products

Get inspired from Too Good To Go and build a progressive web app for your city about discounted restaurant meals and shop products whose expiration date is close to the end, but they are still good to eat.

Idea #3: Personal Health Advisor and Tracker

Build a website for setting your personal health improvement goals and tracking the progress. For example, maybe one wants to start eating more particular vegetables every week, jogging daily, lose or gain weight, or get rid of unhealthy addictions. Let people choose their health goals and check in with each progressive step. Allow using the website anonymously.

Idea #4: Online Primary and Elementary School Materials

Some people don't have access to schools in general or miss some classes because of illnesses. You could build a global and open wiki-based primary and elementary school education website for children and adults. It should be translatable and localizable. It would also be interesting to compare the same subject teachings in different countries side-by-side.

Idea #5: Psychological Support for Women

You could build a website with a video chat providing psychological support to discriminated or violently abused women. The help could be given by professionals or emphatic volunteers. The technical part can be implemented using django-channels, WebSockets, and WebRTC.

Idea #6: Rain-harvesting Companies around the World

Rain harvesting is one of the available ways to solve the problem of the lack of drinking water. There could be a platform comparing rain-harvesting companies all around the world. What are the installation prices? What are the countries they are working with? How many people have they saved? This website would allow people to find the most optimal company to build a rain harvesting system for them.

Idea #7: Closest Electric Car Charging Stations

Use the Open Charge Map API and create a progressive web app that shows the nearest electric car charging station and how to get there.

Idea #8: Escrow-based Remote Job Search

As remote jobs are getting more and more popular, there is still a matter of trust between the employees and employers. "Will the job taker complete their job in a good quality?" "Will the company pay the employee on time?" There are Escrow services to fix this issue. These are third parties that take and hold the money until the job is done. You could build a remote job search website promoting the usage of Escrow.com or another escrow service provider.

Idea #9: Open Work Locations

You could build a website listing coworking spaces and cafes with free wifi in your city. It should include the map, price ranges, details if registration is required, and other information necessary for remote workers.

Idea #10: Most Admired Companies

There could be a social website listing the most admired companies to work for in your country. Companies could be rated by working conditions, salary equality, growth opportunities, work relations, and other criteria. Anyone could suggest such a company, and they would be rated by their current and former employees anonymously.

Idea #11: Tiny Houses

The cost of accommodation is a critical problem in many locations of the world. You could develop a website that lists examples of tiny houses and their building schemas and instructions.

Idea #12: Catalog of Recycled Products

You could work on a product catalog with links to online shops, selling things produced from collected plastic. For example, these sunglasses are made of plastic collected from the ocean. Where available, you could use affiliate marketing links.

Idea #13: Information for Climate-change Migrants

You could work on a website for climate-change migrants with information about getting registered, housing, education, and jobs in a new city or country with better climate conditions.

Idea #14: Fishes, Fishing, and Overfishing

Scrape parts of FishBase and create a website about fishes, fishing, and overfishing in your region or the world. Engage people about the marine world and inform them about the damage done by overfishing.

Idea #15: Plant Trees

Create an E-commerce shop or Software as a Service and integrate RaaS (Reforestation as a Service). Let a tree be planted for every sale.

Idea #16: Positive Parenting

Create a progressive web app about positive parenting. For inspiration and information check this article.

Idea #17: Constructive Forum

Create a forum with topic voting and automatic hate speech detection and flagging. For example, maybe you could use a combination of Sentiment analysis from text-processing.com and usage of profanity words to find negativity in forum posts.

It's your turn

I hope this post inspired you. If you decided to start a startup with one of those ideas, don't forget to do your research at first. What are the competitors in your area? What would be your unique selling point? Etc.

Also, it would be interesting to hear your thoughts. Which of the projects would seem to you the most crucial? Which of them would you like to work on?

How to Use Semantic Versioning for Shared Django Apps

When you are building websites with Django, there is no need to track their software versions. You can just have a stable branch in Git repository and update the production environment whenever it makes sense. However, when you create a Django app or package shared among various websites and maybe with multiple people, it is vital to keep track of the package versions.

The Benefits

Versioning allows you to identify a specific state of your package and has these benefits:

• Developers can be aware of which package version works with their websites together flawlessly.
• You can track which versions had which bugs or certain features when communicating with open-source communities or technical support.
• In the documentation, you can clearly see which version of the software it is referring to.
• When fixing bugs of a particular version, developers of the versioned package have a narrower scope of code to check at version control commits.
• Just from the version number, it's clear if the upgrade will only fix the bugs or if it requires more attention to make your software compatible.
• When talking to other developers about a particular package, you can clearly state what you are talking about (yes, developers talk about software versions from time to time 😅).

Semantic Versioning

The most popular versioning scheme is called semantic versioning. The version consists of three numbers separated by dots. Django framework is using it too. For example, the latest stable version at the time of writing is 3.2.9. In semantic versioning, the first number is the major version, the second is the minor version, and the third is a patch version: MAJOR.MINOR.PATCH.

1. MAJOR version introduces backward incompatible features.
2. MINOR version adds functionality that is backward compatible.
3. PATCH version is for backward-compatible bug fixes.

There can also be some versioning outliers for alpha, beta, release candidates rc1, rc2, etc., but we will not cover them in this post.

By convention, the package's version is saved in its myapp/__init__.py file as __version__ variable, for example:

__version__ = "0.2.4"

In addition, it is saved in setup.py, README.md, CHANGELOG.md, and probably some more files.

Changelog

When you develop a Django app or another Python package that you will share with other developers, it is also recommended to have a changelog. Usually, it's a markdown-based document with the list of features, bugs, and deprecations that were worked on between specific versions of your package.

A good changelog starts with the "Unreleased" section and is followed by sections for each version in reverse order. In each of those sections, there are lists of changes grouped into categories:

• Added
• Changed
• Deprecated
• Removed
• Fixed
• Security

This could be the starting template for CHANGELOG.md:

Changelog
=========

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).


[Unreleased]
------------


<!--
### Added
### Changed
### Deprecated
### Removed
### Fixed
### Security
-->

As the new version is released, it will replace the Unreleased section while creating a new Unreleased section above it. For example, this:

[Unreleased]
------------

### Added

- Logging the cookie consent choices in the database because of the legal requirements.

### Fixed

- Disabling the buttons while saving the Cookie Choices so that they are not triggered more than once with slow Internet connections.

would become this:

[Unreleased]
------------

[v0.2.0] - 2021-10-27
------------------

### Added

- Logging the cookie consent choices in the database because of the legal requirements.

### Fixed

- Disabling the buttons while saving the Cookie Choices so that they are not triggered more than once with slow Internet connections.

To keep track of the versions manually would be pretty tedious work, with the likelihood of forgetting one or more files or mismatching the version numbers. Gladly, there is a utility tool to do that for you, which is called bump2version.

Using bump2version

Installation

Install the bump2version utility to your virtual environment the standard way with pip:

(env)$ pip install bump2version

Preparation

In your package's __init__.py file, set the version to 0.0.0:

__version__ = "0.0.0"

Set the version to 0.0.0 in all other files, where the version needs to be mentioned, for example, README.md and setup.py.

Then create setup.cfg with the following content:

[bumpversion]
current_version = 0.0.0
commit = True
tag = True

[bumpversion:file:setup.py]
search = version="{current_version}"
replace = version="{new_version}"

[bumpversion:file:myapp/__init__.py]
search = __version__ = "{current_version}"
replace = __version__ = "{new_version}"

[bumpversion:file:README.md]
search = django_myapp-{current_version}-py2.py3-none-any.whl
replace = django_myapp-{new_version}-py2.py3-none-any.whl

[bumpversion:file:CHANGELOG.md]
search = 
    [Unreleased]
    ------------
replace = 
    [Unreleased]
    ------------
    
    [v{new_version}] - {utcnow:%%Y-%%m-%%d}
    ------------------

[bdist_wheel]
universal = 1

Replace "django_myapp" and "myapp" with your Django app there. If you have more files, mentioning the package version, make sure to have analogous version replacements in the setup.cfg.

Commit and push your changes to the Git repository.

Usage

Every time you want to create a new version, type this in the shell:

$ bump2version patch

or

$ bump2version minor

or

$ bump2version major

followed by the command to build the package:

$ python3 setup.py sdist bdist_wheel

As mentioned before, patch is for the bug fixes, minor is for backward-compatible changes, and major is for backward-incompatible changes.

The bump2version command will use the configuration at setup.cfg and will do these things:

• It will increment the current version number depending on the parameter passed to it.
• It will replace the old version with the new one in the setup.py, myapp/__init__.py, and README.md.
• It will take care of correct versioning in the CHANGELOG.md.
• Then, it will commit the changes and create a tag according to the pattern vMAJOR.MINOR.PATCH there.

Some further details

There are two things to note there.

First, in Markdown, there are two ways of setting the headings:

Changelog
=========

[Unreleased]
------------

is identical to

# Changelog

## [Unreleased]

Usually, I would use the second format for Markdown, but the replacement function in setup.cfg treats lines with the # symbol as comments, and escaping doesn't work either.

For example, this wouldn't work:

[bumpversion:file:CHANGELOG.md]
search = 
    ## [Unreleased]
replace = 
    ## [Unreleased]
    
    ## [v{new_version}] - {utcnow:%%Y-%%m-%%d}

If anybody knows or finds a simple solution with the shorter Markdown variation, let me know.

Second, instead of using setup.cfg, you can use .bumpversion.cfg, but that file is hidden, so I recommend sticking with setup.cfg.

Final words

You can see this type of semantic versioning configuration in the paid Django GDPR Cookie Consent app I recently published on Gumroad.

Happy programming!
