About

It is important to control your budget and know where your money goes. I've tried lots of different apps and methods, but none have really convinced me. So I designed and developed IHateToBudget, a simple and efficient application that meets my needs.

And it's also available for you.

Features

A basic authorization system exists but this application is not intended to be hosted on a public network (yet?). It is designed to be self-hosted locally (e.g. on a Raspberry Pi) and used by a few users within the same household.

1. Categories

Define categories, and their color.

2. Sheet

Add dated and categorized expenses. They are automatically grouped by month (i.e. sheet).

3. Overview

Analyze the overall statistics.

4. History

Explore and filter all expenses.

Installation & Configuration

Docker method

The following instructions are guidelines. You're free to adapt these to your needs.

1. Install Docker and docker-compose, if you haven't already.

2. Clone the repository:

   git clone https://github.com/bminusl/ihatetobudget.git
   cd ihatetobudget

3. Create a copy of:

   • docker-compose.yml.example as docker-compose.yml
   • docker-compose.env.example as docker-compose.env
   • Caddyfile.example as Caddyfile

   cp docker-compose.yml.example docker-compose.yml
   cp docker-compose.env.example docker-compose.env
   cp Caddyfile.example Caddyfile

   Note: Making copies ensures that you can git pull (or equivalent) to receive updates without risking merge conflicts with upstream changes.

4. Edit docker-compose.env and adapt the following environment variables:

   • DJANGO_SECRET_KEY: This is the secret key used by Django.

     See https://docs.djangoproject.com/en/3.1/ref/settings/#std:setting-SECRET_KEY for more information.

   Currency formatting

   In IHateToBudget, money is represented by positive decimals of the form "xxxxxxxx.yy". The user is free to change the formatting to use the currency of their choice, by setting the following environment variables:

   • CURRENCY_GROUP_SEPARATOR: A single character which separates the whole number into groups of 3 digits.¹
   • CURRENCY_DECIMAL_SEPARATOR: A single character that separates the whole part from the decimal part.¹
   • CURRENCY_PREFIX: A string placed in front of the number.¹
   • CURRENCY_SUFFIX: A string placed behind the number.¹

   By default, it formats money as French euros. For instance, here's how to format as US dollars:

   CURRENCY_GROUP_SEPARATOR=,
   CURRENCY_DECIMAL_SEPARATOR=.
   CURRENCY_PREFIX=$
   CURRENCY_SUFFIX=
   

   ---

   ¹: Note: If it contains spaces, make sure to use non-breaking spaces. This is simply to prevent visual "glitches".

5. Run docker-compose up -d. This will build the main image, and create and start the necessary containers.

6. To be able to login, you will need a (super) user. To create it, execute the following commands:

   docker-compose run --rm ihatetobudget pipenv run python manage.py migrate
   docker-compose run --rm ihatetobudget pipenv run python manage.py createsuperuser

   This will prompt you to set a username, an optional e-mail address and finally a password.

7. You should now be able to visit your IHateToBudget instance at http://127.0.0.1:80. You can login with the username and password you just created.

Updating

Docker method

The following instructions are guidelines. You're free to adapt these to your needs.

1. Navigate to the root of the repository.

2. Run docker-compose down -v. This will stop all containers.

   Note: Volumes are also removed (-v), see why.

3. Create a backup of the database—just in case—, e.g. run cp db.sqlite3 db.sqlite3.bak.

4. Upgrade the codebase to the desired revision, e.g. run git pull.

5. Rebuild the image:

   docker-compose build

6. Migrate the database:

   docker-compose run --rm ihatetobudget pipenv run python manage.py migrate

   This action will synchronize the database state with the current set of models and migrations.

7. Run docker-compose up -d. This will create and start the necessary containers.

Contributing

I maintain this project primarily for my own use. If you can think of any relevant changes that should be incorporated into the code, you can contribute by opening an issue or submitting a pull request.

See the Developer documentation section below for more information.

Developer documentation

This section is WIP

The development environment

Set up

1. Install Pipenv, if you haven't already.

   Pipenv is used to manage dependencies and the virtual environment. Note: IHateToBudget currently targets Python 3.8, so make sure it is installed too.

2. Set up the virtual environment by executing the following command:

   pipenv install --dev

   This action will install both develop and default packages.

Usage

When you start a new development session, run the following command:

pipenv shell

This action spawns a shell within the virtualenv.

---

You should now be able to work.

Since IHateToBudget is primarily a Django project, you should read Django's documentation if you are not familiar with it already.

Code quality

pre-commit hooks are used to keep the code clean, namely:

• black
• flake8
• isort

Execute the following command to run pre-commit against all files:

pre-commit run --all-files

Testing

• To run tests, execute the following command:

  python manage.py test

• Alternatively, coverage can be used to measure code coverage:

  coverage run --source='.' manage.py test
