django-template

Template django repository with database connection for testing out OOP and database relations. This is a Python 3 project running Django 3. Clone down this repo and follow the installation instructions to get started with a Django project.

Installation

Pipenv

This project uses pipenv to manage python package requirements. This means that all development should be done within the virtual environment. The following command will initialise the virtual environment and install the dependencies, which can be managed in the Pipfile.

pipenv install --dev

We use the --dev flag to hierarchically install the development and production environments. This means, if you have development requirements such as pytest these will be installed, if you just run pipenv install you development requirements will not.

To activate your virtual environment, run:

pipenv shell

To add a new requirement to your virtual environment 'template', add a new line to the Pipfile with a pinned version. Alternatively, run the following for a production requirement:

pipenv install my-library

Or for a development requirement:

pipenv install --dev my-dev-library

If you want to find the location of your virtual environment, eg. for setting up your IDE run the following from within the shell.

pipenv --venv

Pre-commit

This project uses the black auto formatter which can be run on git commit if you install pre-commit. Black formats the code committed to a pre-defined standard which can be customised to your needs if required. See the docs for the defined code style.

Pre-commit is also configured to run flake8 on commit which will pick up linting errors. See the docs.

To install pre-commit run the following from within your virtual environment.

pre-commit install

Black and flake8 should now run on commit. If there are formatting errors the commit will fail and you will need to re-commit the changes made by black.

Database

You will need to create the database for the application to connect to. The Django project uses postgres which you will need to have installed on your machine. To create the database run the following:

createdb django_db

To migrate any Django relations generated on setup and any existing model relations in your code you will need to run

python manage.py migrate

Once you have some models in your code you will want to create a migration to run against your database. Do this by running

python manage.py makemigrations

Run these migrations using the python manage.py migrate command as above. See the Django docs for all further instructions on setup and development.
