Setup & dependencies

• Python 3.8.5
• Django 3.1.2
• Postgres 12.5

The following steps will walk you thru installation on a Mac. Linux should be similar. It's also possible to develop on a Windows machine, but I have not documented the steps. If you've developed django apps on Windows, you should have little problem getting up and running.

Create Database

Create the database by running the following commands in a psql shell. If you're using Postgres.app, click the Postgres.app icon in your toolbar and select "Open psql".

create database "inventory";
create user "macair";
ALTER ROLE "inventory" WITH PASSWORD 'inventory';
ALTER USER macair CREATEDB;
CREATE EXTENSION postgis;

Setup Django Server (Mac)

We're using python3 instead of python2.x. If you don't have python3 installed, install Homebrew, then…

brew install python3.8

Assuming you've cloned the repository, open Terminal and cd ~/your/path/to/inventory.

Create a python virtual environment:

virtualenv venv --python=python3.8

Activate it:

source env/bin/activate

Install the python dependencies which includes django and other libraries.

pip3 install -r requirements.txt

Run server locally

./manage.py migrate
./manage.py runserver

If PSQL error raise please follow the command:

pip install psycopg2-binary
