mikaponics-back's Introduction

Mikaponics Backend

Introduction

Online aquaponics / hydroponic device monitoring portal implemented in Python and powered by Django.

Instructions

Prerequisites

You must have the following applications installed before proceeding. If you are missing any one of these then you cannot begin.

Python 3.7
virtualenv
redis
Postgres 10

Installation

The following section explains how to setup the application.

Clone a copy of the project somewhere on your machine, we'll be saving to the following locaiton.

mkdir ~/python/github.com/mikaponics;
cd ~/python/github.com/mikaponics;
git clone https://github.com/mikaponics/mikaponics-back.git;
cd mikaponics-back

Setup our virtual environment

virtualenv -p python3.7 env

Now lets activate virtual environment

source env/bin/activate

Now lets install the libraries this project depends on.

pip install -r requirements.txt

Database Setup

This project uses the PostGres database and as a result requires setup before running. The following instructions are to be run in your PostGres console:

drop database mikaponics_db;
create database mikaponics_db;
\c mikaponics_db;
CREATE USER django WITH PASSWORD '123password';
GRANT ALL PRIVILEGES ON DATABASE mikaponics_db to django;
ALTER USER django CREATEDB;
ALTER ROLE django SUPERUSER;
CREATE EXTENSION postgis;

Environment Variables Setup

Populate the environment variables for our project.

./setup_credentials.sh

Go inside the environment variables.

vi ./mikaponics/mikaponics/.env

Edit the file to suite your needs.

Finalization.

Run the following. Please change the password to your own.

redis-cli FLUSHDB;
python manage.py makemigrations
python manage.py migrate
python manage.py init_mikaponics
python manage.py init_crop_data_sheets
python manage.py init_problem_data_sheets
python manage.py create_admin_user "[email protected]" "123password" "Bart" "Mika";
python manage.py setup_resource_server_authorization
python manage.py collectstatic

Register the app with the following social-auth services. Also read this tutorial on setting these up.

If you would like to have some random test data available for your app, feel free to run any of theses.

# Smallest dataset
python manage.py seed_database 1 1 1000

# Small dataset
python manage.py seed_database 5 10 2500

# Medium dataset
python manage.py seed_database 25 20 5000

# Large dataset
python manage.py seed_database 100 30 10000

# Gigantic dataset
python manage.py seed_database 10000 50 100000

# Epic dataset
