MyHydro

Simple Django app for hydro systems management.
Contains features such as user authorization and authentication, CRUD operations for hydro systems, sensors and measurements.
Views are tested in test_views dirs. App is also packed into docker network.
Each user can manage one's systems (add them, update info, delete, read details). After creating system, one can add sensors to it. After setting up sensors use "new-measurement" endpoint to add values read by them to PostgreSQL db.
Api documentation is available at http://localhost:8000/api/docs/
Follow README to set up and use the app properly.

1) Project Setup

1.1) Install virtual environment

To isolate the dependencies of this project, it's recommended to use a virtual environment.

python -m venv .venv
.venv/Scripts/activate

1.2) Clone repository

git clone https://github.com/saworz/hydro

1.3) Install dependencies (or go to 1.7 and use docker)

cd hydro
pip install -r requirements.txt
pip install -r requirements_dev.txt

1.4) Create and setup PostgreSQL database:

createdb --username=postgres hydro
export DATABASE_URL=postgres://postgres:[email protected]:5432/hydro

1.5) Apply migrations

python manage.py migrate

1.6) Run server

python manage.py runserver

1.7) Or just run it in docker network

cd hydro
docker-compose up

2) User setup

2.1) Register new user

2.2) Login into existing account

First you need to setup csrf global var. Tokens are passed as cookies automatically.
And now you can log in.

3) Project workflow

3.1) Populatedb for quick start! (or go to 3.2 and do everything manually)

To avoid setting up user, systems, sensors, measurements manually you can run this command and enjoy some dummy data.

python manage.py populatedb

Now you can investigate the data in database or using GET endpoints described in api schema (step 3.5).

3.2) Create new system

Let's say you just finished building new system that contains only 1 ph sensor and 1 temperature sensor and you want to save its measurements.

Note: remember to add csrf token to headers:

Now you can make system create request

3.3) Add sensors

Now make two requests to create two sensors for this system

3.4) From now on measurements can be saved in the database using new-measurement endpoint

Let's add sample measurements for both of sensors

3.5) Now you can go back to system details and check last 10 measurements

3.6) There are also some other endpoints for updating or reading your systems and sensors

3) Tests

To run tests execute

pytest
