Requirements

^top

Docker

• Check out this Wiki to see how to run docker for this project.

Python 3

Postgres

Git

Redis

Setting up an S3 Account

• Follow https://django-storages.readthedocs.io/en/latest/backends/amazon-S3.html and https://www.caktusgroup.com/blog/2014/11/10/Using-Amazon-S3-to-store-your-Django-sites-static-and-media-files/ to setup s3 bucket, and download access keys.

Getting Started

^top

Setting up a development environment

1. Create database and user in Postgres for keralarescue and give privileges.

psql user=postgres
Password:
psql (10.4 (Ubuntu 10.4-0ubuntu0.18.04))
Type "help" for help.

postgres=# CREATE DATABASE rescuekerala;
CREATE DATABASE
postgres=# CREATE USER rescueuser WITH PASSWORD 'password';
CREATE ROLE
postgres=# GRANT ALL PRIVILEGES ON DATABASE rescuekerala TO rescueuser;
GRANT
postgres=# \q

2. Clone the repo.

git clone https://github.com/IEEEKeralaSection/rescuekerala.git
cd rescuekerala

3. Copy the sample environment file and configure it as per your local settings.

    cp .env.example .env

Note: If you cannot copy the environment or you're facing any difficulty in starting the server, copy the settings file from https://github.com/vigneshhari/keralarescue_test_settings for local testing.

4. Install dependencies.

pip3 install -r requirements_debug.txt

5. Run database migrations.

    python3 manage.py migrate

6. Setup static files.

    python3 manage.py collectstatic

7. Run the server.

    python3 manage.py runserver

8. Now open localhost:8000 in the browser

That's it!

Setup using docker-compose

Pre-requisites

• Docker
• Docker Compose

Run the scripts in the root directory

• docker-start.sh - to start the services.

• docker-stop.sh - to stop the services.

• docker-restart.sh - to rebuild and restart the services.

Creating migration files

^top

If your code changes anything in models.py, you might need to make changes in database schema, or other constraints. To create migrations files, run python3 manage.py makemigrations --settings=floodrelief.settings after making your changes. Also make sure to add these files in the commit.

Running tests

^top

When running tests, Django creates a test replica of the database in order for the tests not to change the data on the real database. Because of that, you need to alter the Postgres user that you created and add to it the CREATEDB privilege:

ALTER USER rescueuser CREATEDB;

To run the tests, run this command:

python3 manage.py test --settings=floodrelief.test_settings

---

Enable HTTPS connections

^top

Certain features (example: GPS location collection) only work with HTTPS connections. To enable HTTPS connections,follow the below steps.

Create self-signed certificate with openssl

$openssl req -x509 -newkey rsa:4096 -keyout key.key -out certificate.crt -days 365 -subj '/CN=localhost' -nodes

[https://stackoverflow.com/questions/10175812/how-to-create-a-self-signed-certificate-with-openssl#10176685]

Install django-sslserver

$pip3 install django-sslserver

Update INSTALLED_APPS with sslserver by editing the file floodrelief/settings.py (diff below)

 INSTALLED_APPS = [
+    'sslserver',
     'mainapp.apps.MainappConfig',
     'django.contrib.admin',

Note: Make sure that this change is removed before pushing your changes back to git

Run the server

python3 manage.py runsslserver 10.0.0.131:8002  --certificate /path/to/certificate.crt --key /path/to/key.key

In the above example the server is being run on a local IP address on port 8002 to enable HTTPS access from mobile/laptop/desktop for testing.

Please find issues that we need help here. Go through the comments in the issue to check if someone else is already working on it. Don't forget to drop a comment when you start working on it.

Always start your work in a new git branch. Don't start to work on the master branch. Before you start your branch make sure you have the most up-to-date version of the master branch then, make a branch that ideally has the bug number in the branch name.

1. Before you begin, Fork the repository. This is needed as you might not have permission to push to the main repository

2. If you have already clone this repository, create a remote to track your fork by

   git remote add origin2 [email protected]:tessie/rescuekerala.git
   

3. If you have not yet cloned, clone your fork

   git clone [email protected]:tessie/rescuekerala.git
