Study Portal

About

This is the backend API repository for Study Portal intended to be used by Study Portal React Web App and the mobile app.

Prerequisites

1. Install PostgreSQL service.
2. Obtain a credentials.json from the author/generate one yourself and place it in studyportal/drive.
3. Create a .env file from .env.sample and change the fields as appropriate.

Optional Prerequisites:

These are required to get the auth running for development setup.

1. Setup Arceus and Falcon locally or get a remote instance for development/testing.
2. Register study as an app in Arceus and make changes to .env.

Setup Instructions

Ensure that you have installed Docker (with Docker Compose ) and that the Docker daemon is running.

1. Clone the repository

git clone [email protected]:sdslabs/studyportal-nexus.git

2. Setup and start docker containers

docker-compose -f docker-compose-dev.yml up

After executing docker-compose -f docker-compose-dev.yml up, you will be running:

• A Django API server
• PostgreSQL instance(serves as the application database)
• Elasticsearch instance
• Redis server

Once everything has initialized, with docker-compose still running in the background, load the sample data. You will need to install PostgreSQL client tools to perform this step. On Debian, the package is called postgresql-client-common.

./ingest.sh

You are now ready to start sending the API server requests. Hit the API with a request to make sure it is working: curl localhost:8005/api/v1/departments

Diagnosing local Elasticsearch issues

If the API server container failed to start, there's a good chance that Elasticsearch failed to start on your machine. Ensure that you have allocated enough memory to Docker applications, otherwise the container will instantly exit with an error. Also, if the logs mention "insufficient max map count", increase the number of open files allowed on your system. For most Linux machines, you can fix this by adding the following line to /etc/sysctl.conf:

vm.max_map_count = 262144

To make this setting take effect, run:

sudo sysctl -p

Alternate Setup Instructions

You can setup the local dev in a virtualenv:

1. Create a virtualenv using your preferred method.

• Using virtualenv

virtualenv -p python3 venv
source venv/bin/activate

• Using virtualenvwrapper

mkvirtualenv studyportal
workon studyportal

2. Install packages in virtual environment.

pip install -r requirements.txt

3. Edit the .env file.

DATABASE_HOST=localhost
ELASTICSEARCH_HOST=localhost
REDIS_HOST=localhost

4. Initialize the database and create elasticsearch index

python manage.py makemigrations
python manage.py migrate
python manage.py search_index --rebuild -f

5. Create Django admin user

python manage.py createsuperuser

6. Run development server

python manage.py runserver 0.0.0.0:8005
