Test Application

A Django application with Celery task queue integration, using PostgreSQL and RabbitMQ.

Prerequisites

• Conda

Quick Start

1. Clone and Setup Environment

git clone <repository-url>
cd <repository-name>
conda env create -f environment.yml
conda activate test-app

2. Configure Environment Copy the .env.template file to create your .env:

cp .env.template .env

Then modify the values in .env according to your needs.

3. Configure PostgreSQL

# First-time setup
mkdir -p $CONDA_PREFIX/var/{postgres,run/postgresql}
initdb -D $CONDA_PREFIX/var/postgres
echo "unix_socket_directories = '$CONDA_PREFIX/var/run/postgresql'" >> $CONDA_PREFIX/var/postgres/postgresql.conf

# Start PostgreSQL
pg_ctl -D $CONDA_PREFIX/var/postgres start

# Create database and user
export $(cat .env | grep -v '^#' | xargs)
createdb -h $CONDA_PREFIX/var/run/postgresql $POSTGRES_DB
psql -h $CONDA_PREFIX/var/run/postgresql -d $POSTGRES_DB << EOF
CREATE USER $POSTGRES_USER WITH PASSWORD '$POSTGRES_PASSWORD';
ALTER USER $POSTGRES_USER WITH CREATEDB;
GRANT ALL PRIVILEGES ON DATABASE $POSTGRES_DB TO $POSTGRES_USER;
GRANT ALL ON SCHEMA public TO $POSTGRES_USER;
ALTER SCHEMA public OWNER TO $POSTGRES_USER;
EOF

4. Run the Application In separate terminals (with conda activate test-app):

# Terminal 1: RabbitMQ
rabbitmq-server

# Terminal 2: Django
python manage.py migrate
python manage.py runserver

# Terminal 3: Celery
celery -A app worker -l INFO -c 1

Access the application:

• Django: http://localhost:8000
• RabbitMQ Management: http://localhost:15672 (guest/guest)
