Installing Dependencies

This project uses Django 2.2 that requires Python 3

1. Install Python 3:

brew install python3

2. Install virtualenv and virtualenvwrapper

pip3 install virtualenv virtualenvwrapper
echo "source /usr/local/bin/virtualenvwrapper.sh" >> ~/.bashrc
exec bash

3. Install Sentry's command line tool to use release tracking and Github integration for commit data:

npm install -g @sentry/cli

This demo uses npm, pip, and virtualenv.

Configuring Sentry

The Sentry client library requires a DSN generated from Sentry which specifies the project events will be sent to. Add the import and configuration code to settings.py:

import sentry_sdk
from sentry_sdk.integrations.django import DjangoIntegration

sentry_sdk.init(
   dsn="https://[email protected]/1234567"
)

Further details on configuring Sentry here.

Running The Demo

Virtualenv setup

Setup and activate a Python 3 virtual environment in the project root:

mkvirtualenv --python=python3 sentry-demo-django

To use virtualenv:

workon sentry-demo-django

Runing Django

make deploy

Demo Specs

This demo uses Django's rest-framework package and offers 3 API endpoints:

1. http://localhost:8000/handled - generates a runtime error excplicitly reported to Sentry though the SDk's captureException
2. http://localhost:8000/unhandled - generates an unhandled runtime error reported
3. http://localhost:8000/checkout - can be used with the Sentry REACT demo store front demo This endpoint can also be used with directly through the Django REST Framework web UI. To generate an error paste the following JSON payload in the POST payload text area:

    {
    "cart": [
        {"id": "wrench", "name": "Wrench", "price": 500},
        {"id": "wrench", "name": "Wrench", "price": 500}
    ],
    "email": "[email protected]"
    }

Cleaning Up
