UCSD Oasis platform

Local project setup

1. Install Docker Compose and make sure you have Pip installed
2. Clone the project and go to the project folder in your console
3. Run ./dev-setup to build the project
   • Tip: Make sure to run this command regularly, or at least, every time you start something fresh from master!
4. To run the app: docker-compose up - navigate to http://localhost:3000 to see it! 🚀
   • All API endpoints are available in http://localhost:8000/api/{endpoint-name-here}

Adding packages to the frontend

If you need to add packages to the frontend app, make sure to do so with yarn and within the docker environment:

docker-compose run --rm ui yarn add PACKAGE_NAME_HERE 

Creating new backend apps with models

If you're creating an app on the backend and it contains models, you'll need to set up a couple of things to make sure migrations work. To begin with, in your app's models.py make sure to import the app's declarative base and creating your models based off that:

from database import Base

class YourCoolModel(Base):
    __tablename__ = "super_cool_models"
    id = Column(Integer, primary_key=True, index=True)
    # all your cool model attributes go here

After that, head over to alembic.env and import your models on the top section of the file:

from users import models
from yourcoolapp import models

That's about it! Migrations should auto-generate correctly with that set up!

Generating & running migrations

As part of our everyday work, data models may change from time to time. When you change a model in the backend, make sure to run the following code to generate any necessary Alembic migrations:

docker-compose run --rm api alembic revision --autogenerate -m "Migration name here!"

When possible, keep the migration name descriptive!

When a new migration file is available, apply it by running

./dev-setup.sh

If you want to run them manually you can also do:

docker-compose run --rm api alembic upgrade head

You can also roll back migrations by doing

docker-compose run --rm api alembic downgrade -1

Seeding data

To populate development database with seed data, which is located in /backend/almebic/seed_data directory, run:

docker-compose run --rm api python alembic/seed.py

To add seed data or modify existing one, apply changes in <entity>.json file for the target entity in aforementioned /backend/alembic/seed_data directory. Make sure that the script uses the data you are interested in, by checking the "files to be imported" at the top of the script.

Running backend tests

All tests for the backed are within the /backend/tests folder, and they're run automatically on branches and PRs by Travis. You can run them by doing:

docker-compose run --rm -e DATABASE_NAME='dbtest' api pytest

Building & deploying

Builds are generated automatically whenever we:

• Push to master (updates the dev image)
• Push to a branch named release/something (updates an image called release/something-dev)
• Tag the project (generates a tag-name image)

After doing any of these actions, you can head over to Travis to see how the build is faring.

With the build ready, head over to Rancher to upgrade the Oasis instances in the environment you need to deploy to.

Make sure to:

1. first upgrade the db-migration container if there is any new migration,
2. then the app container adding any necessary environment variables
