Project Setup

Create a .env file from a provided example (dotenv) and update its variables

cp dotenv .env

Start docker stack:

docker-compose up -d

Enter docker container (app):

docker exec -it predico_rest_app bash

Inside the container (predico_rest_app) apply current migrations and create superuser.

python manage.py migrate
python manage.py createsuperuser

Run collectstatic to serve static files

python manage.py collectstatic

Check if all tests pass successfully

pytest

See the Swagger (http://0.0.0.0:80/swagger) for methods description.

How to easy deploy in "debug" mode (developers)?

How to run the code in development mode, with APP decoupled from docker stack?

First, install the necessary project python dependencies:

cd /api
poetry install
poetry shell

Then, create a .dev.env file with environment variables used to debug and update default environment variables to your specifics.

Important: Make sure you force develop mode by using the following environment variable DJANGO_APPLICATION_ENVIRONMENT=develop and POSTGRES_HOST=localhost

Then, use docker-compose to initialize a Postgres DB:

docker-compose up -d --build postgresql

Once your DB is up, you can debug locally by just by uncommenting the following lines in "environment.lines:

from dotenv import load_dotenv
load_dotenv(".dev.env")

After this, you can easily run your application without docker container, in either an IDE or straight from the command line.

  1. Migrate your DB migrations:
python manage.py migrate
  1. Create a superuser:
python manage.py createsuperuser
  1. Run your app using through Django runserver command:
python manage.py runserver

Example of a Market Configuration Pipeline:

Important: This is only for administrators

  1. Login with superuser (market admin) ( POST /api/token)
  2. Register a market wallet address ( POST /api/market/wallet-address)
    • Note1: this market address will be used by external users to make crypto transfers during bid placement phase
    • Note2: this address can be updated via REST too ( PUT /api/market/wallet-address)

Example of a Market Session Pipeline:

  1. Login with superuser (market admin) ( POST /api/token)
  2. Create a new market session ( POST /api/market/session):
    • Note: Once created, market sessions are set to a "staged" status.
  3. Update market session status to 'open' to unlock bid placement phase ( PATCH /api/market/session/<market_session_id>)
    • Important: Bids can only be placed once session is on open status
  4. Users can now place their bids. Market Engine (predico-market repository) will validate each bids and update its status via ( POST /api/market/validate/bid-payment)
  5. Once gate closure time is reached (scheduled time) - Market admin changes market session status to 'running' ( PATCH /api/market/session/<market_session_id>)
  6. Market Runs & new session is staged automatically (which will be opened in a scheduled bases later on, for bid acceptance)

Example of a User Configuration Pipeline:

  1. Register (POST /api/user/register) - save verificatio_link 1.1. Validate user (perform GET request to verification_link url to validate user)
  2. Login ( POST /api/token )
  3. Register wallet address (used as reference for token transfers from market to user)
    • Note: this address can be updated via REST too ( PUT /api/user/wallet-address)
  4. Register a user resource (e.g. a wind farm under user portfolio) ( POST /api/user/resource)
    • Note: this resource can be updated via REST too ( PATCH /api/user/resource/<resource_id>)

Example of a User Market Participation Pipeline:

  1. Users can send measurements data to the market ( POST /api/data/raw-data)

    • This data can also be accessed via REST ( GET /api/data/raw-data)
    • Note: Users should continuously send measurements for their resources to maximize their participation in the market (seller role is obligatory for all users)
  2. Once a market session is on 'open' status, users can place their bids. A bid pipeline should be the following:

    • See market session details ( GET /api/market/session) and search for last open session
    • Get market wallet address ( GET /api/market/wallet-address)
    • Make crypto transfer to market wallet address and save transfer message identifier (e.g., DLT transaction identifier)
    • Post bid details ( POST /api/market/bid/)
    • Associate a IOTA tangle message identifier to a specific bid ID in url para ( PATCH /api/market/bid/:bid_id)
  3. Users can check their bids & bid status (if is confirmed or not by market engine) ( GET /api/market/bid/)

  4. At each market run, forecasts will be produced for resources with bids. These forecasts are accessible via REST (GET /api/data/market-forecasts)
