Usage & API
Setup
Install project dependencies
make poetry
You don't have to install it independently in the project repo, just import pyinfra in any .py-file
or install form another project
poetry add git+ssh://git@git.iqser.com:2222/rr/pyinfra.git#TAG-NUMBER
API
from pyinfra.config import get_config
from pyinfra.payload_processing.processor import make_payload_processor
from pyinfra.queue.queue_manager import QueueManager
queue_manager = QueueManager(get_config())
queue_manager.start_consuming(make_payload_processor(data_processor))
The data_processor should expect a dict or bytes (pdf) as input and should return a list of results.
Scripts
Run pyinfra locally
Shell 1: Start minio and rabbitmq containers
$ cd tests && docker-compose up
Shell 2: Start pyinfra with callback mock
$ python scripts/start_pyinfra.py
Shell 3: Upload dummy content on storage and publish message
$ python scripts/mock_process_request.py
Tests
The tests take a bit longer than you are probably used to, because among other things the required startup times are quite high. The test runtime can be accelerated by setting 'autouse' to 'False'. In that case, run 'docker-compose up' in the tests dir manually before running the tests.
