asyncio REST API Resource database

Project Description

Please read the detailed docs

This is the working project of the next generation Guillotina server based on asyncio.

Dependencies

  • python >= 3.6
  • postgresql >= 9.6

Getting started with development

We use buildout of course:

virtualenv .
./bin/pip install zc.buildout
./bin/buildout

The buildout installs the app itself, code analysis tools, and a test runner.

Run postgresql

If you don’t have a postgresql server to play with, you can run one easily with docker.

In the terminal:

make run-postgres

Run the server

To run the server:

./bin/guillotina

Then…

curl http://localhost:8080

Or, better yet, use postman to start playing with API.

Run tests

We’re using py.test:

./bin/py.test src

and for test coverage:

./bin/py.test --cov=guillotina guillotina/

With file watcher…

./bin/ptw guillotina –runner=./bin/py.test

To run tests with cockroach db:

USE_COCKROACH=true ./bin/pytest guillotina

Default

Default root access can be done with AUTHORIZATION header : Basic root:root
