Scalable service for storing SDX data (backed by PostgreSQL).

A running instance of PostgreSQL.

This application presently installs required packages from requirements files:

• requirements.txt: packages for the application, with hashes for all packages: see https://pypi.org/project/hashin/
• test-requirements.txt: packages for testing and linting

It's also best to use pyenv and pyenv-virtualenv, to build in a virtual environment with the currently recommended version of Python. To install these, see:

• https://github.com/pyenv/pyenv
• https://github.com/pyenv/pyenv-virtualenv
• (Note that the homebrew version of pyenv is easiest to install, but can lag behind the latest release of Python.)

Once your virtual environment is set, install the requirements:

$ make build

To test, first run make build as above, then run:

$ make test

It's also possible to install within a container using docker. From the sdx-store directory:

$ docker build -t sdx-store .

Start the sdx-store service using the following command:

$ python server.py

There are seven endpoints:

• GET /invalid-responses - returns a json response of all invalid survey responses in the connected database
• POST /queue - Publishes a message to a corresponding rabbit message queue based on the message content. Returns a 200 response and JSON value {"result": "ok"} if the publish succeeds or a 500 response with JSON value {"status": 500, "message": <error>} if it does not.
• GET /healthcheck - returns a json response with key/value pairs describing the service state
• POST /responses - store a json survey response
• GET /responses - retrieve a JSON response of all valid survey responses in the connected responses.
• GET /responses/<tx_id> - retrieve a survey by id
• DELETE /responses/old - delete responses older than a number of days set in config
• GET /feedback/<feedback_ID> - retrieve a JSON response of a valid ID

The /responses , /invalid-responses and /feedback endpoints support paging using URL query parameters.

• per_page: The number of responses to return per page. Must be in the range 1-100. Defaults to 1.
• page: The page number to return. Must be 1 or higher if set. Defaults to 1.
