financeager-flask 1.1.0

Plugin to use flask as backend for financeager

financeager-flask

Plugin that enables you to run financeager as a Flask-powered webservice!

Installation

financeager-flask requires Python 3.8 or higher.

pip install financeager-flask

Installation via pipx is recommended:

pipx install financeager
pipx inject financeager financeager-flask

Usage

To run financeager as client-server application, start the flask webservice by

export FLASK_APP=financeager_flask.flask
flask run  # --help for more info

This does not store data persistently! Specify the environment variable FINANCEAGER_FLASK_DATA_DIR.

For production use, you should wrap app = flask.create_app(data_dir=...) in a WSGI or FCGI (see examples/ directory).

To communicate with the webservice, the financeager configuration has to be adjusted. Create and open the file ~/.config/financeager/config. If you're on the machine that runs the webservice, put the lines

[SERVICE]
name = flask

If you're on an actual remote 'client' machine, put

[SERVICE]
name = flask

[SERVICE:FLASK]
host = https://foo.pythonanywhere.com
timeout = 10
username = foouser
password = S3cr3t

This specifies the timeout for HTTP requests and username/password for basic auth, if required by the server.

In any case, you're all set up! The available client CLI commands and options are the same as for the native program.

Command-line options

The plugin provides the fina web-version command, yielding information about the financeager software version installed on the server.

More Goodies

• financeager will store requests if the server is not reachable (the timeout is configurable). The offline backup is restored the next time a connection is established.

Testing

Please adhere to test-driven development, if possible: When adding a feature, or fixing a bug, try to construct a test first, and subsequently adapt the implementation. Run the tests from the root directory via

make test

If you added a non-cosmetic change (i.e. a change in functionality, e.g. a bug fix or a new feature), please update Changelog.md accordingly as well. Check this README whether the content is still up to date.

Releasing

1. Tag the latest commit on master by incrementing the current version accordingly (scheme v0.major.minor.patch).
2. Run make release.
