Project description
Canonical Webteam Flask-Base
Flask extension that applies common configurations to all of webteam's flask apps.
Usage
from canonicalwebteam.flask_base.app import FlaskBase
app = FlaskBase(__name__, "app.name")
Or:
from canonicalwebteam.flask_base.app import FlaskBase
app = FlaskBase(
__name__,
"app.name",
template_404="404.html",
template_500="500.html",
favicon_url="/static/favicon.ico",
)
Features
Redirects and deleted paths
FlaskBase uses yaml-responses to allow easy configuration of redirects and return of deleted responses, by creating redirects.yaml, permanent-redirects.yaml and deleted.yaml in the site root directory.
Error templates
FlaskBase can optionally use templates to generate the 404 and 500 error responses:
app = FlaskBase(
__name__,
"app.name",
template_404="404.html",
template_500="500.html",
)
This will lead to e.g. http://localhost/non-existent-path returning a 404 status with the contents of templates/404.html.
Redirect /favicon.ico
FlaskBase can optionally provide redirects for the commonly queried paths /favicon.ico, /robots.txt and /humans.txt to sensible locations:
from canonicalwebteam.flask_base.app import FlaskBase
app = FlaskBase(
__name__,
"app.name",
template_404="404.html",
template_500="500.html",
favicon_url="/static/favicon.ico",
robots_url="/static/robots.txt",
humans_url="/static/humans.txt"
)
This will lead to e.g. http://localhost/favicon.ico returning a 302 redirect to http://localhost/static/favicon.ico.
Jinja2 helpers
You get two jinja2 helpers to use in your templates from flask-base:
nowis a function that outputs the current date in the passed format -{{ now('%Y') }}->YYYYversioned_staticis a function that fingerprints the passed asset -{{ versioned_static('asset.js') }}->static/asset?v=asset-hash
robots.txt and humans.txt
If you create a robots.txt or humans.txt in the root of your project, these will be served at /robots.txt and /humans.txt respectively.
Generating setup.py
In this project, for the time being, we maintain both a pyproject.toml for Poetry and a setup.py for traditional Python tooling. If you are developing on the module, you should update pyproject.toml first and then regenerate the setup.py using:
poetry install
poetry run poetry-setup
Tests
To run the tests execute poetry run python -m unittest discover tests.
