Project description

flake8-flask

flake8-flask is a plugin for flake8 with checks specifically for the flask framework.

Installation

3.7.9 (mccabe: 0.6.1, need-filename-or-mimetype-for-file-objects-in-send-file: 0.0.7, pycodestyle: 2.5.0, pyflakes: 2.1.1, secure-set-cookie: 0.0.2)

List of warnings

R2C202: need-filename-or-mimetype-for-file-objects-in-send-file: This check detects the use of a file-like object in flask.send_file without either mimetype or attachment_filename keyword arguments. send_file will throw a ValueError in this situation.

R2C203: secure-set-cookie: This check detects calls to response.set_cookie that do not have secure, httponly, and samesite set. This follows the guidance in the Flask documentation.
