Flask-Roles
=======================================

Flask-Roles is a flask extensions that adds role access control support.



Installation
===============
Installing the client is simple with pip:

.. code-block:: sh

    pip install flask-roles


Running Tests
===============

.. code-block:: sh

    # tox -e check
    # tox



Docs
===============

You may access the `docs`_ 

.. _docs: https://flask-roles.readthedocs.io/en/latest/

Or build them locally

.. code-block:: sh

    # tox -e docs



Proof of Concept
==================

After installing the client, Use the mixins to enrich your sqlalchemy classes, initialise flask-login and flask-principal. 
For each resource that needs role protection, define a roleneed and decorate the resource.

Start the example:

.. code-block:: sh

  # export PYTHONPATH=$(pwd)
  # cd example
  # ../.tox/py37/bin/python app.py  ## assumes you have run tox before


An anonymouse user has no access to pages which require login or have a role protection
