Deployment
----------

This application can be deployed on Heroku or on a traditional server.

After installation, you will be able to connect with the email *root@pyAggr3g470r.localhost* and the password *password*.


Deploying the application on Heroku
'''''''''''''''''''''''''''''''''''

An instance of pyAggr3g470r is running `here <https://pyaggr3g470r.herokuapp.com/>`_.

.. code:: bash

    $ git clone https://bitbucket.org/cedricbonhomme/pyaggr3g470r.git
    $ cd pyaggr3g470r
    $ heroku create
    $ heroku addons:add heroku-postgresql:dev
    $ heroku config:set HEROKU=1
    $ git push heroku master
    $ heroku run init
    $ heroku ps:scale web=1

To enable account creation for users, you have to set some environment variables:

.. code:: bash

    $ heroku config:set PLATFORM_URL=<URL-of-your-platform>
    $ heroku config:set RECAPTCHA_PUBLIC_KEY=<your-recaptcha-public-key>
    $ heroku config:set RECAPTCHA_PRIVATE_KEY=<your-recaptcha-private-key>
    $ heroku config:set NOTIFICATION_EMAIL=<notification-email>
    $ heroku addons:add postmark:10k

`Postmark <https://postmarkapp.com/>`_ is used to send account confirmation links.

If you don't want to open your platform you will be still able to create accounts via the administration page.

Alternatively, you can deploy your own copy of the app using this button:

Deploying the application on a traditional server
'''''''''''''''''''''''''''''''''''''''''''''''''

.. code:: bash

    $ git clone https://bitbucket.org/cedricbonhomme/pyaggr3g470r.git
    $ cd pyaggr3g470r
    $ sudo apt-get install libxml2-dev libxslt1-dev
    $ sudo pip install --upgrade -r requirements.txt
    $ cp conf/conf.cfg-sample conf/conf.cfg

If you want to use PostgreSQL
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. code:: bash

    $ sudo apt-get install postgresql postgresql-server-dev-9.3 postgresql-client
    $ sudo -u postgres createuser
    Enter name of role to add: username
    Shall the new role be a superuser? (y/n) n
    Shall the new role be allowed to create databases? (y/n) y
    Shall the new role be allowed to create more new roles? (y/n) n
    $ createdb pyAggr3g470r
    $ sudo -u postgres psql
    postgres=# ALTER USER username WITH ENCRYPTED PASSWORD 'password';
    postgres=# GRANT ALL PRIVILEGES ON DATABASE pyAggr3g470r TO username;
    postgres=# \q

Edit the configuration file with the line:

.. code:: cfg

    [database]
    uri = postgres://username:password@127.0.0.1:5433/pyAggr3g470r

If you want to use SQLite
~~~~~~~~~~~~~~~~~~~~~~~~~

Just edit the configuration file with the line:

.. code:: cfg

    [database]
    uri = sqlite+pysqlite:///pyAggr3g470r.db


Finally:

.. code:: bash

    $ python db_create.py
    $ python runserver.py
     * Running on http://0.0.0.0:5000/
     * Restarting with reloader


Configuration
-------------

Configuration (database url, email, proxy, user agent, etc.) is done via the file *conf/conf.cfg*.
Check these configuration before executing *db_create.py*.   
If you want to use pyAggr3g470r with Tor/Privoxy, you just have to set the value of
*http_proxy* (most of the time: *http_proxy = 127.0.0.1:8118**). Else leave the value blank.


Automatic updates
-----------------

You can fetch new articles with `cron <https://en.wikipedia.org/wiki/Cron>`_  and the script *fetch.py*.
For example if you want to check for updates every 30 minutes, add this line to your cron rules (*crontab -e*):

.. code:: bash

    */30 * * * * cd ~/.pyaggr3g470r/ ; python fetch.py firstname.lastname@mail.com

You must give the email address you use to login to pyAggr3g470r.
