====== Flask SQLAlchemy ======

For using it with MySQL:
<code>
$ apt-get install python-dev libmysqlclient-dev
$ pip install mysql-python
</code>
Then the connection string will be:
<code>
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://username:password@localhost/db_name'
</code>
It seems that you also can install the pymysql package, then:
<code>
'mysql+pymysql://username:password@localhost/db_name'
</code>
