Connect to MySQL using a connection string

[idarous]

Hello I'm deploying my application on heroku using ClearDB MySQL.

This platform provides the connection string to the database on an environment variable named CLEARDB_DATABASE_URL that contains a value like that

mysql://username:password@host/databasename?reconnect=true

Is it possible to use directly this string in order to connect my Flask application to this MySQL database without creating a script that parse this string ?

I know that I can specify the configuration like that

from flask import Flask
from flaskext.mysql import MySQL

app = Flask(__name__)
app.config['MYSQL_DATABASE_USER'] = 'username'
app.config['MYSQL_DATABASE_PASSWORD'] = 'password'
app.config['MYSQL_DATABASE_DB'] = 'databasename'
app.config['MYSQL_DATABASE_HOST'] = 'host'
mysql = MySQL()
mysql.init_app(app)

but it will be better for me to be able to specify the configuration like that

from flask import Flask
from flaskext.mysql import MySQL
import os

app = Flask(__name__)
app.config['CONNECTION_STRING'] = os.environ['CLEARDB_DATABASE_URL']
mysql = MySQL()
mysql.init_app(app)

Is it possible to do something like that?
