Mongoengine flask connect via uri

Hi, I have a small flash drive app that I am deploying to a hero.

My local configuration is as follows:

from flask import Flask
from flask.ext.mongoengine import MongoEngine

app = Flask(__name__)
app.debug = True
app.config["MONGODB_SETTINGS"] = {'DB': "my_app"}
app.config["SECRET_KEY"] = "secretpassword"

db = MongoEngine(app)

So, I know that I need to configure the application to use the mongo connection method URI, and I have connection information:

mongodb://<user>:<password>@alex.mongohq.com:10043/app12345678

I'm just a little fixated on the syntax for modifying my application to connect through URI.

Any help would be greatly appreciated.

So I got the job (finally):

from flask import Flask
from mongoengine import connect

app = Flask(__name__)

app.config["MONGODB_DB"] = 'app12345678'
connect(
    'app12345678',
    username='heroku',
    password='a614e68b445d0d9d1c375740781073b4',
    host='mongodb://<user>:<password>@alex.mongohq.com:10043/app12345678',
    port=10043
)

Although I expect various other configurations to work.

Using the introspection of the python nifty object (python oh, as I love you), you can see how the MongoEngine shell class does this:

from flask.ext.mongoengine import MongoEngine
import inspect
print(inspect.getsource(MongoEngine))
    ...
    conn_settings = {
        'db': app.config.get('MONGODB_DB', None),
        'username': app.config.get('MONGODB_USERNAME', None),
        'password': app.config.get('MONGODB_PASSWORD', None),
        'host': app.config.get('MONGODB_HOST', None),
        'port': int(app.config.get('MONGODB_PORT', 0)) or None
    }
     ...
     self.connection = mongoengine.connect(**conn_settings)
     ...
     self.app = app
