Sets up a sane/reasonable Rollbar configuration for Flask apps, based upon Rollbar's suggestions and personal experience. Ignores some 400-level exceptions by default but can be customized.

Flask-Rollbar expects there to be two values defined on the Flask app's config: ROLLBAR_TOKEN and ROLLBAR_ENV. The ROLLBAR_TOKEN is your app's server-side POST token, and the environment is the Rollbar environment to which your events will be posted. Flask-Rollbar defaults to an environment of "dev".

Here's a quick example of initializing this plugin in:

from flask import Flask
from flask.ext.rollbar import Rollbar

app = Flask(__name__)
app.config['ROLLBAR_TOKEN'] = 'mytoken'
app.config['ROLLBAR_ENV'] = 'testing'

Rollbar(app)

@app.route('/')
def this_will_fail():
    1/0

Customizing ignored exceptions:

from werkzeug.exceptions import Unauthorized, Forbidden, NotFound

ignored = [Unauthorized, Forbidden, NotFound]
Rollbar(app, ignore_exc=ignored)
