ratchet 0.4.1

Ratchet.io generic python library

pyratchet is a generic library for reporting exceptions and other messages to Ratchet.io:

import ratchet, sys
ratchet.init('YOUR_ACCESS_TOKEN', 'production')  # access_token, environment

try:
    main_app_loop()
except IOError:
    ratchet.report_message('Got an IOError in the main loop', 'warning')
except:
    # catch-all
    ratchet.report_exc_info(sys.exc_info())

Requirements

pyratchet requires:

  • Python 2.6 or 2.7
  • requests 0.12+
  • a Ratchet.io account

Installation

Install using pip:

pip install ratchet

Configuration

For generic Python or a non-Django/non-Pyramid framework, follow these instructions:

Somewhere in your initialization code, call ratchet.init() with your access_token:

ratchet.init('YOUR_ACCESS_TOKEN_HERE', environment='production')

Other options can be passed as keyword arguments. See the reference below for all options.

If you are integrating with Django, follow these instructions:

  1. In your settings.py, add 'ratchet.contrib.django.middleware.RatchetNotifierMiddleware' as the last item in MIDDLEWARE_CLASSES:

    MIDDLEWARE_CLASSES = (
        # ... other middleware classes ...
        'ratchet.contrib.django.middleware.RatchetNotifierMiddleware',
    )
    
  2. Add these configuration variables in settings.py:

    RATCHET = {
        'access_token': 'YOUR_ACCESS_TOKEN_HERE',
        'environment': 'development' if DEBUG else 'production',
        'branch': 'master',
        'root': '/absolute/path/to/code/root',
    }
    

If you are integrating with Pyramid, follow these instructions:

  1. In your ini file (e.g. production.ini), add ratchet.contrib.pyramid to the end of your pyramid.includes:

    [app:main]
    pyramid.includes =
        pyramid_debugtoolbar
        ratchet.contrib.pyramid
    
  2. Add these ratchet configuration variables:

    [app:main]
    ratchet.access_token = YOUR_ACCESS_TOKEN_HERE
    ratchet.environment = production
    ratchet.branch = master
    ratchet.root = %(here)s
    

The above will configure ratchet to catch and report all exceptions that occur in your Pyramid app. However, if there are any middleware applications that wrap your app, Ratchet will not be able to catch exceptions.

In order to catch exceptions from Pyramid and middleware code, you will need to create a pipeline where the ratchet middleware wraps your Pyramid app.

  • Change your ini file to use a pipeline:

    From
    
    [app:main]
    ...
    
    To
    
    [pipeline:main]
    pipeline =
        ratchet
        YOUR_APP_NAME
    
    [app:YOUR_APP_NAME]
    pyramid.includes =
        pyramid_debugtoolbar
        ratchet.contrib.pyramid
    
    [filter:ratchet]
    access_token = YOUR_ACCESS_TOKEN_HERE
    environment = production
    branch = master
    root = %(here)s
    

Unfortunately, the ratchet tween and the ratchet filter configurations contains duplicated information. We'll look into fixing this in future versions.

Usage

The Django and Pyramid integration will automatically report uncaught exceptions to Ratchet.

Call ratchet.report_exc_info() to report an exception, or ratchet.report_message() to report an arbitrary string message. See the docstrings for more info.

Configuration reference

access_token
Access token from your Ratchet.io project
handler

One of:

  • blocking -- runs in main thread
  • thread -- spawns a new thread
  • agent -- writes messages to a log file for consumption by ratchet-agent

default: thread

environment
Environment name. Any string up to 255 chars is OK. For best results, use "production" for your production environment.
root
Absolute path to the root of your application, not including the final /.
branch

Name of the checked-out branch.

default: master

agent.log_file
If handler is agent, the path to the log file. Filename must end in .ratchet
endpoint

URL items are posted to.

default: https://submit.ratchet.io/api/1/item/

scrub_fields

List of field names to scrub out of POST. Values will be replaced with astrickses. If overridiing, make sure to list all fields you want to scrub, not just fields you want to add to the default. Param names are converted to lowercase before comparing against the scrub list.

default ['passwd', 'password', 'secret', 'confirm_password', 'password_confirmation']
