Honeybadger for Python

Source Code

Getting Started

Honeybadger for Python works out of the box with Django with only a few configuration options required. The following is a basic setup - more advanced setup will be described later.

Install Honeybadger

Install honeybadger with pip.

$ pip install honeybadger


NOTE: Middleware configuration has changed in Django 1.10. Instead of using MIDDLEWARE_CLASSES, simply use the MIDDLEWARE configuration instead.

In a Django application, add the Honeybadger Django middleware to the top of your MIDDLEWARE_CLASSES config variable:


It's important that the Honeybadger middleware is at the top, so that it wraps the entire request process, including all other middlewares.

You'll also need to add a new HONEYBADGER config variable to your settings.py to specify your API key:

  'API_KEY': 'myapikey'

Other frameworks / plain Python app

Django is the only explicitly supported framework at the moment. For other frameworks (Flask, web2py, etc.) or a plain Python script, simply import honeybadger and configure it with your API key. Honeybadger uses a global exception hook to automatically report any uncaught exceptions.

from honeybadger import honeybadger

raise Exception, "This will get reported!"

All set!

That's it! For additional configuration options, keep reading.


To set configuration options, use the honeybadger.configure method, like so:

honeybadger.configure(api_key='your api key', environment='production')

All of Honeybadger's configuration options can also be set via environment variables with the HONEYBADGER prefix (12-factor style). For example, the api_key option can be set via the HONEYBADGER_API_KEY environment variable.

The following options are available to you:

Name Type Default Example Environment variable
api_key str "" "badgers" HONEYBADGER_API_KEY
project_root str The current working directory "/path/to/project" HONEYBADGER_PROJECT_ROOT
environment str "production" "staging" HONEYBADGER_ENVIRONMENT
hostname str The hostname of the current server. "badger01" HONEYBADGER_HOSTNAME
endpoint str "https://api.honeybadger.io" "https://honeybadger.example.com/" HONEYBADGER_ENDPOINT
params_filters list ['password', 'password_confirmation', 'credit_card'] ['super', 'secret', 'keys'] HONEYBADGER_PARAMS_FILTERS


By default, Honeybadger uses the logging.NullHandler for logging so it doesn't make any assumptions about your logging setup. In Django, add a honeybadger section to your LOGGING config to enable Honeybadger logging. For example:

    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'file': {
            'level': 'DEBUG',
            'class': 'logging.FileHandler',
            'filename': '/path/to/django/debug.log',
    'loggers': {
        'honeybadger': {
            'handlers': ['file'],
            'level': 'DEBUG',
            'propagate': True,

For other frameworks or a plain Python script, you can use logging.dictConfig or explicitly configure it like so:

import logging

Public Methods

honeybadger.set_context: Set global context data

This method allows you to send additional information to the Honeybadger API to assist in debugging. This method sets global context data and is additive - eg. every time you call it, it adds to the existing set unless you call reset_context, documented below.


from honeybadger import honeybadger

honeybadger.reset_context: Clear global context data

This method clears the global context dictionary.


from honeybadger import honeybadger

honeybadger.context: Python context manager interface

What if you don't want to set global context data? You can use Python context managers to set case-specific contextual information.


# from a Django view
from honeybadger import honeybadger
def my_view(request):
  with honeybadger.context(user_email=request.POST.get('user_email', None)):
    form = UserForm(request.POST)

honeybadger.configure: Specify additional configuration options

Allows you to configure honeybadger within your code. Accepts any of the above-listed configuration options as keyword arguments.


honeybadger.configure(api_key='myapikey', project_root='/home/dave/crywolf-django')

honeybadger.notify: Send an error notice to Honeybadger

In cases where you'd like to manually send error notices to Honeybadger, this is what you're looking for. You can either pass it an exception as the first argument, or an error_class/error_message pair of keyword arguments. You can also pass it a custom context dictionary which will get merged with the global context.


# with an exception
mydict = dict(a=1)
  print mydict['b']
except KeyError, exc:
  honeybadger.notify(exc, context={'foo': 'bar'})

# with custom arguments
honeybadger.notify(error_class='ValueError', error_message='Something bad happened!')

Supported Versions

Tested with Django 1.9 and 1.10 and Python 2.7 through 3.5. Django integration is done via middleware and will work out of the box up to version 1.10.
