Library for Django that provides better error logging

Project description


django-better500s is a library that makes 500 errors more
user-friendly, and more developer-friendly. It logs the full error
traceback (as if it were in DEBUG mode), as well as a user's
description of what they were trying to do.

Pull requests are quite welcome!


## Installation ##

1. `pip install django-better500s`

2. Edit your ``

INSTALLED_APPS += ("better500s",)

# If you have other exception-processing middleware, you should
# pay attention to what order you put middleware in. "At the end"
# should work fine for Better500s, though.
MIDDLEWARE_CLASSES += ("better500s.middleware.Better500s",)

# Set any optional settings (below)
BETTER_500_LOG_DIR = join(PROJECT_ROOT, 'logs', 'better_500')
BETTER_500_TO_EMAILS = ["",]
BETTER_500_UNCAUGHT_DIR = "Uncaught Logs"


4. Add in the urls:

urlpatterns += patterns('',
url(r'better500s/', include('better500s.urls', namespace="better500s", app_name='better500s') ),

5. Enjoy better error reports.

### Optional Settings:

* `BETTER_500_LOG_DIR` - Where the full log traces should be stored (on `default_storage`, or failing that, locally).
Defaults to `"PROJECT_ROOT/logs/better500s"`.

* `BETTER_500_FROM_EMAIL` - The email that notifications should be sent from.
Defaults to `settings.DEFAULT_FROM_EMAIL`.

* `BETTER_500_TO_EMAILS` - The set of email that notifications should be sent to.
Defaults to `settings.ADMINS`.

* `BETTER_500_UNCAUGHT_DIR` - Where to store log traces in which the 500 handling page crashed, or the user's browser crashed.
Defaults to `"UNCAUGHT"`.

* `BETTER_500_AJAX_URL` - URL for ajax callback, that saves the log, and sends off an email.
Defaults to `"better-500-callback/"`.

* `BETTER_500_POST_URL` - URL for user crash report posting.
Defaults to `"better-500-saved/"`.

* `BETTER_500_DEFAULT_RETURN_URL_NAME` - The url name that the "Go Home" button should link to. If none, the button is hidden.
Defaults to `None`.

How it works:

1. 500 errors (only) are caught.
2. Full debug page traceback is generated, and saved to the `UNCAUGHT_DIR`.
3. A "We're sorry / Tell us what you were doing" page loads.
4. On load, that page ajax pings the server.
5. On ping, the view files the log into a date-organized folder, and emails the `TO_EMAILs` with a link.
6. If the user submits a report, that report is saved to the database, tied to the log file. A second email is sent, with the user's report.
7. An admin can click the view link, and see the full traceback, and the user's report.

Templates and Customization

### Templates

* `500_handler.html` - This template is what users see when a 500 occurs, and where they can submit their report.

* `feedback_saved.html` - If a user submits a report, this page is what they see. Links to the page that produced the error, and optionally, home.

* `view_error.html` - Developer-side template for viewing captured 500s

* `admin_email.txt` - Template for the 500 error email.

* `error_with_notes_email.txt` - Template for the user bug report email.

### Log file storage

By default, django-better500s uses the `default_backend` to store
error logs. If that fails, it falls back local file storage.

django-better500s was written by Steven Skoczen for Aquameta.
