Error reporting via e-mail
|
|
==========================
|
|
|
|
When you're running a public site you should always turn off the
|
|
:setting:`DEBUG` setting. That will make your server run much faster, and will
|
|
also prevent malicious users from seeing details of your application that can be
|
|
revealed by the error pages.
|
|
|
|
However, running with :setting:`DEBUG` set to ``False`` means you'll never see
|
|
errors generated by your site -- everyone will just see your public error pages.
|
|
You need to keep track of errors that occur in deployed sites, so Django can be
|
|
configured to email you details of those errors.
|
|
|
|
Server errors
|
|
-------------
|
|
|
|
When :setting:`DEBUG` is ``False``, Django will e-mail the users listed in the
|
|
:setting:`ADMINS` setting whenever your code raises an unhandled exception and
|
|
results in an internal server error (HTTP status code 500). This gives the
|
|
administrators immediate notification of any errors. The :setting:`ADMINS` will
|
|
get a description of the error, a complete Python traceback, and details about
|
|
the HTTP request that caused the error.
|
|
|
|
.. note::
|
|
|
|
In order to send e-mail, Django requires a few settings telling it
|
|
how to connect to your mail server. At the very least, you'll need
|
|
to specify :setting:`EMAIL_HOST` and possibly
|
|
:setting:`EMAIL_HOST_USER` and :setting:`EMAIL_HOST_PASSWORD`,
|
|
though other settings may be also required depending on your mail
|
|
server's configuration. Consult :doc:`the Django settings
|
|
documentation </ref/settings>` for a full list of email-related
|
|
settings.
|
|
|
|
By default, Django will send email from root@localhost. However, some mail
|
|
providers reject all email from this address. To use a different sender
|
|
address, modify the :setting:`SERVER_EMAIL` setting.
|
|
|
|
To disable this behavior, just remove all entries from the :setting:`ADMINS`
|
|
setting.
|
|
|
|
404 errors
|
|
----------
|
|
|
|
Django can also be configured to email errors about broken links (404 "page
|
|
not found" errors). Django sends emails about 404 errors when:
|
|
|
|
* :setting:`DEBUG` is ``False``
|
|
|
|
* :setting:`SEND_BROKEN_LINK_EMAILS` is ``True``
|
|
|
|
* Your :setting:`MIDDLEWARE_CLASSES` setting includes ``CommonMiddleware``
|
|
(which it does by default).
|
|
|
|
If those conditions are met, Django will e-mail the users listed in the
|
|
:setting:`MANAGERS` setting whenever your code raises a 404 and the request has
|
|
a referer. (It doesn't bother to e-mail for 404s that don't have a referer --
|
|
those are usually just people typing in broken URLs or broken web 'bots).
|
|
|
|
You can tell Django to stop reporting particular 404s by tweaking the
|
|
:setting:`IGNORABLE_404_ENDS` and :setting:`IGNORABLE_404_STARTS` settings. Both
|
|
should be a tuple of strings. For example::
|
|
|
|
IGNORABLE_404_ENDS = ('.php', '.cgi')
|
|
IGNORABLE_404_STARTS = ('/phpmyadmin/',)
|
|
|
|
In this example, a 404 to any URL ending with ``.php`` or ``.cgi`` will *not* be
|
|
reported. Neither will any URL starting with ``/phpmyadmin/``.
|
|
|
|
The best way to disable this behavior is to set
|
|
:setting:`SEND_BROKEN_LINK_EMAILS` to ``False``.
|
|
|
|
.. seealso::
|
|
|
|
You can also set up custom error reporting by writing a custom piece of
|
|
:ref:`exception middleware <exception-middleware>`. If you do write custom
|
|
error handling, it's a good idea to emulate Django's built-in error handling
|
|
and only report/log errors if :setting:`DEBUG` is ``False``.
