<p>When you’re running a public site you should always turn off the
<a class="reference internal" href="../ref/settings.html#std:setting-DEBUG"><code class="xref std std-setting docutils literal"><span class="pre">DEBUG</span></code></a> 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.</p>
<p>However, running with <a class="reference internal" href="../ref/settings.html#std:setting-DEBUG"><code class="xref std std-setting docutils literal"><span class="pre">DEBUG</span></code></a> set to <code class="docutils literal"><span class="pre">False</span></code> 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 create reports with details about those errors.</p>

<p class="last">In order to send email, Django requires a few settings telling it
how to connect to your mail server. At the very least, you’ll need
to specify <a class="reference internal" href="../ref/settings.html#std:setting-EMAIL_HOST"><code class="xref std std-setting docutils literal"><span class="pre">EMAIL_HOST</span></code></a> and possibly
<a class="reference internal" href="../ref/settings.html#std:setting-EMAIL_HOST_USER"><code class="xref std std-setting docutils literal"><span class="pre">EMAIL_HOST_USER</span></code></a> and <a class="reference internal" href="../ref/settings.html#std:setting-EMAIL_HOST_PASSWORD"><code class="xref std std-setting docutils literal"><span class="pre">EMAIL_HOST_PASSWORD</span></code></a>,
though other settings may be also required depending on your mail
server’s configuration. Consult <a class="reference internal" href="../ref/settings.html"><span class="doc">the Django settings

</div>
<p>By default, Django will send email from <a class="reference external" href="mailto:root%40localhost">root<span>@</span>localhost</a>. However, some mail

address, modify the <a class="reference internal" href="../ref/settings.html#std:setting-SERVER_EMAIL"><code class="xref std std-setting docutils literal"><span class="pre">SERVER_EMAIL</span></code></a> setting.</p>

<p>Django can also be configured to email errors about broken links (404 “page

<ul class="simple">
<li><a class="reference internal" href="../ref/settings.html#std:setting-DEBUG"><code class="xref std std-setting docutils literal"><span class="pre">DEBUG</span></code></a> is <code class="docutils literal"><span class="pre">False</span></code>;</li>
<li>Your <a class="reference internal" href="../ref/settings.html#std:setting-MIDDLEWARE_CLASSES"><code class="xref std std-setting docutils literal"><span class="pre">MIDDLEWARE_CLASSES</span></code></a> setting includes
<a class="reference internal" href="../ref/middleware.html#django.middleware.common.BrokenLinkEmailsMiddleware" title="django.middleware.common.BrokenLinkEmailsMiddleware"><code class="xref py py-class docutils literal"><span class="pre">django.middleware.common.BrokenLinkEmailsMiddleware</span></code></a>.</li>
</ul>
<p>If those conditions are met, Django will email the users listed in the
<a class="reference internal" href="../ref/settings.html#std:setting-MANAGERS"><code class="xref std std-setting docutils literal"><span class="pre">MANAGERS</span></code></a> setting whenever your code raises a 404 and the request has
a referer. (It doesn’t bother to email for 404s that don’t have a referer –
those are usually just people typing in broken URLs or broken Web ‘bots).</p>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last"><a class="reference internal" href="../ref/middleware.html#django.middleware.common.BrokenLinkEmailsMiddleware" title="django.middleware.common.BrokenLinkEmailsMiddleware"><code class="xref py py-class docutils literal"><span class="pre">BrokenLinkEmailsMiddleware</span></code></a> must appear

</div>
<p>You can tell Django to stop reporting particular 404s by tweaking the
<a class="reference internal" href="../ref/settings.html#std:setting-IGNORABLE_404_URLS"><code class="xref std std-setting docutils literal"><span class="pre">IGNORABLE_404_URLS</span></code></a> setting. It should be a tuple of compiled
regular expression objects. For example:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="kn">import</span> <span class="nn">re</span>
<span class="n">IGNORABLE_404_URLS</span> <span class="o">=</span> <span class="p">(</span>
<span class="n">re</span><span class="o">.</span><span class="n">compile</span><span class="p">(</span><span class="s1">r'\.(php|cgi)$'</span><span class="p">),</span>
<span class="n">re</span><span class="o">.</span><span class="n">compile</span><span class="p">(</span><span class="s1">r'^/phpmyadmin/'</span><span class="p">),</span>
<span class="p">)</span>
</pre></div>
</div>
<p>In this example, a 404 to any URL ending with <code class="docutils literal"><span class="pre">.php</span></code> or <code class="docutils literal"><span class="pre">.cgi</span></code> will <em>not</em> be
reported. Neither will any URL starting with <code class="docutils literal"><span class="pre">/phpmyadmin/</span></code>.</p>
<p>The following example shows how to exclude some conventional URLs that browsers and
crawlers often request:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="kn">import</span> <span class="nn">re</span>
<span class="n">IGNORABLE_404_URLS</span> <span class="o">=</span> <span class="p">(</span>
<span class="n">re</span><span class="o">.</span><span class="n">compile</span><span class="p">(</span><span class="s1">r'^/apple-touch-icon.*\.png$'</span><span class="p">),</span>
<span class="n">re</span><span class="o">.</span><span class="n">compile</span><span class="p">(</span><span class="s1">r'^/favicon\.ico$'</span><span class="p">),</span>
<span class="n">re</span><span class="o">.</span><span class="n">compile</span><span class="p">(</span><span class="s1">r'^/robots\.txt$'</span><span class="p">),</span>
<span class="p">)</span>
</pre></div>
</div>
<p>(Note that these are regular expressions, so we put a backslash in front of
periods to escape them.)</p>
<p>If you’d like to customize the behavior of
<a class="reference internal" href="../ref/middleware.html#django.middleware.common.BrokenLinkEmailsMiddleware" title="django.middleware.common.BrokenLinkEmailsMiddleware"><code class="xref py py-class docutils literal"><span class="pre">django.middleware.common.BrokenLinkEmailsMiddleware</span></code></a> further (for
example to ignore requests coming from web crawlers), you should subclass it
and override its methods.</p>

<p class="last">Filtering sensitive data is a hard problem, and it’s nearly impossible to
guarantee that sensitive won’t leak into an error report. Therefore, error

avoid transmitting error reports unencrypted over the Internet (such as
through email).</p>

<div class="section" id="s-filtering-sensitive-information">
<span id="filtering-sensitive-information"></span><h3>Filtering sensitive information<a class="headerlink" href="#filtering-sensitive-information" title="Permalink to this headline">¶</a></h3>
<p>Error reports are really helpful for debugging errors, so it is generally
useful to record as much relevant information about those errors as possible.
For example, by default Django records the <a class="reference external" href="https://en.wikipedia.org/wiki/Stack_trace">full traceback</a> for the
exception raised, each <a class="reference external" href="https://en.wikipedia.org/wiki/Stack_frame">traceback frame</a>’s local variables, and the
<a class="reference internal" href="../ref/request-response.html#django.http.HttpRequest" title="django.http.HttpRequest"><code class="xref py py-class docutils literal"><span class="pre">HttpRequest</span></code></a>’s <a class="reference internal" href="../ref/request-response.html#httprequest-attributes"><span class="std std-ref">attributes</span></a>.</p>
<p>However, sometimes certain types of information may be too sensitive and thus
may not be appropriate to be kept track of, for example a user’s password or
credit card number. So Django offers a set of function decorators to help you
control which information should be filtered out of error reports in a
production environment (that is, where <a class="reference internal" href="../ref/settings.html#std:setting-DEBUG"><code class="xref std std-setting docutils literal"><span class="pre">DEBUG</span></code></a> is set to <code class="docutils literal"><span class="pre">False</span></code>):

<dd><p>If a function (either a view or any regular callback) in your code uses

<p>To systematically hide all local variables of a function from error logs,
