Commands
========
+
+The Debug Toolbar currently provides one Django management command.
+
+``debugsqlshell``
+-----------------
+
+This command starts an interactive Python shell, like Django's built-in
+``shell`` management command. In addition, each ORM call that results in a
+database query will be beautifully output in the shell.
+
+Here's an example::
+
+ >>> from page.models import Page
+ >>> ### Lookup and use resulting in an extra query...
+ >>> p = Page.objects.get(pk=1)
+ SELECT "page_page"."id",
+ "page_page"."number",
+ "page_page"."template_id",
+ "page_page"."description"
+ FROM "page_page"
+ WHERE "page_page"."id" = 1
+
+ >>> print p.template.name
+ SELECT "page_template"."id",
+ "page_template"."name",
+ "page_template"."description"
+ FROM "page_template"
+ WHERE "page_template"."id" = 1
+
+ Home
+ >>> ### Using select_related to avoid 2nd database call...
+ >>> p = Page.objects.select_related('template').get(pk=1)
+ SELECT "page_page"."id",
+ "page_page"."number",
+ "page_page"."template_id",
+ "page_page"."description",
+ "page_template"."id",
+ "page_template"."name",
+ "page_template"."description"
+ FROM "page_page"
+ INNER JOIN "page_template" ON ("page_page"."template_id" = "page_template"."id")
+ WHERE "page_page"."id" = 1
+
+ >>> print p.template.name
+ Home

Configuration
=============
+
+The debug toolbar has two settings that can be set in ``settings.py``.
+
+#. Optional: Add a tuple called ``DEBUG_TOOLBAR_PANELS`` to your ``settings.py``
+ file that specifies the full Python path to the panel that you want included
+ in the Toolbar. This setting looks very much like the ``MIDDLEWARE_CLASSES``
+ setting. For example::
+
+ DEBUG_TOOLBAR_PANELS = (
+ 'debug_toolbar.panels.version.VersionDebugPanel',
+ 'debug_toolbar.panels.timer.TimerDebugPanel',
+ 'debug_toolbar.panels.settings_vars.SettingsVarsDebugPanel',
+ 'debug_toolbar.panels.headers.HeaderDebugPanel',
+ 'debug_toolbar.panels.request_vars.RequestVarsDebugPanel',
+ 'debug_toolbar.panels.template.TemplateDebugPanel',
+ 'debug_toolbar.panels.sql.SQLDebugPanel',
+ 'debug_toolbar.panels.signals.SignalDebugPanel',
+ 'debug_toolbar.panels.logger.LoggingPanel',
+ )
+
+ You can change the ordering of this tuple to customize the order of the
+ panels you want to display, or add/remove panels. If you have custom panels
+ you can include them in this way -- just provide the full Python path to
+ your panel.
+
+#. Optional: There are a few configuration options to the debug toolbar that
+ can be placed in a dictionary called ``DEBUG_TOOLBAR_CONFIG``:
+
+ * ``INTERCEPT_REDIRECTS``
+
+ If set to True, the debug toolbar will show an intermediate page upon
+ redirect so you can view any debug information prior to redirecting. This
+ page will provide a link to the redirect destination you can follow when
+ ready. If set to False (default), redirects will proceed as normal.
+
+ * ``SHOW_TOOLBAR_CALLBACK``
+
+ If not set or set to None, the debug_toolbar
+ middleware will use its built-in show_toolbar method for determining whether
+ the toolbar should show or not. The default checks are that DEBUG must be
+ set to True and the IP of the request must be in INTERNAL_IPS. You can
+ provide your own method for displaying the toolbar which contains your
+ custom logic. This method should return True or False.
+
+ * ``EXTRA_SIGNALS``
+
+ An array of custom signals that might be in your project,
+ defined as the python path to the signal.
+
+ * ``HIDE_DJANGO_SQL``
+
+ If set to True (the default) then code in Django itself
+ won't be shown in SQL stacktraces.
+
+ * ``SHOW_TEMPLATE_CONTEXT``
+
+ If set to True (the default) then a template's
+ context will be included with it in the Template debug panel. Turning this
+ off is useful when you have large template contexts, or you have template
+ contexts with lazy datastructures that you don't want to be evaluated.
+
+ * ``TAG``
+
+ If set, this will be the tag to which debug_toolbar will attach the
+ debug toolbar. Defaults to 'body'.
+
+ * ``ENABLE_STACKTRACES``
+
+ If set, this will show stacktraces for SQL queries
+ and cache calls. Enabling stacktraces can increase the CPU time used when
+ executing queries. Defaults to True.
+
+ * ``HIDDEN_STACKTRACE_MODULES``
+
+ Useful for eliminating server-related entries which can result
+ in enormous DOM structures and toolbar rendering delays.
+ Default: ``('socketserver', 'threading', 'wsgiref', 'debug_toolbar')``.
+
+ (The first value is ``socketserver`` on Python 3 and ``SocketServer`` on
+ Python 2.)
+
+ * ``ROOT_TAG_ATTRS``
+
+ This setting is injected in the root template div in order to avoid conflicts
+ with client-side frameworks. For example, when using with Angular.js, set
+ this to 'ng-non-bindable' or 'class="ng-non-bindable"'. Defaults to ''.
+
+ * ``SQL_WARNING_THRESHOLD``
+
+ The SQL panel highlights queries that took more that this amount of time,
+ in milliseconds, to execute. The default is 500.
+
+ Example configuration::
+
+ def custom_show_toolbar(request):
+ return True # Always show toolbar, for example purposes only.
+
+ DEBUG_TOOLBAR_CONFIG = {
+ 'INTERCEPT_REDIRECTS': True,
+ 'SHOW_TOOLBAR_CALLBACK': custom_show_toolbar,
+ 'EXTRA_SIGNALS': ['myproject.signals.MySignal'],
+ 'HIDE_DJANGO_SQL': False,
+ 'TAG': 'div',
+ 'ENABLE_STACKTRACES' : True,
+ 'HIDDEN_STACKTRACE_MODULES': ('gunicorn', 'newrelic'),
+ }

Installation
============
+
+#. The recommended way to install the Debug Toolbar is via pip_::
+
+ $ pip install django-debug-toolbar
+
+ If you aren't familiar with pip, you may also obtain a copy of the
+ ``debug_toolbar`` directory and add it to your Python path.
+
+ .. _pip: http://www.pip-installer.org/
+
+
+ To test an upcoming release, you can install the `in-development version
+ <http://github.com/django-debug-toolbar/django-debug-toolbar/tarball/master#egg=django-debug-toolbar-dev>`_
+ instead with the following command::
+
+ $ pip install django-debug-toolbar==dev
+
+#. Add the following middleware to your project's ``settings.py`` file::
+
+ MIDDLEWARE_CLASSES = (
+ # ...
+ 'debug_toolbar.middleware.DebugToolbarMiddleware',
+ # ...
+ )
+
+ Tying into middleware allows each panel to be instantiated on request and
+ rendering to happen on response.
+
+ The order of ``MIDDLEWARE_CLASSES`` is important: the Debug Toolbar
+ middleware must come after any other middleware that encodes the
+ response's content (such as GZipMiddleware).
+
+ .. note::
+
+ The debug toolbar will only display itself if the mimetype of the
+ response is either ``text/html`` or ``application/xhtml+xml`` and
+ contains a closing ``</body>`` tag.
+
+ .. note ::
+
+ Be aware of middleware ordering and other middleware that may intercept
+ requests and return responses. Putting the debug toolbar middleware
+ *after* the Flatpage middleware, for example, means the toolbar will not
+ show up on flatpages.
+
+#. Make sure your IP is listed in the ``INTERNAL_IPS`` setting. If you are
+ working locally this will be::
+
+ INTERNAL_IPS = ('127.0.0.1',)
+
+ .. note::
+
+ This is required because of the built-in requirements of the
+ ``show_toolbar`` method. See below for how to define a method to
+ determine your own logic for displaying the toolbar.
+
+#. Add ``debug_toolbar`` to your ``INSTALLED_APPS`` setting so Django can
+ find the template files associated with the Debug Toolbar::
+
+ INSTALLED_APPS = (
+ # ...
+ 'debug_toolbar',
+ )
