django-debug-toolbar-line-profiler 0.6.1

Installation

To install the line_profiler panel, first install this package with pip install django-debug-toolbar-line-profiler, then add debug_toolbar_line_profiler to the INSTALLED_APPS:

INSTALLED_APPS = (
    ...
    'debug_toolbar_line_profiler',
)

and add the panel to DEBUG_TOOLBAR_PANELS:

DEBUG_TOOLBAR_PANELS = (
    ...
    'debug_toolbar_line_profiler.panel.ProfilingPanel',
)

Configuration

By default, the panel will profile your view function. If you use class based views the panel will profile all functions on the class that don’t start with _. If you want additional code to be profiled, add the @profile_additional decorator like so:

from debug_toolbar_line_profiler import profile_additional
from boto.s3.connection import S3Connection

...

@profile_additional(S3Connection.make_request)
def your_view_code(*args, **kwargs):
    ...

Signals

There is also a signal (debug_toolbar_line_profiler.signals.profiler_setup) that you can attach to for integrating class based views like django rest framework.

Here is an example:

from rest_framework.viewsets import ViewSet
from rest_framework.response import Response
from debug_toolbar_line_profiler import signals


class AViewSet(ViewSet):
    def list(self, request):
        return Response([])

    def retrieve(self, request, pk=None):
        return Response({})


def register_profile_views(sender, profiler, **kwargs):
    profiler.add_function(AViewSet.list)
    profiler.add_function(AViewSet.retrieve)


signals.profiler_setup.connect(register_profile_views,
                               dispatch_uid='register_profile_views')
