as a chrome plugin

This image shows how the chrome plugin would display profiled data, once it is configured & installed

on command line

See this file in the PR to see how to use the context manager, and how easy it is to find performance issues :-)

The output of Django query profiler is same for the command line or the chrome plugin. In fact, chrome plugin displays the output set by the middleware - which is just a plain wrapper around context manager.

installation

The simplest way to getting started is to install the django query profiler from pip, and get the chrome plugin from chrome web store.

Python package:

pip install django-query-profiler

Chrome Plugin:

Download from chrome webstore

This is covered in detail in the installation section in the docs

configuration:

This configuration is when we want to use the profiler along with the chrome plugin. If we want to just use it on the command line, the configuration is much more simpler (two lines of change to settings.py file) - that is covered in the docs

settings.py:

from django_query_profiler.settings import *

INSTALLED_APPS = (
    ...
    'django_query_profiler',
    ...
)

MIDDLEWARE = (
    ...
     # Request and all middleware that come after our middleware, would be profiled
    'django_query_profiler.client.middleware.QueryProfilerMiddleware',
    ...
)

DATABASES = (
    ...
    # Adding django_query_profiler as a prefix to your ENGINE setting
    # Assuming old ENGINE was "django.db.backends.sqlite3", this would be the new one
    "ENGINE": "django_query_profiler.django.db.backends.sqlite3",
)

urls.py:

# Add this line to existing urls.py
path('django_query_profiler/', include('django_query_profiler.client.urls'))

See this PR on how to configure this in your application, and how the plugin is going to look like after your configuration

This is covered in detail in the configuration instructions section in the docs
