This document summarizes a talk about making Django and NoSQL databases like MongoDB play nicely together. Currently, Django's ORM is optimized for SQL databases and makes assumptions that don't always apply to NoSQL databases. The talk proposes some changes to address this, including having the Query object do less database-specific work and pushing more of that down to the individual database compilers. This would make the Query more agnostic and allow the compilers to generate queries optimized for their specific databases. An example backend for MongoDB would be built to demonstrate this approach.
This is the slides I used when I shared my humble insight on Django to the students in University of Taipei in 2016. Please feel free to correct me if there is anything wrong.
Django is a Python web framework named after jazz musician Django Reinhardt. It features an object-relational mapper, reusable apps, a template language, admin interface, and testing framework. Many large sites use Django including NASA, PBS, and news organizations. It has a vibrant community and over 650 pages of documentation.
Django is a high-level Python web framework that encourages rapid development and clean design. It includes features like an object-relational mapper, automatic admin interface, URL dispatcher, template system, cache system, internationalization support, form handling, and more. Django reads metadata from models to generate a production-ready admin interface for adding and updating content. Views interact with models to generate querysets for templates to display as responses. The framework handles common tasks to allow developers to focus on project-specific code.
The document discusses the Django admin interface and alternatives. It describes when to use the Django admin, such as for initial data entry but not public end users. It also discusses customizing the admin display and functions. Finally, it reviews some alternative admin apps for Django like django-xadmin and django-grappelli as well as admin plugins for other frameworks like Flask.

This document discusses options for using Django with MongoDB, including object-document mappers like MongoEngine and Mongokit. It notes that some Django contrib apps may be broken, but the admin will work. Key advantages of using Django and MongoDB together include reduced impedance mismatch, support for new fields like aggregations and GridFS, and ability to continue using Django without changes. It provides suggestions like embedding documents where possible, using raw queries, considering models, and contributing to open source projects.
Mongoengine is a popular Python ORM for MongoDB that provides a Django-like interface for defining document schemas and interacting with MongoDB collections. It allows defining document fields and embedding documents, and can be used with or without Django. When used with Django, it provides integration with Django features like authentication, sessions, and storage, but some aspects like caching, testing, and generic views require additional configuration to work as expected with MongoDB.
Django is a high-level Python web framework that allows for fast development, automates repetitive tasks, and follows best practices. It provides features like an admin interface, elegant URL design, templates, and is powerful yet easy to use for web development.

Javascript and first-class citizenry: require.js & node.js
Javascript on web pages is ubiquitous and its problems are legendary. Javascript, seen as a second-class code citizen, is usually hacked together even by seasoned developers. New libraries (jQuery, prototype, backbone, knockout, underscore) and runtime tools (firebug, jasmine) look like they solve many problems - and they do. But they still leave poorly written code as just that. One key problem is that all javascript code lives globally and this results in poorly managed, tested and delivered code.
In this session, I will illustrate that we can treat javascript as a first-class citizen using with require.js and node.js: it can be modular, encapsulated and easily unit tested and added to continuous integration cycle. The dependencies between javascript modules can also be managed and packaged just like in C# and Java. In the end, we can resolve many javascript difficulties at compile time rather than waiting until runtime.
This document contains Simon Willison's heresies about Django. Some of the heresies discussed include that the {% if %} tags in Django templates suck, that silencing template errors is a bad idea, and that settings.py causes problems. Alternatives proposed include using a smarter {% if %} tag snippet, not silencing errors, and allowing per-application settings instead of one global settings file. The document also advocates for improving testing and documentation in the Django community.
Create responsive websites with Django, REST and AngularJSHannes Hapke
The document discusses 10 steps to make a Django site more responsive by adding a REST API and using AngularJS for the front-end: 1) Create an API endpoint for the Django models, 2) Set up the JavaScript environment and install AngularJS, 3) Create a static AngularJS site, 4) Use verbatim tags to avoid conflicts between Django and AngularJS variables, 5) Connect AngularJS to the API, 6) Take advantage of the Django REST Framework features, 7) Handle asynchronous data loading, 8) Add forms and POST requests, 9) Clean up settings.py, and 10) Document the API. The goal is to keep the back-end lightweight Django while building a more responsive and
This document provides an overview of using the Backbone.js framework for client-side MVC applications. It discusses why Backbone is useful for structuring JavaScript applications, its core architecture including models, collections, views and routers. It also provides examples of how to convert jQuery code to use a Backbone-based approach and lists some real-world applications that use Backbone.
Drupal 8 introduces a lot of changes for javascript: how to add a JS file to a page, how Drupal process the aggregation of JS files, what are the new javascript APIs. We'll be looking into the reasons for those changes.
After a quick recap of the changes you need to make to port your JS to Drupal 8, we'll dig into the changes you should embrace as a module maintainer or site developer to make your life, and the web, better.
But it's not all pretty, when you want to use some more advanced D8 features with your JS, you have to use messy workarounds. We'll look at a few examples of what happens when Backbone, Drupal and fancy functionalities meet in core and what it'd take to fix the mess.
Django is very stable web-framework that has been actively developed over past ten years. There might be many tutorials and talks out there about Django but there is hardly one that is more catered to mobile developers. After all, mobile developers have to carefully choose a backend for their app because it’s the building block of a good project.This talk is not only for mobile app developers but also for beginners in both Python and Django. This talk will suggest libraries and show how they can help you implement a wonderful and flexible project. Video : https://www.youtube.com/watch?v=-RpxpKuyCBE&t=1s

Writing clean code using test-driven development (TDD) involves:
1. Writing small, focused unit tests before writing the code to make them pass;
2. Iteratively writing just enough code to pass each test, then refactoring the code;
3. Following principles of clean code like using meaningful names, short functions that do one thing well, and formatting for readability.
The presentation demonstrated converting Roman numerals to Arabic using TDD, highlighting benefits like producing readable, maintainable code with test coverage and living documentation.

- The worldwide movement toward economic, financial, trade, and communications integration.
Globalization implies the opening of local and nationalistic perspectives to a broader outlook of an interconnected and interdependent world with free transfer of capital, goods, and services across national frontiers. However, it does not include unhindered movement of labor and, as suggested by some economists, may hurt smaller or fragile economies if applied indiscriminately
E-commerce in India is growing the fastest globally and is projected to continue rapid expansion. Retail e-commerce in particular has grown over 40% annually, reaching 60% of online users, though it remains below global averages. Key players like Flipkart, Snapdeal and Amazon have millions of unique visitors monthly and over 100% growth year-over-year. However, e-commerce companies face challenges like high inventory costs, need for localized payment and fulfillment options, and meeting consumers' expectations for deals and low-cost or free shipping. How companies address these issues will determine which ones succeed in India's competitive e-commerce market.

Their approach not only maintains the confidentiality of the original data but also enhances the utility and scalability of LLMs under privacy constraints. Attendees, including machine learning engineers, data scientists, and data managers, will witness first-hand how Secludy's integration with Milvus empowers organizations to harness the power of LLMs securely and efficiently.
Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

• Without Alternatives, how difficult it was to estimate ?
• Ideas -> Conceptualization -> Enterprise Ready was full of Effort, Pain,
Time waste, Complexity & Change !!!
• Was my system adaptive to the change that business demand? … God
it was really nightmare to maintain the code ….
• What is the time it took to get the customer from a frustrated to a happy
customer ? also the time it took to develop version 2, with different
requirements & scale:

4. Time is an essence
Python : Django A complete framework
A Web Framework that shortens the Time it takes to develop
software in at least an Order of Magnitude. while also
tremendously minimizing Effort Pain, Time waste, Complexity,
Cost of change & more

5. Python: Language of Best
• By The organizations attracting the best Programmers
in the world
Google, NASA, MIT
5
6. • “The framework for perfectionists
with deadlines”
• Model-Template-View ( MTV ) not as
complex as MVC
• Flexible template language that can
be used to generate HTML, CSV,
Email or any other format
• Includes ORM that supports many
databases – Postgresql, MySQL,
Oracle, SQLite
• Lots of extras included –
middleware, csrf protections,
sessions, caching, authentication
• Written in C – high
performance, ability to link to
C libraries for extensions
• Interpreted script language
compiled on the fly into byte
code
• Easier to read coding
standards – whitespace
sensitive
• Object Oriented
WHY
6
7. Scalability
• Django runs on regular web servers, such as
Apache, Lighty or Nginx, using a built-in Python
or WSGI adapter
• This makes it very lightweight & scalable, as any
LAMP deployment
o There are examples of sites that handle MM reqs/hour, using less
than 10 servers
7
8. IT Acceptance
• IT environments today are mostly familiar with
Java
• Solution: use Jython that compiles Python to
bytecode
o Package a Django project as .war
o Sun constantly improves Jython & maintains compatibility /w
Django
8
11. settings.py
• Defines settings used by a Django application
• Referenced by wsgi.py to bootstrap the project
loading
• Techniques for managing dev vs prod settings:
o Create settings-dev.py and settings-prod.py and use symlink to link
settings.py to the correct settings
o Factor out common settings into base-settings.py and import. Use
conditionals to load correct settings based on DEBUG or other setting
11
14. Django Models
• Defined in models.py
• Typically inherit from django.db.models.Model
Example Model:
from django.db import models
class TestModel(models.Model):
name = models.CharField(max_length = 20)
age = models.IntegerField()
14
15. Models (cont’d)
• Default is to set NOT NULL on all fields. Override by
adding null = True to field definition:
name = models.CharField(max_length=20, null =
True)
• Relationships defined through special field types:
models.OneToOneField(model)
models.ForeignKey(model)
models.ManyToManyField(model)
15
16. Models (cont’)
• Need Nulls in a Boolean Field? Use
models.NullBooleanField()
• Set Default value with “default”:
count = models.IntegerField(default = 0)
• Use a inner Meta class to define additional options,
especially useful for abstract classes:
class TestModel(models.Model):
class Meta:
abstract = True
16
18. Activating a Model
• Add the app to INSTALLED_APPS in settings.py
• Run manage.py validate
• Run manage.py syncdb
• Migrations
o Write custom script or manually handle migrations
o Use South
18
19. Selecting Objects
• Models include a default manager called objects
• Manager methods allow selecting all or some
instances
Question.objects.all()
Question.objects.get(pk = 1)
Use try block, throws DoesNotExist
exception if no match
Question.objects.filter(created_date__lt = ‘2014-
01-01’)
• Returns QuerySet
19
21. Full Sample
from django.db import models
from datetime import datetime
class TimestampedModel(models.Model):
created_datetime = models.DateTimeField()
updated_datetime = models.DateTimeField()
def save(self, *args, **kwargs):
if self.id is None:
self.created_datetime = datetime.now()
updated_datetime = datetime.now()
super(TimestampedModel,self).save(*args, **kwargs)
class Meta:
abstract = True
21
22. Full Sample (cont’d)
class Question(TimestampedModel):
question_text = models.CharField(max_length = 200)
def __str__(self):
return self.question_text
22
23. Function vs. Class Views
• Django allows two styles of views – functions or class
based views
• Functions – take a request object as the first
parameter and must return a response object
• Class based views – allow CRUD operations with
minimal code. Can inherit from multiple generic
view classes (i.e. Mixins)
23
24. Sample – Viewing a List
of Questions
• Function based:
from .models import Question
from django.shortcuts import render_to_response
def question_list(request):
questions = Question.objects.all()
return render_to_response(‘question_list.html’, {
‘questions’:questions})
24
25. Quick CRUD Operations
with Generic Views
• ListView
• UpdateView
• CreateView
• If Model is specified, automagically creates a
matching ModelForm
• Form will save the Model if data passes validation
• Override form_valid() method to provide custom
logic (i.e sending email or setting additional fields)
25
26. Sample – As Class Based
View
from .models import Question
from django.views.generic import ListView
class QuestionList(ListView):
model = Question
context_object_name = ‘questions’
26
27. Django Templates
• Very simple syntax:
variables = {{variable_name}}
template tags = {%tag%}
• Flexible – can be used to render html, text, csv,
email, you name it!
• Dot notation – template engine attempts to resolve
by looking for matching attributes, hashes and
methods
27
28. Question List Template
<!doctype html>
<html lang=en>
<head>
<meta charset=utf-8>
<title>List of Questions</title>
</head>
<body>
{%if questions%}
<ul>
{%for q in questions%}
<li>{{q.question_text}}</li>
{%endfor%}
</ul>
{%else%}
<p>No questions have been defined</p>
{%endif%}
</body>
</html>
28
29. urls.py
• Defines routes to send urls to various views
• Can use regular expressions
• Extract parameters from a url and pass to the view
as a named parameter:
r(‘^question/(?P<question_id>d+)/$’,’views.question_
detail’)
• Extensible – urls.py can include additional url files
from apps:
r(‘^question/’,include(question.urls))
29
30. Forms in Django
• django.forms provides a class to build HTML forms
and validation. Example:
from django import forms
class EditQuestionForm(forms.Form):
question_text = forms.CharField(max_length = 200)
• Often redundant when creating forms that work on
a single model
30
31. ModelForms
• Automatically generate a form from a model.
• Handles saving a bound model
• Can specify fields to be included or excluded in the
form
• Sample:
from django.forms import ModelForm
from .models import Question
class QuestionForm(ModelForm):
class Meta:
model = Question
fields = [‘question_text’]
31
32. Using a ModelForm
• Create an instance of an empty form:
form = QuestionForm()
• Create a form to update an existing instance of a
model:
question = Question.objects.get(pk = 1)
form = QuestionForm(instance = question)
• Pass the form into the template and use the form
methods to render the form:
form.as_p
form.as_ul
form.<field_name>
form.<field_name>.errors
32
33. Request & Response
• Request object encapsulate the request and provide
access to a number of attributes and methods for
accessing cookies, sessions, the logged in user object,
meta data (i.e environment variables),
• Response objects are returned to the browser. Can set
content type, content length, response does not have
to return HTML or a rendered template
• Special response types allow for common functionality:
HttpResponeRedirect
Http404
HttpStreamingResponse
33
34. Django Extras
• CRSF Middleware – enabled by default. Include
template tag in all forms:
{%csrf_token%}
• Authentication
• Caching
• Sessions
• Messages
• Email
• Logging
34
35. Auth Decorators
• Live in django.contrib.auth.decorators
• login_required
@login_required
def function_view(request):
….
• user_passes_test (can be used with lambda
functions for real power) –
@user_passes_test(lambda u: u.is_staff)
def function_view(request):
…
• has_perms – test for user permissions
35
36. Demo: 30 mins
Let’s develop an Release Tracking system
o Create Business Data Model
o Database CRUD Operations to manage/add/edit/delete Releases
o Rich Web UI (search, filters, last actions)
o Users management (permissions, groups), User logging, Access level
control
o Scalable deployment (any # of users)
36
37. Step1: Settings: Connect to
Database
• DATABASES = {
• 'default': {
• 'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
• 'NAME': ‘release', # Or path to database file if using sqlite3.
• # The following settings are not used with sqlite3:
• 'USER': 'root',
• 'PASSWORD': ‘',
• 'HOST': 'localhost', # Empty for localhost through domain sockets or '127.0.0.1' for localhost through TCP.
• 'PORT': '', # Set to empty string for default.
• }
• }
37
38. Step2: Data Model
from django.db import models
class Environment(models.Model):
environment = models.CharField(null=False, max_length=200)
# Create your models here.
class Release(models.Model):
dateCreated = models.DateField(null=False, auto_now_add=True)
releaseDate = models.DateField(null=False)
releaseTitle = models.CharField(null=False, max_length=200)
releaseEnv = models.ForeignKey(Environment)
38
39. Step3: Sync DB
django_manage.py syncdb
Whoooo ---- Your DB tables are created
What Next Lets create some Interfaces
39
40. Register Admin
from django.db import models
from django.contrib import admin
class Environment(models.Model):
environment = models.CharField(null=False, max_length=200)
# Create your models here.
class Release(models.Model):
dateCreated = models.DateField(null=False, auto_now_add=True)
releaseDate = models.DateField(null=False)
releaseTitle = models.CharField(null=False, max_length=200)
releaseEnv = models.ForeignKey(Environment)
admin.site.register(Release)
admin.site.register(Environment)
40
41. Admin Interface Ready
• Run manage.py runserver 8000
http://127.0.0.1:8000/admin/
- Entire CRUD Operation for
Models
- User Authentication, Groups,
Access Level & control
- User Log
- Multisite & Multi Application
41
42. Views: Front End
• Setup a URL pattern : Edit url.py
url(r'^$', 'ReleaseTracker.views.home', name='home'),
. Create view as home
# Create your views here.
from django.http import HttpResponse
from rtracker.models import Environment
from rtracker.models import Release
from django.shortcuts import get_object_or_404, render_to_response
from django.template import RequestContext
def home(request):
releaseitems = Release.objects.all()
return render_to_response('home.html', {'releaseitems': releaseitems},
context_instance=RequestContext(request))
42
43. Create Template
Create home.html in templates
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
{# you can include templates #}
{% include "nav.html" %}
{% for release in releaseitems %}
{{release.releaseTitle}}
{% endfor %}
</body>
</html>
43
44. FRONT END
• Open http://127.0.0.1:8000/
You will be able to see the model data
44
