Heroku is majorly to Deploy Ruby, Node.js, Clojure, and Java apps. But, you can also run any type of app (like Django). In this post I’ll explain how to deploy Django project on Heroku.

I assume that you already signed-up with Heroku and configured your SSH keys with Heroku servers. If you haven’t done it already, follow these instructions – http://devcenter.heroku.com/articles/quickstart

EDIT:
Sep 29th, 2011 – Heroku now officially supports Django – http://devcenter.heroku.com/articles/django
Sep 17th, 2011 – Added `gunicorn` to make the django project production ready.

OK, Let’s get started -

Create a folder for heroku app:
mkdir heroku-django
cd heroku-django

Create a virtualenv inside the heroku app folder and activate it:
virtualenv --no-site-packages .
source bin/activate

Install django and psycopg2 packages
bin/pip install django
env ARCHFLAGS="-arch i386 -arch x86_64" bin/pip install psycopg2
bin/pip install gunicorn


Save all the local site-packages to requirements.txt file
bin/pip freeze > requirements.txt


Create a new django project naming ‘django_project’
bin/django-admin.py startproject django_project


Edit django_project/settings.py file to Uncomment admin app of our django project:

vi django_project/settings.py

# After Uncommenting .admin and .admindocs app INSTALLED_APPS in settings.py looks like this:
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.staticfiles',
'django.contrib.admin',
'django.contrib.admindocs',
)


Create a Process file for heroku to run:
vi Procfile

Add these two lines:
web: bin/gunicorn_django --workers=4 --bind=0.0.0.0:$PORT django_project/settings.py
worker: bin/python django_project/manage.py celeryd -E -B --loglevel=INFO


Edit django_project/urls.py to add a controller for homepage and admin panel on django:

vi django_project/urls.py

Your urls.py file will have these lines after edit:

from django.conf.urls.defaults import patterns, include, url
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
    url(r'^$', 'views.home', name='home'),
    url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
    url(r'^admin/', include(admin.site.urls)),
)

Create a view for homepage:
vi django_project/views.py

Add these lines to views.py file, it just returns ‘Hello World!’ http response in plain text.

from django.http import HttpResponse

def home(request):
    return HttpResponse("Hello World!")

Add virtualenv folders to .gitignore list:
cat >.gitignore <<EOF
bin/
include/
lib/
EOF


Initialize a git repository and do initial commit:
git init
git add .
git commit -m "Initial Commit"

Create a heroku app with cedar stack, note that this command automatically sets the remote server as heroku with the url to new heroku app’s git repository:
heroku create --stack cedar

# just to verify the heroku remote
git remote show heroku

Your Heroku Folder will look like this (excluding virtualenv files):
.Python
.gitignore
Procfile
django_project/__init__.py
django_project/manage.py
django_project/settings.py
django_project/urls.py
django_project/views.py
readline-6.2.1-py2.6-macosx-10.6-universal.egg/readline.so
requirements.txt

Create (or Sync) database and tables:
heroku run bin/python django_project/manage.py syncdb --app vivid-water-6038

Now, Push the django files, Procfile and requirements.txt to Heroku (master branch):
git push heroku master

Here, replace vivid-water-6038 with your heroku app name.

Congratulations! you’ve just created your first django app on Heroku:
Access from http://your-app-name-here.herokuapp.com

My Heroku app:
http://vivid-water-6038.herokuapp.com

Have fun! :)

Thanks!

from Google IO 2011 Keynote - Image shows Android eating apple

Apple Keynote of iPad 2 Launch - Android Honeycomb 3.0 has only 100 apps

I like the fight between Apple and Google, which are great competitors in the mobile industry. Love the great innovations coming up from Google and the perfectionism from the Apple. :)

I went to Google IO 2011 Extended event at Google Bangalore office. It was a Live Streaming of the Google IO Keynote from San Francisco. Today (i.e., May 10th) from 9.00 PM to 10.30 PM. I had a nice free dinner at Google :D and played foosball for sometime before the event.

These are my quick notes of Google IO Keynote:

• Android Board (Anroid + Arduino)
• Music Beta App
• Android Accessories
• Android @ Home – operate the house appliances with an Anroid App
• Icecream Sandwich (Next Version of Android)
• Android 3.1 Honeycomb
• Project Tungsten – Speakers streaming from Music Beta (Inspired by Apple Air Play? :D)
• Touch the CD to play on Speakers using NFC Technology
• Movie Rental

All the Google IO participants at SF will be getting Samsung Galaxy Tab Limited Edition. Lucky them!

You can download my php-surblclient from here (or fork it!):
https://github.com/abhiomkar/php-surblclient

About SURBL
SURBLs are lists of web sites that have appeared in unsolicited messages. SURBL list can be used with programs that can check message body web sites against SURBLs, such as SpamAssassin 3 and others mentioned on the links page.

multi.surbl.org is a combined SURBL list where you can use this to find if this is Blacklisted under any of the surbl lists.

All of the SURBL data sources are combined into a single, bitmasked list: multi.surbl.org. Bitmasking means that there is only one entry per domain name or IP address, but that entry will resolve into an address (DNS A record) whose last octet indicates which lists it belongs to. The bit positions in that octet for the different lists are:
2 = comes from sc.surbl.org
4 = comes from ws.surbl.org
8 = comes from phishing data source (labelled as [ph] in multi)
16 = comes from ob.surbl.org
32 = comes from ab.surbl.org
64 = comes from jp data source (labelled as [jp] in multi)

If an entry belongs to just one list it will have an address where the last octet has that value, for example 127.0.0.8 means it comes from the phishing list and 127.0.0.2 means it’s in the data used in sc.surbl.org. An entry on multiple lists gets the sum of those list numbers as the last octet, so 127.0.0.6 means a record is on both ws.surbl.org and sc.surbl.org (comes from: 2 + 4 = 6). In this way, membership in multiple lists is encoded into a single response.

You need to download Pothana Font from here. And Extract to your Font folder of your home directory – ~/Library/Fonts. Make sure that you don’t have any other telugu fonts (Lohit or Pothana) installed at /Library/Fonts and ~/Library/Fonts, If present delete them.

or Enter these command in your Terminal App to install Pothana Font (Or do it manually as mentioned above) -
$ wget http://web.nickshanks.com/downloads/fonts/Pothana.ttf
$ mv Pothana.ttf ~/Library/Fonts


You need to restart the application (for example browser) to take effect.

To get eenadu font on Mac OS X -

$ wget http://dl.dropbox.com/u/1218282/eenadu.ttf
$ mv eenadu.ttf ~/Library/Fonts

Screenshot showing Pothana Font & Eenadu Font -

* I’m currently using Mac OS X Snow Leopard

Screenshot:

It shows ‘J’ here where it should be a smiley as shown in above screenshot.

Today evening I wrote a JavaScript code to replace this ‘J’ with the happy smiley from Yahoo Emoticons (My Favorite Smiley Theme). This script is available to everybody to use and very easy to install in your browser (~ Firefox 3.6 with Greasemonkey addon and ~ Google Chrome).

So, why it’s showing J instead of a smiley? Microsoft Outlook replaces :) with it’s J character of Wingdings font. It’s a proprietary font by Microsoft – as you expected Linux, Mac OS X and any other Operating System doesn’t have this font by default. If you don’t have this font, then you’ll see J.

If you are using Google Chrome, right click on the J letter and click on Inspect Element. This is how it looks in html code. As you can see this tag uses Wingdings font-family.

<span style="font-size:11.0pt;font-family:Wingdings;color:#1F497D">J</span>

J for Smile userscript that I wrote will replace this J with the corresponding Yahoo Emoticons.

Other Smileys
J for :) – Happy
K for :( – Sad
L for :| – Straight Face

How to Install?
Go to this link – http://userscripts.org/scripts/show/83513 and click on Install. Should work in Mozilla Firefox and Google Chrome.

Let me know your comments! :)

1. Type Coercion in Equal and not Equal ==, !== and ===, !===

2==2
//true

2=="2"
//true

2===2
//true

2==="2"
//false

It's been advised to use === and !== instead of == and !== for optimization and reliability. Hence, it avoids type coercion (typecasting).

2. bang bang (!!)

!!2
//true

!!0
//false

!!""
//false

**This is equal to Boolean() function

3. Unary Operator +

+"365"
//365

** Here '+' operator performs same thing as Number() function
4. Logical Operators - && and || are just like and & or operator in Python.

4 && 5 && 0 && 7
//0 - first faulty operand

0 || "" || 9 || 6
//9 - first truthy operand

will post the interesting things from the rest of his Videos. Ciao!
