On "magic", once again
So it seems Giles Bowkett is upset about use of the word “magic”. I’m happy to agree with the general consensus from various fora that the specific article he’s complaining about is, well, pretty much content-free. I could read that post over and over and still have no idea what actual things the author liked about Django or didn’t like about Rails. But I’ve pretty much learned to ignore content-free hype ...

Django Forms Quick Reference
Django's forms have fields like models, but you access them in a completely different way. I've found it hard to remember the correct way to access form field data properly, so this is a summary of the things I need to do with forms and how to do them. In particular these are useful in the form's __init__ method after calling super() to set up the form the way you want to. -

oEmbed y Django: incrusta contenidos de servicios web con django-oembed
oEmbed es un formato que permite usar una representación embebida de una URL en sitios web de terceros. La API de oEmbed permite a un sitio web incrustar contenido (como fotos o vídeos) de otros servicios web simplemente con un enlace al recurso que quiere se publicar. De esta forma se evita tener que utilizar una API distinta para incrustar contenidos de cada servicio web. Varios sitios como Flickr, Viddler, Qik, Hulu o Vimeo permiten acceder a sus contenidos mediante oEmbed. Además el sitio web oohEmbed sirve como wrapper para acceder a contenidos de otros sitios como YouTube, Wikipedia ó Wordpress.com entre otros ... -
Improved Django FormWizard
A few months back I had a project that I thought needed a wizard-style interface for one of its forms. For a while now Django has included the FormWizard class in django.contrib.formtools.wizard so I decided to use that. However, I immediately hit a couple of issues with it.FormWizard requires you to output the previous_fields context variable in each of the form's step templates. Django's -
ETag magic with Django
An ETag is a feature of HTTP that allows for a web server to know if content has changed since the last time the browser visited the page. The client sends the ETag from the cached page in a header. If the ETag in the header matches the current ETag then the server lets the browser know that the cached is up-to-date by sending back a 304 Not Modified response. -
ETag magic with Django
An ETag is a feature of HTTP that allows for a web server to know if content has changed since the last time the browser visited the page. The client sends the ETag from the cached page in a header. If the ETag in the header matches the current ETag then the server lets the browser know that the cached is up-to-date by sending back a 304 Not Modified response. The most natural way to build an ETag is to generate it from the HTML returned by the view, which I believe is how the default view caching works in Django. The downside of this is that the page is generated even if the client has a cached copy, and all that is saved is the cost of sending the page to the client. Bigger wins can be had by using Django's conditional view processing to calculate an ETag outside of the view. I haven't seen the requirements documented, but as far as I can tell there is only a single property needed in an ETag: The ETag should vary with the page, i.e. when the page content changes, the ETag chages. A simple alternative to generating an ETag from … -

Django Training
I’m pleased to announce that I’ll be teaching a week-long introductory Django course in Kansas City, September 21st - 25th. Teaching’s folks how to use Django is one of my favorite things to do – in fact, I’m in San Jose right now gearing up for a tutorial at OSCON tomorrow – so it seemed a natural thing to make it an aspect of my business. So, if you need to learn Django, why not come spend a week in Kansas City with me? -
Efficiently Test Emails in Django
Testing emails can be an inefficient process. The email needs to leave your machine, arrive at the SMTP server, get forwarded to your test mail server and then downloaded by your email client. Do you want those 30 seconds of your life back? Using an SMTP sink, you can receive the email to your screen instantly. Setup is easy. ♦ Download smtp_sink.py ♦ Put it in whatever your project directory is. You will want to create a "inbox" directory. Besides outputting to the screen, this will automatically copy the email to the inbox directory in case you need to reference it later ♦ Change your settings.py to have: EMAIL_HOST = '127.0.0.1', EMAIL_HOST_USER = '', EMAIL_PORT = 25 If you have a script that loads your sandbox environment automatically, you will want to load smtp_sink.py automatically. It will send a test signal to see if it's already running and not start twice. If you run automated test scripts, the output of the "inbox" can be tested. -

Django, Push Notifications, and Prowl
One issue that I have had with this blog for a while has been the lack of notifications when a new, legitimate comment is posted under one of my articles. I don’t get many comments, but when I do, I would like to be able to respond right away. I don’t like email notifications, so when Prowl was announced this week, I was excited about the possibility of sending push notifications to my iPhone whenever a new comment was posted. It turned out to be much easier than I anticipated, thanks to Jacob Burch’s Prowlpy module and Django’s signals framework. To setup push notifications for anything, you need to get these done first: Register for an account at the Prowl site, then go to iTunes Store and buy Prowl for your iPhone/iPod Touch After setting up your device, login to your account at the Prowl web site, click on Settings, and generate an API key Download and install Prowlpy and httplib2. I opted for simply putting Prowlpy somewhere on my PYTHONPATH, and installing httplib2 through aptitude: sudo apt-get install python-httplib2 Now that you are ready, simply create a signals.py file under whichever Django application you would like to use to … -
Django Training
I'm pleased to announce that this September, Revolution Systems will be offering a four-day Django training course here in Kansas City, taught by Jacob Kaplan-Moss. Jacob has taught a number of similar courses privately in the past, but this is the first time we're opening this up to the public. If you've been wanting to really learn Django, this is a great chance. The class is intended for relative beginners to Django, but by the time you leave you'll know enough to create some pretty awesome websites. The class will be Monday, September 21 - Friday, September 25, 2009 in Kansas City, MO. For more, or to sign up, check out the full details. -
Pyrohose Logo Design
I spent last weekend finishing up a logo for a super secret project I can't go into yet at the client's request. I can share the logo in the meantime. When the client gives me the green-light I'll come back and update the post with a link to the project. -
Python Job Alert
My employer is looking for a new Python developer to work here in Oxford, UK. The company I work for runs 2degreesnetwork.com, which is collaboration service for sustainable business. Basically, it's a social networking type of site for businesses to collaborate on climate change and related issues. I'm not officially allowed to say this, but the closest analogy is ‘Facebook for Businesses’. This is the office. Ignore the man in the far corner, he is just a hobo that wandered in. The site is built with Django, so obviously Django experience would be a bonus, but experience with any MVC framework would be valuable. We're looking for someone who isn't necessarily a specialist and who doesn't mind getting to grips with new technology and dabbling in the front-end from time to time. You will be working in a very relaxed working environment with a diverse bunch of characters. The full job description is below, but all you really need to know is that you will be working with yours truly! If you are interested, Email your CV to james DOT tarin AT 2degreesnetwork DOT com. Would you like to do something genuinely useful with your Software Development skills (Python/Django)? 2degrees … -

Twenty questions about the GPL
foo.py is a Python library released under the GPLv3. bar.py is a library distributed commercially. If bar contains import foo, must bar.py be released under the GPL? Does the answer change if foo.py does not ship with bar.py, but nonetheless requires foo.py to function? Does the answer change if foo.py does not ship with bar.py and does not require its presence to function? libfoo.so is a C shared library released under the GPLv3. -

Django internals: authentication
Django’s session and authentication frameworks are designed to Just Work™, and can seem pretty magical. Like the rest of Django, though, these parts aren’t magic — just Python. So let’s take a look at the internals of sessions and authentication and see how the whole thing works. Our journey begins with the session middleware. You’ll see that the process_request method is pretty simple: it looks up the session engine setting, looks for a session key in the request’s cookies, and then sets request. -
Django powered AJAX Chat – Part 2
I’m sorry I left my last Django powered AJAX Chat – Part 1 post so abandoned, we have been dealing with an ever increasing amount of study stuff at the uni and I didn’t have much time to keep on writing about our chat application. I have been working hard to improve some of the functionality of the application, both on the Django side and the jQuery side. There are still many rough edges, but this time I’ve got some more along the lines of plug&play. So, just for those impatient ones who like to see to believe, this is a screenshot of it in action: Screenshot of the Django chat application using the jQuery Javascript library, you can appreciate the use of special formatting for users who are joining the room, normal formatting for user messages and... yes... smileys! Pretty neat, huh? There is a lot of ground to cover with this one, so maybe I’ll split this post in two… we will see. The Idea Have a pure Django + jQuery chat application working on our site. The users will be presented with a GUI like the one above, listing the messages in the chat room, and will …
