Pensar en el manteniment compensa
Avui, fa poques hores hem posat en producció una nova web per Fiesta Hotel Group anomenada Palladium Weddings és una web pensada per pantalles grans, on s'intenta mostrar el que és el producte de noces que té el client. Si us pensau casar aviat o renovar vots, no deixeu de fer-li una ullada, els escenaris i ambients són una autèntica meravella. Com és habitual la web està desenvolupada amb Django i pensada per a suportar una càrrega important de visites, i a la vegada fer que el manteniment dels continguts sia el més ràpid possible. Pensau que muntar un paquet de noces, amb tot els extres, fotografies, escenaris, ... no és una tasca trivial. Ens hem de posar amb la pell no tan sols del client potencial que visita la web, sinó de la gent que l'ha de mantenir, i per tant l'aplicació s'ha de cuidar tant en l'aspecte visible com en el que es veu menys, però que també té una part fonamental en l'èxit de la web. Si aconseguim fer una web fàcil de mantenir és més senzill que els continguts es mantenguin actualitzats i que la web estigui més viva. Però a part d'aquestes consideracions, per mi … -
Django scaffolding
We all love Django — a simple but powerful framework. However, Ruby on Rails has at least one (and few others I’m sure!) advantage: scaffolding. It allows developers to create the models, views, and templates in a single operation. It’s an interesting solution — you don’t have to manually create all the things that usually take a lot of time. So why don’t we have this feature in Django? Well… now we do! Our latest django-common 0.3 comes with a scaffolding feature! Overview Here is what django-common scaffold can do: - create app, - create models, - create views, - create templates, - create forms, - create urls, - create tests. Scaffold creates the app (similar to startapp that ships with Django), models with fields, CRUD views with ajax forms, prepares templates, fills urls, and creates CRUD tests with only one command! Installing Use pip installer: pip install django-common-helpers Or just download/clone directly from github: https://github.com/Tivix/django-common Then add it (django_common) to INSTALLED_APPS and set up SCAFFOLD_APPS_DIR in settings. Default is set to main app directory. However if you use django_base_project you must set up this to SCAFFOLD_APPS_DIR = ‘apps/’. Run scaffold, run! To run scaffold type:python manage.py scaffold APPNAME --model … -
Moving Sentry from Heroku to Hardware
Update: Don't decide against Heroku just because you've read my blog. It makes some things (especially prototyping) very easy, and with certain kinds of applications it can work very well. I've talked a lot about how I run getsentry.com, mostly with my experiences on Heroku and how I switched ... -
Integrating reCAPTCHA
Recently we've been looking into using reCAPTCHA for a form on the 2degrees site. We took a look at the python libraries out there and found that they either didn't meet our requirements or weren't sufficiently documented to allow a quick integration with our software. So, we've developed a couple of open-source libraries to allow easy communication with the reCAPTCHA service: python-recaptcha is an alternative to the client that google suggest. We've created a fully-tested and well-documented alternative which allows access to the whole API. The main advantage here, is the ability to access the different themes on offer. django-recaptcha-field is a small library which contains a factory for generating a Django form with a reCAPTCHA field in. All the other libraries we found worked around passing the client IP address to the reCAPTCHA service. Given that the API documentation states that this is a mandatory field, we've ensured that this is sent. If you have any suggestions for future improvement in these libraries, we'd love to hear from you. Of course, if you'd like to make the changes yourself you can always fork the libraries on github! -

Accessibility: Look at What's Out!
Overnight, my book on making accessible websites was released. It's my first book, and I'm completely over the moon. Not only do I get my own animal, but I get to put a book out on something I'm passionate about. I get to help break the paradigm that accessibility is too expensive, just about the blind, or only benefits a small portion of the population. Even better is the timing: I'm teaching a tutorial at DjangoCon on making accessible websites. I've been super jazzed about being able to do more than drive-by conversations with people about accessibility. It's one of those topics that many people approach with skeptisism, but leave with a budding interest. This time, I'll be able to take that interest and mold it into a deeper understanding in what it means to be accessible. We also get to improve a really bad restaurant site, which I think will be cathartic for most of us. There's space at the tutorial, so if you're at DjangoCon or in the DC area, you can still sign up! And heck, you can say you took a class on accessibility from the woman who wrote a book on it. -
Pushing a git branch
We're using git for most django projects now. There's one big problem I had: if I make a branch and want to push my changes to github, I sometimes get an error complaining that I'm behind on other branches so that my changes can't be pushed. The "solution" is to do a git checkout master, pull there (which updates my master pointer), and checkout back to my branch. Now I can push. This is pretty irritating. Why can't I just push the branch I'm working on? I found the solution on stackoverflow: git config --global push.default current This pushes only the current branch by default. Just what I wanted. -
Getting Started with Pinax Starter Projects
When I first started contributing to Pinax, one of the most exciting things to me was this idea of starter projects where you could be up and running with a certain type of a site literally within minutes. It was even more exciting to be able to shed having to build and maintain a lot of the infrastructure code around supporting project templates when Django started supporting the --template flag on django-admin.py startproject. We moved to having separate repositories for each of our starter projects and even these have the templates shipped separately with the notion of pluggable themes that are simply an app that you add to your requirements and INSTALLED_APPS. This is something James Tauber and I worked out rough versions of way back when we started KodeNode but with the breaking apart of Pinax this concept has really proven itself. Luke Hatcher has taken this idea to entirely new heights in building and maintaining an awesome theme, called pinax-theme-bootstrap based on Twitter Bootstrap. The old pinax.apps.account app has been completely rewritten by Brian Rosner and is more extensible than ever with some really incredible features as a stand alone Django reusable app called django-user-accounts. The starter project that I use for just about everything, combines django-user-accounts and pinax-theme-bootstrap to yield the pinax-project-account starter … -

Twitter Bootstrap and AJAX
As a long time web developer who has struggled with being comfortable with doing front-end development, having Twitter Bootstrap available is nothing short of transformative. The aspect that I am most enamored with is how much the bar has been lowered for guys like me to make relatively large UI changes without the need to segment work out to UI experts. However, I was writing the same bits of Javascript everywhere to do simply little things with $.ajax in jQuery. Code was fragile and often I would defer making the experience of doing some less polished/snappy because it would mean having to write some more of the same old Javascript that I was bored writing. "Ah, a POST followed by the 302 redirect isn't too bad, let's just roll with that for now...", I would say to myself. So, I created bootstrap-ajax.js. For the record, I don't think that all traditional form submissions followed by the standard 302 redirect are bad. In many cases it's exactly all that is needed and works well. You have to make the call for yourself and in the context of your own web apps what works best for each situation. What if we could break down the problem and … -

Performance metrics for a social network
This is a talk I gave at the Amsterdam Performance Meetup. The presentation starts by introducing Fashiolista. It still amazes me and 3 other guys started Fashiolista and grew it to the 2nd largest online Fashion community. I guess Marc Andreesen had a point in his “Why Software Is Eating The World” article. The talk focuses on how we use metrics to drive optimization at Fashiolista. And narrows down on tools like: NewRelic Graphite PgFouine If you’re looking up the links from the presentation, these are the most notable ones: Etsy on Statsd Instagram on PgFouine Fashiolista Jobs My Github Django Facebook The Presentation Performance metrics for a social network from Thierry Schellenbach Share and Enjoy: -

A Public Service Message to the Python Community
Hi, I'm Daniel Greenfeld. You might know me from my blog. I'm here to talk to you about a very import subject: Submitting your talk early to PyCon US. Last year there were hundreds of talks were submitted for just a very few speaking slots. Unpaid volunteers labored for hours before and after their normal jobs reviewing and debating which talks were to get in. The volume of talks combined with simple reviewer fatigue means that earlier submitted talks got more attention. This year, following the pattern of previous years, we're going to have 25% more talk submissions. Please don't leave your poor talk or tutorial out in the cold. Submit early. Help us fix the problem in one of two ways: Submit your talk as early as possible. Help review PyCon US talks. Production notes for this service message I've always wanted to do one of those TV public service messages done by B or C grade actors. As a D-grade blogger I thought I might be a pretty good match for the role. :-) -

DjangoCon and PyCon Canada
This fall I am venturing into the conference circuit starting with DjangoCon US in Washington DC, in September. I am definitely looking forward to seeing what it like to attend a major open source conference. I would also like to try to meet up with other Canadians making there way down to DjangoCon this year. Comment here or on find me on Twitter. Then in November in Toronto an excellent group of Python developers are launching PyCon Canada to help build community for 2014 when the official North American PyCon comes to Montreal. From the 9th the 11th of November in Toronto there will be a full fledged regional PyCon conference with talks, tutorials and sprints. Registration is open and they are accepting speaker applications. The next obvious step will be to plan a conference of my own. -
Sphinx Doc, JSON highlight and Sphinx extensions: kung-fu
At the moment Pygments which used by Sphinx Doc haven't support for JSON code highlight which is really sad.I've not found any useful information how to do it quickly.

I will be part of pygments soonIt wasn't clear to me how to add custom pygments lexer to sphinx, my google-fu isn't good todayA bit more googling gave me Sphinx Extensions API , especially add_lexer method of Sphinx instance Ok, now it's clear to me how to add new lexer. I've created ext/hijson folder within source, to __init__.py I've added setup function: Also here is how to add support of ext folder as folder with custom extensions So, pip install pygments-json and use .. code-block:: json Nice and smooth: -
How to Easily Add Referrals to a Website
Referrals are a popular and very effective way to generate quality traffic while allowing users that love your site to become promoters. We built anafero because we were increasingly wanting to deploy referral systems on more of our sites as well as sites for some of our clients. Multiple Uses There are multiple ways that anafero can be used. We have used anafero specifically in these various contexts: Generate one referral per user and just display a simple number to them to show how many responses they have generated. Setup of specific activities that you want to track and report to the referring user (e.g. not just that respondents clicked on the link but that they signed up as well). Allow users to generate their own referrals, naming them, so that they can track different channels and what methods of promoting the site are working for them. Let users use generated referral links to act as semi-private share links that unlocks private content for the visitor but only when they get to the site using the private referral link. Setup thresholds that when a referring user surpasses certain goals they receive an award. This is what we are doing on Gondor (you can see … -

Taking command
Commands are the bread and butter of any game. Commands are the instructions coming in from the player telling the game (or their avatar in the game) to do stuff. This post will outline the reasoning leading up to Evennia's somewhat (I think) non-standard way of handling commands.In the case of MUDs and other text games commands usually come in the form of entered text. But clicking on a graphical button or using a joystick is also at some level issuing a command - one way or another the Player instructs the game in a way it understands. In this post I will stick to text commands though. So open door with red key is a potential command. Evennia, being a MUD design system, needs to offer a stable and extensive way to handle new and old commands. More than that, we need to allow developers pretty big freedom with developing their own command syntax if they so please (our default is not for everyone). A small hard-coded command set is not an option.Identifying the commandFirst step is identifying the command coming in. When looking at open door with red key it's probably open that is the unique command. The other … -
Django Requirements 2012-08-15
A little over three months ago I blogged about my preferred requirements list. It's now nearly the eve of Django Dash, and I feel it's time to update the list. I'm going to bump the versions on some of the existing packages and add some new ones to the list. New Packages django-braces==0.1.3 Want to use Django Class Based Views but unhappy with the missing components like LoginRequiredMixin, SelectRelatedMixin, and even StaffuserRequiredMixin? Not to worry, as this library will make Django CBVs 134% easier to use. django-secure==0.1.2 Django is rather secure, but there is a checklist of things that the security experts want you to do. Save yourself forgetting something and use this library to do all those little things. django-profiletools==0.1.3 Have you ever used the django-debug-toolbar and noticed that you did that same request.user.get_profile() call a dozen times? Ever want to just call that once? This library, by yours truly, resolves the issue. It loads the user's profile object once, and then passes it down the request chain. Existing Packages Django==1.4.1 If you need sessions, forms, templates, and relational database models, then I can argue you've got the ideal Django project. Make certain you are running the latest Django … -
