Django Forms I: Custom fields and widgets in detail
On Thursday September 8th I copresented with Daniel Greenfeld my first talk “Advanced Django Form Usage” at DjangoCon.us 2011. It was my first talk for many reasons. I had never spoken in front of such a large audience before, less in English and this was also my first Python talk. If you haven’t seen the video of the talk and the slides, you probably want to, because this post will try to extend, clarify and recap it somehow. Also this will be my official erratum for things that were not exactly true or right that appeared in the slides Some people really loved the talk and came after it to comment it with me and ask some questions. By that time, I was already thinking that the topic did deserve its own series of posts. Gabriel Hurley, Django committer and documentation specialist, stated: Apparently some core developers were asking to use the code examples and a transcript from the talk as a starting point for this task. Well, I wasn’t sure if the transcript would be good enough, many things were left to say, but I agreed with Gabriel that it’s a good starting point to base docs on, which … -

Streamline your Django workflow
This post is about a couple of improvements I made to my Django development environments recently. It started with a simple issue. Whenever I want to work on something, I need to: Run the Django development server, Run compass watch on my CSS files, Run the command that automatically runs my tests when a file changes in the project. That's 3 terminal windows to open (I don't use tabs :) and twice as much commands to type. Tedious, to say the least. Luckily a friend / colleague of mine, Bertrand, pointed me to a tool to manage such repetitive tasks: Foreman. To quote their documentation: Foreman is a tool to manage Procfile-based applications. Which means (for us), it reads a file that describes different processes and runs them in parallel, merging the output of every process. First, let's install the gem. Making gems play nice with virtualenv If you like virtualenv, you'll probably don't want to install ruby gems system-wide. To tell gem to install stuff in your virtualenv, just add: export GEM_HOME="$VIRTUAL_ENV/gems" export GEM_PATH="" export PATH=$PATH:$GEM_HOME/bin to your ~/.virtualenvs/postactivate hook. Now you can gem install stuff and it'll be isolated from your system. As a side note, gem compiles … -

Integrating the flask microframework with the peewee ORM
I'd like to write a post about a project I've been working on for the past month or so. I've had a great time working on it and am excited to start putting it to use. The project is called flask-peewee -- it is a set of utilities that bridges the python microframework flask and the lightweight ORM peewee. It is packaged as a flask extension and comes with the following batteries included: Admin interface a-la django RESTful API toolkit a-la tastypie Authentication system The documentation provides in-depth explanations on the usage of these features, but if you are already familiar with django things shouldn't look too strange. The purpose of this post will be to highlight the main features of the project and discuss a little bit about their implementation. Admin interface Users of the django framework often say how valuable the admin interface is. It is, for many site managers, their primary means of interacting with django-powered sites, and for developers it is great for rapid prototyping. Considering this, one of the first things that bit me when I started working with flask was that there was no admin interface. Several times I've stopped a project before it … -
Beating Google With CouchDB, Celery and Whoosh (Part 1)

DjangoMaine.com - Django User group in Portland Maine
When I was at DjangoCon a few weeks ago, it was great hanging out with all of the fellow Djangonauts talking about Django and all of other great technologies. Now that I'm home, I have decided to get off my butt and do something I should have done a while ago. Without further ado, I am pleased to announce the creation of DjangoMaine.com, a new Django user group based in Portland Maine. We plan on meeting monthly to discuss Django and other python related technologies. We are currently looking for members, and topic ideas for future meetings. If you have any ideas or you are interesting in hearing more, check out our website http:///www.DjangoMaine.com -

Tmux scripting
I usually need to run more than 1 command for some project and got tired of searching through those putty windows for the session I want. So I thought of using a terminal multiplexer like Tmux. I’m using celery with two queues and I need to run this: manage.py celeryd -Q queueA manage.py celeryd -Q queueB manage.py celerycam -E I need celerycam because it will get those stats in djcelery up to date. It’s also a good idea to tail the postgresql log – when you break your models or database in some cases Django isn’t very helpful so this helps a lot: tail -f /var/log/postgresql/postgresql-8.4-main.log I use a wide screen so I want a layout like this: +------------------------------------+-------------------+ | | | | runserver | | | | celerycam | +------------------------------------+ | | | | | celeryd +-------------------+ | | | +------------------------------------+ | | | postgresql log | | celeryd | | | | | +------------------------------------+-------------------+ I also want to start a new tmux session from the same command so I can close everything easily – those celeryd’s don’t reload automatically :( You’d usually run something like: tmux new-session "tmux splitw 'command1'; tmux splitw 'command3'; tmux splitw 'command3'; command4" but … -

Profiles: Breaking Normalization
In the summer of 2010 I either saw this pattern or cooked it up myself. It is specific to the Django profiles system and helps me get around some of the limitations/features of django.contrib.auth. I like to do it on my own projects because it makes so many things (like performance) so much simpler. The idea is to replicate some of the fields and methods on the django.contrib.auth.model.User model in your user profile(s) objects. I tend to do this usually on the email , first_name , last_name fields and the get_full_name method. Sometimes I also do it on the username field, but then I also ensure that the username duplication is un-editable in any context.Sure, this breaks normalization, but the scale of this break is tiny. Duplicating four fields each with a max of 30 characters for a total of 120 characters per record is nothing in terms of data when you compare to avoiding the mess of doing lots of profile-to-user joins on very large data sets.One more thing, I've found that most users don't care about or for the division between their accounts and profiles. They are more than happy with a single form, and if they aren't, … -
Django Facebook 2.0 – Integrating Facebook
Django Facebook 2.0 – Integrating Facebook.

Könnte gerade zusammen mit der neuen Timeline von Facebook wieder interessant werden. Und G+? Naja, solange die nur armselige Spar-APIs liefern, ist das für Bastler schlichtweg uninteressant. -

Petit resum d'estiu
Fa un grapat de setmanes que no escric res a aquest blog, tenc moltes coses pendents, però entre unes coses i altres el temps va passant i fins avui no he trobat una estona per a tornar-hi. Han estat unes setmanes molt estranyes: problemes personals, alguns bons, com les noces de la germana i altres no tan bons, molta feina i com no, el començament de l'escola dels menuts i la festa de la Vermada que ja és aquí. En el terreny de la feina tenc dues bones notícies: hem posat ja en producció un projecte que em fa una especial il·lusió txerpa i una web presencial fiscontrol. txerpa és un projecte que hem desenvolupat per a una coneguda gestoria/assessoria de l'illa. Integra una web, un backoffice per a la gestió d'empreses via OpenERP i la integració amb el mateix OpenERP de manera que es poden crear molt fàcilment instàncies personalitzades per a poder dur una comptabilitat i gestió. El projecte des del punt de vista tècnic ha estat molt engrescador. És un projecte amb un llarg recorregut en el qual esperam poder-hi afegint millores i nova funcionalitat. L'interessant, però, és veure que des d'aquestes illes nostres iniciatives com aquestes … -
