From static to realtime - Eric Florenzano (djangocon.eu)
Note: Eric is one of the founders of convore (see the djangocon eu 2011 group on convore). His talk is on converting a django site to the realtime age: does the django heart stay in place or is it replaced with something "more current" like node.js? In the end, he told his story as a fairy tale. Entertaining and slick. Good job! At a certain time he thought about writing a shiny new social photo website. All the cool sites were about social photo stuff. So he build one. And it became popular! And slow. So caching to the rescue. It helped. For a while. It became even more popular. Social photos mean frantic reloading of webpages. So it became slow again. Full-page reloads. Even expiry headers didn't help. Good artist copy, great artists steal. So he stole some ideas from twitter. Just a quick json endpoint that listed the most recent photos. And a bit of javascript that reloads that small bit of content every five seconds. If something has changed, a button would pop up so the user could reload. The users loved it. But every user that visited any page on the site would keep hitting that … -
Opening - Remco Wendt (djangocon.eu)
Opening of the third European Djangocon! Remco tells us to behave as there's a java island (java-eiland in Dutch, see photo below) 200m from the conference location. So if you write non-clean code during the sprints you'll be banished to this prison island :-) Nice to see our (Nelen & Schuurmans) company name right there on the left hand side on one of the big sponsor banners, btw! The question everyone is about to ask: yes, the wifi is holding up nicely :-) Warning: the public transport in Amsterdam is on strike on tuesday. Good thing that the city of Amsterdam sponsors us with free bikes for the duration of the conference. On wednesday there are bitbucket-sponsored drinks. Also several other people have been invited from tech companies in Amsterdam and from ruby/js/etc. On hashtags: on twitter, look at #djangocon. -

Preparing for djangocon (djangocon.eu)
It is sunday evening and tomorrow morning I'm going to Amsterdam for the djangocon.eu conference. I'm staying at home at night as it is close by enough. It'll mean less night rest than I'm normally getting at a conference, as I'll have to subtract a one one-way hour commute (two hours total) from every conference day's night rest. A big part of a preparation for me means preparing my talk summaries. Last year I wrote a metric buttload of summaries and this year I'm going to do the same. This does mean looking up all the talks beforehand and preparing a text file on each and every one of them. With a link to the project readily pasted in and a proper reference to the author. And an photo pasted in. I want, somehow, to have a photo for every entry. Normally I take photos in the conference town and at the conference, but I don't stay in Amsterdam itself, so I won't have much chance at making photos. Only of the station and so. So what about model train photographs? Not a bad idea at all :-) I've got a lot of photos of excellently modelled railways. Not the … -

DjangoZoom.com Review
This is part five in my series on django hosting services. Previously, I looked at ep.io, apphosted.com, gondor.io, dotcloud.com and now I'm looking at DjangoZoom.com. DjangoZoom.com is the brain child of Nate Aune and Shimon Rura and is based in Boston, Massachusetts. It was founded in 2010 at StartupWeekend Boston and was a finalist in the MassChallenge. Their office is in the Dogpatch Labs space for startups in Cambridge, Massachusetts. They are currently still in a closed beta, but they were nice enough to send me an invite to check it out. Normally when I check out a service for the first time, I look over the documentation to see what it can do, and what it can't do, and what I need to do in order to get my app up and running. DjangoZoom has a nice collection of documents that help guide you through the process of getting your application up and running on their platform. You need to be logged in, in order to read the documents, so I won't be able to link to any documents here, but if you are lucky enough to get an invite to DjangoZoom, I would check out the documents first, … -
Django-urlcrypt, après les contes c’est l’url de la crypte.
Voila, comme dit dans le billet précédent, je vais donc faire deux billets de django app de mai, ça m’apprendra à être en retard. Donc la deuxième django app du mois sera django-urlcrypt. Une petite précision avant d’aller plus loin, c’est une des toutes premières fois où je vais parler d’une app sans avoir fait plus que la tester sur un projet de test, sans avoir d’idée précise de où ni comment je vais l’utiliser ‘en vrai’. 1- Où on le trouve, comment on l’installe, tout ça quoi (et la doc) ? Alors on le trouve soit sur sa page pypi soit sur sa page github. Pour l’installation là encore, les trois moyens habituels : par easy_install pip un petit git clone des familles La doc, là c’est comme l’app précédente, elle est limitée au contenu de la page de pypi ou au fichier Readme.rst. Bon alors c’est vrai que la doc est suffisante pour comprendre comment l’app marche, mais sur une app qui est aussi ‘sensible’, une bonne lecture du code ne fait pas de mal (c’est d’ailleurs ce que j’ai fait quand j’ai commencé à faire joujou avec). 2- Mais au fait, à quoi ça sert ? En … -
Django-countries ,l’app garantie sans cowboy ni rodéo. djangoApp de mai 1 sur 2
Il va falloir que je me surveille .. parce qu’encore une fois je publie ma django app du mois un peu en retard. Pas grand chose, juste 4 jours.. Mais ça commence comme ça et après on finit par ne plus tenir de rythme du tout. Du coup, pour marquer, le coup, je publierais deux django app du mois de mai, même si je les publie en juin. Et pour commencer, django-countries. C’est d’ailleurs assez rigolo parce que je parlais il y a peu de moyen de gérer les pays, avec une liste de choix existantes, etc.. et op, je tombe sur django-countries. 1- Où on le trouve, comment on l’installe, tout ça quoi (et la doc) ? Vous trouverez django-countries soit sur sa page pypi soit sur sa page bitbucket. Pour l’installation, vous avez les trois moyens désormais classique : un easy_install un pip install un bon vieux hg clone La doc elle se limite à : la page pypi le readme du repository Sachant que dans les deux cas, le contenu est le même. Mais vu la simplicité de l’app, cela suffit amplement. 2- Mais au fait, à quoi ça sert ? L’app rajoute tout simplement un nouveau … -

Wordpress to Django: Designing Compatible URLs in urls.py
As I mentioned in my previous post, there are a few fairly easy strategies for maintaining the stable URLs for your content when migrating from WordPress to a local Django driven blog. Django allows you a high level of control over URL formats so it's fairly simple to design them to be compatible with WordPress URLs. Additionally WordPress has been around long enough that the standard URL re-write formats follow suggested best practices for content, so bringing your Django URLs in alignment with that is not only useful for migrating content but good practice overall. That said the two most common formats for URLs in WordPress are: http://<domain>/<4 digit year>/<1 or 2 digit month/<1 or 2 digit day/<slug>/ so for example the URL for the previous post linked above is... http://www.flagonwiththedragon.com/2011/06/01/wordpress-to-django-strategies-dealing-with-WordPress-querystring-urls/ The next most common format for URLs is similar and differs mostly in how months are abbreviated: http://<domain>/4 digit year>/<3 char month>/<1 or 2 digit day>/<slug>/ So an example of the same URL above in this format would be... http://www.flagonwiththedragon.com/2011/jun/01/wordpress-to-django-strategies-dealing-with-WordPress-querystring-urls/ Designing urls.py in Django to accomodate this is simply: # URL format where month format is abbreviated character format. url(r'^(?P\d{4})/(?P\w{3})/(?P\d{1,2})/(?P[0-9A-Za-z-]+)/$', 'post_detail_alt'), url(r'^(?P\d{4})/(?P\w{3})/(?P\d{1,2})/$', 'post_day_alt'), url(r'^(?P\d{4})/(?P\w{3})/$', 'post_month_alt'), # URL format where … -
Getting prepaid mobile internet in NL
Getting prepaid mobile internet in NL UPDATE: when you register for the extra € 5 credit on My Vodafone, enter a (fake) Dutch address. One attendee was refused for registration when entering a foreign address, and was then refused for registration because his number was supposedly already registered. Coming to DjangoCon from abroad? Mobile roaming is usually expensive, so if you want to use internet on your phone, it’s best to get a Dutch prepaid SIM card. For € 7.50, you can get 1 GB data. Tethering is technically not allowed, but they probably don’t actively check for this. The only option with acceptable pricing are two different SIM types from Vodafone. Note: I have not tested these instructions myself. Use them at your own risk. This is all based on the Dutch Vodafone website. If you find any issues with them, please let me know :) What to buy Buy either one of these SIM cards: Vodafone Prepaid SIM only Meerwaarderen (€ 7.50). This includes € 10 credit but does not include any data. Not available in microsim. Vodafone Prepaid Smartphone Sim Only 1GB (€ 20). This includes € 10 credit and a 1 GB data package. Also available … -

Django "view-permissions" for related objects
You have a model A with a relation to another model B. In the Django admin, you have full permissions for model A and none for model B. However, if you create a new object for model A, you need to select a related object from model B. Tough luck: Permission denied! -

Using the Django-Pagination app in Django 1.3
Like many Djangonaughts I use django-pagination as my primary means to page results on lists pages and between the differences on the original Google project page(1.0.5 is the last downloadable version), what appears to be the same project migrated to GitHub and the PyPi (1.0.7 is the pip install version) site for the project, things can get confusing. I'm probably the only person confused by this but it appear that the GitHub site is the most up to date and it appears to be in sync with the pip install version. Life signs overall are dubious on the project though with no updates having come since early 2010 and several (what seem to be) reasonable pull requests sitting in the project queue. One gotcha I wanted to point out in the PyPI readme file is the directions for TEMPLATE_CONTEXT_PROCESSORS: According to the project documentation, in settings.py you should set: TEMPLATE_CONTEXT_PROCESSORS= ( "django.core.context_processors.auth", "django.core.context_processors.debug", "django.core.context_processors.i18n", "django.core.context_processors.media", "django.core.context_processors.request" ) This can cause some problems in Django 1.3 however since the default TEMPLATE_CONTEXT_PROCESSORS have changed, in particular to support the new features for serving static media. So to include for pagination to work and to keep the default template context processors you should instead set: … -

Test static resources in Django tests
At Mozilla we use jingo-minify to bundle static resources such as .js and .css files. It's not a perfect solution but it's got some great benefits. One of them is that you need to know exactly which static resources you need in a template and because things are bundled you don't need to care too much about what files it originally consisted of. For example "jquery-1.6.2.js" + "common.js" + "jquery.cookies.js" can become "bundles/core.js" A drawback of this is if you forget to compress and prepare all assets (using the compress_assets management command in jingo-minify) is that you break your site with missing static resources. So how to test for this?[367 more words] -
