Python - Favorite Django Tips & Features. Context processors are awesome.
Say you have a different user model and you want to include that in every response. Instead of doing this: def myview(request, arg, arg2=None, template='my/template.html'): ''' My view... ''' response = dict() myuser = MyUser.objects.get(user=request.user) response['my_user'] = myuser ... return render_to_response(template, response, context_instance=RequestContext(request)) Context processes give you the ability to pass any variable to your templates.
I typically put mine in 'my_project/apps/core/context.py: Django_session. Django_User.
- Luc Stepniewski's Blog. In a Django project, I have a template that is used by two urls, which is quite common (generic views, using ‘create_object’ and ‘update_object’).
The problem is that I had to add a supplementary menu just when the template is loaded from the ‘update’ generic view, and not from the ‘create’ generic view. Making the difference between the two urls calls at the template level is a problem because it’s managed by generic views, so the same template is used. Anyways, there are several possibilities: In urls.py, use the ‘template_name’ variable, where you can speficy a specific template for this url(). That is instead of using the default <model>_form.html. Pinax : Package List.
Django_cron. Confusion in Django admin, static and media files. Static files are files needed by your applications that server can serve without modifications, like custom JS scripts, icons, applets, etc.
The best way to use it is to place static files in a "static" folder in each of your app's folder. Like this, the test server will find them there, and if you deploy on a production server, you'll just have to run python manage.py collectstatic to copy them all in the root static folder defined in you settings.py Media files are those uploaded by the users of your applications, like avatar's pics, etc.
Django_rails. Django_restful. From Designer to Django’er in Six Weeks — djangocon-2011-notes v0.0.1 documentation. Django. A Guide to Testing in Django - Toast Driven. For many people, testing their Django applications is a mystery.
They hear that they should be testing their code but often have no clue how to get started. And when they hit the testing docs, they find a deep dive on what functionality is available, but no guidance on how to implement.
Django_form. Django_ajax. 10 Insanely Useful Django Tips. There are quite a few great little tricks and tips one could use on their Django projects that would speed up development and save many headaches in the long run.
From basic to obscure, these tips can help any skill-level of programmer become more adept with Django and all it's glory. Django is an excellent framework for Python. While it may not get as much ink as other popular frameworks like Rails, it is just as much a polished framework as any of the rest. It puts plenty of emphasis on the DRY principle (Don't Repeat Yourself) in clean coding by automating many of the processes in programming. For some reason, projects tend to be moved around in location from time to time. My default Django settings file has changed over time to now include settings that do not depend on the location of the project on the file system. Tutorials. Django Projects — Django Best Practices. Location Templates typically live in one of two places, inside the application or at the root level of a project.
We recommend keeping all your templates in the project template directory unless you plan on including your application in multiple projects (or developing it as a open source “reusable” application). In that case, it can be helpful to ship with a set of sample templates in the application, allowing it to work out-of-the-box or serving as an example for other developers. Naming Django’s generic views provide an excellent pattern for naming templates. They have been well thought out and tested.It makes your code immediately understandable to new developers picking up your Django code. Most generic view templates are named in the format: [application]/[model]_[function].html. How and why to use django-mongokit (aka. Django to MongoDB) Here I'm going to explain how to combine Django and MongoDB using MongoKit and django-mongokit.
MongoDB is a document store built for high speed and high concurrency with a very good redundancy story. It's an alternative to relational databases (e.g. MySQL) that is what Django is tightly coupled with in it's ORM (Object Relation Mapping) and what it's called now is ODM (Object Document Mapping) in lack of a better acronym. That's where MongoKit comes in. It's written in Python and it connects to the MongoDB database using a library called pymongo and it turns data from the MongoDB and turns it into instances of classes you have defined. So we start by defining a MongoKit subclass: All of these class attributes are features of MongoKit. As you can see it's pretty easy to work with and it just feels so pythonic and obvious. The query methods one() and find() can take search parameters which limits what you get back.

I've Googled, but have not found any really organized and layman-friendly overview, which is why I came here.
I know how to get python/django working on my computer (PC or Mac) and have developed simple test apps using django's built-in dev server and a mysql back-end. So I can get things to work and don't need help on installing stuff. But as a coding hobbyist, I don't know how to set up a pro workflow. I don't know best practices on how to setup and maintain a dev and production environment, how to efficiently publish to production, how to integrate all that into a version control system (i.e., git), basically anything that a pro coder at a startup would take for granted as "the way to do things". The Django Book: Version 2.0 (English) Five Days to a Django Web App: Day Three, Coding - The Daily Build. Thanks for coming back for Day Three!
[Note: Sorry this post is a day late. It was all ready to go late yesterday, but some of the code included below triggered a bug either in WordPress or ScribeFire and the whole post got mangled. I managed to resurrect it today from drafts, and I think it's coherent, but if you find some problem with it please drop me a note.] Progress So Far Yesterday we built some mockups, just HTML and CSS — nothing active. Armed with these mockups, we’re ready to get started coding. Foundation MySQL First, go to your web host’s control panel and create two MySQL databases for this project.
You’ll get an error/warning if the test database exists when you first run tests. Set up the same databases on your local system: bash$ mysql -u root Welcome to the MySQL monitor. Documentation de Django — Documentation de Django 1.1.1. Index — Django Design Patterns. This is a collection of patterns which we have found occurring commonly with Django.
All of these either make collaboration easier, coding simpler or code more maintainable. None of them are design patterns in the sense of GoF design patterns. We call them design patterns as none other seem closer or more convenient. These are guidelines, which need to be overridden (very commonly, in some cases). Use your judgement when using them.
