In our Introduction to Django, we covered all the basics of using the open source web-building framework. If you haven’t read through our beginner’s tutorial, go ahead and do so now. If you’ve already made it through the easy stuff, you’re probably ready to dive into some code and start building — so let’s do it.
Last time around, we installed Django and started building a blog application. We got Django’s built-in admin system up and running and explored some third-party libraries like the django-tagging project.
So far we have some cool administrative tools, but no website for the rest of the world to see. This time around, we’ll work on displaying our content to the world by building the URL patterns and constructing some “views” — a term with a very specific meaning within the Django framework.
Everything we’re going to do will make more sense if you understand how Django processes your visitor’s request. We went over some of this in our introduction, but here’s a quick refresher course.
This is part 4 of Webmonkey’s introductory Django tutorial. If you’re arriving here to learn about getting started with Django, start back at the beginning with Lesson 1.
When we left off last time, we had defined some URLs for our blog and constructed a custom view to handle displaying posts by tag. If you point your browser to our development URL at this point, (http://127.0.0.1:8000/blog/) you’ll still see a Django error page complaining that the template blog/list.html does not exist. Don’t panic, it’s true — we haven’t created it yet.
It’s time to tackle the last aspect of Django, the template syntax.
Popular Ajax library jQuery is celebrating its fourth birthday with a major new release — JQuery 1.4.
The latest version of jQuery boasts some impressive speed gains and represents a ground up refactoring of much of jQuery’s underlying code. According the jQuery’s developers this release is significantly faster across browsers and eliminates much of the redundancy in jQuery’s internal functions.
Other nice changes in this release include support for HTML5 elements in serialization calls, the ability to test for specific rendering engines (for example, target WebKit with jQuery.browser.webkit) and support for per-property easing in your animations.
