@url decorator improvements

A slight modification (and, I think, improvement) of the URL decorator found in [snippet 395](http://www.djangosnippets.org/snippets/395/). What's different between this snippet and 395? 1. We use `django.conf.urls.defaults.url()` when adding patterns 2. We support arbitrary arguments to the `url()` method (like `name="foo"`) 3. We _do not_ support multiple url patterns (this didn't seem useful to me, but if it is I can add it back.)

Row-Level, URL-based permissions for FlatPages

I'm using Django's FlatPages, but I want to be able to restrict admin access to Users based on a FlatPage url. For example, User John Doe should be able to edit any FlatPage objects whose URL begins with `/johndoe/` (such as `/johndoe/about/` or `/johndoe/projects/whatever/`). For this to work, John Doe would already need the appropriate admin permissions for FlatPage (such as can_add and can_change). I have set this up as a separate *flatpage_addons* app. It consists of the **Permission** model, which maps a starting URL to one or more django Users. It consists of the minimal necessary admin code so Permissions can be created using the admin. The bulk of this code consists of the *ifhasflatpagepermission* template tag as well as the *flatpage_result_list* inclusion tag. The former works much like django's existing *if*, *else*, *endif* tags while the latter is modified from the django admin's *result_list* inclusion tag. This may not be the most elegant solution to my problem, but so far it works for me. Any comments or suggestions are welcome!

Overwrite some views in settings.py

If you app defines some URLs with a name, and you want to overwrite this at project level with a different view you can use this snippet. You only need to change on line in the application code (the import statement).

Ajax form with jQuery

I recently got a form working via jQuery and Django. This was not easy for me to do and I thought I'd record my finding here. The form submits via jQuery and the "form" plugin. Please visit jQuery's home page to find all those links. This code handles: * urls.py -- passing both normal and 'Ajax' urls to a view. * views.py -- Handling both kinds of requests so that both normal and ajax submits will work. * The HTML template with the script for submitting and some bling. Error handling === I like to stay DRY so the idea of checking the form for errors in javascript *and* checking it in Django irks me. I decided to leave that up to Django, so the form submits and gets validated on the server. The error messages are sent back to the browser and then displayed.

Decorating urlpatterns

One thing I wanted for a while was the ability to basically apply something like @login_required to a bunch of urlpatterns in one go, instead of having to decorate each and every view manually. In this example, the latter two views will always raise a 404.

Using reverse() to do redirects

When I initially set up my blog, I put together the archives with URL patterns like so: * `/weblog/2007/` goes to `archive_year` * `/weblog/2007/08/` goes to `archive_month` * `/weblog/2007/08/24/` goes to `archive_day` * `/weblog/2007/08/24/some-slug` goes to `object_detail` The same patterns held for links, only the prefix was `/links/` instead of `/weblog/`. For a forthcoming redesign/rewrite, I'm switching to using abbreviated month names (e.g., "aug", "sep", "oct", etc.) in the URLs, which means I need to redirect from the old-style URLs to the new. This snippet is the solution I hit upon. Two things are notable here: 1. Each one of these views uses [reverse()](http://www.djangoproject.com/documentation/url_dispatch/#reverse), called with the appropriate arguments, to generate the URL to redirect to. This means URLs don't have to be hard-coded in. 2. Each view takes an argument -- `object_type` -- which is used to generate the view name to pass to `reverse`, meaning that only one set of redirect views had to be written to handle both entries and links. This is just one of many handy tricks `reverse` can do :)

Never cache a group of URLs

This is a special URL patterns replacement that prevents caching of any URL listed within it. We needed this in Review Board to prevent the JSON API function results from being cached in Internet Explorer.

Localized URLs (www-en)

An example on how we changed our localization middleware to use www-en.<domain> instead of it being hidden in the cookie. This also changes zh-cn to cn, and zh-tw to tw in the URLs. This is only a base snippet and you will most likely need to modify it to fit your needs.
