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 :)

Automatic urls for static pages

Create in your template dir html files named example.static.html and with this snippet you can get the static page with the url /example/. If you put static file in a sub-directory, the url will be /sub-directory/example/ **Example:** `static_urls = StaticUrls()` `urlpatterns = patterns('', *static_urls.discover())` `urlpatterns += patterns('',` `(r'^admin/doc/', include('django.contrib.admindocs.urls')),` `(r'^admin/', include(admin.site.urls)),` `)`

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.

Decorating URL includes

Apply a decorator to every urlpattern and URLconf module returned by Django's include() method . This allows you use a decorator on any number of views without having to decorate each one individually. The use case here is wrapping all of the Django Admin with a superuser decorator. This is code that's better left alone where we can't actually go in and decorate the Admin views and urlpatterns manually. It's also almost guaranteed the Admin will include() other URL files. So the added bonus is all the INSTALLED_APPS that have their admin.py files registered by admin.autodiscover() will be decorated automatically as well. This snippet is greatly inspired by [@miracle2k](http://djangosnippets.org/users/miracle2k/)'s excellent [#532](http://djangosnippets.org/snippets/532/). In the comments there @timbroder offers a modification to decorate includes but I think this is cleaner, simpler code and not subject to changes in the Django base code driving _get_url_patterns().

Simple views dispatcher by http methods

Calls a view by request.method value. To use this dispatcher write your urls.py like this: urlpatterns = pattern('', url(r'^foo/$', dispatch(head=callable1, get=callable2, delete=callable3)), ) If `request.method` is equal to head, `callable1` will be called as your usual view function; if it is `get`, `callable2` will be called; et cetera. If the method specified in request.method is not one handled by `dispatch(..)`, `HttpResponseNotAllowed` is returned.

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!

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.

Generic object_detail view filterable by multiple url values

This view acts as an extension to the object_detail generic view in django.views.generic.object_list. The standard generic view can only filter the queryset by object_id or slug; this view allows you to filter by any parameter you like, as well as multiple parameters. The usage is the same as the standard object_detail view except that you must also give the parameter 'filters', which should be an array of what you would like to filter the url values as, and instead of 'slug' or 'object_id' as the regex parameter in the URL, use 'value1', 'value2', etc. Example: If you have a list of companies, each with multiple branches, you may want a branch details page. A URL for this may look as follows: http://www.mysite.com/company/company-slug/branch-slug/. To implement this simply use the urlpattern example give,

URL models

You can use `UrlModel` to provide URL functionality to any instance of any model and any language (language support can be removed from this). Each model must have own view method, that returns HttpResponse. I was inspired by Flatpages. It is useful for small sites and static pages. `class Page(UrlModel): text = models.TextField() def view(self, request) # do something here return HttpResponse(...)`

@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.)
