A URL field specifically for images, which can validate details about the filesize, dimensions and format of an image at a given URL, without having to read the entire image into memory. Requires [Python Imaging Library](http://www.pythonware.com/library/pil/). *4th October, 2008* - updated for 1.0 compatibility.
The {% url %} templatetag is awesome sometimes it is useful to get the full blown URL with the domain name - for instance for links in emails. The **{% absurl %}** templatetag mirrors the behaviour of {% url %} but inserts absolute URLs with the domain of the current Site object. Usage: {% absurl viewname %} >>> http://www.example.org/my/view/
An example of using it in your settings.py: MIDDLEWARE_CLASSES = ( 'django.middleware.common.CommonMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.middleware.doc.XViewMiddleware', 'util.loginmiddleware.RequireLoginMiddleware', ) LOGIN_REQUIRED_URLS = ( r'/payment/(.*)$', r'/accounts/home/(.*)$', r'/accounts/edit-account/(.*)$', ) In a nutshell this requires the user to login for any url that matches against whats listing in LOGIN_REQUIRED_URLS. The system will redirect to [LOGIN_URL](http://www.djangoproject.com/documentation/settings/#login-url)
The rationale behind this decorator is described in django-users google group. Usage: === urls.py === urlpatterns = patterns('', (r'^', include('apps.app1.views')), (r'^app2', include('apps.app2.views')), ) === apps/app1/views/__init__.py === @url(r'^index/$') def index(request): ... @url(r'^news/$') def news(request): ... urlpatterns += include_urlpatterns(r'^members', 'apps.app1.views.members') === apps/app1/views/members.py === @url(r'^profile/$) def profile(request): .... @url(r'^secure/$) def secure(request): ... @url(r'^path1/$', '^path2/$') # you can specify several patterns def multipath_view(request): ... def helper(): # easily distinguishable - no @url! ... Summarizing, the benefits are: * no more creating and supporting urlpattern maps (less files, less code, more DRY) * have the url associated with a view in-place * easily see if a function is a view * fully compatible with other chained decorators
This is an example middleware that is highly inspired by how Symfony handles [i18n in URLs](http://www.symfony-project.com/book/trunk/13-I18n-and-L10n#Changing the Culture for a User). You basically set a (?P<dj_culture>[\w-]+) pattern in your URL and this middleware will determine the language to use for the i18n toolkit for Django. It also removes the dj_culture parameter after dealing with it, so that you don't have to change all the views you want this middleware to work with.
Simple code , judge login require by url
with this you can have context variables which know the media url and the urls of all your applications, if you need it. save the code as myapp/context_processors.py and add the following line to `TEMPLATE_CONTEXT_PROCESSORS` setting "mysite.myapp.context_processors.url_info", For each application you need to know the url set `MYAPP_URL` and add it to dict.
Add this to your model to be able to get their admin change link from anywhere Useful if you want to jump to the admin screen of an object you are looking at on the front end
This snippet suplies a resolve_to_name function that takes in a path and resolves it to a view name or view function name (given that the path is actually defined in your urlconf). Example: === urlconf ==== urlpatterns = patterns('' (r'/some/url', 'app.views.view'), (r'/some/other/url', 'app.views.other.view', {}, 'this_is_a_named_view'), ) === example usage in interpreter === >>> from some.where import resolve_to_name >>> print resolve_to_name('/some/url') 'app.views.view' >>> print resolve_to_name('/some/other/url') 'this_is_a_named_view'
Modify a query string on a url. The comments in the code should explain sufficiently. String_to_dict, and string_to_list are also useful for templatetags that require variable arguments.
You can import get_admin_url into your models module and create a property on a class: `admin_url = property(get_admin_url)`
Sometimes you need to make redirects that involve domains, you can't define those on the site urls, this middleware lets you define multiple redirects on your site settings. Note: *You also can use the web server to do this, but I have found this middleware a useful tool to quickly or temporarily define redirects*. Depending on your needs you may also find useful [snippet 434](http://www.djangosnippets.org/snippets/434/).
#### this is the right and working way
I created this template filter to be able to use get_absolute_url in an email template. Save the code into /templatetags/navigation.py Use like this: {% load navigation %} {{ instance.get_absolute_url|siteabsoluteurl:request }}
A template tag that includes a modified version of the GET query string. the query string can be manipulated by adding and removing fields. If a value is given that resolves to a context variable that the value of the variable is used. Based on [this snippet by dnordberg](http://djangosnippets.org/snippets/826/), but with the ability to use context and done in a cleaner manner, without the need to add an arbitrary template.
