Use this decorator on a function that returns a dict to get a JSON view, with error handling. Features: * response always includes a 'result' attribute ('ok' by default) * catches all errors and mails the admins * always returns JSON even on errors
Two common generic views to be used with newforms in similar way django.views.generic.create_update views, but adapted to the newforms library.
Decorator to make a view only accept requests from AJAX calls. Usage:: @require_xhr() def my_view(request): # Returns data # ... by [skam](http://skam.webfactional.com/)
This will return HTTP 405 if request was not POSTed. same way you can forbide POST request, change 'POST' to 'GET' Decorators provided for your convenience.
Peeping middleware, that replaces active user to another one for current http request. Admin permissions required to activate, so you can place this snippet even on the production server. Very useful for debugging purposes. Wish it to be part of Django. How to use: Put this middleware after all other middlewares in the list. Then just add ?as_user=username or &as_user=username to the url, where username is the name of user whose views you want to see.
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
Decorator adding arbitrary HTTP headers to the response. This decorator adds HTTP headers specified in the argument (map), to the HTTPResponse returned by the function being decorated. Example: @headers({'Refresh': '10', 'X-Bender': 'Bite my shiny, metal ass!'}) def index(request): ....
This a small but very handy view that gives you a convenient direct access to your templates. Now suppose you saved the snippet under `misc.py`, it's critical to add this snippet (or a similar one, once you get the idea) to your `urls.py`: if settings.DEBUG: # Direct Templates urlpatterns += patterns('misc', (r'^template/(?P<path>.*)$', 'direct_to_template', {'template': '%(path)s'}), ) Now you are able to access any of your templates, in different directories by specifying their path after `template/`. e.g., http://example.com/template/news/index.html Of course you can change it as you want, you can also add other values to the dict argument, the only required key is `'template'`. The whole dict is made available in the template as a context. All GET parameters are made available in the template too. So `http://example.com/template/news/index.html?title=Testing Title` will make the `{{ title }}` var available in your template. So you can substitute basic variables quickly. This is was inspired by [django.views.generic.simple.direct_to_template](http://www.djangoproject.com/documentation/generic_views/#django-views-generic-simple-direct-to-template)
Here are a couple of Django decorators for limiting access to a view based on the request's `HTTP_REFERER`. Both raise a Django `PermissionDenied` exception if the referer test fails (or a referer simply isn't provided). The first, `referer_matches_hostname`, takes a hostname (and port, if specified) and matches it against the referer's. If multiple arguments are supplied a match against any of the hostnames will be considered valid. The second, `referer_matches_re`, takes a regex pattern (like Django's urlpattern) and tests if it matches the referer. This is obviously more flexible than `referer_matches_hostname` providing the ability to match not just the hostname, but any part of the referer url. Finally there's an simple example decorator, `local_referer_only`, that limits a view to the current site by using Django's `django.contrib.sites` to look up the current hostname.
