This is another foreign key to User model. User is automatically associated before save. Requires: [ThreadlocalsMiddleware](http://code.djangoproject.com/wiki/CookBookThreadlocalsAndUser) Inspired by: [snippet 509](http://www.djangosnippets.org/snippets/509/)
Tuned IPAddressField with IPv4 & IPv6 support
FieldStack simplifies forms template rendering. This is enhanced version of snippet [1786](http://djangosnippets.org/snippets/1786/)
This snippet was inspired by [1783](http://www.djangosnippets.org/snippets/1783/). It allows simply create groups of fields for template rendering.
This templatetag evaluates Python expressions including built-in functions, lambda functions etc... Use with caution.
Standard memcache client uses pickle as a serialization format. It can be handy to use json, especially when another component (e.g. backend) doesn't know pickle, but json yes.
If you have a model with foreign key to User, you can use this manager to show (i.e. in admin interface) only objects, that are related to currently logged-in user. Superuser sees all objects, not only his. Requires: [ThreadlocalsMiddleware](http://code.djangoproject.com/wiki/CookBookThreadlocalsAndUser)
Supported MAC formats: aa:bb:cc:dd:ee:ff, separator : or - aabbccddeeff both lower case and upper case
Rename apache (or any) processes to be easily identified from ps output.
Use this, if you want to "activate" menu items by URL. Typical usage is with CSS class 'active'.
This code adds new field to Django user model. It must be executed early as much as possible, so put this code to __init__.py of some application.
This is a XML-RPC server, that uses arguments in URLs and every dispatcher instance is prepared in memory during webserver run. It's good, for example, for securing XML-RPC server with hashed strings and there are a lot of similar use cases. Usage: from xmlrpclib import ServerProxy server = ServerProxy('http://example.com/xmlr-rpc/%s/' % something, allow_none=True) server.do_something(*args)
When you neeed to do redirect and request object is not available, you can do it with exception. Put exception handler somewhere request is available, for example to middleware or ModelAdmin. Raise exception, where request is not available.
Other approach of making middleware. Advantage of is to specify, which middleware is used for which view function and in what order. Middleware function gets all arguments, that are passed to view function. **Example usage** @RequestMiddleware def print_params_middleware(request, *args, **kwargs): print 'GET params:', request.GET @ResponseMiddleware def modify_headers_middleware(request, response, *args, **kwargs): response['Content-Type'] = 'text/html' @ExceptionMiddleware def catch_error_middleware(request, e, *args, **kwargs): return HttpResponse('catched error %s' % e ) @modify_headers_middleware @catch_error_middleware @print_params_middleware def some_view(request, *args, **kwargs): print 'someview' return HttpResponse()
Consider following models: class Product(models.Model): code = modeld.CharField() class ProductTrans(models.Model): product = models.ForeignKey('Product') language = models.ChoiceField(choices=settings.LANGUAGES) title = models.ChaField() description = models.ChaField() With this snippet is possible search through all translations of product at the same time (using string concatenation in trigger): Product.objects.extra( where = ['product_product.fulltext @@ to_tsquery(%s)'], params = [ 'someproduct' ] ) For PostgreSQL >=8.4 only.
