Django: Filtering or displaying a model method in Django Admin -

-

I have a model with a timeout DateField.

I want to install an administrator filter that will allow the user to toggle between "no expiration" and "any".

Model method is quite simple date comparison, no problem.

However this parameter or filter is not automatic in the admin farm.

Is such a thing possible, and if not, what would be an intelligent task ...

I would also be open to something like automatic extinction of deadlines , But I do not know how to start that path down.

After

You can enter two ModelAdmin sections for this two times on the admin site Models can be included. You can override the query-based () method to ModelAdmin to customize the code that has been shown. Note that you need to define a model proxy and use that in the second ModelAdmin class, otherwise Django complains about registration twice the same model.

models.py 

  class ExampleModel (models.Model): has expired = models.DateField () Class ExpiredExampleModelProxy (ExampleModel): Square Meta: Proxy = True Verbose_name = 'expired example' verbose_name_plural = 'expired example'

admin.py 

  class NotExpiredExampleAdmin (models.ModelAdmin): def Queryset (self, requested): return (super (ExampleAdmin, self) .queryset (request) .filter (expiration__gte = date.today ()) class ExpiredExampleAdmin (models.ModelAdmin): def querygroup (self, requested): Return ( Super (ExampleAdmin, Self) .queryset (request) .filter (expiration__lt = date.toda ()) Admin.site.register (exampleModel, NotExpiredExampleAdmin) admin.site.register (timedoutEditModelProxix, ExpiredImport

ModelAdmin.queryset Instead you can define the module's custom manager to get the same filtering out of the administrator too.

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...
