How to put an InlineFormSet into a ModelFormSet in Django? -

-

I ModelFormSet many forms through would display where all associated with each form object InlineFormSets displays in exchange for objects

Now I'm not really sure how to provide examples for each ModelFormSet . I BaseModelFormSet thought about subclassing, but I at all where to start and knowing that it is possible before that I have no clue on how to go through all the trouble.

Thanks in advance!

I have found an article that is focused on the exact problem. It works fine

For the sake of completeness I copied the code piece: 

  class blocks (models.Model): Description = model .CharField (MAX_LENGTH = 255) square building (models.Model): block = models.ForeignKey (block) address = models.CharField (MAX_LENGTH = 255) class tenant (models.Model): building = models.ForeignKey ( Building) name = models.CharField (MAX_LENGTH = 255) unit = models.CharField (MAX_LENGTH = 255) form the django.forms.models inlineformset_factory import, BaseInlineFormSet TenantFormset = inlineformset_factory (models.Building, models.Tenant, additional = 1) Class BaseBuildingFormset (BaseInlineFormSet): Def add_fields ( Self, form, index) :) Example = self.get_queryset ([: # Super-class fields as usual (BaseBuildingFormset, self) .add_fields (form, index) #Nested formset made to try to create index index] pk_value = instance.pk excluding index example = no pk_value = hash (form.prefix) # store .nested property formset form.nested = [TenantFormset (data = Selfkdata, for example = example, prefix = ' TENANTS_% s'% pk_value)] BuildingFormset = Inlineformset_factory (models.Block, models.Building, formset = BaseBuildingFormset, additional = 1)

-
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?

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.
