benutzerdefinierte Filter auf Kontakt nach Datum - Django Rest Framework

Question

Ich habe eine Tabelle, in der ich Informationen über Organisationen anzeigen und ich habe einen Mechanismus, der nächste Aktion Datum auf der Organisation auslöst, die manuell auf den Organisationen festgelegt ist. Jetzt habe ich ein benutzerdefiniertes Feld datepicker oben auf meiner Tabelle hinzugefügt, so dass ich es für das gewünschte Datum filtern und alle next action date für diese Organisation am ausgewählten Datum anzeigen kann, so übergebe ich einen Wert an Controller, damit ich in der restAPI, und in der rest möchte ich Filter das Datum zu sein vor oder gleich jetzt, so dass ich Organisationen bis zum nächsten Aktion Datum zeigen kann. Meine Frage ist, wie man das Datum filtert, um vor oder gleich jetzt zu sein, verlor ich wirklich hier, also kann mir jemand helfen und erklären, wie ich das in meinem ModelViewSet tun kann.

ModelViewSet:

from rest_framework import viewsets, permissions, filters 

from cms.restapi.pagination import StandardResultsOffsetPagination 
from cms_sales.models import LeadContact 
from cms_sales.restapi.permissions.lead_contact_permissions import LeadContactPermissions 
from cms_sales.restapi.serializers.lead_contact_serializer import LeadContactSerializer 


class LeadContactViewSet(viewsets.ModelViewSet): 
    def get_queryset(self): 
     queryset = LeadContact.objects.none() 
     user = self.request.user 
     if user.has_perm('vinclucms_sales.can_view_full_lead_contact_list'): 
      queryset = LeadContact.objects.all() 
     elif user.has_perm('vinclucms_sales.can_view_lead_contact'): 
      queryset = LeadContact.objects.filter(account_handler=user) 
     return queryset 

    serializer_class = LeadContactSerializer 

    filter_backends = (filters.DjangoFilterBackend, filters.SearchFilter, filters.OrderingFilter) 

    filter_fields = ('account_handler',) 

    ordering_fields = (
     'first_name', 'last_name', 'account_handler__first_name', 'account_handler__last_name', 
     'sub_organization_name', 'organization_name', 'next_action_date', 'serial_number', 
     'next_action_date', 'status_text', 'select_date') 

    search_fields = (
     'first_name', 'last_name', 'account_handler__first_name', 'account_handler__last_name', 
     'sub_organization_name', 'organization_name', 'next_action_date', 'serial_number', 
     'next_action_date', 'status_text', 'select_date') 

    pagination_class = StandardResultsOffsetPagination 

    permission_classes = [permissions.IsAuthenticated, LeadContactPermissions] 

Cotroller, wo ich das datepicker Feld passieren:

app = angular.module 'cms.sales' 

app.controller 'LeadContactListCtrl', ['$scope', '$rootScope', '$compile', 'LeadContacts' 
    ($scope, $rootScope, $compile, LeadContacts) ->

Ich bin mir nicht sicher, ob ich voll habe verstanden, was Sie Fragen, aber ein QuerySet zu filtern, um nur Objekte mit einem next_action_date in der Zukunft anzuzeigen e können Sie verwenden:

import datetime 
LeadContact.objects.filter(next_action_date__gte=datetime.date.today()) 

und nur diejenigen mit Terminen in der Vergangenheit Verwendung anzuzeigen:

LeadContact.objects.filter(next_action_date__lte=datetime.date.today()) 

this answer für eine detaillierte Anleitung finden Sie QuerySets nach Datum filtern. Wenn der Typ Ihres next_action_date-Felds Datetime ist, verwenden Sie datetime.datetime.now() lieber als datetime.date.today(). Mehr Informationen auch in der QuerySet docs.
