我有一个表格，其中显示有关组织的信息，我有一个机制，它在组织上触发下一个操作日期，这是在组织上手动设置的。
现在，我已在桌面上添加了自定义datepicker字段，因此我可以根据所需日期对其进行过滤，并在所选日期显示该组织的所有next action date，因此我可以将值传递给Controller，以便我可以抓住restAPI，而rest我希望过滤日期等于或等于现在所以我可以通过下一个行动日期向组织展示。
我的问题是如何过滤日期之前或等于现在，我真的迷失在这里，所以有人可以帮助我并解释我如何在我的ModelViewSet中做到这一点。
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]
我通过datepicker字段的Cotroller：
app = angular.module 'cms.sales'
app.controller 'LeadContactListCtrl', ['$scope', '$rootScope', '$compile', 'LeadContacts'
($scope, $rootScope, $compile, LeadContacts) ->
savedSuccessMessage = "Lead Contact List was updated"
savedFailMessage = "Failed to update lead contact list"
$scope.init = ()->
fetchLeadContacts()
fetchLeadContacts = () ->
$('#expensesListTable').DataTable(
createdRow: (row, data, index) ->
$compile(row)($scope)
sDom: 'lfrtip'
processing: true
serverSide: true
searchDelay: 1000
orderMulti: false
pageLength: 25
ajax:
url: '/api/sales/lead_contact/'
data: (data) ->
data.limit = data.length
data.offset = data.start
data.search = data.search['value']
if data.order[0]['dir'] == 'asc'
data.ordering = data.columns[data.order[0]['column']].name
else
data.ordering = '-' + data.columns[data.order[0]['column']].name
return 0
dataFilter: (data) ->
json = jQuery.parseJSON(data)
json.recordsTotal = json.count
json.recordsFiltered = json.count
json.data = json.results
return JSON.stringify json
columns: [

}

render: (data, type, row, meta)->
return row['first_name'] + ' ' + row['last_name']

}
{

render: (data, type, row, meta)->
return "<span class='" + row['status_display_class'] + "'>" + data + "</span>"
}
{

render: (data, type, row, meta)->
initValue = data
if data
initValue = "'" + data + "'"
return '<div class="input-control text" data-role="datepicker"

}
])
$scope.SelectLeadContacts = () ->
params = {}
if $scope.lead_contact.id
params['id'] = $scope.lead_contact.id
LeadContacts.update(params).$promise.then saveSuccessCallback, saveFailedCallback
else
LeadContacts.save(params).$promise.then saveSuccessCallback, saveFailedCallback
saveSuccessCallback = (response) ->
ClientNotifications.showNotification("Success", savedSuccessMessage, "success")
saveFailedCallback = (error) ->
ClientNotifications.showNotification("Alert", savedFailMessage, "alert")
$scope.showAddNew = ()->
initNewLeadContacts()
initNewLeadContacts = ()->
$scope.lead_contact = {}
$scope.lead_contact.select_date = 'Jan 1, 2200'
]

我不确定我是否已完全理解您的要求，但过滤QuerySet以便将来只显示next_action_date的对象，您可以使用：
import datetime
LeadContact.objects.filter(next_action_date__gte=datetime.date.today())
并仅显示过去使用日期的那些：
LeadContact.objects.filter(next_action_date__lte=datetime.date.today())
有关按日期过滤QuerySet的更详细指南，请参阅this answer。特别是，如果next_action_date字段的类型是日期时间，请使用datetime.datetime.now()而不是datetime.date.today()。更多信息也在QuerySet docs。
