使用 Django DeleteView 使用两个参数进行删除 [重复]

Question

我正在尝试从特定客户端删除报告，因此目前在我的url.py 中，我正在传递客户端 ID 和报告 ID，希望从客户端 X 中删除报告 Y。我可以使用 @987654323 完成此操作@ ，但希望使用基于类的 DeleteView。

我查看了this example，但无法与我的代码融合。

这是我的代码。

urls.py

url(r'^jsclient/(?P<pk>\d+)/report/(?P<r_pk>\d+)/delete/$', ReportScheduleDeleteView.as_view(), name="report-delete"),

models.py -

class JSClient(models.Model):
    name = models.CharField(max_length=255, unique=True)
    clientAccount = models.CharField(max_length=255)
    ....

class ReportSchedule(models.Model):
    client = models.ForeignKey(JSClient)
    schedRepName = models.CharField(max_length=255)
    reportType = models.CharField(max_length=255, choices=REPORT_TYPE)
    ....

views.py：

class ReportScheduleDeleteView(DeleteView):   
    model = ReportSchedule
    template_name = "report/report_confirm_delete.html"
    success_url = lazy(reverse, str)('jsclient-list')

我确信必须有一种方法可以使用基于类的 DeleteView 来执行此操作，感谢您对此提供任何帮助。

感谢EsseTi 和CCBV site 的提示，我设法解决了我的问题。这可能是显而易见的

class ReportScheduleDeleteView(DeleteView):
    model = ReportSchedule
    template_name = "report/report_confirm_delete.html"
    success_url = lazy(reverse, str)('jsclient-list')

    # Get the parameters passed in the url so they can be used in the 
    # "report/report_confirm_delete.html"     


**UPDATE:**

    def get_object(self, queryset=None):
        if queryset is None:
            queryset = self.get_queryset()

        client = self.kwargs['pk']
        report = self.kwargs['rpk']

        queryset = ReportSchedule.objects.filter(client_id=client, id=report)

        if not queryset:
            raise Http404

        context = {'client_id':client, 'report_id':report}
        return context

    # Override the delete function to delete report Y from client X
    # Finally redirect back to the client X page with the list of reports
    def delete(self, request, *args, **kwargs):
        client = self.kwargs['pk']
        report = self.kwargs['rpk']

        clientReport = ReportSchedule.objects.filter(client_id=client, id=report)
        clientReport.delete()

        return HttpResponseRedirect(reverse('report-list', kwargs={'pk': client}))

希望对某人有所帮助。

和这个Example of Django Class-Based DeleteView类似

重新定义def get_object(self, queryset=None) 并在内部进行检查。 使用 kwargs 你应该能够从 url 获取参数。
