模型.py

class Report(models.Model):
    user = models.ForeignKey(User, null=False)
    incident_number = models.CharField('Incident Number', max_length=100)
    device_id = models.CharField('Device Id', max_length=100)
    app_uuid = models.CharField('Unique App Id', max_length=100)
    created_date_time = models.DateTimeField('Created',auto_now=True)
    manual_date = models.DateField('manual date', null=True, blank=True)
    manual_time = models.TimeField('manual time',null=True, blank=True)

上面的代码用于执行编辑操作。我遇到了很多错误，例如："when() got an unexpected keyword argument 'id'"

when函数应该有名为idnot的参数pk。

所以改变

def when(request,pk=id):

至

def when(request,id):

Report此外，当给定的 id 不存在时，您需要适当地处理大小写。

编辑：

您还需要传递id给模板，以便表单 url 是合适的。此外，针对其他问题更新您的视图，如下所示。

def when(request,id):
    try:
        report = Report.objects.get(pk=id)
    except ObjectDoesNotExists:
        #handle when report does not exists

    if request.method == 'POST':

        reportform = ReportForm(data=request.POST, instance=report)

        if reportform.is_valid():
            log.debug("test:%s",reportform)

            report = reportform.save(commit=False)
            report.user = request.user
            report.save()
            return redirect('/member/media/')
    else:
        reportform = ReportForm(instance=report)
    return render_to_response('incident/when.html',{
                  'newreport_menu': True, 
                  'form': reportform,
                  'report_id': id,        #pass id too
                   },
                   context_instance=RequestContext(request))

模板：

<form action="/member/when/{{report_id}}" method="POST"> {% csrf_token %}
