Question

我有下面的requestaccess视图，如果我删除了if request.method ==＆＃39; POST＆＃39;，如果我保留它，将写入我的数据库。请求永远不会被写入。我试图理解为什么POST没有发生以及如何实现它？

def requestaccess(request):

    owner = User.objects.get (formattedusername=request.user.formattedusername)

    reportdetail = QVReportAccess.objects.filter(ntname = owner.formattedusername, active = 1).values('report_name_sc')
    reportIds = QVReportAccess.objects.filter(ntname = owner.formattedusername).values_list('report_id', flat=True)
    checkedlist = request.GET.getlist('report_id')
    reportlist = QvReportList.objects.filter(report_id__in= checkedlist, active = 1).values_list('report_name_sc',flat = True)


    coid = User.objects.filter(coid = request.user.coid).filter(formattedusername=request.user.formattedusername)
    facilitycfo =  QvDatareducecfo.objects.filter(dr_code__exact = coid , active = 1, cfo_type = 1).values_list('cfo_ntname', flat = True)
    divisioncfo =  QvDatareducecfo.objects.filter(dr_code__exact = coid, active = 1, cfo_type = 2).values_list('cfo_ntname', flat = True)
    selectedaccesslevel = '7'
    if request.method == 'POST':
        selectedaccesslevel = request.POST.get('accesslevelid')
        print(selectedaccesslevel)
    selectedphi = '0'
    if request.method == 'POST':
        selectedphi = request.POST.get('phi')
        print(selectedphi)
    if request.method == 'POST':
        for i in checkedlist:
            requestsave = QVFormAccessRequest(ntname = owner.formattedusername, first_name = owner.first_name, last_name = owner.last_name, coid = owner.coid, facility = owner.facility, title = owner.title
                                      ,report_id = i, accesslevel_id = selectedaccesslevel, phi = selectedphi, access_beg_date = '2017-01-01 00:00:00', access_end_date = '2017-01-31 00:00:00')
            requestsave.save()

    args = {'retreivecheckbox': reportlist, 'cfo7':facilitycfo, 'cfo5':divisioncfo, 'checkedlist':checkedlist }

    return render(request,'accounts/requestaccess.html', args)
#    return render(request, 'accounts/requestaccess.html', args)

我的request.method ==＆＃39; POST＆＃39;语句永远不会返回正确的值，仅用于测试的硬编码值。

我的模板requestaccess.html可以在下面找到。当我更改选择选项并单击按钮时，我可以看到更新ajax函数的POST请求。

以下是显示POST的控制台：

[07/Dec/2017 13:21:14] "GET /account/requestaccess/?report_id=84&report_id=87&report_id=88 HTTP/1.
3

[07/Dec/2017 13:21:22] "POST /account/requestaccess/ HTTP/1.1" 200 3928
3
1

点击提交按钮后，它给出了以下内容：

[07 / Dec / 2017 13:33:59]＆＃34; POST / account / requestaccess / HTTP / 1.1＆＃34; 200 3776 没有无

编辑：

将javascript更改为开启（＆＃39;点击＆＃39;而不是on（＆＃39;更改＆＃39;生成相同的无值。

Answer 1

checkedlist = request.GET.getlist('report_id')是罪魁祸首。您正在从GET请求填充该内容，当您发布POST时，这些内容不会以任何方式结转。

因此，checkedlist为None，并且保存语句永远不会触发。

POST不会写入数据库
