POST 不写入数据库

Question

我在下面有我的 requestaccess 视图，如果我删除 if request.method == 'POST'，它将写入我的数据库，但如果我保留它。请求永远不会被写入。我试图了解为什么 POST 没有发生以及如何使它发生？

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 == 'POST' 语句永远不会返回正确的值，只会返回用于测试的硬编码值。

我的模板 requestaccess.html 可以在下面找到。当我更改选择选项以及单击按钮时，我可以看到 ajax 函数的 POST 请求正在更新。

下面是显示 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

单击提交按钮后，它会显示以下内容：

[2017 年 12 月 7 日 13:33:59]“POST /account/requestaccess/HTTP/1.1”200 3776 没有任何 无

编辑：

将 javascript 更改为 on('click' 而不是 on('change' 会产生相同的 None 值。

checkedlist = request.GET.getlist('report_id') 是罪魁祸首。您正在从 GET 请求中填充它，当您发布时，它们不会以任何方式转移。

因此，checkedlist 是 None，并且保存语句永远不会触发。
