Django getlist() 错误？

Question

我没有收到任何错误，但我知道数据库中的保存记录不正确，是 getlist() 中的错误吗？ 还是我错过了代码中的某些内容？ 请告诉我为什么错误的记录保存在数据库中

def corevalues(request):
    coregradelevel = request.GET.get('coregradelevel')
    coreperiod = request.GET.get('coreperiod')
    marking = StudentBehaviorMarking.objects.all()
    teacher = request.GET.get('teacher')
    corevalues = CoreValues.objects.all().order_by('Display_Sequence')
    corevaluesdescription = CoreValuesDescription.objects.values('id','Description').distinct('Description').order_by('Description')
    corevaluesperiod = CoreValuesDescription.objects.filter(grading_Period=coreperiod).order_by('Display_Sequence')
    period = gradingPeriod.objects.filter(id=coreperiod).order_by('Display_Sequence')
    gradelevel = EducationLevel.objects.filter(id__in = coregradelevel).distinct().order_by('id')

    studentcorevalues = StudentsCoreValuesDescription.objects.filter(Teacher = teacher).filter(GradeLevel = gradelevel.values_list('Description'))\
        .values('Students_Enrollment_Records').distinct('Students_Enrollment_Records').order_by('Students_Enrollment_Records')

    student = StudentPeriodSummary.objects.filter(Teacher = teacher).filter(GradeLevel__in = gradelevel.values_list('id'))

这是我的 html 代码

<table class="tblcore">
        <tr>
            <td rowspan="2" colspan="2">Core Values</td>
            {% for core in corevalues %}

            {% endfor %}

        <tr>

                <td colspan="4" style="font-size: 12px"><input type="hidden" value="{{corevalues.id}}" name="coredescription">{{corevalues.Description}}</td>

            </td>
        </tr>
        {% endfor %}
    </table>

这是它的样子

这是我插入数据的代码

global marking,coreperiod,corevalues
id = request.POST.get('teacher')
teacher = EmployeeUser(id=id)

coreid = request.POST.get('core')
core = CoreValues(id=coreid)


corevalues = []
for corevaluesid in request.POST.getlist('coredescription'):
    corevalues.append(corevaluesid)



coreperiodID = request.POST.get('coreperiod')
coreperiod = gradingPeriod(id = coreperiodID)


marking = []
for markingID in request.POST.getlist('marking'):
    marking.append(markingID)
    print(markingID)


for desc,m in enumerate(request.POST.getlist('marking')):
    coredesc = corevalues[desc]
    print(corevalues[desc])
    coredescription = CoreValuesDescription(id=coredesc)
    print("behavior",m)
    for student in request.POST.getlist('student'):
        students = StudentPeriodSummary(id=student)
        V_insert_data = StudentsCoreValuesDescription(
            Core_Values=coredescription,
            Marking=m,
            Students_Enrollment_Records=students,
            grading_Period = coreperiod,
        )
        V_insert_data.save()

我没有收到任何错误，但是

您的某些选择选项没有名称，这就是它没有获取所有数据的原因：

    <input type="submit" value="Update">

并对我的观点这样做

   for desc, m in enumerate(request.POST.getlist('marking')):
        coredesc = corevalues[desc]
        coredescription = CoreValuesDescription(id=coredesc)

    for student in request.POST.getlist('student'):
        students = StudentPeriodSummary(id=student)
        V_insert_data = StudentsCoreValuesDescription(
            #Teacher=teacher,
            Core_Values=coredescription,
            Marking=m,
            Students_Enrollment_Records=students,
            grading_Period = coreperiod,
        )
        V_insert_data.save()
