url.py

from django.urls import path
from . import views

urlpatterns = [
    path('certificationEdit/<int:pk>', views.certificationEdit, name='certificationEdit'),
]

views.py

@login_required(login_url='login')
def certificationEdit(request, pk):
    certification = get_object_or_404(empCertification, id=pk)
    certificaitonForm = empCertificationForm(instance=certification)
    if request.method == 'POST':
        certificaitonForm = empCertificationForm(request.POST, instance=certification)
        if certificaitonForm.is_valid():
            certificaitonForm.save()
            messages.success(request, 'Certification has been updated.')
            return redirect('certificationList')
        else:
            messages.error(request, 'Please correct form errors.')

    context = {
        'certification': certification,
        'certificaitonForm': certificaitonForm,
    }
    return render(request, 'back/pages/certification/update.html', context)

显示/隐藏表单字段我使用以下JavaScript函数在添加数据时显示和隐藏字段。

$('select[name="certValidity"]').on('change', function(){
        if ($(this).val() == 'One Time') {
            $('.certEndDate').hide();
        } else {
            $('.certEndDate').show();
        }
    });

但是当使用Django模板检索同一行时，它会显示所有字段。

**例如：**如果我将证书有效期保存为“一次性”，其中不包括“CertEndDate”，并且当我尝试检索相同的数据时，其显示“certEndDate”字段。

所以我的问题是如何在检索“一次性”证书数据时隐藏certEndDate。
