在提交此表单期间，url 中的表单操作可能存在一些问题我的意思是当我单击此更新按钮时，我收到页面未找到错误 404

这是我的意见.py

def delete(request, id):
    i = ApplyForm.objects.get(id = id)
    i.delete()
    return redirect('account:dboard')


def edit(request, id):
    i = ApplyForm.objects.get(id = id)
    context = {
        'i' : i
    }
    return render(request, 'account/edit.html', context)

def update(request, id):
    i = ApplyForm.objects.get(id = id)
    i.full_name = request.POST['full_name']
    i.email = request.POST['email']
    i.noticeperiod = request.POST['noticeperiod']
    i.preferredlocation = request.POST['preferredlocation']
    i.expectedlocation = request.POST['expectedlocation']
    i.currentctc = request.POST['currentctc']
    i.expectedctc= request.POST['expectedctc']
    i.recruiter_name = request.POST['recruiter_name']
    i.status = request.POST['status']
    i.gender = request.POST['gender']
    i.cv = request.POST['cv']
    i.save()
    return redirect('account:dboard')

和 urls.py

urlpatterns = [

    path('employee/register/', views.employee_registration, name='employee-registration'),
    path('employer/register/', views.employer_registration, name='employer-registration'),
    path('applyform/', views.applyform, name='applyform'),
    path('dboard/', views.dboard, name='dboard'),
    path('export_excel/', views.export_excel),
    path('delete/<id>/', views.delete, name='delete'),
    path('edit/<id>/', views.edit, name='edit'),
    path('update/<id>/', views.update, name='update'),
    path('profile/edit/<int:id>/', views.employee_edit_profile, name='edit-profile'),
    path('login/', views.user_logIn, name='login'),
    path('logout/', views.user_logOut, name='logout'),
]

这是models.py

class ApplyForm(models.Model):
    full_name = models.CharField(max_length=300)
    email = models.EmailField(max_length=300)
    noticeperiod = models.CharField(max_length = 300)
    preferredlocation = models.CharField(max_length=300)
    expectedlocation = models.CharField(max_length=300)
    currentctc = models.CharField(max_length=300)
    expectedctc = models.CharField(max_length=300)
    recruiter_name = models.CharField(max_length = 300, null=True)
    status = models.CharField(max_length = 300,  null=True, choices= CATEGORY_CHOICES )
    gender = models.CharField(max_length=10, choices=GENDER_CHOICES)
    cv = models.FileField(upload_to='')    
     

发生了什么我不知道当我单击更新按钮以更新我在edit.html 中的表单时，它显示找不到页面（404）请求方法发布。我只是想让更新按钮工作我认为表单操作有问题=/更新

显然有两个可能的问题可能导致这种情况：

您的表单 URL 没有 ID，因此您的表单如下所示<form ...="/update/">

settings.py中有一个设置APPEND_SLASH——可能是假的。所以你的网址看起来像 this/update/ID而不是 this /update/ID/。

检查它是否有 ID：打开站点并右键单击，选择显示源并检查表单元素以验证它确实有一个 ID。

设置APPEND_SLASH为 true 或将尾部斜杠添加到表单项：action="/update/{{i.id}}/"
