python - django 如何使用 UserChangeForm 更改帐户信息

Question

我正在使用 django 制作一个网站。我正在 YouTube 上学习“如何让 super 用户使用表单更改帐户信息”。但是，我在编辑页面时遇到问题。

管理应用中的member_management.html

      {% for staff in staff_list %}
        <tr>
            <td><a href="{% url "management:edit_staff" staff.id %}">{{ staff }}</a></td>
            <td>{{ staff.birth }}</td>
            <td>{{ staff.groups.all.0 }}</td>
        </tr>
        {% endfor %}

如果我点击 {{staff}}，页面 URL 会将“management/member_management”更改为“management/member_management/edit_staff/1”( 1 是员工 ID )。但页面不会转到edit_staff页面，而是重定向memeber_management页面(此页面)。

管理应用程序中的我的 urls.py

  from django.conf.urls import url, include
  from management import views

   urlpatterns = [
url(r'^member_management/', views.member_management, name='member_management'),
url(r'^member_management/edit_staff/(?P<staff_id>\d+)', views.edit_staff, name="edit_staff"),  
 ]

管理应用程序中的我的views.py

from django.conf import settings
from django.shortcuts import render, redirect
from django.contrib.auth.forms import UserChangeForm
from authentication.models import User
from staff.models import Member

def member_management(request):
    staff_list = User.objects.all()
    member_list = Member.objects.all()
    context = {
        'staff_list':staff_list,
        'member_list' : member_list,
    }
    return render(request, 'management/member_management.html', context)

def edit_staff(request, staff_id):
    staff = User.objects.get(id=staff_id)
    print("sdf")

    if request.method == 'POST':
        form = UserChangeForm(request.POST, instance=staff)

        if form.is_valid():
            form.save()
            return redirect('member_management')
    else:
        staff = User.objects.get(id=staff_id)
        form = UserChangeForm(instance=staff)

    context = {
        'form' : form,
    }
    return render(request, 'management/edit_staff.html', context)

有什么问题吗？我的 CMD 中没有出现任何错误，也许我错过了一些路线..任何帮助都会对我非常有帮助，谢谢!

您可以解决此问题，只需将 $(字符串结尾匹配字符) 放在第一个网址的末尾即可。

urlpatterns = [
    url(r'^member_management/$', views.member_management, 
      name='member_management'),
    url(r'^member_management/edit_staff/(?P<staff_id>\d+)', 
      views.edit_staff, name="edit_staff"),  
]

Note that the regular expressions in this example don’t have a $ (end-of-string match character) but do include a trailing slash. Whenever Django encounters include() (django.conf.urls.include()), it chops off whatever part of the URL matched up to that point and sends the remaining string to the included URLconf for further processing.

如果您不输入 $，您可能会遇到意想不到的结果，例如:

management/member_management/edit_staff/1/foo/bar/baz 将匹配，并将调用 views.edit_staff

为避免这种情况，您还应该在 edit_staff 网址中包含 $。

url(r'^member_management/edit_staff/(?P<staff_id>\d+)$', 
      views.edit_staff, name="edit_staff"),
