找不到 'user_edit' 的反向。 'user_edit' 不是有效的视图函数或模式名称

Question

我已经坚持了一段时间，似乎无法修复错误。我已经检查了代码一百次，但显然我遗漏了一些东西。我也安装了我的应用程序。

我使用 3 个按钮为用户创建了 CRUD 操作：详细信息、编辑和删除 .第二个 2 完全按照它应该的方式工作，但是第一个 'Details' 给了我这个错误：

NoReverseMatch at /users/details/1 Reverse for 'user_edit' not found. 'user_edit' is not a valid view function or pattern name.

我正在尝试渲染 user_details 函数，但我找不到为什么 user_edit 错误信息。

有人能看到我遗漏了什么吗？

views.py

def user_details(request, id=None):
    context = {}
    context['user'] = get_object_or_404(User, id=id)
    return render(request, 'userdetails.html', context)

def user_add(request):
    context = {}
    if request.method == 'POST':
        u = user_form = UserForm(request.POST)
        context['user_form'] = user_form
        if user_form.is_valid():
            user_form.save()
            return HttpResponseRedirect(reverse('feedback:users'))
        else:
            return render(request, 'useradd.html', context)
    else:
        user_form = UserForm()
        context['user_form'] = user_form
        return render(request, 'useradd.html', context)

def user_edit(request, id=None):
    context = {}
    user = get_object_or_404(User, id=id)
    if request.method == 'POST':
        user_form = UserForm(request.POST, instance=user)
        context['user_form'] = user_form
        if user_form.is_valid():
            user_form.save()
            return HttpResponseRedirect(reverse('feedback:users'))
        else:
            return render(request, 'useredit.html', context)
    else:
        user_form = UserForm(instance=user)
        context['user_form'] = user_form
        return render(request, 'useredit.html', context)

def user_delete(request, id=None):
    context = {}
    return render(request, 'userdelete.html', context)

urls.py

from django.urls import path, include
from . import views

app_name = 'feedback'

urlpatterns = [
    path('login/', views.loginPage, name="login"),
    path('logout/', views.logoutUser, name="logout"),

    path('', views.index, name="index"),  
    
    path('patient/', views.patient, name="patient"),

    path('surveys/', views.surveys, name="surveys"),
    path('surveys/details/<int:id>', views.survey_details, name="surveydetails"),

    path('department/', views.department, name="department"),

    path('staff/', views.staff, name="staff"),

    path('imports/', views.imports, name="imports"),
    
    path('logs/', views.logs, name="logs"),
    
    path('users/', views.users, name="users"),
    path('users/add', views.user_add, name="useradd"),

    path('users/delete/<int:id>', views.user_delete, name="userdelete"),

    path('webflowroute/', views.webflowroute, name="webflowroute"),
    ]

users.html（基本上是我的 CRUD 导航索引页）

{% extends 'main.html' %}

{% block content%}

    <h1>Users</h1>
    <a href="/users/add">Add user</a>
    <h2>List of {{title}} </h2>
    {% if users %}
        <ul>
            {% for user in users %}
                <li>
                    {{user.first_name}} &nbsp; {{user.last_name}}
                    <td class="text-center">
                        <a class="btn btn-primary float-center" href="{% url 'feedback:userdetails' user.id %}">Details</a>
                        <a class="btn btn-warning float-center" href="{% url 'feedback:useredit' user.id %}">Edit</a>
                        <a class="btn btn-danger float-center" href="{% url 'feedback:userdelete' user.id %}">Delete</a>
                    </td>
                </li>
            {% endfor %}
        </ul>
        {% else %}
            <p>There is no users available</p>
        {% endif %}
{% endblock content %}

Answer 1

你能提供项目文件夹中的 urls.py 文件吗？？我认为问题出在项目文件夹中的 urls.py 文件，您应该提供“appname”和“namescape”

Answer 2

在 urls.py 文件中，在行

path('users/edit/<int:id>', views.user_edit, name="useredit"),

将name="useredit"更改为name="user_edit"
