Question

我正在尝试执行“添加成员”功能。基本上，当您单击“添加按钮”按钮时，成员名称将显示在此页面的某个位置。但是我收到此错误：

这里是HTML的一部分，看起来像：

project_detail.html

stdout

urls.py

{% extends 'base.html' %}

{% block content %}
  <p>Project {{ project_id }} detail</p>
    <div class="btn btn-default oval" style="width: 10%"><a href="{% url 'project:project_edit' project_id=project_id%}">Edit</a></div>
    <div class="btn btn-default oval"style="width: 10%"><a href="{% url 'project:project_delete' project_id=project_id%}">Delete</a></div>
    <div class="btn btn-default oval"style="width: 10%">Members</div>
     <form action="" method="POST" id="selection-form">
                  {% csrf_token %}
                    <select id="member_list">
                            {% for user in users %}
                        <option value="{{user.id}}">
                            {{ user.username }}
                        </option>
                   {% endfor %}
                    </select>

                     <input type="button" value="Add member" id="selection-button">
                     </form>

                    <div id="res"> </div>


{% endblock %}


{% block script %}
    var url = $( '#selection-button' ).attr( 'action' );
    $("#selection-button").on('click', function(e) {
        e.preventDefault();
        var value =$('#member_list').val();
        $.ajax({
            type:'POST',
            url:'add_member/'+value+'/',
            success:function (result) {
                $("#res").append(value);
            },
            error:function (result) {
              alert('error');
            }
        });
    });

{%  endblock %}

views.py

urlpatterns = [
    path('', views.project_index, name='project_index'),
    path('<int:project_id>/', views.project_detail, name='project_detail'),
    path('create/', views.project_create, name='project_create'),
    path('<int:project_id>/delete/', views.project_delete, name='project_delete'),
    path('<int:project_id>/delete_result/', TemplateView.as_view(template_name="project/delete_result.html"), name='delete_result'),
    path('<int:project_id>/edit/', views.project_edit, name='project_edit'),
    path('<int:project_id>/add_member/<int:user_id>', views.add_member, name='project_add_member'),

    path('<int:project_id>/task/', include('task_tracker.urls')),
    path('<int:project_id>/issue/', include('issue_tracker.urls',namespace='issue_tracker')),
    path('<int:project_id>/channel/', include('communication_channel.urls')),
]

project_add_member.html

def add_member(request,project_id):
    if request.method=='POST':
        members = User.objects.all()
        serializer = UserSerializer()
        return render(request,'project/project_add_member',{'project_id':project_id})

views.py

{% extends 'base.html' %}
{% block content %}
<div>success!</div>
{% endblock %}

我不知道哪里错了。好像是URL？让我知道是否需要我上传更多代码来确定问题。

您的视图add_member应该声明它收到的两个URL参数：

更改

def add_member(request,project_id):
    ...

到

def add_member(request, project_id, user_id):
    project = get_object_or_404(Project, id=project_id)
    user = get_object_or_404(User, id=user_id)
    ...

找不到页面404
