Python class-based-view updateview не сохраняется

Привет ребята, я новичок в программировании, я пытаюсь сделать сайт для Todo, используя Python-django. Я использую Django Class Based Update View для внесения изменений в данные. Но когда я нажимаю на кнопку submit, она не сохраняется

views.py

class TaskUpdateView(UpdateView):
model = Task
fields = "__all__"
template_name = 'update.html'
context_object_name = 'task'
success_url = reverse_lazy('cbvhome')

urls.py

path('update/<pk>',views.TaskUpdateView.as_view(),name='cbvupdate')

update.html

<form method="post" class=" justify-content-center align-items-center mb-4 ps" enctype="multipart/form-data">
                    {% csrf_token %}
                    <div class="mb-3">
                      <label for="task-id" class="form-label  me-5">Task</label>
                      <input type="text" name="name" class="form-control" id="task-id" aria-describedby="emailHelp" style="width: 80%;" placeholder="Enter your Task Here" value="{{task.name}}">
                    </div>
                    <div class="mb-3">
                        <label for="exampleFormControlTextarea1" class="form-label me-5">Enter the details</label>
                        <textarea class="form-control" name="details" id="task-detail"rows="2" placeholder="Enter the task details" style="width: 80%;">{{task.details}}</textarea>
                        
                    </div>
                    <div class="mb-3">
                      <label for="task-date" class="form-label  me-5">Date set curerntly: {{task.date}}</label>
                      <input type="date" name="date" class="form-control" id="task-date" style="width: 80%;" value="{{task.date}}">
