更新视图不​​起作用？姜戈

Question

用户可以在此网址创建飞机帖子：

url(r'^upload/aircraft/$', aircraft_create, name="aircraft_create"),

我创建了一个显示所有用户帖子的摘要页面。他们可以在这里编辑和删除他们的帖子。网址：

url(r'^account/uploads/$', upload_overview, name="account_uploads"),

但是，我希望用户能够在他们的摘要页面上编辑他们的帖子。我现在设置它的方式是他们可以在upload/aircraft/edit 进行编辑，但我想成为account/uploads/edit。

我已经这样设置了，但它什么也没做？关于它可能是什么的任何线索？

Aircraft/views.py

def aircraft_create(request):
  form = aircraft_form(request.POST or None)
  if form.is_valid():
    instance = form.save(commit=False)
    instance.user = request.user
    instance.save()
    messages.success(request, "Your upload has been successfully added!")
    return HttpResponseRedirect(instance.get_absolute_url())
  else:
    messages.error(request, "There seems to be something wrong. Have a look again..!")
  context = {"form":form,}
  return render(request,'aircraft/aircraft_form.html', context)

更新视图

def aircraft_update(request, id=None):
  aircraft = get_object_or_404(Aircraft, id=id)
  form = aircraft_form(request.POST or None, instance=aircraft)
  if form.is_valid():
    form.save()
    messages.success(request, "Your edit has been successfully been saved!")
    return HttpResponseRedirect(aircraft.get_absolute_url())

  return render(request,'aircraft/aircraft_form.html',
    {"aircraft": aircraft, "form": form})

模板

  {% if UploadedAircraft %}
  {% for upload in UploadedAircraft %}
    <div class="col-lg-offset-0 col-md-4 col-sm-3 item">
        <div class="box"><a href="{{ upload.get_absolute_url }}"><img src="{{ upload.image.url }}" width="200px" height="200px" alt="{{ upload.title }}"/></a>
            <h3 class="name"><a href="{{ upload.get_absolute_url }}">{{ upload.name }}</a></h3>
            <a href="{% url 'aircraft_update' %}"><button class="btn">Edit</button></a>
            <a href="{% url 'aircraft_delete' %}"><button class="btn">Delete</button></a>
        </div>

摘要页面视图

def upload_overview(request):
    uploaded_aircraft = Aircraft.objects.filter(user=request.user)
    return render(request,'account/upload_overview.html',{'UploadedAircraft':uploaded_aircraft)

url.py

   #aircraft/detail/1
    url('^aircraft/detail/(?P<id>\d+)/$', aircraft_detail, name='aircraft_detail'),

    #account/uploads (Display Users uploads)
    url(r'^account/uploads/$', upload_overview, name="account_uploads"),

    #upload/aircraft (Create Aircraft)
    url(r'^upload/aircraft/$', aircraft_create, name="aircraft_create"),

    #Edit/aircraft
    url('^account/uploads/$', aircraft_update, name='aircraft_update'),

编辑

def airline_update(request, id=None):
  airline = get_object_or_404(Airline, id=id)
  form = airline_form(request.POST or None, instance=airline)
  if form.is_valid():
    form.save()
    return HttpResponseRedirect(airline.get_absolute_url())
  return render(request,'airline/airline_form.html',
    {"airline": airline, "form": form})

网址

#account/upload/edit/ (Edit airline)
url(r'^account/uploads/edit/(?P<id>[0-9]+)$', airline_update, name='airline_update'),

模板

<a href="{% url 'airline_update' id=upload.id %}"><button class="btn">Edit</button></a>

Answer 1

假设您正在尝试编辑具有特定 ID 的飞机，您需要在 url.py 中使用类似的内容（假设 ID 是整数）：

url('^account/uploads/edit/(?P<id>[0-9]+)$', aircraft_update, name='aircraft_update')

在您的模板中，您需要更新您的锚链接以包含 ID：

<a href="{% url 'aircraft_update' id=upload.id %}">

请注意，这假定upload 对象（在您的模板循环中）包含一个id 属性，并且id 属性对应于您要更新的飞机ID。 （您可能将此属性命名为其他名称。）

编辑：这足以执行 GET 请求。但是，我注意到您对aircraft_update 的视图定义也尝试检查表单是否有效。此表单在您的模板中的什么位置？它似乎不在您的循环中。
