Django:编写一个视图来删除带有复选框的项目

Question

我需要帮助编写一个获取POST数据的视图,然后找出已经检查了哪些复选框,然后从id匹配的数据库中删除项目.最初,这是一个复选框问题.在编辑订单表单中,有一个项目列表.现在我可以使用一些javascript删除该项目,但它没有得到保存,因为我需要从我的数据库完全删除它.我尝试使用我的编辑订单视图使用delete()删除项目,但这不起作用.一定有别的我做错了,但我不知道是什么.

delete_item = request.POST.get('delete_item', None)
    if request.method == 'POST':
        form = forms.OrderForm(request.POST, instance = order)
        if form.is_valid() and save_item is not None:
            form.save(True)
            request.user.message_set.create(message = "The order has been updated successfully.")
            return HttpResponse("<script language=\"javascript\" type=\"text/javascript\">window.opener.location = window.opener.location; window.close();</script>")

        if status is not None and contact is not None and save_status is not None and delete_item is not None:
            try:
                for id in status_items:
                    item = models.StorageItem.objects.get(pk = id)
                    delete = item
                    delete.delete()
                    current_status = models.ItemStatusHistory(item = item, contact = contact, status = status,
                                                    user = request.user)
                    current_status.save()
            except:
                pass
            request.user.message_set.create(message = "Status successfully changed for {0} items".format(len(status_items)))

{% for item in items %}
        <tr class="items_table_row">
                <td><input type="checkbox" name="item" value="{{item.pk}}" checked="checked"{% endif %}>
                <td>{{item.tiptop_id}}</td><td>{{item.alternative_id}}</td><td>{{item.title}}</td><td>{{item.type}}</td><td>{{item.format}}</td>
                <td><span id="{{item.pk}}" name="type">{{item.itemstatushistory_set.latest}}</span></td><td>{{item.itemstatushistory_set.latest.date.date|date:"d M Y"}}</td>
                <td><a href="{% url tiptop.views.edit_item item.client.pk item.pk %}" onclick="return showAddAnotherPopup(this);">Edit</a></td>
        </tr>
{% endfor %}

鉴于你的模板使用复选框name="item"... .delete()应该工作.

Items.objects.filter(id__in=request.POST.getlist('items')).delete()

你有例外吗？在delete()代码永远运行？扔一份印刷声明.

你有"大量的代码",我们不熟悉的很多条件,以及try/except块,所以我只想确保视图实际上是在删除阶段.

更新:作为代码的陌生人,这是一段粗略的代码.
if status is not None and contact is not None and save_status is not None and delete_item is not None:

为什么不检查是否存在按下的特定按钮？

# html
<input type="submit" name="save" value="Save Items" />
<input type="submit" name="delete" value="Delete Items" />

# view
if request.POST.get('delete'):
   Items.objects.filter(id__in=request.POST.getlist('items')).delete()
elif request.POST.get('save'):
   form = Form(request.POST)
# ... so on
