在Django的管理页面上,我想在管理员单击对象的“删除”按钮时执行操作。换句话说,我想在到达“你确定吗?”之前执行一些代码。删除确认页面。

我意识到我可以覆盖此对象的模板页面,但我希望更容易(例如,覆盖模型或表单上的方法)。

有什么想法吗?

您可以覆盖ModelAdmin.delete_view()方法,例如:

class MyModelAdmin(ModelAdmin):
    def delete_view(self, request, object_id, extra_context=None):
        # if request.POST is set, the user already confirmed deletion
        if not request.POST:
            perform_my_action()
        super(MyModelAdmin, self).delete_view(request, object_id, extra_context)

我们可以使用django.shortcuts.redirect来中断删除,如下所示:

def check_del(self, object_id):
    produkt = Produkt.objects.get(id = object_id)
    if produkt.typsklepu_set.all():
        return False
    else:
        return True

def delete_view(self, request, object_id, extra_context=None):
    # if request.POST is set, the user already confirmed deletion
    if not request.POST and self.check_del(object_id):
        return super(ProduktAdmin, self).delete_view(request, object_id, extra_context)
    elif request.POST:
        return super(ProduktAdmin, self).delete_view(request, object_id, extra_context)
    else:
        msg = u'Can not delete this object.'
        messages.error(request, msg)
        return redirect('..')
