Question

我已经开始使用django消息来创建项目。它非常适合创建添加新项目。

但..我希望每个动作都有功能 - 删除，创建，编辑（每个都有不同的按钮）我只有帖子功能..当我尝试创建一条消息表示该项目已被成功删除时，我真的很困惑。我怎么知道删除已提交而不是发帖？因为一切都通过后期功能。

PostEdit和Delete没有消息所需的“请求”。

所以现在我只使用每次创建服务器时运行的messages.succuess。我希望为删除，编辑，创建和错误提供不同的消息。

有没有人有线索？

index.html -

{% if messages %}
    <ul class="messages">
        {% for message in messages %}
        <div class="alert alert-success alert-dismissible fade show" role="alert">
                <li{% if message.tags %} class="{{ message.tags }}"{% endif %}>{{ message }}</li>
                <button type="button" class="close" data-dismiss="alert" aria-label="Close">
                    <span aria-hidden="true">&times;</span>
                </button>
            </div>
        {% endfor %}
    </ul>
    {% endif %}

views.py -

    model = serverlist
    form_class = HomeForm
    #messages.success(request,"The server has been edited successfully")
    #fields = ['ServerName','Owner','Project','Description','IP','ILO','Rack','Status']

    success_url = reverse_lazy('serverlist')

Answer 1

覆盖deleteview中的delete方法以更改消息类型：

class PostDelete(SuccessMessageMixin, DeleteView):
    model = serverlist
    success_url = reverse_lazy('serverlist')
    success_message = "Object deleted"
    def delete(self, request, *args, **kwargs):
        messages.warning(self.request, self.success_message)
        return super(PostDelete, self).delete(request, *args, **kwargs)

您可以通过覆盖UpdateView的更新方法来执行相同的操作。

Answer 2

class PostEdit(UpdateView):
    template_name = 'serverlist.html'
    model = serverlist
    form_class = HomeForm
    #messages.success(request,"The server has been edited successfully")

你不能像那样在类定义中调用messages.success。调用必须使用post或form_valid等方法。

消息框架有SuccessMessageMixin，您可能会发现它很有用。您将mixin添加到每个视图，并设置success_message：

class PostDelete(SuccessMessageMixin, DeleteView):
    model = serverlist
    success_url = reverse_lazy('serverlist')
    success_message = "Object deleted"
