Django-消息功能在基于类的视图中不起作用 [英] Django - Messages functionality not working in Class based view

问题描述

无法在基于类的视图中显示消息.在另一个应用程序的views.py中，在我使用基于函数的视图的地方它可以正常工作.

Unable to display messages in class based view. In another app's views.py, it is working fine where I used function based view.

views.py:

class PostDeleteView(LoginRequiredMixin, UserPassesTestMixin, SuccessMessageMixin, DeleteView):
        model = Post
        success_url = '/user-profile/'
        success_message = "Your post has been deleted sucessfully!"
    
        def test_func(self):
            post = self.get_object()
            if self.request.user == post.author:
                return True
            return False
            

urls.py:

path('user-profile/', user_views.user_profile, name='user_profile'),

html:

{% if messages %}
        {% for message in messages %}
        <div class="alert alert-{{ message.tags }}">
            {{ message }}
        </div>
        {% endfor %}
{% endif %}

推荐答案

DeleteView 不继承 FormView 的子类，因此 SuccessMessageMixin 不会做任何事情.您将需要自己添加消息，覆盖 delete 方法似乎是个好地方

DeleteView does not subclass FormView so SuccessMessageMixin will not do anything. You will have to add the message yourself, overriding the delete method seems like a good place

def delete(self, request, *args, **kwargs):
    response = super().delete(request, *args, **kwargs)
    messages.success(self.request, 'Your post has been deleted sucessfully!')
    return response
