如何从Django异步处理数据库写入（可能带有消息队列）？(How to process database writes asynchronously (maybe with a message queue) from Django?)

 发现了问题。 我写了一些错误的代码，试图在彼此内部实例化更多的模板视图。 
 
 我知道模板视图的限制纯粹与scrollview（当然还有stencilView类本身）有关，因为它是唯一一个继承这个类的人。 
 
 所以你不能在彼此内部实例化8个以上的scrollview，这看起来非常好。 
 
class stencilTest(App):
     def build(self):
        super(stencilTest, self).__init__()
        root = GridLayout(cols=1, spacing=10, size_hint_y=None)
        r = root
        for i in range(10):
            w = ScrollView(size_hint=(1, 1), size=(1000, 800))
            r.add_widget(w)
            r = r.children[0]       
        return root


if __name__ == "__main__":
     stencilTest().run()
 
 如果感兴趣，此代码将重现错误 

Found the problem. I wrote some bad code that was trying to instantiate more stencil view inside each other.
 
I understood that the limit of the stencil view is related purely to scrollview (and the stencilView class itself of course) because it's the only one to inherit this class.
 
So you can't instantiate more than 8 scrollview inside each other, which seems perfectly fine.
 
class stencilTest(App):
     def build(self):
        super(stencilTest, self).__init__()
        root = GridLayout(cols=1, spacing=10, size_hint_y=None)
        r = root
        for i in range(10):
            w = ScrollView(size_hint=(1, 1), size=(1000, 800))
            r.add_widget(w)
            r = r.children[0]       
        return root


if __name__ == "__main__":
     stencilTest().run()
 
This code will reproduce the error if interested
