我们从Python开源项目中，提取了以下24个代码示例，用于说明如何使用django.contrib.messages()。
def message_user(self, message, level='info'): """ Send a message to the user. The default implementation posts a message using the django.contrib.messages backend. """ if hasattr(messages, level) and callable(getattr(messages, level)): getattr(messages, level)(self.request, message)
