Avoid using a generic except block as it may catch unexpected exceptions, making it harder to debug. Use logging to record error messages and tracebacks for debugging purposes. Test error handling code to ensure it behaves as expected in different scenarios. Conclusion Effective error handling is ...
思路一: 直接在之前写好的查询所有课程的视图类上,配置一个类即可 class CourseView(GenericViewSet, CommonListModelMixin,CommonRetrieveModelMixin) 返回的字段,跟详情,不太对应(详情中要求拿出所有章节和课时,但实际上只返回了4个课时) 序列化类---》重写个详情的序列化类即可---》视图类中重写 get_serializer_...

try:do_something()except Exception:# THis will catch any exception!print("Something terrible happened") 为了合理准确的定义你的异常类,这里有一些规范与编程技巧,你可以做为参照: 必须继承 Exception类: class MyOwnError(Exception): pass 利用前面提到的BaseException.str: 它将传递给BaseException.init方法的...
Bug report Bug description: In Python 3.11.9, the following code does not raise an Exception: from typing import Any, Generic, TypeVar T = TypeVar("T") class DataSet(Generic[T]): def __setattr__(self, name: str, value: Any) -> None: obje...
Note: Catching a generic Exception, as in the example above, is considered a bad practice in Python. You should always try to find a specific exception to catch. This way, you’ll prevent hiding unknown errors. However, in this specific use case of raise, you may want to specify a broa...
