Django開發(fā)自定義拋出異常怎么辦

# 利用繼承自定義異常提示信息
class MyException(Exception):
  def __init__(self, code, error, data):
    self.code = code
    self.error = error

    raise MyException(1001, '你的說法錯誤', '1不小于0')
except MyException as e:
  pass

    # 自定義狀態(tài)碼
    self.code = 1000
    self.error = ''
    self.data = ''
 
  @property
  def dict(self):
    return self.__dict__

# 創(chuàng)建實(shí)例對象
one = MyTest()
one.code = 1001
one.error = '你錯了'
one.data = '請?jiān)俅螜z查'
 
print(one.dict)
