kwargs_obj 1.0.0

将**kwargs映射到属性

在此处，您可以了解如何将**kwargs映射到您的属性

class Xex(KwargsObj):
    def __init__(self, **kwargs):
        self.something = None
        self.something_else = None

        self._kwargs_to_attributes(kwargs)

这将允许传递设置something_else和something_different的参数

>>> x = Xex(something=True)
>>> x.something
True

禁用未设置属性的设置

>>> x = Xex(asd=True)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 5, in __init__
  File "kwargs_obj/kwargs_obj.py", line 61, in _kwargs_to_attributes
    "Can't set %s parameter - it is not defined here!" % key
ValueError: Can't set asd parameter - it is not defined here!

禁用未设置属性的设置

修改了.__setattr__()方法，该方法禁用设置新属性。这可能对于数据容器来说是个好主意。

可以通过设置._all_set属性来触发修改.__setattr__()的功能

class Xex(KwargsObj):
    def __init__(self):
        self.something = None
        self.something_else = None

        self._all_set = True

现在将无法设置新属性，这可能有助于防止拼写错误

>>> x = Xex()
>>> x.asd = True
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "kwargs_obj/kwargs_obj.py", line 50, in __setattr__
    raise ValueError("%s is not defined in this class!" % name)
ValueError: asd is not defined in this class!

但您仍然可以重新定义已定义的属性

>>> x.something = True
>>>
