我尝试在写入DB之前从API输入中删除空格。

>>> class A(object):
...     def __init__(self, name, email, phone_number):
...             self.name = name
...             self.email = email
...             self.phone_number = phone_number
... 
>>> class ASerializer(serializers.Serializer):
...     name = serializers.CharField(max_length = 200, trim_whitespace=True)
...     email = serializers.EmailField()
...     phone_number = serializers.RegexField("[0-9]{10}")
>>> obj = Geeks("Aditi ", "abc@gmail.com", "1234567890 ")
>>> serializer = ASerializer(obj)
>>> serializer.data
{'name': 'Aditi ', 'email': 'abc@gmail.com', 'phone_number': '1234567890 '}

为什么不去掉名字上的空格呢？有什么想法吗？
