Dataclass field attributes

The following attributes can be set with fields in dataclass. For example,

>>> @dataclass
... class A:
...     a: int
...     b: str = field(metadata = {"perde_skip": True})

• perde_rename: "name"
  • Serialize and deserialize the field with the given name instead of the name in Python.
• perde_default: True
  • When deserialzing, if the field is missing, the field is created by its default constructor.
• perde_flatten: True
  • Flatten the content of this field.
  • The type of the field can be either dataclass or dictionary.
  • If the type is dictionary, all the remaining fields at that point of deserialization are consumed.
• perde_skip: True
  • Skip serializing or deserializing this field.
  • The field must have default/default_factory, or the perde attribute default/perde_default set.
• perde_skip_serializing: True
  • Skip serialzing this field.
• perde_skip_deserialzing: True
  • Skip deserializing this field.
  • The field must have default/default_factory, or the perde attribute default/perde_default set.
