Как вариант:
Если name_mapping - список, а не словарь, дампить в список.
При этом все неуказанные поля добавлять в порядке их следования в исходном классе.
@dataclass
class A:
first: int
second: int
Если взять схему:
schema = Schema(
name_mapping=[]
)
Превратит объект A(1,2) в [1,2]
Если взять схему:
schema = Schema(
name_mapping=['second']
)
Превратит объект A(1,2) в [2,1]
Если взять схему:
schema = Schema(
name_mapping=['second'],
only_mapped=True,
)
Превратит объект A(1,2) в [2]
Проблема: нельзя сделать иерархию внутри списка как в случае с маппингом. Но возможно это и не нужно.
from adaptix.
В текущий момент возможно сделать список из датакласса указав ВСЕ необходимые поля в name_mapping в виде
schema = Schema(name_mapping={
"first": (0, ),
"second": (1, )
})
from adaptix.
Now we have mapping to list
