Using factory.load(data, _cls)
with missing fields in data
and no defaults for fields in _cls
will result in TypeError. Would like to see custom Exception like MissingFieldError
Example:
from dataclasses import dataclass
import dataclass_factory
@dataclass
class Book:
title: str # <--- No default values
price: int
data = {} # <--- Missing fields
factory = dataclass_factory.Factory()
book: Book = factory.load(data, Book) # Results in __init__() missing 2 required positional arguments: 'title' and 'price'
serialized = factory.dump(book)
Expected:
factory = dataclass_factory.Factory()
try:
book: Book = factory.load(data, Book)
serialized = factory.dump(book)
except MissingFieldError as e:
print(f"Fields {e.fields} are missing.")

Errors in 3.x are more verbose than requested
from adaptix.
