pydantic_decoder
Convert json text back into proper Pydantic models.
Simple Example
from pydantic_decoder import DecoderModel, encode, decode
class MyModel(DecoderModel):
first_name: str
last_name: str
model = MyModel(first_name='John', last_name='Doe')
msg = model.json()
m = model.decode(msg)
assert m == model
assert isinstance(m, MyModel)Registration Examples
Use your current models by only changing the inheritance from pydantic.BaseModel to pydantic_decoder.DecoderModel.
from pydantic_decoder import DecoderModel, register_model, encode, decode
class MyModel(DecoderModel):
first_name: str
last_name: str
class MyModel2(DecoderModel):
first_name: str
last_name: str
# Subclasses of the DecoderModel are registered automatically
# register_model(MyModel)
# register_model('Model2', MyModel2)
model = MyModel(first_name='John', last_name='Doe')
msg = encode(model)
m = decode(msg)
assert m == model
assert isinstance(m, MyModel)
model2 = MyModel2(first_name='John', last_name='Doe')
msg = encode(model2)
m2 = decode(msg)
assert m2 == model2
assert isinstance(m2, MyModel2)
