[Bug]: Creation of Geometry objects from other geometry objects not working

[arpit15]

Initial Checks

• I confirm that I'm using Pydantic V2

Description

Creation of a class containing annotated MultiPolygon fails with a list of Polygon with validation error. Hopefully this behavior could be supported by changing validation logic in GeometryField

Error

Example Code

from shapely import MultiPolygon, Polygon
from pydantic_shapely import GeometryField
from pydantic.dataclasses import dataclass

@dataclass
class MyClass:
    polys: Annotated[MultiPolygon, GeometryField()]

mpoly = MultiPolygon([Polygon(shell=((0.0, 0.0), (0.0, 1.0), (1.0, 1.0), (1.0, 0.0)))])
assert isinstance(mpoly, MultiPolygon)

obj = MyClass(polys=MultiPolygon([
    (
    ((0.0, 0.0), (0.0, 1.0), (1.0, 1.0), (1.0, 0.0)),
    [((0.1,0.1), (0.1,0.2), (0.2,0.2), (0.2,0.1))]
    )
]))

obj = MyClass(polys=[Polygon(shell=((0.0, 0.0), (0.0, 1.0), (1.0, 1.0), (1.0, 0.0)))])

I am wondering if there is any suggestion on this. Without updating the dependencies, I am afraid I can't use this library.

[Peter-van-Tol]

Thank you for considering to us this library. I'll be able to change the validators this weekend. I hope that this will be quick enough for your project.

Fixed in version 1.0.0a3, available on PyPi now! 🚀

[Peter-van-Tol]

It is merged to main, however the upload to pypi has failed. Will resolve tomorrow morning.

Mistake while pushing the updated pyproject.toml. The version has now been successfully uploaded to PyPi:
