v1.0.0

I'm excited to announce ODMantic v1.0.0, with Pydantic v2 support! 🎉

This release brings a range of changes that are aligned with the new Pydantic architecture.
Keeping a maintainable and healthy codebase was especially important.
Thus from now on, ODMantic will not support Python 3.7, Pydantic V1, and Motor 2.x anymore.

Overall, integrating with Pydantic v2 brings around 30% performance improvements on
common operations. ⚡️⚡️⚡️

We have a lot of room to improve the performance further now that we only support Pydantic v2.
There is also a 300% 👀 improvement on the bulk saves crafted by @tiangolo that will be merged soon! 🚀

Special thanks to @tiangolo for his help on this release and for saving me a lot of time
figuring out a particularly annoying bug!

Check out the migration guide to
upgrade your codebase and enjoy this new release!

Breaking changes

• Support for Python 3.7, Pydantic v1 and Motor 2.x has been dropped

• Optional[T] doesn't have a None implicit default value anymore

• Model.copy doesn't support the exclude and include kwargs anymore

• odmantic.Field doesn't accept extra kwargs anymore since it's slated to be removed in Pydantic

• The Config class is no longer supported and the model_config dict should be used instead

• DocumentParsingError is no longer a subclass of ValidationError

• The __bson__ class method is no longer supported to define BSON encoders on custom types. The new method to customize BSON encoding is to use the WithBSONSerializer annotation.

• Decimals (decimal.Decimal and bson.Decimal128) are now serialized as strings in JSON documents

• Custom JSON encoders(defined with the json_encoders config option) are no longer effective on odmantic.bson types. Annotated types with pydantic.PlainSerializer should be used instead.

Removals

• AIOEngineDependency has been removed since it was deprecated in v0.2.0 in favor of a global engine object

• Defining the collection with __collection__ has been removed since it was deprecated in v0.3.0 in favor of the collection config option

Deprecations

We comply with the new Pydantic method naming, prefixing them with model_

• Model.dict has been deprecated in favor of Model.model_dump

• Model.doc has been deprecated in favor of Model.model_dump_doc

• Model.parse_doc has been deprecated in favor of Model.model_validate_doc

• Model.update has been deprecated in favor of Model.model_update

• Model.copy has been deprecated in favor of Model.model_copy
