pydantic-resolve 1.11.0

It just provide a pair of pre & post methods around pydantic fields, the rest is up to your imagination

Pydantic-resolve is a schema based solution for data management.

1. manage the deep data inside it's schema, instead of visiting if outside by manual traversal.
2. pydantic-resolve runs a Level Order Traversal (BFS) inside and execute resolve and post during this process.
3. describe the relationship between data in a way close to ERD (entity relationship diagram)

Install

User of pydantic v2, please use pydantic2-resolve instead.

This lib now supports both pydantic v1 and v2 starts from v1.11.0

pip install pydantic-resolve

Hello world

manage your data inside the schema.

class Tree(BaseModel):
    name: str
    number: int
    description: str = ''
    def resolve_description(self):
        return f"I'm {self.name}, my number is {self.number}"
    children: list['Tree'] = []


tree = dict(
    name='root',
    number=1,
    children=[
        dict(
            name='child1',
            number=2,
            children=[
                dict(
                    name='child1-1',
                    number=3,
                ),
                dict(
                    name='child1-2',
                    number=4,
                ),
            ]
        )
    ]
)

async def main():
    t = Tree.parse_obj(tree)
    t = await Resolver().resolve(t)
    print(t.json(indent=4))

import asyncio
asyncio.run(main())
