A New Overview in our Dashboard
We redesigned Socket's first logged-in page to display rich and insightful visualizations about your repositories protected against supply chain threats.
This library offers powerful mock data generation capabilities for pydantic
based models, dataclasses
and TypeDict
s. It can also be used with other libraries that use pydantic as a foundation.
Check out the documentation 📚.
pip install pydantic-factories
from datetime import date, datetime
from typing import List, Union
from pydantic import BaseModel, UUID4
from pydantic_factories import ModelFactory
class Person(BaseModel):
id: UUID4
name: str
hobbies: List[str]
age: Union[float, int]
birthday: Union[datetime, date]
class PersonFactory(ModelFactory):
__model__ = Person
result = PersonFactory.build()
That's it - with almost no work, we are able to create a mock data object fitting the Person
class model definition.
This is possible because of the typing information available on the pydantic model and model-fields, which are used as a source of truth for data generation.
The factory parses the information stored in the pydantic model and generates a dictionary of kwargs that are passed to
the Person
class' init method.
This library is open to contributions - in fact we welcome it. Please see the contribution guide!
