A library to create peewee model instances for testing.

Project description


No time? Ready to use?

pip install peewee-model-factory
from peewee_model_factory import model_factory
from model import Author, Book

author = model_factory(Author, fill_nullable_values=True)
book = model_factory(Book, author=author)

Need custom type generation?

import peewee as pw
from peewee_model_factory import model_factory

def char_field_factory(field: pw.Field) -> str:
    return f"my char value for field: {}"

field_type_map = {
    pw.CharField: char_field_factory,

def my_custom_model_factory(*args, **kwargs) -> pw.Model:
    return model_factory(*args, custom_field_type_map=field_type_map, **kwargs) 

Want to use with peewee-async?

import peewee as pw
from peewee_model_factory import model_factory
from peewee_async import Manager

manager = Manager(...)

def my_custom_model_factory(*args, **kwargs) -> pw.Model:
    with manager.allow_sync():
        return model_factory(*args, **kwargs) 


A library to create peewee model instances for testing. The project creation has been inspired by django-dynamic-fixture and peewee-fake_fixtures projects.


  • Recursevely creating models for foreign fields
  • An option for filling nullable values
  • Easy customization if you need to extend or change generation for types of peewee fields

Possible inconvenience

  • The project has no tests.
  • Not all field types of peeweee has factory function in the project. You have to write custom one if you want to use them
