Django specific Extensions for Factory Boy

Project description

FactoryMan

FactoryMan provides Django specific extensions for Factory Boy.

Installation

pip install factory-man

Usage

FactoryMan provides you with a factory function create_populated_modelfactory, which accepts the model class and automatically creates a factory class based on the model's fields. If you want to override some fields, you can pass them as keyword arguments to the __init__ method.

from factoryman import create_populated_modelfactory
from .models import Project

ProjectFactory = create_populated_modelfactory(Project)

ExpiredProjectFactory = create_populated_modelfactory(Project, deadline='1999-04-04')

To override the factory's _create method, use create_override keyword argument. This is useful to create many-to-many connections as described in the Factory Boy documentation.

Check out this article for a more detailed user guide.

Low-level Features

ModelFieldSequence extends factory.Sequence to provide a little more DRY syntax. It accepts a Django model class as parameter and uses the class name togeteher with the field name to which it is bound to for creating an unique value.

Alternatively, it can accept a string parameter, which will be used directly instead of a name derived from the class and field.

Example:

from factory.django import DjangoModelFactory as ModelFactory
from factoryman import ModelFieldSequence


class CharityFactory(ModelFactory):
    class Meta:
        model = Charity

    name = ModelFieldSequence(Charity)  # Will be `Charity__name-n`, where n is the object count
    email = ModelFieldSequence(string='hello@charity.ee')  # Will be `hello@charity.ee-n`, where n is the object count
