A simple MyFactory.create() actually not saving in DB? (Django)

Hello,

I just gave a try to factory_boy, and it fails to actually save my model in DB.

Here’s my model:

# myapp.models.py
from custom_user.models import AbstractEmailUser


class User(AbstractEmailUser):
    class Meta:
        verbose_name = _(u'Utilisateur')

Here’s my factory:

# myapp.factories.py
import factory

from myapp.models import User


class UserFactory(factory.Factory):
    class Meta:
        model = User

    email = factory.Sequence(
        lambda n: '[e-mail]' % n)

What I’m reading from the docs:

# Returns a saved User instance
user = UserFactory.create()

And here’s how I’m trying to use the whole thing:

• Vanilla style, everything works just fine:

In : User.objects.all().count()
Out: 15
In : User.objects.create(email="[e-mail]")
In : User.objects.all().count()
Out: 16

• With factory_boy:

In : User.objects.all().count()
Out: 16
In : user_created_with_factory = UserFactory()
In : User.objects.all().count()
Out: 16
In : user_created_with_factory.id
In : user_created_with_factory.email
Out: '[e-mail]'

That’s where it should return 17 for user_created_with_factory.id I also tried with UserFactory.create() instead of UserFactory(), same result. Of course, if I try user_created_with_factory.save(), I’ll have my instance in DB and have an ID…

My env: python: 2.7.6 Django: 1.10 Pip: pip 1.5.4 Virtualenv: 1.11.4 factory-boy: 2.7.0

Any ideas of what could be wrong with my procedure !? Thanks

Hi!

If you work with Django models, you need to use factory.django.DjangoModelFactory — otherwise, factory_boy uses the “simple Python object” approach.

Note that factory_boy also supports other ORMs (SQLAlchemy, …).

Hope this helps!

@jyr since this issue has already been closed, it would be easier for us to track it if you open a separate issue.

Also, your use of location = LocationFactory() won’t work the way you expect it to; you should be using location = factory.SubFactory(LocationFactory).
