user = UserFactory.build()

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

# Returns a dict of attributes that can be used to build a User instance
attributes = UserFactory.attributes()

rebar - Rebar makes your Forms stronger

from rebar.testing import flatten_to_dict

form_data = flatten_to_dict(ContactForm())
form_data.update({
        'name': 'X' * 300,
    })
form = ContactForm(data=form_data)
assert(not form.is_valid())

The same for formsets

from rebar.testing import flatten_to_dict, empty_form_data

formset = ContactFormSet()
form_data = flatten_to_dict(formset)
form_data.update(
    empty_form_data(formset, len(formset))
)
