python - 在 factory_boy 中更改默认的 faker 语言环境

Question

如何在 Python 的 factory_boy 中为我的所有工厂设置默认语言环境？

在文档中说应该用 factory.Faker.override_default_locale 设置它，但这对我的伪造者没有任何作用......

import factory
from app.models import Example
from custom_fakers import CustomFakers

# I use custom fakers, this indeed are added
factory.Faker.add_provider(CustomFakers)
# But not default locales
factory.Faker.override_default_locale('es_ES')

class ExampleFactory(factory.django.DjangoModelFactory):
    class Meta:
        model = Example

    name = factory.Faker('first_name')


>>> from example import ExampleFactory
>>> e1 = ExampleFactory()
>>> e1.name
>>> u'Chad'

Answer 1

Faker.override_default_locale() 是一个上下文管理器，尽管文档中不是很清楚。

因此，要更改部分测试的默认语言环境:

with factory.Faker.override_default_locale('es_ES'):
    ExampleFactory()

对于整个测试:

@factory.Faker.override_default_locale('es_ES')
def test_foo(self):
    user = ExampleFactory()

对于所有测试(Django):

# settings.py
TEST_RUNNER = 'myproject.testing.MyTestRunner'

# myproject/testing.py
import factory
from django.conf import settings
from django.util import translation
import django.test.runner

class MyTestRunner(django.test.runner.DiscoverRunner):
    def run_tests(self, test_labels, extra_tests=None, **kwargs):
        with factory.Faker.override_default_locale(translation.to_locale(settings.LANGUAGE_CODE)):
            return super().run_tests(test_labels, extra_tests=extra_tests, **kwargs)
