Django: How to create a model dynamically just for testing

Question

I have a Django app that requires a settings attribute in the form of:

RELATED_MODELS = (\'appname1.modelname1.attribute1\',
                  \

I shared my solution that I use in my projects. Maybe it helps someone.

pip install django-fake-model

Two simple steps to create fake model:

1) Define model in any file (I usualy define model in test file near a test case)

from django_fake_model import models as f


class MyFakeModel(f.FakeModel):

    name = models.CharField(max_length=100)

2) Add decorator @MyFakeModel.fake_me to your TestCase or to test function.

class MyTest(TestCase):

    @MyFakeModel.fake_me
    def test_create_model(self):
        MyFakeModel.objects.create(name='123')
        model = MyFakeModel.objects.get(name='123')
        self.assertEqual(model.name, '123')

This decorator creates table in your database before each test and remove the table after test.

Also you may create/delete table manually: MyFakeModel.create_table() / MyFakeModel.delete_table()
