| 6 | 6 | And for this test, i need to do two separate migrations in `app`, then how can i do it in unit tests since `self.get_change` will only have one migration when i do `self.get_change([Readable], [Readable_with_no_fields, Book, Magazine])`. When I do local testings, two separate migrations(one is to create `Readable` with fields `title` and `name`, second one is to remove fields from `Readable` and add these two fields into inheriting models like `Book`, `Magazine`), will solve the issue. But if i do `self.get_change([Readable], [Readable_with_no_fields, Book, Magazine])`, the test case tells me that models are created before base fields are removed, which is different from what i have on local testings. |
