Kevin Brown e888fc11c7 Merge NullBooleanField with BooleanField(allow_null=True) (#7122) ... * Make `NullBooleanField` subclass `BooleanField` This removes a lot of the redundancy that was in place becuase we were not doing this. This maintains the `None` initial value that was previously present, as well as disallowing `allow_null` to be passed in. * Remove special case for mapping `NullBooleanField` In newer versions of Django, the `NullBooleanField` is handled the same way as a `BooleanField(null=True)`. Given that we also support that combination, and that our own `NullBooleanField` behaves in the same manner, it makes sense to remove the special casing that exists for it. * Add test for BooleanField(null=True, choices) * Remove special case for NullBooleanField * Adjust mapping tests for NullBooleanField * Fixed linting error * Raise deprecation warning when NullBooleanField is used * Fix linting issue in imports		2020-05-13 14:59:04 +01:00
