Getting an error when running makemigrations when 'django-restapi-engine' is specified as one of the databases:

The makemigrations command uses database introspection to check if tables are created. This requires a cursor which is not implemented on purpose. However to solve this we need to return a fake cursor with connect and close. Secondly we need to fake get_table_list the DatabaseIntrospection class as well.

File django_restapi_engine/base.py

class DatabaseWrapper(BaseDatabaseWrapper):

    [...]

    def create_cursor(self, name=None):
        return self  # Return self as fake cursor

    def connect(self):
        pass

    def close(self):
        pass


class DatabaseIntrospection(BaseDatabaseIntrospection):
    def get_table_list(self, cursor):
        return []
