Answer 1

It's very hard (verging on impossible) to answer without seeing your actual code. The problem is clearly in _inherits definition in one of your models.

Most likely you mixed up _inherits and _inherit. While the later one can be a either a list or a single string, _inherits has to be a dictionary.

It seems you might have erroneously defined _inherits as a list (instead of dict), because you really intended to use _inherit.
