ManyToManyRel' object has no attribute 'parent_model

[MUDASSARHASHMI]

In utils.py at following line its hard to understand its like "tuple + tuple + list".
fields = Model._meta.fields + Model._meta.many_to_many + Model._meta.get_all_related_objects()
This is caused me error so I converted it to tuple(Model._meta.get_all_related_objects()).
However now I am getting error with following traceback:
