Hi @Allan-Nava. As has been pointed out to you several times, the GitHub issue tracker is intended for bug reports and feature requests. If you need help or support, there are a few places to ask questions, such as IRC, Stack Overflow, and the Google Group.

Also, please read the error in your stack trace.

TypeError: Ingrediente() got an unexpected keyword argument 'many'

It looks like you've passed your serializer_class to your model class, which is incorrect.

Just a cut and paste error on my part, so change serializer_class = MyModelName to serializer_class = MyModelNameSerializer in your viewset.
