Hi, I have a remote website that will be sending me some data which I want to save in one of my models. The problem is that it will also send some attributes such as attribute_1, attribute_2, etc which I don't want to save. Currently if I do: my_model.create(params), it will not pass as it has hash keys that don't map to any attribute in the model, how to make my model skip these unknown attributes in a clean manner?

You'd be better off cleaning up the params hash, eg with something like cleaned_params = params.slice(*Model.column_names) Fred
