Can't mass-assign protected attributes: score, trigram, owner_type

[chrilleferna]

When creating a new or editing an existing object whose class model has a fuzzy_searchable attribute I get a mass assignment violation error. This happens when I do an "update_attributes" with a hash, even if the hash does not contain any of the attributes (score, trigram, owner_type). If I change the "update_attributes", the error appears at save. I use Rails 3.2.12 with Ruby 1.9.3

Oh, andI tried adding attr_accessible for the three attributes after the call to fuzzily_searchable in my model, but it didn't change anything
