Instance Method Details

#base_permitted_attributes ⇒ Array<Symbol>

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

These are the attributes that we assume all “work type” classes (e.g. the given :klass) will have in addition to their specific attributes.

Returns:

  • (Array<Symbol>)

  • #permitted_attributes

#create ⇒ Object

An ActiveFedora bug when there are many habtm <-> has_many associations means they won’t all get saved. github.com/projecthydra/active_fedora/issues/874 2+ years later, still open!
