Instance Method Details

#has_moderated_association(*args) ⇒ Object

Will moderate the passed in associations if they are supported. Example: has_moderated_association(:posts, :comments). Also supports passing :all to moderate all associations, but I personally do not recommend using this option.

Parameters:

  • associations (Hash) —

    the associations to moderate
