    You cannot use update_all with arrays, only with scopes. find or all (in older version of Rails) return an array. Instead:

    comments = Comments.scoped(:conditions => "test IS NOT NULL")
comments.update_all(:test => nil)

    On modern versions of Ruby/ActiveRecord, you can write:

    Comments.where.not(test: nil).update_all(test: nil)
