Witam,
mam taki problem, otóż mój model wygląda tak:
class EducationLevel < ActiveRecord::Base
validates :name, :presence => true, :uniqueness => true
serialize :hold_levels, Array
def hold_levels
read_attribute(:hold_levels) || []
end
def hold_levels=(perms)
perms = perms.collect {|p| p.to_sym unless p.blank? }.compact.uniq if perms
write_attribute(:hold_levels, perms)
end
end
i wykonując serie poleceń w konsoli:
e = EducationLevel.new(:name => “test”)
e.hold_levels = [“1”,“2”]
e.save
otrzymuję błąd:
ArgumentError: wrong number of arguments (2 for 1)

Bardzo proszę o pomoc.
