Okay, I found a solution. It isn't very readable, but it works:
user = User.new(:login=> "foo", :password=>"bar") # :password is not
a column in the db, but defined in the model using
"attr_accessor :password" (see initial post)
[:login, :password].each do |x|
getter = x # => :password
setter = (x.to_s << "=").to_sym # => :password=
original_val = user.method(getter).call
user.method(setter).call(some_new_val)
do_some_test(user)
user.method(setter).call(original_val)
end
Any clean up suggestion?
