Trouble with Acts_as_list::move_higher/lower

Rails
1

I have the model MessageBoard acts_as_list for Forum, but for some
reason, the function move_higher/lower doesn’t seem to do its job in
the test file I wrote for forum_test.rb:

def test_board_up
forum = Forum.new(:title => ‘basic’)
assert forum.valid?, “forum is invalid, expect more failures”
assert_equal forum.title, ‘basic’
board = []
#initialize three boards in this order: #1, #3, #2
#board array holds = [#1, #2, #3]
board[0] = forum.message_boards.build(:title => ‘#1’,
:description => ‘one’)
board[2] = forum.message_boards.build(:title => ‘#3’,
:description => ‘three’)
board[1] = forum.message_boards.build(:title => ‘#2’,
:description => ‘two’)
#save, just in case
forum.save

move the index #2 lower (so that it’s less than #3)

forum.message_boards[2].move_lower

and save.

forum.save
board_temp = forum.message_boards
board_temp.each{|b| puts "\ntest_board_up order #{b.title}"}
for num in 0..2
  assert_equal board_temp[num].title, board[num].title
  assert_equal board_temp[num].description, board[num].description
end
forum.destroy

end

def test_board_down
forum = Forum.new(:title => ‘basic’)
assert forum.valid?, “forum is invalid, expect more failures”
assert_equal forum.title, ‘basic’
board = []
#initialize three boards in this order: #1, #3, #2
#board array holds = [#1, #2, #3]
board[0] = forum.message_boards.build(:title => ‘#1’,
:description => ‘one’)
board[2] = forum.message_boards.build(:title => ‘#3’,
:description => ‘three’)
board[1] = forum.message_boards.build(:title => ‘#2’,
:description => ‘two’)
#save, just in case
forum.save

move the index #3 higher (so that it’s greater than #2)

forum.message_boards[1].move_higher

and save.

forum.save
board_temp = forum.message_boards
board_temp.each{|b| puts "\ntest_board_down order #{b.title}"}
for num in 0..2
  assert_equal board_temp[num].title, board[num].title
  assert_equal board_temp[num].description, board[num].description
end
forum.destroy

end

While it may be possible I confused myself with the first test, and
thus, see no activity there, the second test SHOULD result in some
change. I saved object forum before calling move_higher in the middle
index, then saved again. However, according to my puts statement,
nothing seemed to have happened at all in the middle index! Why is
that?

move_higher/lower are calling update_all : you’ll need to reload
forum.message_boards to see any change.

Ahhh…I see. Yes it works, thank you!

Out of curiosity, where can I find that method in the rails framework
documentation? Being able to see the source would really help!
