[Nitro] in... vain...

[Emmanuel Piperakis]

Dear list,
I have posted the same problem in the past, and I have been reassured that 
in 0.25 it would be fixed... here is a bit of code that illustrates the 
problem...

1 require 'rubygems'
       2 require 'og'
       3
       4 # Model
       5 class Foo
       6 property :name, String
       7 has_many Bar
       8 end
       9
      10 class Bar
      11 property :name, String
      12 belongs_to Foo
      13 has_many Foobar
      14 end
      15
      16 class Foobar
      17 property :name, String
      18 belongs_to Bar
      19 end
      20
      21 # Init
      22 Og.setup(
      23     :destroy => true,
      24     :store => :sqlite,
      25     :name => 'test'
      26   )
      27
      28 # preparing Tests
      29
      30 2.times{|i|
      31   foo = Foo.new
      32   foo.name = "foo #{i}"
      33   foo.save
      34 }
      35 Foo.all.length
      36
      37 3.times{|i|
      38   bar = Bar.new
      39   bar.name = "bar #{i}"
      40   bar.save
      41 }
      42 Bar.all.length
      43
      44 6.times{|i|
      45   foobar = Foobar.new
      46   foobar.name = "foobar #{i}"
      47   foobar.save
      48 }
      49 Foobar.all.length
      50
      51 foo1 = Foo[1]
      52 bar1 = Bar[1]
      53 bar1.add_foobar Foobar[1]
      54 bar1.add_foobar Foobar[2]
      55 bar1.add_foobar Foobar[3]
      56 bar1.save
      57 foo1.add_bar    bar1
      58 foo1.save
      59
      60 foo2 = Foo[2]
      61 bar2 = Bar[2]
      62 bar3 = Bar[3]
      63 bar2.add_foobar Foobar[4]
      64 bar3.add_foobar Foobar[5]
      65 bar3.add_foobar Foobar[6]
      66 bar2.save
      67 bar3.save
      68 foo2.add_bar bar2
      69 foo2.add_bar bar3
      70 foo2.save
      71
      72 # this work...
      73 ar = Array.new
      74 foo1.bars.each {|ii|
      75   ar.push(ii.foobars)
      76 }
      77
      78 ar.flatten!
      79 ar.size
      80
      81 # next line should work, but it does not
      82 foo_foobars = foo1.bars.foobars
      83 foo_foobars.class


even though foo1.bars is a collection foo1.bars.foobars does not work,
nor foo1.bars.find_foobars
