I'm using Instant Rails on windows. I'm also using ruby debug.
I first stumbled across the problem when an array that I named utilities_used = was misbehaving. I added some experimental code and set a breakpoint and started to investigate.
Here's my code (it's inside a model file):
foo = ufoo = vfoo = utfoo = utifoo = utils = utils_foo = foo_used = utils_used = missing_vehicles =
debugger
When I break into the debugger: (rdb:94) foo (rdb:94) vfoo (rdb:94) foo_used (rdb:94) missing_vehicles (rdb:94) ufoo #1 E:/InstantRails-2.0-win/rails_apps/Carbon Salon Source Tree/app/ controllers/admin_controller.rb:37 in 'receive_file' (rdb:94) foo NameError Exception: undefined local variable or method `foo' for #<AdminController:0x46b45b4> (rdb:94) vfoo NameError Exception: undefined local variable or method `vfoo' for #<AdminController:0x46b45b4> (rdb:94) foo_used NameError Exception: undefined local variable or method `foo_used' for #<AdminController:0x46b45b4> (rdb:94) missing_vehicles NameError Exception: undefined local variable or method `missing_vehicles' for #<AdminController:0x46b45b4>
Note that, as soon as I inspect an array who's name starts with the letter 'u', everything goes to pot...
I tinkered with this some more: Code: foo = ['a', 'b', 'c'] ufoo = ['d', 'e', 'f'] missing_vehicles =
foo.each {|f| puts f} ufoo.each {|u| puts u}
Console output: Processing AdminController#receive_file (for 127.0.0.1 at 2008-11-10 16:58:09) [POST] Session ID: 858773c8b3335d4c6e9a1326e17c7cd0 Parameters: {"user_data_file"=>#<ActionController::UploadedStringIO: 0x42920a8>, "action"=>"receive_file", "authenticity_token"=>"8 ce751d807f83817a140eb1cc4e463cc8f5b20f0", "controller"=>"admin"} a b c d e f E:/InstantRails-2.0-win/rails_apps/Carbon Salon Source Tree/app/models/ user_data_file.rb:95 #end
so - the code itself seems to work, back to the debugger:
(rdb:98) foo ["a", "b", "c"] (rdb:98) ufoo #1 E:/InstantRails-2.0-win/rails_apps/Carbon Salon Source Tree/app/ controllers/admin_controller.rb:37 in 'receive_file' (rdb:98) foo NameError Exception: undefined local variable or method `foo' for #<AdminController:0x426b46c> (rdb:98)
So - it seems to be a problem with the debugger, rather than with ruby. In fact, now that I think of it, i've repeatedly experienced bizarre behaviour when using the debugger to inspect variables that begin with the letter 'u'. Anybody else seen this?
I'm new to RoR, so - maybe i'm doing something stupid here... any input, enlightenment would be very much appreciated.
