Where is Q2 defined ?

Fred

Q2 is my own class located in /app/models/Q2.rb

the content of it is

class Q2
COUNTRIES = {
‘AT’ => ‘Österreich’,
‘DE’ => ‘Deutschland’,
‘CH’ => ‘Schweiz’
}
end

on my development machine this class is loaded fine. everything is fine
on the development machine … i have no clue how to find this bug.
i owe you a beer for your help :wink:

do you need more information?

Change your filename to q2.rb
I’ll bet a beer that your development machine has a non case sensitive
filesystem whereas your servers do have case sensitive filesystems

a lot for spending your time with this …

conclusion: all my files should be lower case?

As far as the rails conventions go, it’s lowercase all the way
