Hi,  
I’m trying to externalize the strings in my application, and have this  
in the environment.rb file  
APP\_TEXT =  
(HashWithIndifferentAccess).new(YAML::load(File.open("#{RAILS\_ROOT}/config/strings.yml"))),  
This works fine until I try to do the functional and unit tests, where I  
get an uninitialized constant HashWithIndifferentAccess (NameError).  
I’ve tried it with Hash.HashWithIndifferentAccess,  
Hash:HashWithIndifferentAccess, and Hash::HashWithIndifferentAccess and  
none of these work.  
Am I supposed to be including something somewhere inside of the tests?

Hi,

Do you put this line APP\_TEXT = …  
at the end or beginning of the environment.rb file?

First I put it right below  
require File.join(File.dirname( **FILE** ), ‘boot’)  
and then I tried moving it to  
Rails::Initializer.run do |config|  
APP\_TEXT =  
(HashWithIndifferentAccess).new(YAML::load(File.open("#{RAILS\_ROOT}/config/strings.yml")))  
however this does not work.

Rails::Initializer.run do |config|  
#standard stuff  
end

#my stuff  
APP\_TEXT = …

Thanks! that worked perfectly,  
I still don’t really understand why the error didn’t come up during  
development and only during the unit testing. But thanks a lot!

The reason why this is a good thing is that it means the code runs  
after Rails has been loaded. Given that HashWithIndifferentAccess is  
part of rails this is a good thing !

No problem - actually it is interisting question why it worked on the  
development environment but I don’t know the answer 😉
