Is there a way to determine (global variable) to determine whether I’m  
running rails in development or production within an application?

Thanks in advance …

Can check ENV[‘RAILS\_ENV’] which contains either ‘development’, ‘test’,  
‘production’.

This is better answered on the Rails mailing list, joinable from  
[http://lists.rubyonrails.org/mailman/listinfo/rails](http://lists.rubyonrails.org/mailman/listinfo/rails). The mailing  
list you posted to is about Ruby programming in general, which means  
that only _some_ of the people on this list care about Rails issues.  
I’m glad you got your answer, but please try to restrict Rails  
questions to the Rails list.
