Hi,

When I change date formats via the following entry in environments.rb  
it works fine. Web pages reflect the new date format.  
“ActiveSupport::CoreExtensions:📅:Conversions::DATE\_FORMATS[:default]”

The issue is when I run things like “./script/console”, or  
"./script/spec " I get a “NameError: uninitialized constant  
ActiveSupport” issue. Any ideas how to solve this?

Macintosh-2:myequity greg$ ./script/console

oh…I see there was an answer to this in a previous forum post that  
solves this:

looks like you’ve put the ActiveSupport line inside the  
Rails::Initializer.run block.  
you need to put it at the end of your environment.rb file, else  
ActiveSupport hasn’t yet been loaded… hence the exception it raises.
