Ruby Forum Ruby on Rails > "uninitialized constant ActiveSupport" when running "rake db:migrate:reset" after including my own d

Hi,
When I include this line in my environment.rb file my Rails app works as
expected, HOWEVER using "rake:db:reset" then does not work after this???


 "ActiveSupport::CoreExtensions::Date::Conversions::DATE_FORMATS[:default] 
=
"%d/%m/%Y"

The rake exception that gets thrown is below.  Any ideas re how to get 
rake
working as obviously I want to be able to keep my own default date 
format?

rake aborted!

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.
