How do I set my rails 3 app to development mode?

问题

I need to set my rails 3 app on DreamHost to development mode.

In rails 2.3, I used to set it at environment.rb. How and where do I do that for rails 3?

Thanks.

Like Ikahtz says, but:

# in config/environment.rb
ENV['RAILS_ENV'] = 'development' 

回答2:

add this to your environment.rb:

ENV['RAILS_ENV'] ||= 'development'

As far as I know setting your Rails environment via RAILS_ENV wouldn't help you on a DreamHost shared server because they are running their Passenger strictly with the production environment.
