how to change rails to development mode

Question

In the documentation of rails (3.2.3) it says

In development mode (which is what you’re working in by default), Rails reloads your application with every browser request, so there’s no need to stop and restart the web server.

But clearly my app loads in production mode out of the box.(I can type Rails.env and see it).

Why?

I then go to environment.rb and add

ENV["RAILS_ENV"] = "development"

and still it is in production. Any idea?

Edit : Here you go

#Load the rails application
require File.expand_path('../application', __FILE__)

# Initialize the rails application
MyAppName::Application.initialize!

ENV["RAILS_ENV"] = "development"

Answer 1

Possible solution for your situation could be:

rails server -e development

Answer 2

Though this is not a solution try to start the Rails server this way:

RAILS_ENV=development bundle exec rails s

What do you see if put <%= Rails.env %> somewhere in you layout file?
