Once I start coding a rails app, I am by default in development mode.
What should I do to change my rails environment to test or production mode ?
can I work in multiple environments simultaneously ?

A:
It depends how you are running the application. When you run your tests then they automatically use the test environment. If you are using script/server (e,g, using WEBrick, Mongrel etc.) then you can pass the name of the environment to use on the command line e.g. script/server -e production.
If you are using Phusion Passenger then the environment can be specified using the RailsEnv configuration directive
If you are using the Rails console then specify the environment name directly:
script/console productionYou can create your own environments too. This Railscast has the details

if you want to run both development and production the same time, you must change the port, so that the 2 instances are not trying to use the same one:`script/server -p 3001 RAILS_ENV=production`

suppose if I run a unit test by saying like ruby unit/post-test.rb , will rails automatically know that I want to use test environment... after all we are running just a ruby file by a simple ruby command.. how can rails know about this ?

A:
to run application on production mode type in console
ruby script/server -e production
TO RUN SAME APPLICATION ON DIFFERENT ENVIORMENT you have to use different ports
like
ruby script/server -e production -p 3001
AND
ruby script/server -p 3002

if I run my app in production mode, it gives me an error like "table posts not available" .. where as its already there and was working during development mode..

Check your database.yml . The production environment probably uses a different database then the development mode . "rake db:create RAILS_ENV =production" and then "rake db:migrate RAILS_ENV=production" should set up the db for production as well .

A:
script/server -e production for production mode
more in script/server --help
