Are there 3 forms to invoke production, staging, etc in Ruby on Rails for rails server, rails console, and rake? -

The forms I know are:

For Rail 3.0: Rail Server -

Rail Console

  Rail Console Production  
 rake for  
  rake db: RAILS_ENV = Migrate output  
 
 What is this? I know for  train runner  and  rail debic console , this is also  -e production  what are more forms and what other things are < Use code> -e , just name or need  RAILS_ENV ? 
 
 As a sidenote, why is so complex; Is it to increase the difficulty so that electricity is hugged in consultation and more charges? (As in the school they teach you to use simple words to teach you, but in the real world, people use harsh words to gain power.) 
 

You do not say which platform you are using, but * on the nick machine, if you want to be consistently, always Occurs:

RAILS_ENV = test rail server

Receive whatever you want.

For the reasons behind the inconsistencies, I do not think you have developer taste, laziness, etc.
