rails_environment

Error-free convenience methods for determining the running Rails environment.

This gem enables code like:

if RailsEnvironment.production?
   <do_production_only_stuff>
end

This prevents typos like:

if Rails.env == 'productoin' ...
if Rails.env.productoin? ...

So we get a runtime error if we misspell an environment instead of a silent bug.

For standard Rails applications with development, test and production environments you get:

Predicate method for each environment

• RailsEnvironment.development?
• RailsEnvironment.test?
• RailsEnvironment.production?

Negated predicate methods

• RailsEnvironment.not_development?
• RailsEnvironment.not_test?
• RailsEnvironment.not_production?

You can also "or" the environments, and negate the "or"'s

• RailsEnvironment.test_or_production?
• RailsEnvironment.not_test_or_production?
• etc.

Short and Long environment names

RailsEnvironment.short  #=> 'DEV'
RailsEnvironment.long   #=> 'Development'

# customize the short/long names
RailsEnvironment.environment_strings['development']['short'] = 'DVL'
RailsEnvironment.short  #=> 'DVL'

• The methods available are based on the actual environments, i.e., ../config/environments/*.rb
• If you add/remove a file in ../config/environments you will need to restart your server
