Class Method Details

.camelize(term) ⇒ Object

By default, camelize converts strings to UpperCamelCase. If the argument to camelize is set to :lower then camelize produces lowerCamelCase.

camelize will also convert ‘/’ to ‘::’ which is useful for converting paths to namespaces.

'active_model'.camelize                # => "ActiveModel"
'active_model'.camelize(:lower)        # => "activeModel"
'active_model/errors'.camelize         # => "ActiveModel::Errors"
'active_model/errors'.camelize(:lower) # => "activeModel::Errors"

As a rule of thumb you can think of camelize as the inverse of underscore, though there are cases where that does not hold:

'SSLError'.underscore.camelize # => "SslError"

def camelize(term)
  string = term.to_s
  string.capitalize!
  string.gsub!(/(?:_|(\/))([a-z\d]*)/i) { "#{$1}#{$2.capitalize}" }
  string.gsub!('/', '::')
  string

end

.constantize(camel_cased_word) ⇒ Object

Tries to find a constant with the name specified in the argument string.

'Module'.constantize     # => Module
'Test::Unit'.constantize # => Test::Unit

The name is assumed to be the one of a top-level constant, no matter whether it starts with “::” or not. No lexical context is taken into account:

C = 'outside'
module M
  C = 'inside'
  C               # => 'inside'
  'C'.constantize # => 'outside', same as ::C
end

NameError is raised when the name is not in CamelCase or the constant is unknown.
