Method: String#camelize

Defined in:
lib/active_support/core_ext/string/inflections.rb

#camelize(first_letter = :upper) ⇒ Object Also known as: camelcase

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_record'.camelize                # => "ActiveRecord"
'active_record'.camelize(:lower)        # => "activeRecord"
'active_record/errors'.camelize         # => "ActiveRecord::Errors"
'active_record/errors'.camelize(:lower) # => "activeRecord::Errors"

See ActiveSupport::Inflector.camelize.
