What's this?

camelize(lower_case_and_underscored_word, first_letter_in_uppercase = true) public

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

Examples

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

    if first_letter_in_uppercase
      lower_case_and_underscored_word.to_s.gsub(/\/(.?)/) { "::" + $1.upcase }.gsub(/(^|_)(.)/) { $2.upcase }
    else
      lower_case_and_underscored_word.first + camelize(lower_case_and_underscored_word)[1..-1]
    end
  end
