Instance Method Details

#camelize_keys(options = {}) ⇒ ::Hash

Change keys to CamelCase without changing the original hash

Examples:

hash = { first_key: 1, 'second_key' => 2 }
hash.camelize_keys # returns {
                   #   FirstKey: 1,
                   #   'SecondKey' => 2
                   # }
hash = { first_key: 1, 'second_key' => 2 }
options = { uppercase_first_letter: false }
hash.camelize_keys(options) # returns {
                            #   firstKey: 1,
                            #   'secondKey' => 2
                            # }

Parameters:

  • options (::Hash) (defaults to: {}) —

    options of camelization

Options Hash (options):

  • uppercase_first_letter: (::Boolean) —

    flag defining the type of CamelCase

Returns:

  • (::Hash) —

    new hash with changed keys

def camelize_keys(options = {})
  dup.camelize_keys!(options)
end

#camelize_keys!(options = {}) ⇒ ::Hash

Change keys to CamelCase changing the original hash

Examples:

hash = { first_key: 1, 'second_key' => 2 }
hash.camelize_keys # returns {
                   #   FirstKey: 1,
                   #   'SecondKey' => 2
                   # }
hash = { first_key: 1, 'second_key' => 2 }
options = { uppercase_first_letter: false }
hash.camelize_keys(options) # returns {
                            #   firstKey: 1,
                            #   'secondKey' => 2
                            # }

Parameters:

  • options (::Hash) (defaults to: {}) —

    options of camelization

Options Hash (options):

  • uppercase_first_letter: (::Boolean) —

    flag defining the type of CamelCase

Returns:

  • (::Hash) —

    new hash with changed keys

  Hash::KeyChanger.new(self).camelize_keys(options)
end

#lower_camelize_keys(options = {}) ⇒ ::Hash

Camelize all keys in the hash as ‘key.camelize(:lower)

Examples:

hash = { first_key: 1, 'second_key' => 2 }
hash.lower_camelize_keys # {
                         #   firstKey: 1,
                         #   'secondKey' => 2
                         # }

Returns:

  • (::Hash) —

    the resulting hash

def lower_camelize_keys(options = {})
  dup.lower_camelize_keys!(options)
end

#lower_camelize_keys!(options = {}) ⇒ ::Hash

Camelize all keys in the hash

Examples:

hash = { first_key: 1, 'second_key' => 2 }
hash.lower_camelize_keys # {
                         #   firstKey: 1,
                         #   'secondKey' => 2
                         # }

Returns:

  • (::Hash) —

    self after changing the keys
