CSV::Row#dig

row.dig(index_or_header, *identifiers) → object

# File tmp/rubies/ruby-3.1.3/lib/csv/row.rb, line 715
def dig(index_or_header, *indexes)
  value = field(index_or_header)
  if value.nil?
    nil
  elsif indexes.empty?
    value
  else
    unless value.respond_to?(:dig)
      raise TypeError, "#{value.class} does not have \#dig method"
    end
    value.dig(*indexes)
  end
end

Finds and returns the object in nested object that is specified by index_or_header and specifiers.

The nested objects may be instances of various classes. See Dig Methods.

Examples:

Example

source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
table = CSV.parse(source, headers: true)
row = table[0]
row.dig(1) # => "0"
row.dig('Value') # => "0"
row.dig(5) # => nil
