====== Option +unconverted_fields+
|
||
|
|
|
||
|
|
Specifies the boolean that determines whether unconverted field values are to be available.
|
||
|
|
|
||
|
|
Default value:
|
||
|
|
CSV::DEFAULT_OPTIONS.fetch(:unconverted_fields) # => nil
|
||
|
|
|
||
|
|
The unconverted field values are those found in the source data,
|
||
|
|
prior to any conversions performed via option +converters+.
|
||
|
|
|
||
|
|
When option +unconverted_fields+ is +true+,
|
||
|
|
each returned row (\Array or \CSV::Row) has an added method,
|
||
|
|
+unconverted_fields+, that returns the unconverted field values:
|
||
|
|
str = <<-EOT
|
||
|
|
foo,0
|
||
|
|
bar,1
|
||
|
|
baz,2
|
||
|
|
EOT
|
||
|
|
# Without unconverted_fields
|
||
|
|
csv = CSV.parse(str, converters: :integer)
|
||
|
|
csv # => [["foo", 0], ["bar", 1], ["baz", 2]]
|
||
|
|
csv.first.respond_to?(:unconverted_fields) # => false
|
||
|
|
# With unconverted_fields
|
||
|
|
csv = CSV.parse(str, converters: :integer, unconverted_fields: true)
|
||
|
|
csv # => [["foo", 0], ["bar", 1], ["baz", 2]]
|
||
|
|
csv.first.respond_to?(:unconverted_fields) # => true
|
||
|
|
csv.first.unconverted_fields # => ["foo", "0"]
|
