Häufige Annahme

The CSV :numeric and :integer converters parse numeric string values using base-10 decimal representation.

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• CSV.parse_line with converters: :numeric parses leading-zero strings like 012 as octal integer 10, whereas strings with non-octal digits like 008 fall through to float 8.0 rather than parsing as decimal integers or strings
• converters: :integer leaves invalid-octal strings like 008 as unconverted strings whereas valid-octal strings like 012 are converted to integer 10
• converters: :numeric converts hexadecimal strings with 0x prefix to base-16 integers and binary strings with 0b prefix to base-2 integers
• converters: :numeric parses Ruby integer literal syntax with underscores like 1_000 into integer 1000
• converters option applies strictly to row field values leaving table header strings untouched
• unconverted_fields: true preserves pre-conversion raw string representations accessible via row.unconverted_fields
