Lo que suele suponerse
Passing converters: :numeric parses numeric strings with leading zeros as decimal numbers or preserves them consistently as strings.
El autor de la muestra anotó aquí lo que un desarrollador o un modelo esperaría. El contrato de abajo es lo que realmente se ejecutó.
Contrato
- CSV.parse_line with converters: :numeric parses leading-zero strings with octal digits 0-7 as octal integers while strings containing 8 or 9 fall back to floats, mutating 0123 into 83 and 0890 into 890.0 across a round trip
- assert CSV.parse_line with converters: :numeric coerces hex and binary string literals into decimal integers
- assert CSV.generate_line with a single nil element emits an empty line that CSV.parse_line reads as an empty array of length zero
- assert CSV.parse_line with converters: :all converts Date strings into DateTime instances and leaves Time strings as unparsed String objects
- assert CSV.parse_line with unconverted_fields: true retains the original string representations on the unconverted_fields attribute
