New description: When you clean a `RangeField` and pass it in `('', '')`, or `(None, None)`, it falls through to the `MultiValueField` handling, which, when all values are empty, [https://github.com/django/django/blob/a6b5321ce997b899e540bb427cca98cb2b93a106/django/forms/fields.py#L992 treats the cleaned value as empty]. Thus, `FloatRangeField().clean([None, None])` returns `None`, when it really should return `FloatRange(None, None)`. There is a very large difference between these. -- Comment: I'm not sure -- could you elaborate on the use case? How can you submit a `[None, None]` value in an HTML form (or are you also advocating transforming `['', '']` to `Range(None, None)`)? -- Ticket URL: <https://code.djangoproject.com/ticket/28310#comment:1> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
