One of these 8 values:
| Value | Written |
|---|---|
BloodType.a_positive |
A+ |
BloodType.a_negative |
A- |
BloodType.ab_positive |
AB+ |
BloodType.ab_negative |
AB- |
BloodType.b_positive |
B+ |
BloodType.b_negative |
B- |
BloodType.o_positive |
O+ |
BloodType.o_negative |

Example
BloodType.o_negativetext.parse(raw, as: BloodType) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as O pos, 0+ or O.
Good to know
==tells you whether two are the same.<andlist.sort_bydon't take it.- A field that holds one counts as personal data (
health), so you don't mark it yourself.
In JSON
A string, in a request, a response or json.write:
"AB+""O-"
Details
Text form, storage, how it is shown, and operations
BloodType is in the group Health, and has been in Jadpo since 0.1.0.
Text form
text.from writes one standard text form, the same form text.parse reads back: AB+ and O-.
How it is stored
It is stored in one column named for the field, of type text. O- is stored as 'O-'.
How it is shown to people
text.format(value, locale:) shows it to people in their locale.
With locale: Locale.en_gb:
| Value | Shown |
|---|---|
AB+ |
AB+ |
O- |
O- |
Operations
It also takes text.parse, text.from, text.format, json.read, json.write and ==. How every standard type behaves says how they work.
