A Go templating fix for date inputs that came up blank.
Kurze Antwort
In IOTA SDK, date fields on edit pages didn't show the value stored in the database. The date field only rendered its default, and the datetime-local field passed a raw time.Time as an attribute value. The fix uses the stored value when present and formats it in the layout HTML expects. It was merged as PR #1031 and closed issue #340.
The problem
Issue #340, filed by a maintainer, reported that date fields rendered by the CRUD builder on edit pages "are missing the value that is set in DB", and that the same issue appeared on other pages.
The fix
const dateTimeLocalLayout = "2006-01-02T15:04"
...
if val := mapping.Or(f.value, f.defaultVal); !val.IsZero() {
attrs["value"] = val.Format(time.DateOnly)
}
...
if val := mapping.Or(f.value, f.defaultVal); !val.IsZero() {
attrs["value"] = val.Format(dateTimeLocalLayout)
}Zero values now omit the value attribute entirely, and stored values take precedence over defaults.

How the review went
An automated reviewer asked for two things: table-driven tests, per the repo's guidelines, and cases covering stored values through WithValue, including precedence over defaults. The follow-up commit addressed both, and the final 112-line test file covers defaults, stored values, precedence, formatting and empty fields. The maintainer who filed the issue merged the PR. The public review comments recorded in the supplied research are automated; this is not evidence of a separate human review.

Das Ziel
HTML date inputs are strict about format. A fix that encodes the exact layout once, with tests around it, keeps edit pages honest about what is stored.
