feat(admin): import a problem from JSON in the new-problem form - #129
Merged
Conversation
The admin New Problem page now has an "Import from JSON" panel: paste a problem in the challenge JSON schema (the same shape as challenges/*.json) or upload a .json file, and it fills the whole form — title/slug/date/difficulty/tags/limits, the Markdown prose, samples, hidden tests, and checker. - Parses defensively (bad JSON or a missing title/date/statement/samples/tests is surfaced inline), derives the slug from the title when absent, and falls back for an unknown difficulty/checker. The server's AdminChallengeSchema still validates fully on save, so the import only pre-fills — the admin reviews before creating. - Create mode only (edit keeps the slug locked). Purely client-side; no new endpoint. tsc / eslint / next build green; the JSON -> form mapping verified against a sample.

What
The admin New Problem page gains an "Import from JSON" panel: paste a problem in the challenge JSON schema (same shape as
challenges/*.json) — or upload a.jsonfile — and it fills the entire form: title / slug / date / difficulty / tags / limits, the Markdown statement / input / output / constraints, samples, hidden tests, and checker.Behaviour
title/date/statement/samples/tests, is surfaced inline before anything loads.Unrated/tokenfor an unknown difficulty / checker.AdminChallengeSchemastill runs full validation on save. So a slightly-off import surfaces as the usual field-level errors, not a bad row.Verified
tsc/eslint/next buildgreen; the JSON → form mapping checked against a sample (slug derivation, tag join, samples/tests, float checker + epsilon, invalid-difficulty fallback).Refs #82
