'use server' を付ける。FormData / 引数を必ず Zod で検証してから処理する。revalidatePath / revalidateTag でキャッシュを無効化する。useActionState でローディング・エラーを扱う。'use server' + 入力 Zod 検証 + 認可チェックを必ずセットにする。{ ok: true } | { ok: false, error })にする。// app/users/actions.ts
'use server';
import { z } from 'zod';
import { revalidatePath } from 'next/cache';
import { requireUser } from '@/lib/auth';
import { UserModel } from '@/models/user';
const UpdateName = z.object({ id: z.string().length(24), name: z.string().min(1).max(80) });
export async function updateName(_: unknown, formData: FormData) {
const session = await requireUser();
const parsed = UpdateName.safeParse(Object.fromEntries(formData));
if (!parsed.success) return { ok: false as const, error: '入力が不正です' };
const { id, name } = parsed.data;
if (session.userId !== id) return { ok: false as const, error: '権限がありません' };
await UserModel.updateOne({ _id: id }, { $set: { name } });
revalidatePath(`/users/${id}`);
return { ok: true as const };
}
Object.fromEntries(formData) をそのまま DB へ(検証なし)。revalidatePath('/') で広く無効化し、無関係なページまで再生成する。No reviews yet. Tell others what you thought.
