テーブルの原則とタグがあります。そして、それらの間には多対多の関係があります( 暗黙的に結合 )。
使わずに prisma.raw
、次のクエリを実行するにはどうすればよいですか?
SELECT p.id, p.title, p.description, p.createdAt, p.modifiedAt
FROM principle p
WHERE EXISTS (SELECT NULL
FROM _PrincipleToTag pt
WHERE pt.B IN (${tagIds.join(',')})
AND pt.A = p.id
GROUP BY pt.A
HAVING COUNT(DISTINCT pt.B) = ${tagIds.length})
このPrisma 2クエリを更新して、返される原則が提供されたすべてのtagIdに関連付けられている原則のみになるようにするにはどうすればよいですか?
export const principles = ({ tagIds }) => {
const payload = {
where: {
//TODO filter based on tagIds
},
}
return db.principle.findMany(payload)
}

について言及していますが、私がやろうとしていることの例が見つかりません。
RedwoodJs、Prisma 2、Apollo、GraphQLを使用しています。

あなたはこのようなものを試すことができます
export const principles = ({ searchQuery, tagIds }) => {
const payload = {
where: {
OR: [
{ title: { contains: searchQuery } },
{ description: { contains: searchQuery } },
],
// using the `in` operator like this
tagId: { in: tagIds },
userId: userIdFromSession,
},
}
console.log('db.principle.findMany(payload)', payload)
return db.principle.findMany(payload)
}
これでうまくいくはずです!
