Prisma 2 query to return records only that are associated with ALL of the provided tag IDs - react-apollo

Question

I have tables Principles and Tags. And there is a many-to-many relation between them (joined implicitly).
Without using prisma.raw, how can I run the following query?
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})
How can I update this Prisma 2 query such that the principles returned are only principles that are associated with ALL of the provided tagIds?
export const principles = ({ tagIds }) => {
const payload = {
where: {
//TODO filter based on tagIds
},
}
return db.principle.findMany(payload)
}
The docs mention contains and in and every, but I can't find examples of what I'm trying to do.
I'm using RedwoodJs, Prisma 2, Apollo, GraphQL.

Answer 1

It doesn't look like you are using prisma 2. Prisma 2 uses models (not types) and has arrays classified like Principles[] vs [Principles]. Maybe Redwood does the conversion(Never used it).
I created your model in Prisma 2 and used the following command to get a single principle that has the two tags associated with it. Keep in mind the IDs in there are from my test dataset. Hopefully, you can modify this to your code. If not, please create a sandbox/playground with minimal code for us to test.
export const principles = async ({ searchQuery, tagIds }) => {
const payload = {
where: {
OR: [
{ title: { contains: searchQuery } },
{ description: { contains: searchQuery } },
],
userId: userIdFromSession,
},
}
if (tagIds.length) {
const whereAnd = []
tagIds.forEach((tagId) => {
whereAnd.push({
tags: { some: { id: tagId } },
})
})
payload.where.AND = whereAnd
}
const result = await db.principle.findMany(payload)
return result
}

Answer 2

You could try something like this
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)
}
That should do the trick!

Answer 3

I had to resort to using AND for something similar - hope this helps!
const tagIds = [9,6];
where: {
// ...
AND: tagIds.map(tagId => ({
tags: {
some: {
id: {
equals: tagId,
},
},
},
})),
}
