I couldn't find any relevant info on Prisma docs, nor on SO on this question.
My relevant schema looks like this:
model User {
id Int #default(autoincrement()) #id
createdAt DateTime #default(now())
updatedAt DateTime #updatedAt
firstName String?
lastName String?
email String #unique
hashedPassword String?
role String #default("user")
sessions Session[]
profile Profile?
}
model Profile {
id Int #default(autoincrement()) #id
aboutMe String?
location String?
profession String?
user User #relation(fields:[userId], references: [id])
userId Int
}
I want to update multiple columns in both tables however, have been unable to get the mutation to work in Prisma. So, this is what my mutation looks like at the moment:
...
const {aboutMe, location, profession, firstName, lastName } = inputs;
const profile = await db.user.update({
where: { id: ctx.session!.userId },
data: {
profile: {
update: {
aboutMe,
location,
profession,
},
},
},
});
const user = await db.user.update({
where: { id: ctx.session!.userId },
data: {
firstName,
lastName,
},
});
...
As you can see, I have two mutations, is it possible the update multiple tables with a single mutation?
Thank you.
This should work:
const profile = await db.user.update({
where: { id: u.id },
data: {
firstName: 'name',
lastName: 'name',
profile: {
update: {
aboutMe: 'aboutMe',
location: 'aboutMe',
profession: 'aboutMe',
},
},
},
include: { profile: true },
})

i'm currently working on a twitter clone with express / prisma / postgreSQL for my backend.
I'm struggling to imitate twitter's feed.
Here's my current prisma Schema
model User {
id String #id #default(cuid())
email String #unique
username String #unique
profilename String?
password String
bio String?
image String?
createdAt DateTime #default(now())
isAdmin Boolean #default(false)
tweets Tweet[]
retweets Retweet[]
likes Like[]
followers Follows[] #relation("follower")
following Follows[] #relation("following")
}
model Follows {
follower User #relation("following", fields: [followerId], references: [id])
followerId String
following User #relation("follower", fields: [followingId], references: [id])
followingId String
createdAt DateTime #default(now())
##id([followerId, followingId])
}
model Tweet {
id String #id #default(cuid())
content String
createdAt DateTime #default(now())
deleted Boolean #default(false)
media String[]
author User #relation(fields: [authorId], references: [id], onDelete: Cascade)
authorId String
originalTweet Tweet? #relation("replies", fields: [originalTweetId], references: [id], onDelete: Cascade)
originalTweetId String?
responses Tweet[] #relation("replies")
likes Like[]
retweets Retweet[]
hashtags Hashtag[]
}
model Hashtag {
id String #id #default(cuid())
name String #unique
createdAt DateTime #default(now())
tweets Tweet[]
}
model Retweet {
id String #id #default(cuid())
tweet Tweet #relation(fields: [tweetId], references: [id], onDelete: Cascade)
tweetId String
user User #relation(fields: [userId], references: [id], onDelete: Cascade)
userId String
createdAt DateTime #default(now())
}
model Like {
id String #id #default(cuid())
tweet Tweet #relation(fields: [tweetId], references: [id], onDelete: Cascade)
tweetId String
user User #relation(fields: [userId], references: [id], onDelete: Cascade)
userId String
createdAt DateTime #default(now())
}
and my current function to get user feed
exports.getUserFeed = async (userId, options = {}) => {
try {
const user = await prisma.user.findUnique({
where: { id: userId },
include: { following: true },
})
if (user.following.length === 0) {
return prisma.tweet.findMany({
orderBy: {
createdAt: "desc",
},
...options,
})
}
return prisma.tweet.findMany({
where: {
OR: [
{
author: {
followers: {
some: {
followerId: userId,
},
},
},
},
{
likes: {
some: {
user: {
followers: {
some: {
followerId: userId,
},
},
},
},
},
},
{
retweets: {
some: {
user: {
followers: {
some: {
followerId: userId,
},
},
},
},
},
},
],
},
orderBy: {
createdAt: "desc",
},
...options,
})
} catch (err) {
throw new Error(err)
}
}
With this i get tweets posted by user i follow, liked by user i follow and retweeted by user i follow but order by tweet's created at not by the "event" created at.
To solve this i thought about creating a new model called Event or Status with optionnal feed like:
isRetweet ?
isLike ?
etc
and then retrieve this instead of tweet model.
But it seems messy and complex for no reason.
Is there a way to actually define a better schema or do a better query ?
Thanks a lot.
Hi I have three models
model User {
user_id Int #id #default(autoincrement())
email String #unique
name String?
User_Account User_Account[]
}
model Account {
account_id Int #id #default (autoincrement()) #unique
email String
bank String
createdAt DateTime #default(now())
User_Account User_Account[]
}
model User_Account {
id Int #id #default(autoincrement())
accountId Int
userId Int
User User #relation(fields: [userId], references: [user_id])
Account Account #relation(fields: [accountId], references: [account_id])
}
I am trying to seed my db like this
const data = [
{
id: 1,
email: 'pranit1#mf.com',
name: 'Pranit1',
bank: 'VCB',
ids: [1,1]
},
{
id: 2,
email: 'pranit1#mf.com',
name: 'Pranit1',
bank: 'ACB',
ids: [1,2]
},
{
id: 3,
email: 'pranit3#mf.com',
name: 'Pranit3',
bank: 'VCB',
ids: [2,3]
}
]
const users = await prisma.$transaction(
data.map(user =>
prisma.user.upsert({
where: { email: user.email },
update: {},
create: { name: user.name,
email:user.email },
})
)
);
const accounts = await prisma.$transaction(
data.map(account =>
prisma.account.upsert({
where: { account_id: account.id },
update: {},
create: { bank: account.bank ,
email :account.email },
})
)
);
const user_accounts = await prisma.$transaction(
data.map(uacc =>{
console.log(uacc);
return prisma.user_Account.upsert({
where: { id: uacc.id },
update: {id: uacc.id},
create:{
userId: uacc.ids[0],
accountId: uacc.ids[1] },
})}
)
);
However I am getting an
Unique constraint failed on the constraint: User_Account_userId_key
The data in prisma studio is generated as shown in the image
I am simply trying to create users and accounts and a user can be associated with multiple accounts. Their relation is shown in the User_Account table. I cant see why I am getting a unique constraint error when I dont have the #unique tag on userId
I was unable to reproduce the error on my side.
But I suspect you already had records on the DB and they conflict with the ids of your seeder.
Also, there are some improvements you could make on your schema for being simpler.
Since you don't have any extra details on the many-to-many relation you can get rid of the User_Account model and let Prisma handle it for you.
On the seeder, you can take advantage of the nesting features of Prisma so that you don't have to manually link the records. That way, you don't have to worry about ids.
schema.prisma suggestion
model User {
id Int #id #default(autoincrement())
email String #unique
name String?
accounts Account[]
}
model Account {
id Int #id #unique #default(autoincrement())
email String
bank String
users User[]
createdAt DateTime #default(now())
}
seed.js suggestion
const { PrismaClient } = require("#prisma/client");
const prisma = new PrismaClient();
async function main() {
const usersData = [
{
email: "pranit1#mf.com",
name: "Pranit1",
banks: ["VCB", "ACB"],
},
{
email: "pranit3#mf.com",
name: "Pranit3",
banks: ["VCB"],
},
];
const users = await prisma.$transaction(
usersData.map((user) =>
prisma.user.upsert({
where: { email: user.email },
update: {},
create: {
name: user.name,
email: user.email,
accounts: {
create: user.banks.map((bank) => ({
email: user.email,
bank,
})),
},
},
})
)
);
}
main()
.catch((e) => {
console.error(e);
process.exit(1);
})
.finally(async () => {
await prisma.$disconnect();
});
I want to find only one post matching by post id and prodCode
below is my query code. It doesn't work.
If i change findUnique to findFirst. it works.
const post = await client.post.findUnique({
where: {
AND: [
{ id: postId },
{
product: {
prodCode,
},
},
],
},
});
prisma model
model Product {
id Int #id #default(autoincrement())
prodName String
prodCode String #unique
posts Post[]
holdings Holding[]
proposes Propose[]
}
model Post {
id Int #id #default(autoincrement())
user User #relation(fields: [userId], references: [id])
userId Int
product Product #relation(fields: [productId], references: [id])
productId Int
title String
content String
createdAt DateTime #default(now())
}
Since Post.id is unique, you don't need to filter by prodCode as well. You could just query the post record with the needed id and then check if the connected product has the right prodCode.
I would just do this:
const post = await prisma.post.findUnique({
where: {
id: postId
},
include: {
product: true
}
});
if (post.product.prodCode === prodCode) {
// No result for desired query
} else {
// "post" variable contains result of desired query
}
I am wondering if it is possible to pass multiple IDs to a useQuery for apollo hook. Or run a single query per ID, and if so how would I go about doing so.
I have the following query
const DECOR_SHEET = gql`
query GetDecorSheet($id: ID!) {
findDecorSheetByID(id:$id){
refIdArray
sheetName
_id
}
}
`;
and the following useQuery hook
const { loading, error, data: sheetData } = useQuery(DECOR_SHEET, {
variables: { id: id },
context: {
headers: {
authorization: cookieBearer,
},
},
});
I have the following IDs 293164663883956749, 293526016787218952 and I would like to return into one object in order to render into a component.
I am using Fauna DB and this is the input graphQL schema

There is an option to query with Fauna's FQL which may have a way of querying multiple IDs I will have to look into that, but would prefer to do this in graphQL with apollo if possible.
Thanks ahead of time
Thanks to support from FaunaDB
The following query and UDF does the trick
Query
type Query {
getMultipleDecors(DecorId: [ID!]): [Decor]
#resolver(name: "get_multiple_decors")
}
udf named get_multiple_decors
Query(
Lambda(
["input"],
Let(
{
data: Map(
Var("input"),
Lambda("x", Get(Ref(Collection("Decor"), Var("x"))))
)
},
Var("data")
)
)
)
If it's always exactly two ids, you can fetch both objects in a single query easily using field aliases:
const DECOR_SHEET = gql`
query GetDecorSheet($firstId: ID!, $secondId: ID!) {
firstDecorSheet: findDecorSheetByID(id: $firstId) {
refIdArray
sheetName
_id
}
secondDecorSheet: findDecorSheetByID(id: $secondId) {
refIdArray
sheetName
_id
}
}
`;
My mongo db data:
{
username: 'gemmi',
age: 14,
id: 'xsxsxsxsxss'
}
type Query:
{
type Query {
getUser(id: String, username: String): User
}
}
resolver
getUser(root, args) {
return Meteor.users.findOne({ _id: args.id, username: args.username });
},
My question is how I can get user by given variable?
So it should return user when i type:
getUser(id: "xsxsxsxsxss", username:"gemmi") { username _id }
and also when I type:
getUser(username:"gemmi") { username _id }
You could replace the id with _id in the Query
{
type Query {
getUser(_id: String, username: String): User
}
}
And then you could simply use the args parameter to perform findOne call
getUser(root, args) {
return Meteor.users.findOne(args);
}
The args object depends on how you performed the query call. You should remember about replacing id with _id in your calls. In the first case, when you did getUser(_id: "xsxsxsxsxss", username:"gemmi"), then args object is { _id: 'xsxsxsxsxss', username: 'gemmi' }, however in second case, when you want to use getUser(username:"gemmi"), the args object is { username: 'gemmi' }, so in both cases you can use it as a query lookup in the findOne method call.
I suggest you add a input type for your query. And let meteor search for the respective user.
It could look like this:
Query:
`
type User {
id: ID!
username: String!
}
input UserInput {
id: ID
username: String
}
type Query {
getUser(user: UserInput!): User!
}
`
Resolver:
...
getUser(root, { user }) {
return Meteor.users.findOne(user);
}
...
