Prisma 2 - Unkown arg 'where' in select.fruit.where for type UserFruit. Did you mean 'select'? Available args - json

Question

Trying to query in prisma and filter results from a related object but get the error:
Unknown arg 'where' in select.fruit.where for type UserFruit. Did you
mean 'select'? Available args fruit{}
async findShops(req) {
const userId = parseInt(req.params.id);
const shop = await prisma.shop.findMany({
select: {
id: true,
name: true,
logo: true,
fruit:{
select:{
id:true,
userId:true,
fruitNumber:true,
created: true,
updated: true,
},
where: {
userId: userId
}
}
}
})
return shop;
};
example payload expected:
[
{ id: 1001, name: 'test1', logo: 'log.png', fruit: null },
{ id: 1002, name: 'test2', logo: 'log2.jpg', fruit: null },
{ id: 1003, name: 'test3', logo: 'log3.jpg', fruit: null },
{
id: 1005,
name: 'test4',
logo: 'log4.png',
fruit: {
id: '62450ee5-e75d-4a67-8d79-120d11ddf508',
userId: 111,
fruitNumber: '123456',
created: 2022-07-01T06:39:52.924Z,
updated: 2022-07-01T06:39:52.936Z
}
},
{
id: 1004,
name: 'test5',
logo: 'log5.jpg',
fruit: {
id: '20e9af37-2e6f-4070-8475-c5a914f311dc',
userId: 111,
fruitNumber: '123878',
created: 2022-07-01T07:21:27.898Z,
updated: 2022-07-01T07:21:27.901Z
}
}
]
I can easily achieve the expected output by not having the "where" but I need it because the fruit object can contain more than 1 object so I need to filter by userId e.g.
fruit: {
id: '62450ee5-e75d-4a67-8d79-120d11ddf508',
userId: 111,
fruitNumber: '123456',
created: 2022-07-01T06:39:52.924Z,
updated: 2022-07-01T06:39:52.936Z
},
{
id: '62450ee5-e75d-4a67-8d79-120d11ddf508',
userId: 999,
fruitNumber: '123456',
created: 2022-07-01T06:39:52.924Z,
updated: 2022-07-01T06:39:52.936Z
}
For the fruit object I need nulls and anything that matches the userId and based on design it should only ever be 1 record for each shop for the specific user.
At somepoint my code seemed to work but after I did a prisma generate it stopped working. Is there another way I can achieve the same result or is there someway to fix this?
Note:version info below.
model UserFruit {
id String #id #default(uuid())
fruitNumber String #map("fruit_number")
shopId Int #unique #map("shop_id")
userId Int #map("user_id")
created DateTime #default(now())
updated DateTime #updatedAt
fruit Fruit #relation(fields: [fruitId], references: [id])
##unique([userId, fruitId], name: "userFruit")
##map("user_Fruit")
}
model Shop {
id Int #id #default(autoincrement())
name String #unique
logo String
created DateTime #default(now())
updated DateTime #updatedAt
fruit UserFruit?
##map("Shop")
}
model User {
id Int #id #default(autoincrement())
created DateTime #default(now())
updated DateTime #updatedAt
uid String #unique
email String #unique
phone String #unique
firstName String #map("first_name")
lastName String #map("last_name")
dob DateTime?
gender String?
roleId Int #default(1) #map("role_id")
role Role #relation(fields: [roleId], references: [id])
##map("user")
}

Answer 1

Why not do a nested where at the top level to only search for shops whose fruit has the userId you need, rather than doing a nested select? It should make your query simpler and also solve your problem.
const userId = parseInt(req.params.id);
const shop = await prisma.shop.findMany({
select: {
id: true,
name: true,
logo: true,
fruit: {
select: {
id: true,
userId: true,
fruitNumber: true,
created: true,
updated: true,
},
// Removed the nested "where" from here
},
},
where: {
// One of the following conditions must be true
OR: [
// Return shops who have a connected fruit AND
// the fruit's "userId" attribute equals the variable "userID"
{
fruit: {
is: {
userId: userId,
// Can also simplify this to the below line if you want
// userId
},
},
},
// Return shops who do not have a connected fruit
// this will be true if "fruitId" is null
// could also write this as {fruit: {is: {}}}
{
fruitId: {
equals: null,
},
},
],
},
});
This query should output an array of shops where the connected fruit model's userId property equals your userId variable.
