here is my all model example i trying to find from many to many relationship. the code exucuted but no data found.
model UsersHavePermission{
user User #relation(fields: [userId],references: [id])
userId Int
permission Permission #relation(fields: [permissionId],references: [id])
permissionId Int
create Boolean
update Boolean
delete Boolean
##id([userId,permissionId])
model Permission{
id Int #id #default(autoincrement())
name String #unique
isActive Boolean
user UsersHavePermission[]
}
model User{
id Int #id #default(autoincrement())
email String #unique
password String
is_active Boolean
roll Roll #relation(fields: [rollId],references: [id])
rollId Int
profile Profile?
permissions UsersHavePermission[]
degees DegreeBasedJobForUser[]
categories CategoriesBasedJobForUser[]
}
const checkCreate = await prisma.usersHavePermission.findFirst({
where: {
userId_permissionId: {
userId: parseInt(req.body.userId),
permissionId: parseInt(req.body.permissionId),
},
},
});
res.send(checkCreate);

I have a one to many relationship, and I need to filter the relationship values, I need to bring all the records that contain all the values of the array/
example: const attributes = ["Car", "Bike", "Truck"]
prisma.car.findMany({
where: {
attribute: {
typeCar: {
every: {
value: { hasSome: attributes },
},
},
},
},
});
This search works only if all attributes exist, if any attribute does not exist, nothing is returned
I need it to return the record, even if typeCar does not contain all records.
How could I do that with the prisma?
My model
model Car {
id String #id
name String
status String
description String
thumbnailUrl String?
groupId String?
categoryName String
attribute Attribute[]
images CarImage[]
createdAt DateTime #default(now())
updatedAt DateTime? #updatedAt
##map("car")
}
model Attribute {
id String #id
typeCar String[]
car Car? #relation(fields: [carId], references: [id])
carId String?
createdAt DateTime #default(now())
updatedAt DateTime? #updatedAt
##map("attributeProductValue")
}
One solution I found was to add a new field in the car table. Saving the values of the typeCar
model Car {
id String #id
name String
status String
description String
thumbnailUrl String?
groupId String?
categoryName String
attribute Attribute[]
images CarImage[]
typeCarValues String[]
createdAt DateTime #default(now())
updatedAt DateTime? #updatedAt
##map("car")
}
So I can filter without going through the relationship, and the hasEvery option works.
example: const attributes = ["Car", "Bike", "Truck"]
prisma.car.findMany({
where: {
typeCarValues: {
hasEvery: attributes,
},
},
})
The problem was in filtering the relationship in attributes using every and then hasEvery, to return the value all attributes of typeCar need to be informed and exist, if any of them is not informed, it does not return.
I want to seed a default value in the database...These values include a role and a user.
How can I take the role value after seed and add it to the next seed which is adding the user?Is this possible or not?
Seed Role :
modelBuilder.Entity<Role>().HasData(
new Role { RoleId = Guid.NewGuid(), RoleName = "User" },
new Role { RoleId = Guid.NewGuid(), RoleName = "Admin"}
);
Seed User :
modelBuilder.Entity<User>().HasData(
new User { UserId = 1,RoleId = ?}
);
Actually I want to get the Admin role ID and add it to the RoleId field in the User table?
Using Prisma v 3.8.1
My User Model is
model User {
id Int #id #default(autoincrement())
createdAt DateTime? #default(now())
email String #unique
name String
password String
accessToken String?
accessTokenCreatedAt DateTime? #default(now())
address String?
city String?
state String?
postalCode String?
phoneNumber Int?
igUserId String?
role Role #relation(fields: [roleId], references: [id])
roleId Int
organization Organization? #relation(fields: [organizationId], references: [id])
organizationId Int?
orders Order[]
}
Generated type is
type User = {
id: number;
createdAt: Date | null;
email: string;
name: string;
password: string;
accessToken: string | null;
accessTokenCreatedAt: Date | null;
address: string | null;
city: string | null;
state: string | null;
postalCode: string | null;
phoneNumber: number | null;
igUserId: string | null;
roleId: number;
organizationId: number | null;
}
There are no optional fields in this type as described in the model, not even for the autogenerated id field. So while using this type in my code, I keep getting this error
Type '{ name: any; email: any; password: string; roleId: number; }' is missing the following properties from type 'User': id, createdAt, accessToken, accessTokenCreatedAt, and 7 more.
Expected behaviour: Optional fields should be marked optional ? in the generated typescript Types so that its easy in the code to only set the required fields and pass it to .create() method
This type is not intended to use with create or similar methods. It's return type of find* methods and such. It's supposed to match DB table and table does not have undefined or optional rows, only nullable or not.
If you look carefully you can find other types, for example, UserCreateArgs with data property which will be used for create method. And that type has optional fields exactly how you want it to be.
What I don't understand is where you got this error from? Have you tried to use the types for your own wrappers?
I have a lot of trouble figuring out the 1 to 1 and 1 to many relation i made this schema then I have my graphql derived from that

Basically a user will have boxes that they own (
The boxes has a Game Type and contains a parent Set which
Has it own set code and contain set children (array)
The game type it self has only name and shortcode
My main issue is that when I try to create a set with the resolver code
the graphql
mutation {
createBox (input:{box_number:"001", secondary_number:"A", game:{name:"yu"}, set:"Crucibile of War Unlimit"}) {
box_number
set
game
id
}
}
the resolver
createBox: async (_: any, { input }: any, context: Context) => {
const find = await context.prisma.games.findFirst({
where: {name: {contains:input.game[0].name,
mode:"insensitive"}}
}
);
console.log(find);
console.log(input.set);
return await context.prisma.box.create({
data: {
box_number: input.box_number,
box_second_number: input.secondary_number,
gameid: find?.id,
set: {connect: {
name: input.set
},
},
},
});
},
I get
" Foreign key constraint failed on the field: `Box_set_fkey (index)`",
" at cb
I'm really confused on how to make it work
In this case, set directly expects the relation so you don't need connect here. This should work:
const find = await prisma.games.findFirst({
where: { name: { contains: input.game[0].name } },
})
await prisma.box.create({
data: {
box_number: input.box_number,
box_second_number: input.secondary_number,
gameid: find?.id,
set: input.set,
},
})
I am creating a schema in prisma with the model User and Guild.
User can have one guild or none
Guild can have multiple User
Now I want to add an additional field of the role a user have in the guild.
What would be the best to achieve this?
I could add them to the user but then I have to manage it in the code that all are null or not null.
enum GuildRole {
MEMBER
CO_LEADER
LEADER
}
model Guild {
id Int #id #default(autoincrement())
name String
users User[]
}
model User {
id Int #id #default(autoincrement())
username String? #unique
guild Guild? #relation(fields: [guildId], references: [id])
guildId Int?
guildRole GuildRole?
}
You can do it as following when adding an existing user to a guild.
import { PrismaClient, GuildRole } from '#prisma/client'
const prisma = new PrismaClient()
// add user to guild
const addAnExistingUserToAGuild = async (userId: number, guildId: number, guildRole: GuildRole) => {
return await prisma.user?.create({
data: {
guildId: guildId,
userId: userId,
guildRole: guildRole,
},
})
}
The modelling will completely depend on your personal/company preference/style, I've modelled your schema like this :
enum GuildRole {
MEMBER
CO_LEADER
LEADER
}
model User {
userId Int #id #default(autoincrement())
username String? #unique
guild Guild? #relation(fields: [guildId], references: [guildId])
guildId Int?
guildRole GuildRole?
}
model Guild {
guildId Int #id #default(autoincrement())
name String
users User[]
}
