Writing Data (Go)

Overview

The Prisma client is based on the operations defined in the GraphQL schema of your Prisma API. For writing data, it basically mirrors the GraphQL mutations of your Prisma service.

For this page, we'll assume your Prisma API is based on the following datamodel:

type Link {
  id: ID! @unique
  createdAt: DateTime!
  description: String!
  url: String!
  postedBy: User
  votes: [Vote!]!
}

type User {
  id: ID! @unique
  name: String!
  email: String! @unique
  password: String!
  links: [Link!]!
  votes: [Vote!]!
}

type Vote {
  id: ID! @unique
  link: Link!
  user: User!
}

Creating objects

When creating new records in the database, the create-method takes one input object which wraps all the scalar fields of the record to be created. It also provides a way to create relational data for the model, this can be supplied using nested object writes.

Each method call returns an object that contains all the scalar fields of the model that was just created.

Examples

Create a new user:

name := "Alice",
email := "alice@prisma.io",
password := "IlikeTurtles"
newUser, err := db.CreateUser(&prisma.UserCreateInput{
  Name: &name,
  Email: &email,
  Password: &password,
}).Exec()
