Mutation with list of strings as argument in Prisma + GraphQL - list

Question

I am trying to make a mutation but I am getting an error with the arguments.
In schema.graphql I have the following:
type User {
id: ID!
name: String!
email: String!
age: Int!
height: Float!
weight: Float!
goals: [String!]!
history: [Routine!]!
}
type Mutation {
signup(email: String!, password: String!, name: String!, age: Int!, height: Float!, weight: Float!, goals: [String!]!): AuthPayload
}
In schema.prisma:
model User {
id Int #id #default(autoincrement())
name String
email String #unique
password String
age Int
weight Float
height Float
goals String[]
history Routine[]
}
Then my mutation resolver is the following:
async function signup(parent, args, context, info) {
// 1
const password = await bcrypt.hash(args.password, 10)
// 2
const user = await context.prisma.user.create({ data: { ...args, password } })
// 3
const token = jwt.sign({ userId: user.id }, APP_SECRET)
// 4
return {
token,
user,
}
}
But when I try the function on GraphQL Playground for example with:
mutation {
signup(
name: "Esteban"
email: "esteban#gmail.com"
password: "Password"
age: 23
height: 1.84
weight: 70.0
goals: ["WEIGHT_LOSS"]
) {
token
user {
id
}
}
}
I get the following error:
{
"data": {
"signup": null
},
"errors": [
{
"message": "\nInvalid `context.prisma.user.create()` invocation in\n/Users/estebankramer1/Documents/ITBA/pf-proyf/server/src/resolvers/Mutation.js:10:42\n\n 6 // 1\n 7 const password = await bcrypt.hash(args.password, 10)\n 8 \n 9 // 2\n→ 10 const user = await context.prisma.user.create({\n data: {\n email: 'esteban#gmail.com',\n password: '$2a$10$hL1sMErBEcg98hpk5kRNpef2isI5d/O66zfRom8sQyThIHue7ku2O',\n name: 'Esteban',\n age: 23,\n height: 1.84,\n weight: 70,\n goals: [\n 'WEIGHT_LOSS'\n ]\n }\n })\n\nUnknown arg `0` in data.goals.0 for type UserCreategoalsInput. Available args:\n\ntype UserCreategoalsInput {\n set?: List<String>\n}\n\n",
"locations": [
{
"line": 2,
"column": 3
}
],
"path": [
"signup"
]
}
]
}
I don't know what I am doing wrong and I cannot find examples of Mutations with lists of strings.

Answer 1

It turns out I needed to change the mutation to the following:
async function signup(parent, args, context, info) {
// 1
const password = await bcrypt.hash(args.password, 10)
// 2
const user = await context.prisma.user.create({ data: {
...args,
goals: {
set: args.goals
},
password
} })
// 3
const token = jwt.sign({ userId: user.id }, APP_SECRET)
// 4
return {
token,
user,
}
}
Basically use a set operation.
I have no idea why, the documentation of Prisma is terrible. Maybe someone can clear things a bit?
