I'm currently trying to wrap my head around the below issue, and not getting very far. Currently, I'm running an Apollo-Server as my graphQL server, have prisma2 configured with a postgres database, and am utilizing graphql-codegen to generate the types from my schema. Currently, I'm trying to update a model that has a many-to-many relationship and getting really strange typescript errors being thrown. I'm pretty sure I'm doing the update incorrectly, but the errors I'm seeing aren't helpful.
The following is the pertinent code snippets:
prisma.schema
model Permission {
id Int @id @default(autoincrement())
verb PermissionVerb
resource PermissionModel
own Boolean @default(true)
roles Role[]
}
model Role {
id Int @id @default(autoincrement())
name String
permissions Permission[]
}
enum PermissionModel {
USER
ORDER
CUSTOMER
PERMISSION
ROLE
}
enum PermissionVerb {
CREATE
READ
UPDATE
DELETE
}
permission.gql
extend type Mutation {
updatePermission(input: UpdatePermissionInput): PermissionResult!
}
union PermissionResult = Permission | PermRoleNotFoundError
type Permission {
id: Int!
own: Boolean
resource: PermissionModel!
verb: PermissionVerb!
roles: [Role]
}
type Role {
id: Int!
name: String!
permissions: [Permission]
}
type PermRoleNotFoundError {
message: String!
}
enum PermissionModel {
USER
ORDER
CUSTOMER
PERMISSION
ROLE
}
enum PermissionVerb {
CREATE
READ
UPDATE
DELETE
}
and finally the offending code in the resolver:
updatePermission.ts
export const updatePermission: Resolver<
ResolversTypes['UpdatePermissionInput'],
{},
Context,
RequireFields<MutationUpdatePermissionArgs, never>
> = async (_parent, args, context, _info) => {
const { id, verb, resource, own } = args.input
const oldPermission = await context.prisma.permission.findFirst({
where: { id },
include: { roles: true }
})
const newPermission = await context.prisma.permission.update({
where: { id },
data: {
id: oldPermission.id,
verb: verb ? verb : oldPermission.verb,
resource: resource ? resource : oldPermission.resource,
own: own ? own : oldPermission.own,
},
})
return newPermission
}
I'm getting the following typescript warning:
Type '(_parent: {}, args: RequireFields<MutationUpdatePermissionArgs, never>, context: Context, _info: GraphQLResolveInfo) => Promise<...>' is not assignable to type 'Resolver<UpdatePermissionInput, {}, Context, RequireFields<MutationUpdatePermissionArgs, never>>'.
Type '(_parent: {}, args: RequireFields<MutationUpdatePermissionArgs, never>, context: Context, _info: GraphQLResolveInfo) => Promise<...>' is not assignable to type 'ResolverFn<UpdatePermissionInput, {}, Context, RequireFields<MutationUpdatePermissionArgs, never>>'.
Type 'Promise<Permission>' is not assignable to type 'UpdatePermissionInput | Promise<UpdatePermissionInput>'.
Type 'Promise<Permission>' is not assignable to type 'Promise<UpdatePermissionInput>'.
Type 'Permission' is not assignable to type 'UpdatePermissionInput'.
Types of property 'verb' are incompatible.
Type 'import(\"/Users/jrichardson/Documents/Projects/wsw/node_modules/.prisma/client/index\").PermissionVerb' is not assignable to type 'import(\"/Users/jrichardson/Documents/Projects/wsw/backend/src/generated/graphql\").PermissionVerb'.
Type '\"CREATE\"' is not assignable to type 'PermissionVerb'.
I don't understand why it thinks the PermissionVerb is not assignable - as from what I can see from .prisma/client/index and the generated/graphql, both enums are identical. Not sure what I'm missing here.
Any help would be greatly appreciated! Thanks
the prisma enum not assignable to the graphql enum .. thats the problem
Cast the return by the type of the graphql..
import { Permission as PermissionQL } from "../../generated/graphql";
...
return newPermission as PermissionQL;
In that way I solve the same problem.
