I am trying to setup a relationship type in Grandstack. I am having issues getting things to run correctly. Even when I copy the guide into my project and try to run it ... things do not work. Here is what they have at https://grandstack.io/docs/guide-graphql-schema-design
type Actor {
actorId: ID!
name: String
movies: [Movie] @relation(name: "ACTED_IN", direction: OUT)
}
type Movie {
movieId: ID!
title: String
description: String
year: Int
actors(limit: Int = 10): [Actor] @relation(name: "ACTED_IN", direction: IN)
similarMovies(limit: Int = 10): [Movie] @cypher(statement: """
MATCH (this)<-[:ACTED_IN]-(:Actor)-[:ACTED_IN]->(rec:Movie)
WITH rec, COUNT(*) AS score ORDER BY score DESC
RETURN rec LIMIT $limit
""")
}
type User {
userId: ID!
name: String
rated: [Rated]
}
type Rated @relation(name: "RATED") {
from: User
to: Movie
rating: Float
review: String
}
The problem is when I run this I get the following error:
ApolloError: The 'from' argument of the @relation directive on the _UserRated type is "User", but a "User" field is not defined.
at validateRelationTypeNodeField (/Users/kennyv/git/skoutal-server/node_modules/neo4j-graphql-js/dist/augment/types/relationship/relationship.js:221:13)
at validateRelationTypeDirective (/Users/kennyv/git/skoutal-server/node_modules/neo4j-graphql-js/dist/augment/types/relationship/relationship.js:183:5)
Not sure why it thinks the User field is not defined. Here is my server.js file
require("dotenv").config();
const { ApolloServer, PubSub } = require("apollo-server");
const jwt = require("jsonwebtoken");
const neo4j = require("neo4j-driver");
const { augmentSchema, makeAugmentedSchema } = require("neo4j-graphql-js");
const typeDefs = require("./graphql/typeDefs.js");
const resolvers = require("./graphql/resolvers");
require("console-stamp")(console, { pattern: "mm/dd/yyyy HH:MM:ss.l" });
// Create an instance of Express
const pubsub = new PubSub();
const PORT = process.env.PORT || 5000;
const schema = makeAugmentedSchema({
typeDefs,
resolvers,
// config: {
// query: true,
// mutation: true,
// },
});
const augmentedSchema = augmentSchema(schema);
const driver = neo4j.driver(
process.env.NEO4J_URI || "bolt://localhost:7687",
neo4j.auth.basic(
process.env.NEO4J_USER || "neo4j",
process.env.NEO4J_PASSWORD || "neo4j"
)
);
const server = new ApolloServer({
schema: schema,
context: ({ req }) => {
const token = req?.headers?.authorization?.slice(7);
let userId;
if (token) {
const decoded = jwt.verify(token, process.env.APP_SECRET);
userId = decoded.id;
}
return {
cypherParams: { userId },
driver,
neo4jDatabase: process.env.NEO4J_DATABASE,
req,
pubsub,
};
},
});
"apollo-server": "^2.20.0",
"graphql": "^15.5.0",
"neo4j-driver": "^4.2.2",
"neo4j-graphql-js": "^2.19.2",
I was accidentally running
const augmentedSchema = augmentSchema(schema);
on a schema that I had already ran
makeAugmentedSchema({
typeDefs,
resolvers,
// config: {
// query: true,
// mutation: true,
// },
});
This was an artifact of moving away from makeExecutableSchema which I had to remove because it was causing issues.
namely:
Error: Unknown directive "@relation".
Unknown directive "@relation".
Unknown directive "@cypher".
Unknown directive "@relation".
Unknown directive "@relation".
Unknown directive "@relation".
So when i commented out the augmentSchema things started working fine.
