I am trying to use a query in NodeJS using mongoose + GraphQL.
The model file as:
const mongoose = require('mongoose')
mongoose.set('debug', true);
const Schema = mongoose.Schema
const authorSchema = new Schema({
name: String,
age: Number,
authorId: String,
})
module.exports = mongoose.model('Author', authorSchema)
Schema for author is as below:
const AuthorType = new GraphQLObjectType({
name: 'Author',
fields: () => ({
authorId: {type: GraphQLString},
name: {type: GraphQLString},
age: {type: GraphQLInt},
books: {
type: new GraphQLList(BookType),
resolve(parent, args) {
return book.find({authorId: parent.authorId})
}
},
})
})
The rootQuery:
const RootQuery = new GraphQLObjectType({
name: 'RootQueryType',
fields: {
author: {
type: AuthorType,
args: {authorId: {type: GraphQLString}},
resolve(parent, args){
console.log("Author parent", parent, args)
return Author.find({authorId: args.authorId})
}
},
Now when I am trying to use query from graphiQL using authorId, it returns as null, I have enabled mongoose debug, I see that mongoose sending correct query.
{
author(authorId: "1") {
name
age
authorId
}
}
It returns below
{
"data": {
"author": {
"name": null, <<<<
"age": null, <<<
"authorId": null <<<
}
}
}
But I see that in mongoose log, it sends correctly
Mongoose: authors.find({ authorId: '1' }, { projection: {} })
In my mongo db, I have the data for authorId as below:
Atlas atlas-5p0amv-shard-0 [primary] test> db.authors.find({authorId: '1'})
[
{
_id: ObjectId("63adf57d50ee6abd7cce79ad"),
name: 'Author1',
age: 44,
authorId: '1',
__v: 0
}
]
Atlas atlas-5p0amv-shard-0 [primary] test>
Can you please let me know where I am doing wrong.
Thanks in advance.

As per the comment above, you want Author.findOne
not Author.find
since you'd want a single document, not an array.
