Following instructions and try using graphql-compose-mongoose in NestJS project
import { Field, Int, ObjectType } from '@nestjs/graphql';
import { Prop, Schema, SchemaFactory } from '@nestjs/mongoose';
import { schemaComposer } from 'graphql-compose';
import { composeMongoose } from 'graphql-compose-mongoose';
import mongoose from 'mongoose';
@Schema({ timestamps: true })
@ObjectType()
export class Cat {
@Prop()
@Field(() => String)
name: string;
@Prop()
@Field(() => Int)
age: number;
@Prop()
@Field(() => String)
breed: string;
}
const schema = SchemaFactory.createForClass(Cat);
const CatModel = mongoose.model('Cat', schema);
const CatTC = composeMongoose(CatModel, {});
schemaComposer.Query.addFields({
catById: CatTC.mongooseResolvers.findById(),
});
export const CatSchema = schemaComposer.buildSchema();
But got error at const CatTC = composeMongoose(CatModel, {});
Argument of type 'Model<Cat, {}, {}, {}, Schema<Cat, Model<Cat, any, any, any, any>, {}, {}, {}, {}, DefaultSchemaOptions, Cat>>' is not assignable to parameter of type 'Model<Document<any, any, any>, {}, {}, {}, any>'.
The types returned by 'castObject(...)' are incompatible between these types.
Type 'Cat' is not assignable to type 'Document<any, any, any>'.ts(2345)
I can pass any generic const CatModel = mongoose.model<any>('Cat', schema);
but still having problem
NestJS saying
[Nest] 11348 - 15.01.2023, 20:05:21 ERROR [ExceptionHandler] The 2nd parameter to `mongoose.model()` should be a schema or a POJO
Error: The 2nd parameter to `mongoose.model()` should be a schema or a POJO
Schema injected in nestjs at module file
cat.module.ts
import { Module } from '@nestjs/common';
import { MongooseModule } from '@nestjs/mongoose';
import { Cat, CatSchema } from './cat.model';
import { CatService } from './cat.service';
import { CatResolver } from './cat.resolver';
@Module({
imports: [MongooseModule.forFeature([{ name: Cat.name, schema: CatSchema }])],
providers: [CatService, CatResolver],
})
export class CatModule {}
Another way - cloning example and seen you using any heneric too export const Category = model<any>('Category', CategorySchema);
If i remove it i got error
Argument of type 'Model<unknown, {}, {}>' is not assignable to parameter of type 'Model<Document<any, any, any>, {}, {}>'.
Types of property 'find' are incompatible.

Types of parameters 'callback' and 'callback' are incompatible.
Types of parameters 'result' and 'result' are incompatible.
Type 'unknown[]' is not assignable to type 'Document<any, any, any>[]'.
Type 'unknown' is not assignable to type 'Document<any, any, any>'.ts(2345)
If update packages to latest version - got same error as in my own project
Based on the above, there are two questions:
- How using package without generic?
- How integrate with NestJS?
