relation filter is not created

[apss-pohl]

Given this models:

generator client {
  provider        = "prisma-client-js"
  binaryTargets   = ["native", "darwin", "debian-openssl-1.1.x", "linux-musl", "windows"]
  output          = "./dist"
  previewFeatures = ["fullTextSearch", "fullTextIndex"]
}

// configService.get<any>('internal.config.mainDatabaseUrl')
datasource db {
  provider = "mysql"
  url      = env("APP_MAIN_DATABASE_URL")
}

generator nestgraphql {
  provider             = "prisma-nestjs-graphql"
  output               = "../src/@generated"
  outputFilePattern    = "{model}/{plural.type}/{name}.{type}.ts"
  prismaClientImport   = "@m/../prisma/dist"
  combineScalarFilters = false
  noAtomicOperations   = false
  noTypeId             = true
}

model checkin {
  id     Int   @id @default(autoincrement()) @db.UnsignedInt
  areaId Int?  @db.UnsignedSmallInt
  area   area? @relation("checkinRelation", fields: [areaId], references: [id])

  @@map("karena_checkin")
}

model area {
  id      Int       @id @default(autoincrement()) @db.UnsignedSmallInt
  checkin checkin[] @relation("checkinRelation")
}

The generated file:

../../prisma/inputs/area-relation-filter.input

is empty but is needed by

checkin/inputs/checkin-where-unique.input.ts

import { Field } from '@nestjs/graphql';
import { InputType } from '@nestjs/graphql';
import { Int } from '@nestjs/graphql';
import { checkinWhereInput } from './checkin-where.input';
import { IntNullableFilter } from '../../prisma/inputs/int-nullable-filter.input';
import { AreaNullableRelationFilter } from '../../prisma/inputs/area-nullable-relation-filter.input'; // <---- This file is created but empty

@InputType()
export class checkinWhereUniqueInput {

    @Field(() => Int, {nullable:true})
    id?: number;

    @Field(() => [checkinWhereInput], {nullable:true})
    AND?: Array<checkinWhereInput>;

    @Field(() => [checkinWhereInput], {nullable:true})
    OR?: Array<checkinWhereInput>;

    @Field(() => [checkinWhereInput], {nullable:true})
    NOT?: Array<checkinWhereInput>;

    @Field(() => IntNullableFilter, {nullable:true})
    areaId?: IntNullableFilter;

    @Field(() => AreaNullableRelationFilter, {nullable:true})
    area?: AreaNullableRelationFilter;
}

Current versions of prisma and prisma-nestjs-graphql are used

@unlight I also want to add to this issue. previewFeatures = ["relationJoins"] doesn't work either. I'm faced with passing a graphql "include" prisma field. But it is not generated. This is a big drawback of this package that cuts off a large piece of prisma functionality in filtering nested fields

@ArgsType()
export class FindManyOrderArgs {
    @Field(() => OrderWhereInput, {nullable:true})
    @Type(() => OrderWhereInput)
    where?: InstanceType<typeof OrderWhereInput>;
    @Field(() => [OrderOrderByWithRelationInput], {nullable:true})
    orderBy?: Array<OrderOrderByWithRelationInput>;
    @Field(() => OrderWhereUniqueInput, {nullable:true})
    cursor?: Prisma.AtLeast<OrderWhereUniqueInput, 'id'>;
    @Field(() => Int, {nullable:true})
    take?: number;
    @Field(() => Int, {nullable:true})
    skip?: number;
    @Field(() => [OrderScalarFieldEnum], {nullable:true})
    distinct?: Array<keyof typeof OrderScalarFieldEnum>;
    @Field(() => RelationLoadStrategy, {nullable:true})
    relationLoadStrategy?: keyof typeof RelationLoadStrategy;
}

, I had to enter it manually.

@Query(() => [Order], { nullable: false })
 listsOrder(@Args() args: FindManyOrderArgs) {
   return this.orderService.findMany({
     ...args,
     include: {
       client: true,
     }
   })
 }

Here is my config:

generator nestgraphql {
  provider                              = "node node_modules/prisma-nestjs-graphql"
  output                                = "../src/dtos"
  fields_Validator_from                 = "class-validator"
  fields_Validator_input                = true
  requireSingleFieldsInWhereUniqueInput = true
  emitSingle                            = true
  emitCompiled                          = false
  purgeOutput                           = true
  noTypeId                              = true
  previewFeatures                       = ["relationJoins"]
}

i figured out in the meantime that the relation filter is not generated because "areaId" is optional. However AreaNullableRelationFilter must be generated
