在NestJS集成AdminJS与Prisma时遇NoResourceAdapterError错误求助

问题场景 #

在NestJS(9.0.0)中配置AdminJS(^{6.8.6)与Prisma(}4.9.0)时，向adminJsOptions.resources数组添加指定资源后触发NoResourceAdapterError错误。

问题代码 #

核心资源配置代码 #

const prisma = new PrismaService();
const dmmf = ((prisma as any)._baseDmmf as DMMFClass);
// ...其他代码
{
  resource: { model: dmmf.modelMap.Publisher, client: prisma },
  options: {},
}

完整AppModule代码 #

import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { AdminModule } from '@adminjs/nestjs';
import * as AdminJSPrisma from '@adminjs/prisma'
import AdminJS from 'adminjs'
import { PrismaService } from './prisma/prisma.service';
import { DMMFClass } from '@prisma/client/runtime'

AdminJS.registerAdapter({
  Resource: AdminJSPrisma.Resource,
  Database: AdminJSPrisma.Database,
})

@Module({
  imports: [
    AdminModule.createAdminAsync({
      useFactory: () => {

        const prisma = new PrismaService();
        const dmmf = ((prisma as any)._baseDmmf as DMMFClass);
        return {
          adminJsOptions: {
            rootPath: '/admin',
            resources: [
              {
                resource: { model: dmmf.modelMap.Publisher, client: prisma },
                options: {},
              }
            ],
          }
        }
      },
    }),
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule { }

排查与解决方案 #

1. 适配依赖版本 #

AdminJS Prisma适配器版本需与AdminJS、Prisma版本匹配。当前@adminjs/prisma可能和Prisma 4.9.0不兼容，升级适配器到适配Prisma 4.x的版本：

npm install @adminjs/prisma@latest

2. 修正DMMF获取方式 #

直接访问私有属性_baseDmmf存在兼容性问题，改用Prisma公开的$schema.dmmf属性获取：

// 替换原dmmf获取代码
const dmmf = prisma.$schema.dmmf;

3. 正确注入Prisma实例 #

避免在useFactory中直接实例化PrismaService，通过依赖注入获取已初始化的实例：
修改AdminModule.createAdminAsync配置：

AdminModule.createAdminAsync({
  inject: [PrismaService],
  useFactory: (prisma: PrismaService) => {
    const dmmf = prisma.$schema.dmmf;
    return {
      adminJsOptions: {
        rootPath: '/admin',
        resources: [
          {
            resource: { model: dmmf.modelMap.Publisher, client: prisma },
            options: {},
          }
        ],
      }
    }
  },
}),

同时确保PrismaService在模块的providers数组中。

4. 完整修正后的AppModule示例 #

import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { AdminModule } from '@adminjs/nestjs';
import * as AdminJSPrisma from '@adminjs/prisma'
import AdminJS from 'adminjs'
import { PrismaService } from './prisma/prisma.service';

// 提前注册适配器，确保在AdminModule初始化前完成
AdminJS.registerAdapter({
  Resource: AdminJSPrisma.Resource,
  Database: AdminJSPrisma.Database,
})

@Module({
  imports: [
    AdminModule.createAdminAsync({
      inject: [PrismaService],
      useFactory: (prisma: PrismaService) => {
        const dmmf = prisma.$schema.dmmf;
        return {
          adminJsOptions: {
            rootPath: '/admin',
            resources: [
              {
                resource: { model: dmmf.modelMap.Publisher, client: prisma },
                options: {},
              }
            ],
          }
        }
      },
    }),
  ],
  controllers: [AppController],
  providers: [AppService, PrismaService],
})
export class AppModule { }
