Prisma

{% hint style="info" %} Before reading this article, make sure you have set up an AdminJS instance using one of the supported Plugins.
Additionally, you should have installed @adminjs/prisma as described in Getting started section. {% endhint %}

This guide will assume you have set up Prisma using it's documentation or Nest.js documentation.

There are small differences in how you connect Prisma to Nest.js vs other plugins, so the guide will be split into two sections accordingly.

Example Prisma schema:

{% code title="prisma.schema" %}

datasource db {
  provider = "mysql"
  url      = env("MYSQL_DATABASE_URL")
}

generator client {
  provider = "prisma-client-js"
}

model Publisher {
  id      Int      @id @default(autoincrement())
  email   String   @unique
  name    String?
}

{% endcode %}

Standard

Make sure you have followed the tutorial for the framework you are using in the Plugins section.

The configuration for non-Nest.js plugins is basically the same for each one of them:

• You must instantiate a Prisma Client before creating AdminJS instance
• You must import AdminJSPrisma adapter and register it
• You must import the entities you want to use and pass them to AdminJS resources options

{% code title="app.ts" %}

// ... other imports
import { Database, Resource, getModelByName } from '@adminjs/prisma'
import { PrismaClient } from '@prisma/client'

const prisma = new PrismaClient()

AdminJS.registerAdapter({ Database, Resource })

// ... other code
const start = async () => {
  const adminOptions = {
    resources: [{
      resource: { model: getModelByName('Post'), client: prisma },
      options: {},
    }, {
      resource: { model: getModelByName('Profile'), client: prisma },
      options: {},
    }, {
      resource: { model: getModelByName('Publisher'), client: prisma },
      options: {},
    }],
  }
  // Please note that some plugins don't need you to create AdminJS instance manually,
  // instead you would just pass `adminOptions` into the plugin directly,
  // an example would be "@adminjs/hapi"
  const admin = new AdminJS(adminOptions)
  // ... other code
}

start()

{% endcode %}

Nest.js

Make sure you have set up your app.module.ts according to Nest.js documentation and you have followed Nest.js plugin tutorial as well.

Your app.module.ts should have imports option which contains:

• AdminModule.createAdminAsync({ ... }

In your app.module.ts add these imports at the top of the file:

{% code title="app.module.ts" %}

import { Database, Resource, getModelByName } from '@adminjs/prisma'
import AdminJS from 'adminjs'

import { PrismaService } from './prisma.service.js' // PrismaService from Nest.js documentation

{% endcode %}

Following this, register AdminJSPrisma adapter somewhere after your imports:

{% code title="app.module.ts" %}

AdminJS.registerAdapter({ Database, Resource })

{% endcode %}

This will allow you to pass Prisma models for AdminJS to load. If we use the Publisher entity that we used as en example earlier, you should import it into app.module.ts and pass it into resources in your adminJsOptions:

{% code title="app.module.ts" %}

// ... other imports
import { Category } from './category.entity.js'
// ... other code
AdminModule.createAdminAsync({
  useFactory: () => {
    // Note: Feel free to contribute to this documentation if you find a Nest-way of
    // injecting PrismaService into AdminJS module
    const prisma = new PrismaService()

    return {
      adminJsOptions: {
        rootPath: '/admin',
        resources: [{
          resource: { model: getModelByName('Post'), client: prisma },
          options: {},
        }],
      },
    }
  }
}),
// ... other code

{% endcode %}

Custom client module

In case your generated client is not under the default path, you can pass clientModule to each resource's configuration:

// other imports
// your custom prisma module
import PrismaModule from '../prisma/client-prisma/index.js';

// ...

const prisma = new PrismaModule.PrismaClient();

// ...

// Notice `clientModule` per resource
const admin = new AdminJS({
  resources: [{
    resource: {
      model: getModelByName('Post', PrismaModule),
      client: prisma,
      clientModule: PrismaModule,
    },
  }],
});
