@codenameryuu/adonis-lucid-soft-deletes

This addon adds the functionality to soft deletes Lucid Models through the deleted_at flag in AdonisJS.

Requirement

• Adonis Js 7
• Lucid 22 or higher

Installation

• Install the package

yarn add @codenameryuu/adonis-lucid-soft-deletes

• Configure the package

node ace configure @codenameryuu/adonis-lucid-soft-deletes

• Make sure to register the provider inside adonisrc.ts file.

providers: [
  // ...
  () => import('@codenameryuu/adonis-lucid-soft-deletes/provider'),
],

You should add the deleted_at column to your database tables for models with soft deletes.

// migrations/1234566666_users.ts
import { BaseSchema } from '@adonisjs/lucid/schema'

export default class extends BaseSchema {
  protected tableName = 'products'

  async up() {
    this.schema.createTable(this.tableName, (table) => {
      // ...
      table.timestamp('deleted_at').nullable()
    })
  }
  // ...
}

Applying Soft Deletes to a Model

import { compose } from '@adonisjs/core/helpers'
import { SoftDeletes } from '@codenameryuu/adonis-lucid-soft-deletes'

import { ProductSchema } from "#database/schema";

export default class Product extends compose(ProductSchema, SoftDeletes) {
  // ...columns and props
}

Now, when you call the .delete() method on the model, the deleted_at ( customDeletedAtColumn ) column will be set to the current date and time. However, the model's database record will be left in the table.

import type { HttpContext } from '@adonisjs/core/http'
import Product from '#models/product'

export default class ProductsController {
  /**
   * Delete product by id
   * DELETE /products/:id
   */
  async destroy({ request, response }: HttpContext) {
    const product = await Product.findOrFail(request.input('id'))
    await product.delete()

    return product // or response.noContent()
  }
}

:boom: Soft delete only works for model instances. await Product.query().delete() as before will delete models from database

:point_right: When querying a model that uses soft deletes, the soft deleted models will automatically be excluded from all query results.

To determine if a given model instance has been soft deleted, you may use the .trashed getter:

import type { HttpContext } from '@adonisjs/core/http'
import Product from '#models/product'

export default class ProductsController {
  /**
   * Get product by id
   * GET /products/:id
   */
  async show({ request, response }: HttpContext) {
    const product = await Product.withTrashed().where('id', request.input('id')).firstOrFail()
    if (product.trashed) {
      return response.forbidden()
    }
    return product
  }
}

Restoring Soft Deleted Models

To restore a soft deleted model, you may call the .restore() method on a model instance. Also, method .restore() exists after methods .withTrashed() and .onlyTrashed()

The restore method will set the model's deleted_at column to null :

import type { HttpContext } from '@adonisjs/core/http'
import Product from '#models/product'

export default class TrashProductsController {
  /**
   * Update trashed product by id
   * PUT /trash/products/:id
   */
  async update({ request }: HttpContext) {
    const product = await Product.withTrashed().where('id', request.input('id')).firstOrFail()
    await product.restore()

    return product

    // or

    await Product.withTrashed().where('id', request.input('id')).restore()
    await Product.query().withTrashed().where('id', request.input('id')).restore()
  }
}

Permanently Deleting Models

Sometimes you may need to truly remove a model from your database. You may use the .forceDelete() method to permanently remove a soft deleted model from the database table:

import type { HttpContext } from '@adonisjs/core/http'
import Product from '#models/product'

export default class ProductsController {
  /**
   * Delete product by id
   * DELETE /products/:id
   */
  async destroy({ request, response }: HttpContext) {
    const product = await Product.findOrFail(request.input('id'))
    await product.forceDelete()

    return response.noContent()
  }
}

Including Soft Deleted Models

As noted above, soft deleted models will automatically be excluded from query results. However, you may force soft deleted models to be included in a query's results by calling the .withTrashed() method on the model:

import type { HttpContext } from '@adonisjs/core/http'
import Product from '#models/product'

export default class ProductsController {
  /**
   * Get a list products
   * GET /products?withTrashed=1
   */
  async index({ request }: HttpContext) {
    return Product.query()
      .if(request.input('withTrashed'), (query) => {
        query.withTrashed()
      })
      .paginate(request.input('page', 1), request.input('perPage', 10))
  }
}

Retrieving only Soft Deleted Models

The .onlyTrashed() method will retrieve only soft deleted models:

import type { HttpContext } from '@adonisjs/core/http'
import Product from '#models/product'

export default class TrashProductsController {
  /**
   * Get a list trashed products
   * GET /trash/products
   */
  async index({ request }: HttpContext) {
    return Product.onlyTrashed().paginate(request.input('page', 1), request.input('perPage', 10))
  }
}

Soft Deletes methods

Methods .withTrashed() , .onlyTrashed() and .restore() also available in ModelQueryBuilder for models with soft delete, example:

await Product.query().withTrashed().paginate(request.input('page', 1), request.input('perPage', 10))
await Product.query().onlyTrashed().paginate(request.input('page', 1), request.input('perPage', 10))
