adonis-model-utilities

A set of tools to use within your AdonisJS models

1. Install

Install npm module:

$ adonis install adonis-model-utilities

2. Register provider

Once you have installed adonis-model-utilities, make sure to register the provider inside start/app.js in order to make use of it.

const providers = [
  'adonis-model-utilities/providers/ModelUtilitiesProvider'
]

3. Use:

Uuid Trait:

Add trait to the model that will make a new model instance using node uuid

class User {

  static super () {
    super.boot()

    /**
     * Uuid trait
     */
    this.addTrait('@provider:IgorTrinidad/Uuid', { field: 'id', version: 'v4'})
  }

}

This trait create an model instance with id node uuid v4 string

You can change the uuid version to v1, v3, v4 or v5.

Example of migration using Uuid Hook

class UserSchema extends Schema {
  up () {
    this.create('users', (table) => {
      table.uuid('id').index().unique().notNullable()
    })
  }
  down () {
    this.drop('users')
  }
}

Password Hash Trait:

Add trait to the model and set the field that should apply the Hash method of own Adonis framework:

class User {

  static super () {
    super.boot()

    /**
     * PasswordHash trait
     */
    this.addTrait('@provider:IgorTrinidad/PasswordHash', {field: 'password'})
  }

}

this model above is exactly same as:

/** @type {import('@adonisjs/framework/src/Hash')} */
const Hash = use('Hash')

class User extends Model {

  static get hidden () {
    return ['password']
  }

  static boot () {
    super.boot()
    /**
     * A hook to hash the user password before saving
     * it to the database.
     */
    this.addHook('beforeSave', async (userInstance) => {
      if (userInstance.dirty.password) {
        userInstance.password = await Hash.make(userInstance.password)
      }
    })

  }

}

module.exports = User

Format Currency Trait:

Add trait to the model and set the fields that should be formatted:

class Product {

  static super () {
    super.boot()

    /**
     * Format currency trait
     */
    this.addTrait('@provider:IgorTrinidad/FormatCurrency', {fields: ['value'], prefix: 'formatted', symbol: 'US$ '})
  }

}

This trait apply add computed property (virtual) for the model, not changing the original field with prefix "formatted" eg: formattedPrice: "R$ 105,45"

Trait options (*optional)

  {
    prefix: "formatted", //defaul model attribute prefix like formattedValue
    symbol : "US$ ",   // default currency symbol is '$'
    format: "%s%v", // controls output: %s = symbol, %v = value/number (can be object: see below)
    decimal : ",",  // decimal point separator
    thousand: ".",  // thousands separator
    precision : 2   // decimal places
  }

Format Date Trait:

Add trait to the model and set the fields that should be formatted:

class User {

  static super () {
    super.boot()

    /**
     * Format date trait
     */
    this.addTrait('@provider:IgorTrinidad/FormatDate', {fields: ['bday'], unformatted: 'YYYY-MM-DD',formatted: 'DD/MM/YYYY'})
  }
  

}

Trait options (*optional)

  {
    fields: ['bday'],
    unformatted: 'YYYY-MM-DD', //*optional
    formatted: 'DD/MM/YYYY', //*optional
    setter: true, //*optional
    getter: true //*optional
  }

You can set the trait to only apply the getter, setter or both to the field before save on the db or fetch the data

This trait shouldn't be used on created_at and updated_at columns or dates setted using AdonisJS dates mutator

Title Case Trait:

Add trait to the model and set the field that should be TitleCase:

class User {

  static super () {
    super.boot()

    /**
     * Title case
     */
    this.addTrait('@provider:IgorTrinidad/TitleCase', { fields: ['firstName', 'lastName'] })
  }

}

this trait apply a setter on defined fields so all fields will be saved with Title Case (first char uppercase for each word of the string)

FullName Trait:

Add trait to the model and set the trait options:

class User {

  static super () {
    super.boot()

    /**
     * FullName trait
     */
    this.addTrait('@provider:IgorTrinidad/FullName', {
      fullName: 'fullName',
      firstName: 'firstName',
      lastName: 'lastName'
    })
  }

}

this trait apply a setter to the column formating the fullName for the on saving

Parse Number Trait:

Add trait to the model and set the field that should be ParseNumber:

class User {

  static super () {
    super.boot()

    /**
     * Parse Number
     */
    this.addTrait('@provider:IgorTrinidad/ParseNumber', { fields: ['value_one', 'value_two'] })
  }

}

this trait apply a getter on defined fields to parse numbers, this may be necessary if your db engine are formating number columns with too much zero decimals as string
