Simple Object Serializer

This gem transforms a sequence of objects into one by selecting only the desired properties of them

Instalation

Add this line to your application's Gemfile:

gem 'simple_object_serializer', git: 'https://github.com/almirpask/simple_object_serializer', branch: 'master'

Then run the bunlde command

Usage

For now this gem only provides to you a view helper which you can use to merge your objects eg:

@user = User.find(2)
@product = Product.first
my_car = {
  brand: 'Ford',
  model: 'Mustang'
  fabrication_yar: '2010'
}
serialize_objects({user: @user, product: @product, my_car: my_car}, {user: [:name], product: [:name, :price], my_car: [:brand, :model]})

# =>
{
  user: {
    name: 'Nick Fury'
  },
  product: {
    name: 'Chair',
    price: '40.00'
  },
  my_car: {
    brand: 'Ford',
    model: 'Mustang'
  }
}

Passing full objects

To pass full objecets you need to pass a object parameter empty like this:

@user = User.find(2)
@product = Product.first
my_car = {
  brand: 'Ford',
  model: 'Mustang'
  fabrication_yar: '2010'
}
serialize_objects({user: @user, product: @product, my_car: my_car}, {user: [:name], product: [:name, :price], my_car: []})

# =>
{
  user: {
    name: 'Nick Fury'
  },
  product: {
    name: 'Chair',
    price: '40.00'
  },
  my_car: {
    brand: 'Ford',
    model: 'Mustang'
    fabrication_yar: '2010'
  }
}

Passing a simple array

@user = User.find(2)
@product = Product.first
animals = ['dog', 'cat', 'dolphin']
serialize_objects({user: @user, product: @product, animals: animals}, {user: [:name], product: [:name, :material], animals: []})

# =>
{
  user: {
    name: 'Nick Fury'
  },
  product: {
    name: 'Chair',
    price: '40.00'
  },
  animals: ['dog', 'cat', 'dolphin']
}

Passing a array of objects

users = User.all

serialize_objects({users: users}, {users: [:name]})

# =>
{
  users: [
    {
      name: 'Tonny Stark'
    },
    {
      name: 'Nick Fury'
    },
    {
      name: 'Steve Rogers'
    }
  ],
}

serialize_objects({users: users}, {users: []})


# =>
{
  users: [

    {
      id: 1
      name: 'Tonny Stark',
      email: 'tonny.stark@avengers.com'
    },
    {
      id: 2
      name: 'Nick Fury',
      email: 'nick.fury@avengers.com'
    },
    {
      id: 3
      name: 'Steve Rogers',
      email: 'steve.rogers@avengers.com'
    }
  ],
}

TODO

Make this gem run with Active Record relationships
Extend the functionalities to controllers
Allow to pass parameters without having to specify the properties (if exist a parameter without the property specification just show this entire object on results)
