Vagrant: Built Customize Vagrant Box

Built Customize Vagrant Box

We can make customize box from our vagrant existed box. With this, we can change our environment in existing box and customize it according our need.


// In your Vagrant Init file directory
vagrant up
// Get in to your vagrant environment
vagrant ssh

 * Do your custumize in here
 * For example. I will remove my existing ruby version from vagrant box and change it to new one

sudo apt-get update -y

sudo apt-get install build-essential zlib1g-dev libssl-dev libreadline-dev \
git-core curl libyaml-dev libcurl4-dev libsqlite3-dev apache2-dev -y

curl --remote-name

tar zxf ruby-1.9.3-p194.tar.gz

cd ruby-1.9.3-p194/



sudo make install

// Check if my new ruby version successfully installed
ruby -v

// If succeed quit from vagrant ssh

// Adding your customize box to new box
vagrant package

// Name it
vagrant box add lucid64_with_ruby193

// Check for your new box
vagrant box list

- lucid32
- lucid64
- lucid64_with_ruby193

// Activate your vagrant 
vagrant init lucid64_with_ruby193

Breakman Rails: How to avoid Mass Assignment Warning

Breakman is static analysis security scanner for Ruby on Rails. It's open source vulnerability scanner specifically designed for Ruby on Rails applications. It statically analyzes Rails application code to find security issues at any stage of development.

I will share some trick to avoid Breakman Mass Assignment medium settings warning.
  1. Pay attention to your model relationship. My suggestion always use Nested Attributes .
  2. If necessary used attr_protected to relationship variable key in your model.
Below is some of example case I've solved:
  • Example Case 1 "Without Relationship" :
         Set relationship variable in attr_protected to avoid Breakman warning.
      attr_accessible :name, :description
      attr_protected : user_id
         Do this saving method:
            create :
         data_list = {:name => name, :description => description}
        saving_create =
        saving_create.user_id = user_id
             update :
        data_list = {:name => name, :description => description}
        user_data = self.find_by_id(1)
        user_data.attributes = data_list 
        user_data.user_id = user_id

  • Example Case 2 "With Relationship" :
      attr_accessible :name, :description
      attr_protected : user_id

      has_one :category
      has_many :products

      accepted_nested_attributes :category, :products

            create :
        products = []
        data_list = {:name => name, :description => description}
        saving_create =
        saving_create.user_id = user_id
        all_data.each do |d|
          saving_process =
          saving_process.product_id = d[:product_id] 
          saving_process.product_name = d[:product_name]
      update :
        products.each do |p|
        data_list = {:name =>, :description => p.description}
         update_process = self.find_by_id(p.user_id)
         update_process.attributes = data_list
         update_process.product_id =
         update_process.product_name =
            raise ActiveRecord::Rollback
