# MassAssignable

MassAssignable is a simple gem that adds Rails-like mass-assignment behavior

to ordinary Ruby objects. This gem has no external dependencies and works

everywhere.

## Installation

Add this line to your application's Gemfile:

    gem 'mass_assignable'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install mass_assignable

## Usage

Simply include `MassAssignable` in your class and specify mass assignable

attributes using `attr_mass_assignable`. Any attributes not specified

will not be mass assignable.

```ruby

require 'mass_assignable' # not needed with Rails

class Person

  include MassAssignable

  

  attr_accessor :name, :age, :height

  attr_mass_assignable :name, :age

end

```

Then, mass assignment is as easy as calling `attributes=`.

```ruby

person = Person.new

person.attributes = { :name => "Derrick", :age => 24, :height => 77 }

person.name

# => "Derrick"

person.age

# => 24

person.height

# => nil

```

Notice that `#height` is nil, because we didn't include it in our call to

`attr_mass_assignable`.

If you want an error to be raised when invalid mass assignment is attempted,

simply use `attr_mass_assignable!`.

```ruby

class ParanoidPerson

  include MassAssignable

  

  attr_accessor :name, :age, :height

  attr_mass_assignable! :name, :age

end

person = ParanoidPerson.new

person.attributes = { :height => 77 }

# => Raises a RuntimeError

```
