= nullify

<tt>nullify</tt> makes it easy to clean up blank attributes that result from creating ActiveRecord objects directly from form params. You may specify any number of attributes (including non-column attributes) to nullify.

== Installation

  script/plugin install git://github.com/laserlemon/nullify.git

== Example

In your model:

  class User < ActiveRecord::Base
    validates_presence_of :first_name, :last_name
    nullify :middle_name
    
    def name
      [first_name, middle_name, last_name].compact.join(' ')
    end
  end

In your "new" view:

  <% form_for @user do |f| %>
    <%= f.text_field :first_name %>
    <%= f.text_field :middle_name %>
    <%= f.text_field :last_name %>
    <%= submit_tag 'Save' %>
  <% end %>

In your controller:

  def create
    @user = User.create(params[:user])
  end

In your "show" view:

  <%=h @user.name %>
