Ignoring a model with all blank fields in Ruby on Rails

I am trying to create multiple items (each with a name value and a content value) in a single form. The code I have is functioning, but I cannot figure out how to ignore items that are blank. Here's the code:

#item.rb
class Item < ActiveRecord::Base
 attr_accessible :name, :content
 validates_presence_of :name, :content 
end

#items_controller.rb
class ItemsController < ApplicationController  

def new
  @items = Array.new(3){ Item.new } 
end

def create
 @items = params[:items].values.collect{|item|Item.new(item)}
 if @items.each(&:save!)
  flash[:notice] = "Successfully created item."
  redirect_to root_url
 else
  render :action => 'new'
 end
end

#new.html.erb
<% form_tag :action => 'create' do %>
 <%@items.each_with_index do |item, index| %>
  <% fields_for "items[#{index}]", item do |f| %>
  <p>
   Name: <%= f.text_field :name  %>
   Content: <%= f.text_field :content  %>
  </p>
  <% end %>
 <% end %>
 <%= submit_tag %>
<% end %>

This code works when all fields for all items are filled out in the form, but fails if any fields are left blank (due to validations). The goal is that 1 or 2 items could be saved, even if others are left blank.

I'm sure there is a simple solution to this, but I've b开发者_运维技巧een tinkering for hours with no avail. Any help is appreciated!

I'd do this:

class Item
  def empty?
    attributes.values.compact.empty?
  end
end

# in ItemsController
if @items.reject(&:empty?).all(&:save)

A couple notes:

1. You were using save!, but you probably want save. save! would raise an exception if one of the items was invalid, and you'd just see an error page instead of your new template.
2. I replaced each with all. each wouldn't do what you intended--which is to return true if and only if all of the Items validated and saved. all does just that.

I'm not sure this is the best solution, but perhaps you could do something like:

@items.reject! { |item| item.attributes.values.compact.empty? }
