PseudoModel

ActiveRecord Validations without ActiveRecord? No problem.

Add this line to your application's Gemfile:

gem 'pseudo_model'

And then execute:

$ bundle

Or install it yourself as:

$ gem install pseudo_model

If you want to build form with validations, but you don't need store data to database, this is for you.

For instance, you want calculation request form.

Create app/model/calculation_request.rb and define class from PseudoModel::Base

CalculationRequest < PseudoModel::Base
  attr_acessor :name, :message
  validates :message, :presence => true
end

Now you can use valid? method:

calc_request = CalculationRequest.new
calc_request.valid? #=> false
calc_request.message = "Hello, I want to know how much..."
calc_request.valid? #=> true

In controller you can simply do:

def new
  @calculation_request = CalculcationRequest.new
end

def create
  @calculation_request = CalculcationRequest.new(params[:calculation_request])
  if @calculation_request.valid?
    # send email or something
  else
    render :new
  end
end

Building a form is simple as that:

<%= form_for @calculation_request do |f| %>
  ...
<% end %>
