Overview

This class create a fake table that can be usefull if you need for example perform validations. Take a look to this test case:

Examples:

  class Contact < Lipsiadmin::DataBase::WithoutTable
    column :name, :string
    column :company, :string
    column :telephone, :string
    column :email, :string
    column :message, :text

    validates_presence_of :name, :message
    validates_format_of :email, :with => /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\Z/i
  end

Now we need to validate a contact, and if the validations is okey send an email or if not raise errors

@contact = Contact.new(params[:contact])
if @contact.valid? 
  Notifier.deliver_support_request(@contact)
else
  flash[:notice] = "There are some problems"
  render :action => :support_request
