# 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
# end
#

# Returns columns for this *fake* table

end
# Resets all the cached information about columns, which will cause them to be reloaded on the next request.
