ActiveRecord Tableless Models
-----------------------------
A single implementation of the ActiveRecord Tableless Model pattern for any
Rails project or other Ruby project that uses ActiveRecord.
Define a model like this:
class ContactMessage < ActiveRecord::Base
has_no_table
column :name, :string
column :email, :string
validates_presence_of :name, :email
end
You can now use the model in a view like this:
<%= form_for :message, @message do |f| %>
Your name: <%= f.text_field :name %>
Your email: <%= f.text_field :email %>
<% end %>
And in the controller:
def message
@message = ContactMessage.new
if request.post?
@message.attributes = params[:message]
if @message.valid?
# Process the message...
end
end
end
