Using Ruby on Rails I want a confirmation page before creating an ActiveRecord object. The user will see a preview of the item they are creating before submitting and the object being saved in the database
A common pattern;
How would you implement it?
Another option to solve this issue adding by a virtual confirmation attribute to your model. This way, there is no need to create a separate action for this:
class MyRecord < ActiveRecord::Base
attr_accessor :confirmation
validates_acceptance_of :confirmation, :on => :create
end
Now, your new object will not save correctly because the validation will fail on the confirmation field. You can detect this situation and present something like this:
<% form_for(@my_record) do |form| %>
...
<%= form.check_box :confirmation %> Really create this record.
<%= submit_tag('Confirm') %>
<% end %>
I would probably add a "preview" action to the routes.rb file for that model:
map.resource :objects, :new => { :preview => :post }
You would get to this preview action by POSTing the preview_object_url named route. You would need to essentially create the Object in the same way you would in your create action, like this:
def preview
@object = Object.new(params[:object])
end
This page would then POST to the create action, which would then create the Object. It's pretty straight forward.

A few options
1- store the object you want to create in the session until you hit the confirm page, then just save it
2- pass around the object w/ each Post/submit from new -> details -> confirm
I would probably go with 2, since I am not prone to saving state with the session.
I'm not sure how to do this (RoR is new to me) but you could just specify the action for /new as /confirm, and then it calls create.
Right?
