Order confirmation page in rails.

Question

Hi guys,

I've been trying to create an order confirmation page for my rails app, and am not quite sure how to go about it in a restful way.

There were a few answers on this question that got me halfway there, but the problem was that I wasn't quite sure how to set up the form in the rails view so that it would take the user to a confirmation page with all their details instead of a create action.

Right now my view is simple:

        <% form_for :order do |f| %>
      <%= f.error_messages %>
      <p>
        <%= f.label :first_name %><br />
        <%= f.text_field :first_name, :size => 15 %>
      </p>
      <p>
        <%= f.label :last_name %><br />
        <%= f.text_field :last_name, :size => 15 %>
      </p>
      (Be sure to enter your name as it appears on your card)
      <p>
        <%= f.label :card_type %><br />
        <%= f.select :card_type, [["Visa", "visa"], ["MasterCard", "master"], ["Discover", "discover"], ["American Express", "american_express"]] %>
      </p>
      <p>
        <%= f.label :card_number %><br />
        <%= f.text_field :card_number %>
      </p>
      <p>
        <%= f.label :card_verification, "Card Verification Value (CVV)" %><br />
        <%= f.text_field :card_verification, :size => 3 %>
      </p>
      <p>
        <%= f.label :card_expires_on %><br />
        <%= f.date_select :card_expires_on, :discard_day => true, :start_year => Date.today.year, :end_year => (Date.today.year+10), :add_month_numbers => true %>
      </p>
  <p><%= f.submit "Submit" %></p>

What things should I be doing to direct the user to a confirmation page that shows all the order details?

Thanks!

Answer 1

Why don't you pull the confirmation via ajax for example, pull the result and put it as an overlay div, upon confirmation submit the original values in the form.

If you still need to do it your way then check wizardly, it's exactly designed for such uses.

Directing a form to a non standard page is pretty simple.

Add a url option form_for. Such that

<% form_for :order do |f| %>

becomes

<% form_for :order :url => {:action => "confirm"} do |f| %>

You'll need to crate the confirm action in your routes, but that only involves this:

map.resources :orders, :collection => {:confirm => :get}

All you need now is a basic controller action and a view:

def confirm
  @order = Order.new(params[:order])
  unless @order.valid?
    render :action => :new
  else       
  end
end

Your view should look almost identical to the show view, with the addition of a form submitting @order to the create action.
