ActionView::Template::Error (comparison of Fixnum with nil failed):

[yatta20]

Hello I'm a newbie,

Our server went down recently and now I'm getting page not found when I try to purchase a product.

Ruby 1.9.3, Rails 3.21

 

Here's the information from the log file. 

ActionView::Template::Error (comparison of Fixnum with nil failed):

    3: <% end %>

    4: <div id="checkout">

    5:   <h1><%= t("checkout")%></h1>

    6:   <%= checkout_progress %>

    7:   <br clear="left" />

    8:   <%= render "shared/error_messages", :target => @order %>

    9:     <%if @order.state != "confirm"%>

  app/helpers/checkout_helper.rb:16:in `<'

  app/helpers/checkout_helper.rb:16:in `checkout_progress'

  app/helpers/checkout_helper.rb:9:in `map'

  app/helpers/checkout_helper.rb:9:in `checkout_progress'

  app/views/checkout/edit.html.erb:6:in `_app_views_checkout_edit_html_erb___1936024257_23456254125680_0'

 

  app/views/checkout/edit.html.erb

<% content_for :head do %>
  <%= javascript_include_tag  'checkout', '/states' %>
<% end %>
<div id="checkout">
  <h1><%= t("checkout")%></h1>
  <%= checkout_progress %>
  <br clear="left" />
  <%= render "shared/error_messages", :target => @order %>
 <%if @order.state != "confirm"%>
   <%= hook :checkout_summary_box do %>
     <div id="checkout-summary" class="alt">
       <%= render 'summary', :order => @order %>
     </div>
   <% end %>
 <%end%>
 <div id="address_form_container">
   <%= form_for @order, :url => update_checkout_path(@order.state), :html => { :id => "checkout_form_#{@order.state}" } do |form| %>
     <%= render @order.state, :form => form %>
     <input id="post-final" type="submit" style="display:none"/>
   <% end %>
 </div>
</div>

Any ideas?

[Oscar Del Ben]

the error is in checkout_helper line 16. Can you post that method?

> if state_index < current_index

either one or the other is nil, that's your problem.

Hi Oscar,

I'm very new. Do I need to delete the block of code  "if state_index < current_index" ?

No, and we can't help you here because it really depends on the business logic. I recommend you find someone (offline) experienced that helps you with that problem.

Ok thank you

 

[Colin Law]

If it used to work and now does not then something must have changed.
Perhaps you can work out what has changed somehow.
