wicked wizard passing arguments to steps - process

Question

I would like to make a smooth streamlined process for placing customer orders.
I feel the best tool for the job is a wizard - unless there are other suggestions?
I need to pass arguments to next steps in my wizard.
My controller looks like this:
include Wicked::Wizard
steps :item, :customization, :upsell
def show
# #order_session_id = params[:order_session_id]
#order = Order.new
#order.order_session_id = params[:order_session_id]
case step
when :item
#items = Item.all # change with group...
when :customization
# item = Item.find(#order.item_id)
# item = Item.find(params[:item_id])
item = Item.find(1)
#customizations = item.customizations.split("|")
when :upsell
#upsells = Upsell.find_all_by_group_id(item.group_id)
end
render_wizard
end
def update
#order_session_id = params[:order_session_id]
#order.attributes = params[:order]
render_wizard #order
end
The view for item looks like this:
<%= form_for #order, url: wizard_path(:customization), :method => :get do |f| %>
<table border="1">
<% #items.each do |item| %>
<tr>
<td class="item_selection" onclick="$(this).children('input').attr('checked', 'checked');return false;">
<%= f.label :item_id, "#{item.name}" %>
<%= f.radio_button(:item_id, item.id) %>
</td>
</tr>
<% end %>
</table>
<div class="actions">
<%= f.submit "Continute" %>
</div>
<% end %>
I need to pass the selected item_id to the customization step so that the next part of the wizard can work.
How can I do this?
Thanks

You can pass parameters in the url after the step parameter.
wizard_path(:step_1, item: item)
