Rails: Is there an else statement in if try(:current_order)? -

is possible have else statement in if try()?

the else block ignored:

          <% if try(:current_order) %>             <% if current_order.state != 'complete' && current_order.line_items.count > 0 %>             <%= current_order.line_items.count %>             <% end %>             <% else %>             <%= "&nbsp;".html_safe %>           <% end %> 

i want achieve print out of   if try(:current_order) fails.

update:

    <li class="icon icon-cart">       <%= link_to spree.cart_path %>       <div class="cart">         <%= image_tag("shopping_bag.png", class: 'shopping-bag') %>         <span class="cart-items-count">           <% if current_order %>             <% if current_order.state != 'complete' && current_order.line_items.count > 0 %>               <%= current_order.line_items.count %>             <% end %>           <% else %>             &nbsp;           <% end %>         </span>       </div>       <% end %>     </li> 

i use snippet in header , when open static page no current_order available get:

nameerror in spree::pages#show  undefined local variable or method `current_order' #<#<class:0x007fcd7636c090>:0x007fcd8770e0c0> 

is there easy fix without using try?

why use try here? use current_order itself:

<% if current_order %>   <% if current_order.state != 'complete' && current_order.line_items.count > 0 %>     <%= current_order.line_items.count %>   <% end %> <% else %>   &nbsp; <% end %> 

if current_order nil   shown.

for record, try used avoid calling methods on nil (so e.g. foo.try(:bar) return nil if foo nil, whereas foo.bar raise nomethoderror). not relevant use case here, don't need try.
