rails Why i can't use order in find method?

Question

In script/console

Storage.find(:all , :conditions => "item_id=1" , order => "expire_date DESC")

i get

NameError: undefined local variable or method `order' for #<Object:0xb7761954>
    from (irb):5

But it works when i use

Storage.find(:all , :conditions => "item_id=1")

Answer 1

order should be a symbol, :order => "expire_date DESC"
