Is there built in support in rails for the default value substitution idiom?

I often write code to provide a default value upon encountering nil/empty value.

E.g:

category = order.category || "Any"
#  OR
category = order.category.empty? ? "Any" : order.category

I am about to extend the try method to handle this idiom.

category = order.try(:category, :on_nill => "Any")
#  OR
category = order.try(:category, :on_empty=> "Any")

I am wondering if Rails/Ruby has some method to handle this idiom?

Note:

I am trying to eliminate repetition of || / or / ? operator based idioms.

Essentially I am looking for a equivalent of try method for handling default substitution scenarios.

Without try method:

product_id = user.orders.first.product_id unless user.orders.first.nil? 

With try method:

product_id = user.orders.first.try(:product_id)

It is easy to implement a generic approach to handle this idiom, but I want to make sure I do not reinvent the wheel.
