Edit Question
Title
Body
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.
