Question

I’m just wondering how to implement database views in Ruby on Rails. Can you guys put some working example? And thank you for every advises and examples.

Answer 1

You mean client-side views on the database or views within the database?

Most relational databases support views which encapsulate a projection or other set-based operation into a virtual table:

CREATE VIEW viewname AS
SELECT *
       ,some_derived_column
FROM basetable
WHERE some_filter_criteria

Rails typically uses a pattern called Active Record to map database tables/views into Ruby for access at that layer. How you deal with it at that point is kind of wide open.
