Rails 3 - how do I avoid database altogether?

Question

I\'m trying to use rails 3 without any db backend, but it still insists on requiring \'sqlite3\' gem when I try to access a page, and throws an error no such file to l

Answer 1

Also, in Rails 3, remove any references to active_record in

config/environments/development.rb

config/environments/test.rb and

config/environments/production.rb such as

config.active_record.mass_assignment_sanitizer = :strict
config.active_record.auto_explain_threshold_in_seconds = 0.5

as well as removing require "rails/all" and adding the require lines in comment 21 (above).

if you are not using a database (this works with Rails 3.1.1)
