Answer 1

With rails_or, you could do it like:

Account.where(id: 1).or(id: 2)

(It works in Rails 4 and 5, too.)

Answer 2

Sadly, the .or isn't implemented yet (but when it is, it'll be AWESOME).

So you'll have to do something like:

class Project < ActiveRecord::Base
  scope :sufficient_data, :conditions=>['ratio_story_completion != 0 OR ratio_differential != 0']
  scope :profitable, :conditions=>['profit > 0']

That way you can still be awesome and do:

Project.sufficient_data.profitable

Answer 3

Those arel queries are unreadable to me.

What's wrong with a SQL string? In fact, the Rails guides exposes this way as the first way to make conditions in queries: http://guides.rubyonrails.org/active_record_querying.html#array-conditions

So, I bet for this way to do it as the "Rails way":

Account.where("id = 1 OR id = 2")

In my humble opinion, it's shorter and clearer.
