Does Rails 4 have support for OR queries

Question

So in Rails 4 the long desired feature to use not queries has been added.

Article.where.not(title: 'Rails 3') 

Has similar support been added for or queries, or are they planning to make it. I couldn't find anything by browsing through the release notes.

Obviously I tried

Article.where(title: 'Rails 3').or(title: 'Rails 4') 

But that does not work.

Answer 1

Article.where(title: ['Rails 3', 'Rails 4']) 

is how you'd do that in Active Record.

It's not possible to replicate any arbitrary SQL query using "Rails-y" syntax. But you can always just pass in literal sql.

So you could also do:

Article.where("articles.title = 'Rails 3' OR articles.title = 'Rails 4'") 

Answer 2

This now works in Rails 5:

Article.where(title: 'Rails 3').or(Article.where(title: 'Rails 4')) 

Code example in Rails's source.
