How to use OR condition in ActiveRecord query

Question

I want to grab all the users that either have an email as the one supplied or the first and last name. So for example:

users = User.where(:first_name => \         


        

Answer 1

Rails 5 comes with an or method.

This method accepts an ActiveRecord::Relation object. eg:

User.where(first_name: 'James', last_name: 'Scott')
    .or(User.where(email: 'james@gmail.com'))
