I'm doing queries like this in Rails 3.x
Speaker.where("name like '%yson%'")
but I'd love to avoid the DB specific code. What's the right way to do this?
If there's a way to do this in Rails 2.x too, that would help too.

ActiveRecord::Base indicates that the ActiveRecord class or module has a static inner class called Base that you're extending. Edit: as Mike points out, in this case ActiveRecord is a module... ActiveRecord is defined as a module in Rails, github.com/rails/rails/tree/master/activerecord/lib/…
Active Record is the M in MVC - the model - which is the layer of the system responsible for representing business data and logic. Active Record facilitates the creation and use of business objects whose data requires persistent storage to a database.
Ruby. 2018-05-09 · 2 min read. In Rails, pluck is a shortcut to select one or more attributes without loading the corresponding records just to filter out the selected attributes. It returns an Array of attribute values.
In Rails 3 or greater
Speaker.where("name LIKE ?", "%yson%")
In Rails 2
Speaker.all(:conditions => ["name LIKE ?", "%yson%"])
Avoid to directly interpolate strings because the value won't be escaped and you are vulnerable to SQL injection attacks.
