Compare with:

Converts a collection of elements into a formatted string by calling to_s on all elements and joining them:

Blog.find(:all).to_formatted_s # => "First PostSecond PostThird Post"

Adding in the :db argument as the format yields a prettier output:

Blog.find(:all).to_formatted_s(:db) # => "First Post,Second Post,Third Post"

Parameters

format opt = :default
