to_formatted_s

v2.1.0 - Show latest stable - Class: ActiveSupport::CoreExtensions::Array::Conversions

to_formatted_s(format = :default)

public

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"
