Create controllers and views in Ruby on Rails plugins


Many times we are comfortable save to the database data structures like arrays or hashes .

 In Ruby on Rails we can do it easily with the method of ActiveRecord  
 serialize. This method allows you to save objects in a field of the database in text format. Uses YAML to convert the object to text. < ActionController::Base
 
 
  

class Example serialize: data end

Now we can use the class as follows Example:

Ejemplo.create eg = (: data => {'key1' = > 'attribute1', 'key2' => 2}) puts ej.datos ['key2']

Using serialize
we can save many lines of code)
