Convert string to serialize hash

Hello Rubies,

        Do you phase the problem ? - sometime  when we are retrieving the serialized hash field from table we might get string as response. So in that case you can use one of the below solutions.

Eg. 

Model - User.rb

class User < ActiveRecord::Base

   serialize :content, Hash

end

convert string to serialize hash format by 

# get the one of the record from users table

user = User.first

either using

    user.content.to_yaml

or

    YAML.parse(user.content)

or

    YAML.load(user.content)

Serialize and deserialize object in ruby

Hello Rubies,

          Want to serialize and deserialize the ruby object? than use the inbuilt method of ruby.

Assume have the field says 'content' as text field of xyz table and it stores the value in serialize hash format but when we do the sql query to retrieve content than it gives output as normal string format.

content has value:

---
ruby:
  :value: 50

  :label: "ruby %"
java:
  :value: 30
  :label: "java %"
c:
  :value: 50
  :label: "c %"

Lets trying to get the content value by raw sql statement like "select content from xyz" than it return text (string) object.

now we load the object in serialize form by

puts YAML::load(content)

visa versa we have string and set to serialize object than need to use  

puts YAML::dump(content)

Same way around if you have deserialize content and want the serialize form then use content.to_yaml. It gives result in serialized form.
