This was already saved in my database :

c.lawsuit.customer\_service\_location

=\> “— !ruby/object:Address \nattributes: \n created\_on: 2006-02-24  
12:30:19 \n city: Alex City\n line1: 441 Saint Bernard Drive\n zip:  
“35086”\n ‘’\n id: “124”\n contact\_detail\_id: “128”\n detail\_key:  
Home Address \n state: AL”

AND I DO THIS

> > my\_test = YAML.load c.lawsuit.customer\_service\_location

=\>#\<YAML::Object:0xb7986eb8 @class=“Address”,  
@ivars={“attributes”=\>{“line1”=\>“441 Saint Bernard Drive”, “city”=\>“Alex  
City”, “created\_on”=\>“2006-02-24 12:30:19”, “line2”=\>"", “zip”=\>“35086”,  
“id”=\>“124”, “state”=\>“AL”, “detail\_key”=\>“Home Address”,  
“contact\_detail\_id”=\>“128”}}\>

## PROBLEM

> > my\_test.city  
> > NoMethodError: Undefined ‘city’ for #YAML::Object:0xb7986eb8  
> > from (irb): 93  
> > from : 0

## THE QUESTION

How I can call city’s value like doing below :

call\_address = Address.find 128  
=\> #\<Address:0xb79076ac @attributes={“created\_on”=\>“2006-02-24  
12:30:19”, “city”=\>“Alex City”, “line1”=\>“441 Saint Bernard Drive”,  
“zip”=\>“35086”,  
“line2”=\>"", “id”=\>“124”, “contact\_detail\_id”=\>“128”,  
“detail\_key”=\>“Home  
Address”, “state”=\>“AL”}\>

call\_address.city  
=\> “Alex City”

Thank You

It should work so long as the environment where you load the YAML has  
the correct definition of the Address class. In your first example  
(where it isn’t working right), you should be able to add something  
before your YAML.load like:

require ‘address’

where the file address.rb has the class definition of Address. Without  
that, Ruby can’t actually instantiate the Address class so you just  
get the YAML::Object object that you’re seeing.
