Question

I’m serializing a ruby object with

YAML::dump(obj) 

and storing it in a database.
Then I’m calling

myobj = YAML::load(obj)

I can see in debug that the object was succesfully created and it’s fields were initialized.
But when I’m trying to call an attribute, for example “name” like myobj.name, I recieve a “no method error” message. What am I doing wrong, and how can I correctly deserialize the object?BTW I can access fields of my object by calling

myobj.instance_variable_get('@attributes')[:name]

Thanks.

Answer 1

Are you sure your object has a method name?

Can you try a

YAML::dump(obj) 
p obj.name

Just to be sure, the object you store has really a method name.

Your

myobj.instance_variable_get('@attributes')[:name]

doesn’t indicate, that there is a method or attribute name. There is only an attribute @attributes, that supports a method [] (probably a hash).

Perhaps you can use

myobj.attributes[:name]

But without more information, all this are only a guess.
