Extra attributes

[Paulo Fernando Larini]

Hi, how can I send an extra attribute (not defined in the fisical
table) to flex ?

If you're wanting to add an attribute to a model object you can use
write_attribute:

I thing that it is not the case. Look, I have a model like this:

class Person < ActiveRecord::Base

attr_accessor :age

end

or

class Person < ActiveRecord::Base

def age
#calculate the age here
.....
end

end

When sending this objet to flex, I need that the the "age" value goes too.

Correct, using attr_* doesn't work, it doesn't set an ActiveRecord
attribute.

Look-up write_attribute in ActiveRecord::Base
http://ar.rubyonrails.org/classes/ActiveRecord/Base.html

This took about 1/2 a day to figure-out the first time I ran into it :-

You could also add a method in the ClassMappings, like so:

ClassMappings.register(
:actionscript => "com.myapp.vo.PersonVO",
:ruby => "Person",
:type => "active_record",
:attributes => ["id", "name", "email"],
:methods => ["age"])
