I am working with rails 2.0.2 and ActiveResource

I have an object @person and I need to save it locally and send the same  
object with Active Resource to a Restfull server…  
My solution to this is to define a  
@person.new(params[:person]) and a RestFullPerson hooked on  
ActiveResource::Base  
the problem is when I do a save of the Restfull person it need a hash  
structure  
so I can’t do the following:

result = RestfullPerson.new(@person)

I can’t get any to\_hash methods to work. any ideas are welcome

I’m not 100% sure i’ve understood your question, but is  
@person.attributes what you’re after ?

Thanks Fred.

This is exactly what I was looking for. You might also want to point  
out that you can also do this

@person.attributes.to\_options!

That will symbolize the keys, to make it look like the params[] field  
that is passed to the controller
