Hello,

I’m experimenting with ActiveResouce and created a very simple server  
and client application with a single Person resource.

I am getting the following error when trying to use the new person  
form:

undefined method ‘first\_name’ for #Person:0x215dacc

The same form works fine on the server application using the  
ActiveRecord.

Here is my AR model:

class Person \< ActiveResource::Base  
self.site = “[http://localhost:3000/](http://localhost:3000/)”  
end

And my view:

# New person

\<% form\_for(@person) do |f| %\>  
\<%= f.error\_messages %\>

\<%= f.label :first\_name %\>  
 \<%= f.text\_field :first\_name %\>

\<%= f.label :last\_name %\>  
 \<%= f.text\_field :last\_name %\>

\<%= f.submit "Create" %\>

\<% end %\>

\<%= link\_to ‘Back’, people\_path %\>

The odd thing is that I can create new Person objects from script/  
console.  
p = Person.new(:first\_name =\> “Robert”, :last\_name =\> “Walker”)
