set up form.  
[http://jonathanbarket.com/post/78831424/simple-associations-with-ext-scaffold](http://jonathanbarket.com/post/78831424/simple-associations-with-ext-scaffold)  
But, I cannot search country name from manufacture form.  
I want to attach file through ext\_scaffold.

How can I solve them?
