If I have table user (id, firstname, lastname, age, city)

And form: textboxes for firstname, lastname, age and select for city

Is it possible to auto complete form? Not only firstname or lastname,  
but full form?  
So if I enter lastname, and there is only one user with this name, so it  
auto complete firstname, age and city.

Hello there,  
Why don’t you try a form\_observer to do the job?

Simple example:  
(view)  
\<% form\_for :foo, :id =\> “my\_form” %\>  
\<%= form.text\_field :first\_name%\>  
\<%= form.text\_field :last\_name%\>  
\<%= form.text\_field :age%\>  
\<% end %\>  
\<%= observe\_form :my\_form, :frequency =\> 0.5, :url =\> {:action =\>  
search\_result" } %\>

(controller)  
def search\_result  
@foo = User.find(:all, :conditions =\> [“first\_name LIKE ?, last\_name  
LIKE ?”,params[:first\_name], params[:last\_name]])  
render view again  
end

I don’t now if what you want to do is a good idea, but… that is the  
way I’ll do it (what does not mean that is the best way, I’m new in  
Rails).
