I have two tables (Person and User) that are related as follows:

1 class Person \< ActiveRecord::Base  
2  
3 def user  
4 return User.find(:first, :conditions =\> [“person\_id = ?”, self]  
5 end  
6  
7 def user\_name  
8 return self.user.name  
9 end

I wish to update them both simultaneously with form\_remote\_tag like  
this:

1 \<%= form\_remote\_tag(:url =\> {:action =\> ‘update’, :id =\> @person})%\>  
2 First Name: \<%= text\_field ‘person’, ‘first\_name’ %\>  
3 User Name: \<%= text\_field ‘person’, ‘user\_name’ %\>  
4 \<%= submit\_tag ‘Save’ %\>  
5 \<%= end\_form\_tag %\>

with this code in the controller:

1 def update  
2 @person = Person.find(params[:id])  
3 if @person.update\_attributes(params[:person])  
4 return if request.xhr?  
5 render :partial =\> ‘info’  
6 end  
7 end

I’m guessing I can accomplish this by changing something in the  
controller, but I’m stuck at the moment. Any ideas?

</div>

this did it:

view:  
\<%= text\_field “user”, “name” %\>

controller:  
@person = Person.find(params[:id])  
@person.update\_attributes(params[:person])  
@person.user.update\_attributes(params[:user])
