How can I get mt RJS template to accept a variable as the ID value?

Doing this works:  
page.replace\_html ‘1’, “some text…”

This does not:

page.replace\_html @employee.id, “some text…”

Looked and searched but little documentation at the mo especially in  
RDocs.

Not sure, since I didn’t test this, but may this be a class mismatch  
error? Can you try adding .to\_s to your variable?

They are ordinary views

lets assume you have @employee in your action then you can use @employee  
in your rjs

#Controller  
def show  
@user = User.find(params[:id])  
end

#show.rjs  
page.replace\_html “user\_#{@user.id}”, “You know where to find me”
