Than I want to call a action which update this section depending on the
data-constellation in the database.
There is no input-field on the page.
It works fine when I create
<%=link_to_remote("dispatchConstraint",:update => "cont",:url =>
{:action => :dispatch, :order_id => @order}) %>
My problem is : I do not want a link on the page. There is no field to
observe and there is no periodic update necessery.
The action is :
def dispatch
if (@order.cont==true)
render :partial => "list"
else
render :partial => "addForm"
end
end
Is there any function to do this ?
What I learned is that the trigger comes from the browser but all
functions I have found need an interaction or is periodically called.
Thanks for any idea

Erhard, if you only want to fill the div when the page is initially
rendered, just make dispatch a helper function, and call it inside
the div.
If instead you want to fill the div based on some unstated
browser event, place a call to the remote_function helper inside
a (template-processed) JavaScript function or a tag event property:
