Question

From the documentation for link_to_remote

The result of that request can then be inserted into a DOM object whose id can be specified with options[:update]. Usually, the result would be a partial prepared by the controller with render :partial.

For example, one would do this:

<%= link_to_remote( 'Some link text', :url => url, :method => method, :update => 'name_of_partial' %> 

Is there a way to pass a :locals hash to the partial (in the example above, ‘name_of_partial’) similar to when you would render it using ‘render :partial’?

Answer 1

You don’t quite understand. The :update argument is the html id of the element that will have its contents replaced by the contents of the result of this ajax call.

<div id='ajax_message'></div> <%= link_to_remote 'click me',                    :url => my_ajax_action_path,                    :update => 'ajax_message' %> 

The partial in question is rendered in response to the ajax request in your controller.

def my_ajax_action   @my_object = MyOobject.find(params[:id]) #or something   render :partial => 'my_object',          :locals => { :my_object => @my_object } end 

The resulting response body is then shoved into your previously named element via the :update argument.
