Question

I’m a newbye that is trying to do little things in Rails, at the moment I have created an app that build some links and I want to refresh the content of a Div when they are clicked.

In my application.html.erb I have the layout with the next head:

<%= stylesheet_link_tag    "application" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>

(I have read about change the second line for :defaults but if do that I get a 404 error defauls.js)

I have an index.html.erb that render a partial with this:

<%= render :partial => 'masvisitadas' %>

In my _masvisitadas.html.erb I have the code that generate the links:

<%= link_to solution.SolutionName, "/soluciones/despliega/" + solution.Id.to_s, :remote=>true %>

This generate the next html:

http://localhost:3000/soluciones/despliega/501D0000000QWp6IAG

In my controller I have the next def:

def despliega
    respond_to do |format|
        format.js {}
    end
end

Finally I have created despliega.js.erb:

jQuery(function($) {
    var html = "<%= escape_javascript(render('despliega')) %>";
  $("#customTopLeft").prepend(html)
$("customTopLeft").html("<%= escape_javascript(render(:partial => 'despliega')) %>");

});

In the log of the web server when i click a link it seems all going well:

Started GET "/soluciones/despliega/501D0000000QXM0IAO" for 127.0.0.1 at 2012-08-

  Parameters: {"id"=>"501D0000000QXM0IAO"}

  Rendered soluciones/despliega.js.erb (15.6ms)
Completed 200 OK in 31ms (Views: 31.3ms | ActiveRecord: 0.0ms)

And in the firebug I can see the call with any error but nothing happends.
This is killing my head 🙂 Thanks in advance for any help here.
Regards.

What’s in _despliega.html.erb?

Try changing despliega.js.erb to this (and only this):

$('#customTopLeft').html("<%= escape_javascript(render :partial => 'despliega') %>");

Edit – oh, and make sure you have the jQuery libraries included ..
