Question

I’m using Rails version 3.0.9 and jquery.
The problem is that when you click on the link, the div is not updated.
There are two actions: “show” and “time”. Initial position – show.
Controller code was (ajax_controller.rb):

class AjaxController < ApplicationController
  respond_to :html, :js

  def show  
  end

  def time
  end
end

By clicking on the link in the div should be loaded time.

Next code (show.html.erb):

<h1>Ajax show</h1>
Click this link to show the current 
<%= link_to "time", :url=>{:action => "time"}, :remote => true%>.<br/>
<div id='time_div'>
</div>

Also, there are files time.html.erb and time.js.erb.
Follow code (time.js.erb):

$('#time_div').html('<%= escape_javascript(render :text => "The current time is #{Time.now.to_s}") %>');

But nothing happens. jquery connected.
In what may be the problem?

Answer 1

You can have issues with routes. Do you have something like this in your routes.rb?

RAILS_ROOT/config/routes.rb

get '/time', :to => 'ajax_controller#time', :as => :ajax_time

and then you should call the url with rails helper like this

<%= link_to "time", ajax_time_path, :remote => true %>
