[Rails] JQuery + Rails problem retreiving JSON
Hi guys,
I have a problem retrieving data in JSON format using Ajax with
JQuery.
Here's the code I use:
/app/controllers/stories_controller.rb:
def index
@stories = Story.all
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => @stories }
format.json { render :json => @stories, :callback => params
[:callback] }
end
end
/app/views/layouts/application.html.erb
...
<%= javascript_include_tag "jquery" %>
$(document).ready(function(){
$.getJSON("/stories.json?callback=?", function(data){
alert(data[2]);
});
});
...
Here's the problem I have...
The alert box that pops up diplays the following:
http://localhost:3000
[object Object]
What's worst is that Rails retreives my data and returns it in a
proper JSON format since when
I enter http://localhost:3000/stories.json I get the JSON file
What's wrong with JQuery ??? I do exactly what they say on their
Website
I need help please...
Thx...

All that has been done... I've no problem at all sshing into my instance and cloning the repo from there... It seems that the problem would be with capistrano...

Hey guys,
So here's the deal...
I'm trying to deploy an app on EC2 using the EC2onRails gem
I'm using git as my SCM and capistrano to deploy obviously...
