InvalidAuthenticityToken with Lightview

Rails
1

Hi,

I’m integrating Lightview,
http://www.nickstakenburg.com/projects/lightview/, into an application.
It’s more or less a content overlay similar to a light box, which then
calls the content either through an IFRAME or Ajax request. The IFRAME
works fine but for obvious reasons, I’d prefer to use Ajax but whenever
I use that option, I get the dreaded InvalidAuthenticityToken error.

Do any ideas come to mind?

Add this in the section of your main layout file:

 <script type="text/javascript" charset="utf-8">
     window._token = '<%= form_authenticity_token -%>';
 </script>

Add this on top of your /javascripts/application.js file:

Ajax.Base.prototype.initialize = Ajax.Base.prototype.initialize.wrap(
function(p, options){
p(options);
this.options.parameters = this.options.parameters || {};
this.options.parameters.authenticity_token = window._token || ‘’;
}
);

Presto! All ajax requests that are called from your own javascript
code will have the authenticity string added to the parameters.
