Re: Using CacheHelper to cache JSON views

I having the same exact issue with  2.2.4. Did you ever find a way to get this to work?

I cannot get this to work in 2.2. This is what I have tried:

First I just followed the book to create JSON views (http://book.cakephp.org/2.0/en/views/json-and-xml-views.html). Works great. I get JSON data back.

Then I followed the CacheHelper instructions (http://book.cakephp.org/2.0/en/core-libraries/helpers/cache.html). I un-commented Cache.check in core.php, added the CacheHelper in my Controller and defined $cacheAction. This works great for HTML Views. But, for JSON views nothing gets cached unfortunately.

I found this post: http://lars-schenk.com/cached-json-or-xml-view-with-cakephp/523 that ran into a similar issue (albeit in an earlier version of Cake that didn't have JsonView yet).

So I tried to use his method, and apply it to 2.2. I took Router::parseExtensions( 'json' ) out, took the RequestHandler out, created a json.ctp layout file.

  <!--nocache--><?php  configure::write('debug',0); // surpress all debug output on json views  header('Content-type: text/x-json');  ?><!--nocache--><?php echo $this->fetch('content'); ?>
 

a feed.ctp view file

  <?php echo json_encode( $data ); ?>
 

and changed my controller action to just set the layout and data

  $this->layout = 'json';  $this->view = 'feed';  $this->set( 'data', $data );
 

This works somewhat. I get the JSON file the first time, but when I request that action again, the response contains

  <!--nocache:001--><!--nocache:002-->
 

before the actual JSON data, so it won't work for my client app. I can see that chunk of text in the actual cache file as well, which I think is the problem.

So I am not quite sure how to proceed.

Am I just missing something painfully obvious?

Any help would be greatly appreciated.
