Steven Stieng	Thursday 27 May 2010 7:48:37 am I have the following code which returns a random article: {def $random_articles=fetch('content', 'list', hash('parent_node_id', 72, 'offset', rand(0,4), 'limit', 1))} {foreach $random_articles as $article} {$article.name\|wash} {/foreach} My problem is that a new article is not loaded when I hit the F5, because the page is cached. I've even tried removing {cache-block}, but that didn't help. How can I get around this problem?
Gaetano Giunta	Thursday 27 May 2010 9:12:45 am If this is inside a node view template, you should set the cache_ttl to 0 (or a few seconds). see http://ez.no/doc/ez_publish/technical_manual/4_x/reference/template_functions/variables/set_block Principal Consultant International Business Member of the Community Project Board
Steven Stieng	Friday 28 May 2010 12:07:50 am But won't {set-block scope=global variable=cache_ttl}0{/set-block} turn of caching for the entire page?
Gaetano Giunta	Friday 28 May 2010 12:27:50 am Indeed. Maybe that's not what you want - but you did not specify a lot of detail in your original post... Probably you can achieve what you want by: - setting cache_ttl to disable view cache for entire page - use a cache block around the part of the template that displays current node (using subtree_expiry as key) - optionally use a 2nd cache block arolund your random articles list Principal Consultant International Business Member of the Community Project Board
Steven Stieng	Friday 28 May 2010 12:51:16 am The random article is shown on the front page, in a section set for news. The other elements may be cached, but not the news box - since a new article should be loaded foreach page reload. So if I put a second cach block around my news container, and inside this I put the cache_ttl, then I should be turning off caching for just that part?
André R.	Friday 28 May 2010 1:27:06 am No it turns of cache for the whole view, cache_ttl only affects view cache as you have on content/view, it will not affect cach-blocks in the view or in your pagelayout. This is why setting it to for instance 30 or 60 seconds might be enough for you, as in do you really* need a new item on every single page reload? If you do, consider preloading something like ten random items at a time and use javascript to select one of them on every single load, or load the whole block with ajax or something. *view: the content ($module_result.content) on your page that is relevant to the url your on, excluding dynamic headers, menues, footer and anything else from your pagelayout. Only content/view/.. ur's are cached with view cache, hence the full name of the cache "Content view cache". eZ Online Editor 5: http://projects.ez.no/ezoe \|\| eZJSCore (Ajax): http://projects.ez.no/ezjscore \|\| eZ Publish EE http://ez.no/eZPublish/eZ-Publish-Enterprise-Subscription @: http://twitter.com/andrerom
