Hi, i want to know if it's posible to change the value of one object in one node. For example, I have extended the article class, now it has a new intenger attribute, what I want is that this attribute get incremented every time the node it's viewed.
In the template for viewing this article I put something like this
{set $node.data_map.volumen.data_int = inc($node.data_map.volumen.data_int) }
where volume is the integer attribute that I want to increment.. I'd apreciate any idea
thanks
Hugo

Hi, as i understand it, templates are just "viewing" the content of the objects (attributes), but the cannot modify it. So, your attempt will not work. I guess, that you need an "operator", which might give you access to writing an attribute to the database. What do you want to do? If you want a view-counter, i suggest, that you analyze the webserver log.If you really need/want the data in the db, read about "workflows". There is a trigger called "after_read" or so, that might help you.
