What is the folder structure of the problog package? I have the pronews package and I would modify the root/packages/pronews/blocks/content/templates/news_post/view.php

You should be able to use any of the approaches I do with Magic Data. Have a look at the code in Magic Data Templates and in Magic Yogurt.

In Magic Yogurt the area class extension is a very safe approach.

Which works best all depends on the context.

Thanks for that pointer. I'll take a look there.

Where, in Magic Yogurt, would it be best to look?

Bob

in magic yogurt, look in the page type php files at how the magic data is integrated...

OK, I see what's up.

From a pure MVC point of view, should the logic for "magic" be in the model or in the controller? Ideally, I would have thought in the controller.

Is there a concrete5 best practice?

Bob

So much depends on the situation and at what stage of the page rendering process you want to apply it. Things to consider:
- is the outcome cacheable?
- what happens if it is cached?
- does it depend on who the user is?
- can it change with iterations within a list?
- does it change with time?

Back to the original title, if you look inside the views and templates for pro blog, you will see where magic data is applied within it.
