[Grok-dev] Trying to understand viewlets

[Àlex Magaz Graça]

Hi,

I've just converted my application to use viewlets instead of only 
views. After the conversion, some doubts have arisen about which is the 
correct way to use them.

Right now, I have all the code in the update() method from the views. 
The viewlets don't have any method, only grok directives binding them to 
views, viewlet managers and templates.

But, as I see it, it should be the other way round. The code in 
Viewlet.update() and only directives in the views. This would allow to 
reuse a viewlet in different views. However, I can't bind a viewlet to 
more than a View. I've tryied the following, but both fail:

class TestViewlet(grok.Viewlet):
     grok.View(SomeView)
     grok.View(SomeOtherView)

     grok.View(SomeView, SomeOtherView)

The use case I'm thinking is for example a viewlet that displays a list 
of objects. I would want to bind it to a view which only shows this 
list, but I would also want to link it to a kind of dashboard view where 
it is rendered along with other viewlets showing other information.

I this the correct/usual way of using viewlets?

Thanks,
Àlex
