View page items?

[Alex-Wenner-FHR]

Is there a way to view page items? It seems like q.page['page'].items would be a list by the way we reference it (q.page['page'].items[2]) but I print it out and just get a wave component. I have a lot of elements on one page and struggling to reference it by index. Any thoughts on how I can find exactly what index a specific component is?

Any thoughts on this one? I am was able to find out the element but by doing q.page['page'].items[2], q.page['page'].items[3], q.page['page'].items[4] ... This was very suboptimal, would be nice to see all the elements on a page!

See #148.

There's no way to view the items inside q.page. This is because q.page is not a real collection, but a temporary placeholder for capturing all the modifications you do to the page before you call q.page.save().

In several of the scenarios that Wave supports, it's possible that different scripts/apps write to different parts of the same page, so supplying each q.page in each app instance with a consistent view of what's contained in the actual page is an expensive operation.

I would recommend maintaining a separate dict of items that you add to the page, i.e. instead of using q.page['foo'] = card, call a separate function set_card(q, 'foo', card):

my_cards = dict() # your card collection

def set_card(q, key, card):
    q.page[key] = card
    my_cards[key] = card

This way, you can iterate through my_cards instead of attempting to iterate through q.page.
