A simple question that's been bugging me:
Regarding a "FooDocument/BarMethod": How do I reference the content of
FooDocument inside BarMethod? At the moment, I'm using
<dtml-var "this()">
which seems to call the __str__ method of FooDocument; or
<dtml-var "_.getitem(_['id'],1)"
where I want to render dtml too.
My questions are:
1) is 'this()' intended to be used like this?
2) is there a nicer way of doing the getitem() shenanigans? It seems like a
common enough task to warrant a shortcut. I feel I may be being extra dumb
here.
That's just me thinking aloud. My actual problem, however, is that although
content_a/view_1
returns a view of content_a, I'd like to apply in turn a new view to the
result, e.g.
content_a/view_1/tableise
The concept being that content (content_a, content_b) can be rendered in
different ways (view_1, view_2) but is always displayed inside a table
(tableise).
If I do a <dtml-var "_.getitem(_['id'],1)"> in both view_1 and tableise, I
get infinite recursion, of course. But I can't think of how else I might do
it. Putting <dtml-var "this()"> in tableise makes all the HTML in view_1
render html-safe (< > etc). I was tableise to display view_1's HTML
but not render its DTML.
Any idea, anyone?
Thanks, seb
