Based on a simplified rules engine I'm determining what to render to screen.
For flexibility a want to be able to pull html-snippets from a database
(based on these rules) which can contain template expansions. (i.e:
<div>${country.name}</div>).
I want to know if it is possible (in for instance the setupRender or
beginRender phase of the containing page) to expand the fetched html-snippet
to include values based on the current instance for country in this
instance. What service should I call for this (if possible) and what are
possible caveats easing this?
With this I want to tackle the general problem of a-priori not knowing:
- what kind of blocks / modules a page needs to load.
- how many blocks are loaded.
in other words, I can't use delegate to delegate rendering to a particular
block, because this limits me in what (html)context the block is rendered
(the place where the delegate is contained in the template) and it limits me
to render only 1 block per delegate, where every possible delegate must be
defined at design time (and so must be known apriori).
I have seen other posts concerning the same general problem, but haven't
found a definitive solution in these posts. If anyone has a better solution
for the general problem outline above, of course I'm interested as well.
Thanks,
Britske
