Running 3.1 since release. I apologize if 3.1.1 or 4.0 will trivialize
my question; I haven't had time to look at either closely, though I do
lurk on the dev list.
I use prototype's Ajax.Updater to drop a teaser for the latest entry in
our blog on our home page, using a custom template that produces the
appropriate HTML fragment. I'm now looking at adding more links into
the blog using similar techniques, and my current task has required a
code change to Roller. I spent several hours poring over source code
and trying different approaches, but I wasn't able to come up with a
satisfactory alternative. I thought I'd ask if there was a better way.
My objective is to associate tags with (non-Roller) pages on our site,
and incorporate links to recent blog entries with those tags. For
example, if a blog entry refers to a brand of products we sell, it will
be tagged with the name of the brand, and I'd like to display a link to
it on the page for that brand, which will be associated with the same
tag. There doesn't seem to be any way to get a list of tagged entries
from a custom page. For about two seconds, I considered using
performing an XSL transformation on a tag filtered RSS feed.
In the end I either needed a $model.getWeblogEntriesPager signature that
takes a tags list, which I could then send down as a request parameter
(though not with the name "tags", since Roller inexplicably removes
reserved keys from the request parameter map), or else I needed
WeblogPageRequest to make use of the "tags" parameter, which it seems to
me it should do anyway, with the simple diff below.
