I'm attempting to write a replacement for Plone CAS Login for Plone 3.0,
since the product hasn't been updated.
The 2.5 product changed the login portlet and the login form to go to
CAS. I've decided it is more elegant to simply have the "login" link on
the personal bar link to the CAS server login form and get rid of the
portlet and login form altogether, because, since the CAS server gathers
the username and password, there is no need for an entire portlet or
form - a link is just right.
Or maybe some JS that redirects/reloads on startup?
Unfortunately, the CAS server needs to know whether javascript and
cookies are enabled and this info is harvested on the linking page via
javascript and passed via the form parameters (the form method is GET)
to the CAS server.
I don't know how to do this from a GenericSetup action registration. It
simply takes a URL which, while it can by dynamic, can't AFAICT include
javascript. Does anyone see how I can produce these urls from action
definitions?
Why not just have it point to a view that works this out and then
performs an immediate redirect?
This reminds me of a post I made a few weeks ago that received no
replies entitled "Vertically Stacked Dynamic Links in Document Actions".
Maybe because it had a terrible title? :-)
It's short, so I'll include it here:
#####
I want to get an entry on the document actions line that has multiple
links. Example: stacked on top of each other, "Atom Feed", "RSS2 Feed",
and "RSS Feed", each going to a separate url. But I don't want them
distributed horizontally, as separate document actions would have it.
Also, they must be dynamic based on the context - folder A may have all
3, while folder B lacks the RSS2 feed. I tried inserting another viewlet
into the manager, but so far haven't gotten it to work. So I'm asking
for advice...
This leaves me asking, "what did you try"... Did you fail to install a
viewlet? Did you fail to make it have the layout you want? There's not
enough information here to help you. If I ignored the post the first
time, it was probably because of the open-ended question. ;-)
#####
A viewlet can be made to work - as can a bunch of regular actions and
some creative CSS. At the end of the day, this comes down to CSS.
I am guessing that, if I hit the similar problems twice in two very
different contexts in a few weeks, either I have a systematic
misunderstanding or there's a real challenge here. It seems to me that
it would be nice if actions were more flexible, to be able to render a
nested viewlet as well as a URL. This would give product authors much
more flexibility. What do y'all think?
I don't think it'd be appropriate to change the actions machinery for
this. If actions aren't flexible enough for you, you're most likely
going to be able to register a new viewlet, order it properly, and style
it with CSS.
