A URL of loncapa.msu.edu/adm/roles?role=$role&symb=$symb
replacing $role with st./$domain/$courseid, and $symb with the unique identifier for the resource (available from: Course Editor > Content Utilities > List Resource Identifiers) works at MSU with the SSO service in use here.  (See: bugs.loncapa.org/show_bug.cgi?id=3987 )

However, use of a more elegant short url of the form: /tiny/$domain/$key, where $domain is course domain, and $key is a unique six character key has now been implemented. (The tiny urls in a course are managed via: Course Editor > Content Utilities > "Display/Set Shortened URLs for Deep-linking").

There are three enhancement requests in bugs.loncapa.org, all with a target milestone set to 2.12, related to the use of deep linking to a specific resource or folder in a LON-CAPA course.

For more information see:
bugs.loncapa.org/show_bug.cgi?id=6400 (Tiny URL for deep linking)
bugs.loncapa.org/show_bug.cgi?id=6906 (Option for LON-CAPA load balancer to record offload node)
bugs.loncapa.org/show_bug.cgi?id=6907 (Content in a course can be set to be deep-link only)

The state of both 6400 and 6906 is currently set to resolved, whereas 6907 is set to assigned (and is 95% complete).

The "deep-link only" functionality (bug 6907) is flagged for 2.12, because if it is enabled in a course, selecting a role in the course will require that the user session is hosted on a 2.12 LON-CAPA server/VM.  

As usual that is enforced by an entry in the /home/httpd/lonTabs/releaseslist.xml file, which in this case is:
<parameter name="deeplink" valuematch="on">2.12</parameter>

Great!  Thank you Stuart.

Also somewhat related, what is the status of deep linking? One of our upcoming scenarios involves using another campus LMS LTI integration with ProctorTrack for authentication with a call back to Lon-Capa to take an exam. How sweet it would be with SSO in place to land the student directly on the exam page rather than on the Lon-Capa courses page.

 Thanks,
Doug

    Doug,

    In course context all files for which the content handler in LON-CAPA is either lonxml.pm or lonhomework.pm have access to styles defined in a published .css file set via a cssfile parameter, made applicable to the current resource.

    Those files include uploaded or published files with an html, htm, xhtml, xhtm, or xml extension, and published resources with a task, problem, exam, or survey extension (or indeed the "simpleproblem" template item in a course).

    Those same files will also be impacted by styles defined in any published .sty files associated with a course via Settings > Course Settings >  Display (Display of resources checked), and included in a comma separated list of paths to style files entered in the "Default XML style file" textbox.

    Standard LON-CAPA pages such as /adm/navmaps (for a Course Contents listing) do not currently include links to published .css files, and do not support modification (based on target and tag) using a published .sty file.

    I have added an enhancement request
    (see: bugs.loncapa.org/show_bug.cgi?id=6904 ) to add a course setting to allow a Course Coordinator to choose which columns should be displayed in the Contents listing. (The "Due in less than 24 hours" warning is in the "long_status" column).

    On a related note, LON-CAPA 2.12 will include the ability to suppress menu links to, and display of /adm/navmaps in specific contexts, i.e., the Placement Test course container, and when LON-CAPA is launched as an LTI Provider, (when the LTI scope is a folder, or a single resource).

    HI All,

    I'm probably in over my head on this one, but I'm looking at a very nice sty file example and attempting to work from that to create a sty file that simply inserts a style sheet that will not display the remaining time on a timed assessment on the content page.

    I know that doesn't sound like a very good idea, but the use is very specific. We are experimenting with a stand-alone instance of Lon-Capa as an exam server. The testing facility we are using likes their proctors, not the LMS, to be in charge of the time, so ideally perhaps we would not use a timer at all for these exams. However, there are a couple of logistical reasons that push the user of the timer for these. I have hidden all evidence of the timer on the problem page itself using css, but as far as I know (and think I've been told) there is no "natural" way to attach a style sheet to the contents page.  Because the only thing in these instances of the course are the exams themselves, it looks to me like the following should hide the time remaining information that displays once the timer has been started:

    <style type="text/css">
    td span[title="Due in less than 24 hours!"]{display:none;}
    </style>

    However, so far my feeble attempts to get that inserted into the contents page via a sty file are coming up empty. I added some more obvious css into my attempted style file injection that have no effect either, so I'm guessing I'm failing so far to get the style code inserted into that (or any other) page.

    If it can't be done it's not the end of the world, but there are so few things that can't be done in Lon-Capa, I thought it was worth asking about.  Thanks!

    Doug
