Forum LAMS for Tech-Heads - General Forum: LAMS MOODLE 3.0x Integration not working

I've done the necessary changes to make it work with Moodle 3.

Download the attached mod_lamslesson.zip and replace it and you should be alright.

Thanks,

Ernie

The new plugin installs fine but there is a bug.

I cannot "Open Lesson" from Moodle (However, "Update this LAMS Lesson" and "Monitor this lesson" works fine).

This is really weird. I'd say that the http request URL that is defined on the LAMS side is not working but then I cannot understand why monitoring or authoring should work.

http://tecfalms.unige.ch/moodle/mod/lamslesson/userinfo.php?ts=%timestamp%&un=%username%&hs=%hash%*rname%&hs=%hash%

In addition, the Moodle debugging shows the following in the LAMS screen:

Notice: Undefined property: stdClass::$displaydesign in /data/portails/moodle/moodle/mod/lamslesson/view.php on line 86

- greetings ! Daniel

Yes, I saw that now.

Also, I found a few other bugs with LAMS latest and Moodle 3, so I'll be fixing them shortly.

Now, are you on LAMS 2.4? From the debian installer?

The reason I'm asking is because I probably need to give you a version of the LAMS-Moodle module that is specific for Moodle3 and your version of LAMS too.

Thanks,

Ernie

Posted by Ernie Ghiglione

thanx for looking into this again :)

Yes I got 2.4 from the Debian installer (on Ubuntu 14LTS)

2.4.0.201204131000 I believe

- greetings - Daniel

I'd be glad to have even a half-baked fix. I made the mistake of upgrading Moodle in our production system and not testing LAMS.

We gave our students LAMS sequences to create in two of our classes. While it's possible to look at these directly from LAMS, it's difficult to find out which of the multiple versions they create and deploy is the one to evaluate (Moodle leaves a copy, each time a sequence is redeployed)

- cheers ! Daniel

I certainly can survive our exam sessions without this patch, but I am a quite embarrassed for breaking our system and not testing the upgrade as I should have :(

Posted by Daniel Schneider

No worries, I'll get on to this today.

As soon as I get it done, I'll email you the correct copy.

Cheers,

Ernie

Posted by Ernie Ghiglione

Ok, so here's the LAMS-Moodle module that would work with LAMS version 2.4 and Moodle 3.x.

Let me know if you have any problems.

Thank you,

Ernie

Posted by Ernie Ghiglione

thanx so much for looking into this !

But I am afraid that you packaged the wrong files.

The zip you pointed at has the same size as the one you created on May 20 and files inside look the same too.

http://lamscommunity.org/dotlrn/file-storage/view/dotlrn_fs_1348_root_folder/dotlrn_fs_1348_shared_folder/lams24-moodle3-lamslesson.zip

Unpacked, this zip looks the same, Moodle btw. doesn't recognize any changes and the bug is still there :)

This morning, before attending a meeting I quickly tested and indeed it failed (also moodle did not seem to notice that I changed the files).

But, now, after flushing the browser and server caches, the thing seems to work. Sorry, I shouldn't post when in a hurry.

So it all seems to be OK for now. If not I'll be back :)

- Daniel

PS: Message to all of you: If you install the new LAM-Moodle 3 connector, empting caches could help (can't say which one of Moodle, LAMS or webbrowser did the trick though ...)

Posted by Daniel Schneider

Actually lesson creation is still broken or it broke by itself (can't remember if it actually did work). Since last week we only had to grade finalized sequences I forgot to test. But now students ran into this in another class:

When clicking on "Update this LAMS session", one has to wait a few minutes then get:

Call to LAMS failed: received no response or connection was refused. Please check that you have the correct LAMS server URL and that it is online.

error/lamslesson/restcallfail

Any ideas why this happens ?

- greetings ! - Daniel

In the apache log I can see the following:

I also noticed that Moodle detects a huge lag which is strange since both Moodle and LAMS sit on the same machine and host.

LAMS time: 01-01-1970 01:00:00.000000
Moodle time:06-02-2016 15:47:29.000000

Sorry for the delay.

I tried to replicate the problem you were experiencing today but wasn't able to do.

Here's a little video I did to demonstrate.

Perhaps I'm doing something different?

Thanks,

Ernie

Posted by Ernie Ghiglione

Ouch bad news. Your video demonstrates exactly what the integration should do. (In particular the towards the end, i.e. editing/selecting a LAMS lesson).

Can I do something to provide you with more data ?
