eLearning with Moodle and Adobe Connect @MedIT

Today we finished our first milestone in our MedIT Moodle Adobe Connect integration project.

The first milestone includes:

  • Creating ADC meetings as activities within a Moodle course.
  • Auto enroll course members
  • Single Sign-on for lecturers/students with their corresponding rights.
  • Automatically generated reminders for pending ADC course activities.
  • Viewing ADC sessions is also possible with our mobile application studentsLife (iOS/Android) and the adobe-connectmobile integration.



Moodle 2.3.x ajax marking block PostgreSQL compatibility fix

I just added the wonderful ajax marking block to our Moodle system. After little testing it seems that this block has some issues with our PostgreSQL backend.

In detail one of the major queries are aborting with the meaningful error message:

ERROR: failed to find conversion function from “unknown” to text

nice stuff 🙂

It turns out that the usage of a “string as alias” are not handled correctly in postgresql, or so,… this part needs an explicit cast “::text”

If you also encountered this problem, you can download an updated query_base.class.php from -> here

have fun
