How to disable the ability to create new preconfigured LTI tools

How to disable the ability to create new preconfigured LTI tools

Hi,

I would like that teachers from our Moodle site would be able to choose from the activity chooser a preconfigured LTI tool (Zoom LTI for instance) but I don't want them to create new preconfigured tools (with their own urls). The problem is that if I disable the capability mod/lti:addpreconfiguredinstance the preconfigured Zoom tool is not shown to teachers on activity chooser but if I enable that capability the teachers are able to add a new tool using the plus sign when editing the LTI zoom module instance in their course (image attached).

add-preconfigured-tool

I want them to use the Zoom preconfigured LTI tool exactly as a module and I don't want them to add new preconfigured tools. Does anyone know if it is possible to achieve that on Moodle 3.9?...

Thank you!

(PS: We have mod/lti:addmanualinstance  disabled for teachers)

Hi Susana,

If you prohibit the capability 'mod/lti:addcoursetool', this should achieve what you're looking for. The "+" symbol is still present but users won't be able to add course tools.

Hope that helps

Hi Jake,

Thank you for your input!

I changed the capability 'mod/lti:addcoursetool' on teacher's role, but the teacher is still able to see the "+" symbol and actually create a new tool that shows up on the list of tools (Site administration> PluginsActivity> modules> External tool> Manage tools).

(Am i missing something... or doing something wrong...?)

Thank you,
susana

Hi Susana,

The + symbol will still be present, but they will see a notice if they try to use it. I've just double checked the code (and the behaviour) and it's definitely the 'mod/lti:addcoursetool' capability that's checked on the instructor_edit_tool_type.php page. Perhaps the user has multiple roles in that context or the capability isn't being set to prohibit.

Hi Jake,

You are absolutely right. My fault. I was changing the capability to Prevent instead of Prohibit...
That's it, just like you said, the '+' sign shows up but the page is not accessible by teachers.

Thank you for your feedback and I'm sorry for my clumsiness! smile

Best,
susana
