openedx-ltistore 1.1.4

An app for storing LTI provider configurations centrally.

Openedx LTI Store

A plugin for openedx-platform to store LTI configurations centrally. This allows course creators to add LTI components without having to enter the details like secrets, keys and URLs everytime the component block is created.

Development

The development instructions are written with the Open edX Devstack as reference.

1. Clone the repostiory to <devstack_root>/src/ directory

   cd <devstack_root>/src/
   git clone [e-mail]:open-craft/openedx-ltistore.git
   

2. Install the plugin inside the Studio container and run migrations

   cd <devstack_root>/devstack/
   make studio-shell
   pip install -e /edx/src/openedx-ltistore
   python manage.py cms migrate lti_store
   exit
   

3. Install the plugin inside the LMS Container

   make lms-shell
   pip install -e /edx/src/openedx-ltistore
   exit
   

4. The LTI Consumer XBlock can fetch configurations to LTI Tools using openedx-filters mechanism. It calls the filter org.openedx.xblock.lti_consumer.configuration.listed.v1 whenever it wants to fetch the configurations from external tools like plugins. In order for LTI Store to send available LTI Tools, add the following to any existing openedx-filters configurations for both LMS (edx-platform/lms/envs/devstack.py or private.py) and studio (edx-platform/cms/envs/devstack.py):

   OPEN_EDX_FILTERS_CONFIG = {
       "org.openedx.xblock.lti_consumer.configuration.listed.v1": {
           "fail_silently": False,
           "pipeline": [
               "lti_store.pipelines.GetLtiConfigurations"
           ]
       }
   }
   

5. Restart the LMS & Studio for the latest config to take effect

   make lms-restart
   make studio-restart
   

Now any changes made to the source code should reflect in the application

Adding LTI Tools to the store

Use configuration on LTI consumer XBlock

1. Go to http://localhost:18000/admin
2. Look for LTI_STORE and go to External lti configurations
3. On the list of external LTI configurations, note down the "Filter Key" value of the configuration to use (Example: lti_store:1).
4. Copy "Filter Key" to the "External ID" field on the LTI consumer XBlock.
