Installing a new XBlock

Allow All Advanced Components (first time only)

Custom XBlocks are not allowed by default, you need to update settings.

Like all platform settings, you can either write inside /edx/app/edx_ansible/server-vars.yml and update the platform to generate the custom settings files.

EDXAPP_FEATURES:
    ALLOW_ALL_ADVANCED_COMPONENTS: true

Or you can manually edit the custom settings, in /edx/app/edxapp/cms.env.json.

This will override the default value hardcoded in /edx/app/edxapp/edx-platform/cms/envs/common.py.

Once the file is updated, you need to reboot to reload the settings.

sudo /edx/bin/supervisorctl -c /edx/etc/supervisord.conf restart edxapp:

Install an XBlock

To install a XBlock, you must download it, and then run the install script.

# Move to the folder where you want to download the XBlock
cd /edx/app/edxapp
# Download the XBlock
sudo -u edxapp git clone https://github.com/xxx/yourXBlock.git
# If not installed: Install the XBlock
sudo -u edxapp /edx/bin/pip.edxapp install yourXBlock/
# Remove the installation files
sudo rm -r yourXBlock

Reboot if something isn't right

In some cases, rebooting is necessary to use the XBlock.

sudo /edx/bin/supervisorctl -c /edx/etc/supervisord.conf restart edxapp:

Activate the XBlock in your course

Go to Settings -> Advanced Settings and set advanced_modules to ["xblockname"].

Use the XBlock in a unit

Select Advanced -> XBlock Name in your unit.
