EOX Tagging

Eox-tagging is an openedx plugin, part of the Edunext Open edX Extensions (aka EOX), that adds the capability to tag edx-platform objects. These tags can be used to categorize, include extra information, and so on.

Installation

1. Add this plugin in your Tutor config.yml with the OPENEDX_EXTRA_PIP_REQUIREMENTS setting.

   OPENEDX_EXTRA_PIP_REQUIREMENTS:
      - eox-tagging=={{version}}

2. Save the configuration with tutor config save.

3. Build the image and launch your platform with tutor local launch.

The plugin is configured for the latest release (Quince). The following changes in the plugin settings should be applied to be used for previous releases. Those settings can be changed in eox_tagging/settings/common.py` or, for example, in the instance configurations.

🚨 If the release you are looking for is not listed, please note:

• If the Open edX release is compatible with the current eox-tagging version (see Compatibility Notes), the default configuration is sufficient.
• If incompatible, you can refer to the README from the relevant version tag for configuration details (e.g., v5.1.0 README).

Usage

See the How to section for detailed guidance on model, configurations and API usage.

Important notes:

• All the comparisons with string objects are case insensitive.
• If a tag owner is not defined, then it is assumed to be the site.

Examples

Example 1:

{
    "validate_tag_value": {
        "in": [
            "example_tag_value",
            "example_tag_value_1"
        ]
    },
    "validate_access": {
        "equals": "PRIVATE"
    },
    "validate_target_object": "OpaqueKeyProxyModel",
    "owner_object": "User",
    "tag_type": "tag_by_example"
}

This means that:

• Tag value must be in the array
• The field access must be equal to private
• The target type must be equal to CourseOverview
• The owner type must be equal to User
• Tag_type must be equal to tag_by_example

Example 2:

{
    "validate_tag_value": {
        "exist": true
    },
    "validate_access": "Public",
    "validate_target_object": "User",
    "tag_type": "tag_by_edunext"
}

This means that:

• The tag value must exist, it can take any value.
• The field access must be equal to public.
• The target type must be equal to User.
• Tag type must be equal to tag_by_edunext.

Example 3:

{
    "validate_tag_value": "tag_value",
    "validate_access": {
        "in": [
            "Private",
            "Public"
        ]
    },
    "validate_target_object": "CourseEnrollment",
    "tag_type": "tag_by_edunext",
    "validate_activation_date": {
        "exist": true,
        "in": [
            "Dec 04 2020 10:30:40",
            "Oct 19 2020 10:30:40"
        ]
    }
}

This means that:

• The tag value must be equal to tag_value.
• The field access can be private or public.
• The target type must be equal to CourseEnrollment
• Tag type must be equal to tag_by_edunext.
• The tag activation date must exist between the values defined in the array. This means, value_1 <= activation_date <= value_2. The array must be sorted or a validation error will be raised.

Auditing Django views

The majority of views in eox-tagging use an auditing decorator, defined in our custom library called eox-audit-model, that helps save relevant information about non-idempotent operations. By default, this functionality is turned off, to enable it, install eox-audit-model.

Check your auditing records in Django sysadmin > DJANGO EDUNEXT AUDIT MODEL.

For more information, check the eox-audit-model documentation.
