[holaontiveros]

Description

In order to achieve openedx/frontend-app-instructor-dashboard#86 this PR will add use the new filter for the instructor dash tabs

depens on: openedx/openedx-filters#355

Once this is in place any operator / plugin creator can do something like:

# Add the pipeline step to the LMS configuration
hooks.Filters.ENV_PATCHES.add_item(
    (
        "openedx-lms-common-settings",
        """
# Custom tabs plugin configuration and pipeline step
import logging
from django.conf import settings

# Define the pipeline step class
class CustomTabsStep:
    def __init__(self, filter_type, running_pipeline, **kwargs):
        self.filter_type = filter_type
        self.running_pipeline = running_pipeline

    def run_filter(self, tabs, user, course_key, **kwargs):
        logger = logging.getLogger(__name__)
        logger.error(f"DEBUG: CustomTabsStep.run_filter called for user {user.username if hasattr(user, 'username') else 'unknown'}")

        modified_tabs = tabs.copy()

        # Check if user has permission
        user_has_access = (
            getattr(user, 'is_staff', False) or 
            getattr(user, 'is_superuser', False)
        )
        logger.error(f"DEBUG: User access check - is_staff: {getattr(user, 'is_staff', False)}, is_superuser: {getattr(user, 'is_superuser', False)}, has_access: {user_has_access}")

        if not user_has_access:
            logger.error("DEBUG: User does not have access to custom tabs")
            return {"tabs": modified_tabs}

        # Add custom tab
        custom_tab = {
            'tab_id': 'custom_analytics',
            'title': 'Custom Analytics',
            'url': f"{getattr(settings, 'CUSTOM_TABS_URL', '/instructor-dashboard/course-v1:OpenedX+DemoX+DemoCourse/custom_analytics')}",
            'sort_order': 120,
        }

        modified_tabs.append(custom_tab)
        logger.error(f"DEBUG: Added custom tab. Total tabs: {len(modified_tabs)}")

        return {"tabs": modified_tabs}

# Add the class to sys.modules so it can be imported by string
import sys
import types

# Create a module for our custom class
custom_module = types.ModuleType('custom_tabs_module')
custom_module.CustomTabsStep = CustomTabsStep
sys.modules['custom_tabs_module'] = custom_module

# Register the filter configuration
if "OPEN_EDX_FILTERS_CONFIG" not in locals():
    OPEN_EDX_FILTERS_CONFIG = {}

OPEN_EDX_FILTERS_CONFIG.update({
    "org.openedx.learning.instructor.dashboard.tabs.requested.v1": {
        "pipeline": [
            "custom_tabs_module.CustomTabsStep",
        ],
        "fail_silently": False,
    },
})
""",
    )
)

in whichever shape fits their need to be able to conditionally add or modify data of the tabs for the instructor dashboard.

Testing instructions

Note: to test this through the API or the UI edx-filters changes need to be in place

• While having instructor dashbboard app and openedx-platform working add the example tutor-plugin from the description
• Save configs
• Restart server
• Go to instructor dashboard, the new tab should be available

Take in account that the frontend should have a slot to manage the URL that it's being returned for example a slot like this

{
    slotId: 'org.openedx.frontend.slot.instructorDashboard.routes.v1',
    id: 'org.openedx.frontend.widget.instructorDashboard.route.custom_analytics',
    op: WidgetOperationTypes.APPEND,
    element: <PlaceholderSlot tabId="custom_analytics" content={<div>Dynamic Content</div>} />,
  }

is added to the frontend-base build then the custom_analytics from the path from the plugin example will match the tabId custom_analytics from here and the tab will be displayed

The API request that uses this is: http://local.openedx.io:8000/api/instructor/v2/courses/{:courseId}

A couple of items to address, mostly around matching established conventions for filter consumers in this codebase. Also consider moving the filter call before the sort — currently plugin-added tabs will always appear at the end regardless of their sort_order, since the filter fires after sorting. No tests for the filter integration — other filter consumers in edx-platform have tests (e.g., test_instructor_dashboard.py tests InstructorDashboardRenderStarted).
