Debugging Admin Extensions

Use this when an admin resource, page, widget, field, action, setting, or Extensions page contribution does not appear.

Admin Resolution Flow

flowchart TD
    Provider["Package admin provider boots"] --> Bridge["AdminBridge registered"]
    Provider --> Tags["Tagged extenders registered"]
    Bridge --> Registrar["AdminBridgeRegistrar"]
    Registrar --> Surface["AdminSurfaceContributionRegistry"]
    Tags --> Resolver["Schema/action/table resolver"]
    Surface --> Panel["CapellAdminPlugin builds Filament panel"]
    Resolver --> Panel
    Panel --> Permission["Policies and permissions"]
    Permission --> Browser["Admin UI renders"]

Most admin bugs are either missing registration, stale cache, wrong tag, or permission denial.

First Checks

php artisan optimize:clear
php artisan capell:admin-clear-cache
php artisan capell:admin-cache-configurators
php artisan capell:admin-cache-widgets
php artisan capell:admin-install

Use only the commands present in php artisan list capell.

Symptom Table

Symptom	Likely cause	Check	Fix
Page/resource missing from navigation	Not registered or permission denied	AdminBridge registration and user permissions	Register through `AdminBridgeRegistrar` and rerun admin install when permissions changed.
Form field missing	Wrong schema extender tag/hook or stale configurator cache	Extender class, `supports()`, and tag constant	Tag with `PageSchemaExtender::TAG`, `SiteSchemaExtender::TAG`, `LayoutSchemaExtender::TAG`, or `UserSchemaExtender::TAG`.
Header action missing	Wrong action extender for the surface	Page/site/resource resolver	Use `PageHeaderActionExtender`, `SiteHeaderActionExtender`, or `ResourceHeaderActionExtender`.
Table query unchanged	Extender modifies the wrong query or returns a new builder incorrectly	`PageTableExtender::modifyQuery()` test	Return the modified builder and cover the query with a fixture.
Extensions page alert missing	Extender not tagged or package unavailable	`ExtensionsPageExtender::TAG` and package state	Tag the extender and force package installed in tests.
Settings tab missing	Settings class/schema/metadata missing	`SettingsSchemaRegistry`	Register settings class, schema, and metadata.
Works for super admin only	Policy/permission missing for role	Role permissions and policy methods	Seed/register package permissions and test allowed/denied roles.

Test Recipes

Bridge Registration

it('registers package admin bridge', function (): void {
    CapellCore::forcePackageInstalled('capell-app/example');

    expect(CapellAdmin::getAdminBridgeRegistry()->classes('capell-app/example'))
        ->toContain(ExampleAdminBridge::class);
});

Schema Extender

it('adds the package field to the page form', function (): void {
    $extenders = collect(app()->tagged(PageSchemaExtender::TAG));

    expect($extenders)
        ->toContain(fn (PageSchemaExtender $extender): bool => $extender instanceof ExamplePageSchemaExtender);
});

Permission Boundary

it('hides the package page from users without permission', function (): void {
    $this->actingAs($editor);

    livewire(ExamplePackagePage::class)
        ->assertForbidden();
});

Rules

Use translations for labels and notifications.
Keep package behavior in Actions; Filament pages should orchestrate.
Test the direct registry/tag where possible, then add one Filament render test for the user-facing surface.
Do not register admin UI from frontend providers.
