Add own-vs-any authorization to a new resource

Worked example: giving SavedFilter the same "you can always manage your own, but need a broader permission to manage anyone else's" shape Comment already has — closing the gap ../saved-filters/README.md flags (today, any project member can delete any saved filter, with no ownership distinction at all).

The pattern, as CommentPolicy already establishes it

File: app/Policies/CommentPolicy.php

private const array OWN_TIERS = [RoleType::OWNER, RoleType::ADMIN, RoleType::MEMBER];

private const array ANY_TIERS = [RoleType::OWNER, RoleType::ADMIN];

public function update(User $user, Comment $comment): bool
{
    $project = $comment->issue->project;

    if ($comment->user_id === $user->id) {
        return $project->hasPermissionOrTier($user, Permission::COMMENTS_UPDATE_OWN, self::OWN_TIERS);
    }

    return $project->hasPermissionOrTier($user, Permission::COMMENTS_UPDATE_ANY, self::ANY_TIERS);
}

The shape is always the same: check who owns the resource first, then branch to one of two separate permissions — a *_own one with a wider tier allow-list (every tier that can act at all) and a *_any one with a narrower one (only tiers trusted to touch other people's things) — never a single permission with an ownership check bolted on inline. This is what lets a custom role grant "edit your own comments" without also granting "edit anyone's."

Step 1 — Add an owner column

New migration:

Schema::table('saved_filters', function (Blueprint $table) {
    $table->foreignId('user_id')->nullable()->after('project_id')->constrained()->nullOnDelete();
});

Nullable, so existing rows created before this change don't need a backfill to remain valid — an "unowned" saved filter simply never matches the "own" branch below and always falls through to the _any check.

Step 2 — Add the two permissions

Following 01-add-a-new-permission.md's pattern exactly:

// app/Enums/Permissions/Permission.php
case SAVED_FILTERS_DELETE_OWN = 'saved_filters.delete_own';
case SAVED_FILTERS_DELETE_ANY = 'saved_filters.delete_any';

// app/Services/RoleService.php
private const array MEMBER_DEFAULT_PERMISSIONS = [
    // ...existing entries...
    Permission::SAVED_FILTERS_DELETE_OWN,
];

Only _OWN goes into MEMBER_DEFAULT_PERMISSIONS (Viewer gets neither, matching its read-only default posture) — _ANY is deliberately left out of every non-Owner/Admin default, exactly the comment permissions' precedent.

Step 3 — Write the Policy

New file: app/Policies/SavedFilterPolicy.php

<?php

namespace App\Policies;

use App\Enums\Permissions\Permission;
use App\Enums\Permissions\RoleType;
use App\Models\SavedFilter;
use App\Models\User;

class SavedFilterPolicy
{
    private const array OWN_TIERS = [RoleType::OWNER, RoleType::ADMIN, RoleType::MEMBER];

    private const array ANY_TIERS = [RoleType::OWNER, RoleType::ADMIN];

    public function delete(User $user, SavedFilter $savedFilter): bool
    {
        $project = $savedFilter->project;

        if ($savedFilter->user_id === $user->id) {
            return $project->hasPermissionOrTier($user, Permission::SAVED_FILTERS_DELETE_OWN, self::OWN_TIERS);
        }

        return $project->hasPermissionOrTier($user, Permission::SAVED_FILTERS_DELETE_ANY, self::ANY_TIERS);
    }
}

File: app/Http/Controllers/SavedFilterController.php

public function destroy(SavedFilter $savedFilter): RedirectResponse
{
    $this->authorize('delete', $savedFilter);

    $this->savedFilterService->delete($savedFilter);

    return redirect()->back()->with('success', 'Saved filters has been deleted successfully.');
}

replacing the old $this->authorize('view', $savedFilter->project) — this is why the pattern belongs in a dedicated Policy method rather than inline in the Controller: authorize('delete', $savedFilter) resolves to SavedFilterPolicy::delete automatically (Laravel's Policy auto-discovery, keyed on the model class), no explicit registration needed, same as every other Policy in this codebase.

Step 4 — Store the owner on create

File: app/Services/SavedFilterService.php (see ../saved-filters/01-extract-the-service-layer.md if this doesn't exist yet in your checkout)

public function create(Project $project, array $data): SavedFilter
{
    $filter = $this->savedFilterRepository->create([
        ...$data,
        'user_id' => auth()->id(),
    ]);

    $this->activityLogService->log($project->id, "Saved a new filter: \"{$filter->name}\"");

    return $filter;
}

Step 5 — Expose it to the frontend, if the UI needs to know

Following the same convention 01-add-a-new-permission.md's step 4 uses — compute the boolean directly off the model/Gate for a UI-facing prop, the same way Comment does it as a model-appended attribute rather than a Controller-computed one:

// app/Models/SavedFilter.php
protected $appends = ['can_delete'];

public function getCanDeleteAttribute(): bool
{
    return auth()->check() && Gate::forUser(auth()->user())->allows('delete', $this);
}

Add use Illuminate\Support\Facades\Gate; to the model's imports. Reach for this model-appended-attribute shape (rather than computing the boolean in the Controller and threading it through as a separate prop, the way SettingsController does for canUpdateIntegrations) specifically when the resource is already serialized as a list of model instances sent straight to the frontend — can_delete then travels for free with every filter in the array, with no separate parallel array of ids-that-are-deletable to keep in sync.

Tests

• tests/Feature/SavedFilterControllerTest.php — add "the owner can delete their own saved filter", "a non-owner member without saved_filters.delete_any cannot delete someone else's filter", and "an admin can delete any member's saved filter", mirroring tests/Feature/CommentControllerTest.php's own/any test shapes exactly.
• tests/Feature/Models/SavedFilterTest.php — add a test asserting can_delete reflects the Policy decision for both the owner and a non-owner, mirroring tests/Feature/Models/CommentTest.php's can_edit/can_delete coverage.
• tests/Feature/RoleServiceTest.php — update the exact permission-id-set assertions for Member/Viewer defaults to include the two new cases, the same update 01-add-a-new-permission.md's own tests section calls out.
