Filter DB Records by Active Tenant

Now, let's filter the records by my current team. For that, we will add tenant_id column to all the DB tables that should be "tenantable". We create a Trait, and this will be a lesson about Traits and Scopes, similar like we had in one earlier lesson.

So, let's generate two migrations to add tenant_id to projects and tasks tables.

php artisan make:migration "add tenant id to projects table"
php artisan make:migration "add tenant id to tasks table"

database/migrations/xxx_add_tenant_id_to_projects_table.php:

Schema::table('projects', function (Blueprint $table) {
    $table->foreignId('tenant_id')->constrained();
});

database/migrations/xxx_add_tenant_id_to_tasks_table.php:

Schema::table('tasks', function (Blueprint $table) {
    $table->foreignId('tenant_id')->constrained();
});

Now, let's create a trait, FilterByTenant.

php artisan make:trait Traits/FilterByTenant

We will use the same booted() method for...
