Regeneration and your code

Changing a resource

1. Edit the descriptor, for example add "featured": { "kind": "boolean" } to fields.
2. Run php artisan nevela:generate.
3. Write a migration for the database change. Nevela does not write one for you after the first: php artisan make:migration add_featured_to_products.
4. Run php artisan migrate.

Your code is kept

Generated code sits between two marker comments:

// nevela:generated:start hash=4f1c2a9b7e31
protected $fillable = ['name', 'sku', 'price'];
// nevela:generated:end

// Your own relationships, scopes and accessors go here.

Regeneration rewrites only what is between the markers. Anything outside them is never touched.

If you edit inside the markers, Nevela notices, because the hash no longer matches the content. It skips that file and tells you:

app/Models/Product.php .. skipped — edited inside generated block

Move your change outside the markers and run the command again, or use --force to overwrite it.

Files marked “written once” above belong to you after they are created. Regeneration never changes them.
