Laravel - Edit product with polymorphic relation - php

Question

I have a system where to user needs to be able to change a product. But the problem is, This product has a polymoprhic relation with theme. This is the build-up
Products
- ID
- productable_id (For instance "1")
- productable_type (Is either "App\Theme"or "App\Plugin")
- name (Just a name)
- description (Just a description)
- etc
Theme
- id (1)
- composer_package
Now I need the user to be able to change a product. Currently, I have it done like this in the controller
public function update(Request $request, $id)
{
$product = Product::find($id);
$product->fill($request->all());
$product->save();
return redirect('/products')->with('flash', $product->name . ' is succesvol bewerkt');
}
But since its a polymorphic relation I don't know how to change for example the "composer_package" that is associated with the selected product. Say, for instance, I want to change the product with the ID of 1. Then I want to also be able to change the composer_package with the id 1 because that one is associated with that selected product. Also, How can I change for instance, the type of product. The selected product is an App\Theme and I want to change that to App\Plugin. How can I achieve the above two things with this polymorphic relation
This is the form that is collecting the data. It's quite large
<div class="modal fade-scale" id="createProduct" tabindex="-1" role="dialog" aria-labelledby="IetsAnders" aria-hidden="true">

EDIT
Product model
class Product extends Model
{
protected $fillable = [
'productable_type', 'productable_id', 'name', 'description', 'thumbnail', 'price', 'periodically_price', 'period_id'
];
public function productable()
{
return $this->morphTo();
}
public function order_items()
{
return $this->hasMany(Orderitems::class);
}
public function plan() {
return $this->belongsTo(Plan::class, 'period_id');
}
}
Theme Model
class Theme extends Model
{
protected $fillable = [
];
public function webshops()
{
return $this->hasMany(Webshop::class);
}
public function products()
{
return $this->morphMany(Product::class, 'productable');
}
}

Answer 1

Add composer_package to Theme::$fillable.
Adjust the HTML form: name="productable[composer_package]"
Then you can update the theme like this:
$product->productable->update($request->get('productable'))
