Laravel Eloquent ORM Replicated

Question

I have a problem replicating one of my models with all relationships.

The structure of the database is as follows:

Table1: products
id
name

Table2: product_options
id
product_id
option

Table3: categories
id
name

Pivot table: product_categories
product_id
category_id

Relations:

• product hasMany product_options
• the product belongs to any category (trough product_categories)

I would like to clone a product with all relationships. My code is currently located here:

$product = Product::with('options')->find($id);
$new_product = $product->replicate();
$new_product->push();
foreach($product->options as $option){
    $new_option = $option->replicate();
    $new_option->product_id = $new_product->id;
    $new_option->push();
}

But this does not work (the relationship is not cloned - currently I was just trying to clone product_options).

Answer 1

This code worked for me:

$model = User::find($id);

$model->load('invoices');

$newModel = $model->replicate();
$newModel->push();

foreach($model->getRelations() as $relation => $items){
    foreach($items as $item){
        unset($item->id);
        $newModel->{$relation}()->create($item->toArray());
    }
}

The answer is from here: Clone a bright object, including all relationships?

( ) .

//copy attributes from original model
$newRecord = $original->replicate();
// Reset any fields needed to connect to another parent, etc
$newRecord->some_id = $otherParent->id;
//save model before you recreate relations (so it has an id)
$newRecord->push();
//reset relations on EXISTING MODEL (this way you can control which ones will be loaded
$original->relations = [];
//load relations on EXISTING MODEL
$original->load('somerelationship', 'anotherrelationship');
//re-sync the child relationships
$relations = $original->getRelations();
foreach ($relations as $relation) {
    foreach ($relation as $relationRecord) {
        $newRelationship = $relationRecord->replicate();
        $newRelationship->some_parent_id = $newRecord->id;
        $newRelationship->push();
    }
}

Answer 2

attach, :

foreach($product->options as $option){
    $new_option = $option->replicate();
    $new_option->save();
    $new_option_id = $new_option->id;
    $new_product->options()->attach($new_option_id);
}

Answer 3

$product = Product::with('options')->find($id);
$new_product = $product->replicate();
$new_product->{attribute} = {value};
$new_product->push();

$new_product->options()->saveMany($product->options);
