Clone an Eloquent object including all relationships?

Question

Is there any way to easily clone an Eloquent object, including all of its relationships?

For example, if I had these tables:

users ( id, name, email ) roles ( id, name ) user_roles ( user_id, role_id ) 

In addition to creating a new row in the users table, with all columns being the same except id, it should also create a new row in the user_roles table, assigning the same role to the new user.

Something like this:

$user = User::find(1); $new_user = $user->clone(); 

Where the User model has

class User extends Eloquent {     public function roles() {         return $this->hasMany('Role', 'user_roles');     } } 

Answer 1

tested in laravel 4.2 for belongsToMany relationships

if you're in the model:

    //copy attributes     $new = $this->replicate();      //save model before you recreate relations (so it has an id)     $new->push();      //reset relations on EXISTING MODEL (this way you can control which ones will be loaded     $this->relations = [];      //load relations on EXISTING MODEL     $this->load('relation1','relation2');      //re-sync everything     foreach ($this->relations as $relationName => $values){         $new->{$relationName}()->sync($values);     }

You may also try the replicate function provided by eloquent:

http://laravel.com/api/4.2/Illuminate/Database/Eloquent/Model.html#method_replicate

$user = User::find(1); $new_user = $user->replicate(); $new_user->push();
