Laravel get related models of related models

Thursday, July 3, 2014

I have a RepairRequest model, which is associated with a Vehicle.

class RepairRequest extends \Eloquent {
public function vehicle() {
return $this->belongsTo('Vehicle');

class Vehicle extends \Eloquent {
public function requests() {
return $this->hasMany('RepairRequest');

I would like to get all RepairRequests for the vehicle associated with a given RepairRequest, so I do

return RepairRequests::find($id)->vehicle->requests;

This works fine.

However, RepairRequests have RepairItems:

// RepairRequest class
public function repairItems() {
return $this->hasMany('RepairItem', 'request_id');

// RepairItem class
public function request() {
return $this->belongsTo('RepairRequest', 'request_id');

which I would like to return too, so I do

return RepairRequests::find($id)->vehicle->requests->with('repairItems');

but I get the following exception:

Call to undefined method Illuminate\Database\Eloquent\Collection::with()

How can I write this so that the returned json includes the RepairItems in the RepairRequest json?
