链接视图和控制器时出现问题

Question

This is the error I am getting on the sample view:

Undefined variable: sampleRecord

This is the controller code:

 public function show($sample_id)
 {
    return View::make('samples.show')->with([
        $this->sampleRepository->find($sample_id),
        $this->sampleRecord->getSamplePartNumberRecord,
    ]);
 }

This is the view code:

<p>{{ $sampleRecord }}</p>

@foreach($sampleRecord->SamplePartNumbers() as $samplePartNumberRecord)
<p>Sample Part Number: <br />{{ $samplePartNumberRecord }}</p>
@endforeach

Answer 1

your controller should be:

public function show($sample_id)
{
    return View::make('samples.show')->with([
        "sampleRepository" => $this->sampleRepository->find($sample_id),
        "sampleRecord" => $this->sampleRecord->getSamplePartNumberRecord,
    ]);
 }
