Laravel访问刀片中的外键表列

Question

How can I access a table column using a foreign key in blade so far I have this but it does not work.

Inquiry Model / relations

public function client()
{
    return $this->belongsTo(Client::class);
}
public function device()
{
    return $this->belongsTo(Device::class);
}

Client Model

public function inquiry()
{
    return $this->hasMany(Inquiry::class);
}
public function devices()
{
    return $this->hasMany(Device::class);
}

Device Model

public function inquiry()
{
    return $this->hasMany(Inquiry::class);
}

Controller

public function index()
{
    $inquiries = Inquiry::all();
    return view('stream.index', compact('inquiries'));
}

View

@foreach($inquiries as $inquiryKey => $inquiryValue)
    <tr>
        // stream id is the foreign that table has a column with names ...
        <th scope="row">{{ $inquiryValue->stream_id }}</th>        // works
        <th scope="row">{{ $inquiryValue->stream_id->name }}</th>  // does not work -> trying to get property of none object

Answer 1

You cannot access attribute name of stream_id , it's just an integer, what you may try is $inquiryValue->client->name or i think, $inquiryValue->client->first()->name

Be sure to let Laravel know that stream_id is the key used for your relations.

Answer 2

You should try with this example like :

Updated answer

Controller

public function index()
{
    $inquiries = Inquiry::all();
    return view('stream.index', compact('inquiries'));
}

View file

@foreach($inquiries as $inquiryKey => $inquiryValue)
    <tr>
        // stream id is the foreign that table has a column with names ...
        <th scope="row">{{ $inquiryValue->client->name }}</th>        // works
    </tr
@endforeach

Answer 3

if you name it stream_id than i think it's better u have a table name streams , if u want to get the client data from inquiry, than u should have client_id column in your inquiry table, same for the device, add device_id column to your inquiry table

How to access it: @foreach($inquiries as $inquiryKey => $inquiryValue) {{$inquiryValue->client->name}} {{$inquiryValue->device->name}} @endforeach
