Laravel 5.8：如何在多对多关系中显示数据透视表的列信息

Question

I have a Many To Many relationship between User Model & Wallet Model:

Wallet.php :

public function users() {
    return $this->belongsToMany(User::class,'user_wallet','user_id','wallet_id');
}

And User.php :

public function wallets() {
    return $this->belongsToMany(Wallet::class,'user_wallet','user_id','wallet_id');
}

And the pivot table of this relationship goes like this:

So I can properly show Wallet name at the Blade:

@forelse($user->wallets as $wallet)
    <tr>
        <td>
            {{ $wallet->name }}
        </td>
        <td>
            {{ $wallet->balance }}
        </td>
    </tr>
@empty
    <td colspan="5" class="text-center">
        No wallet exist
    </td>
@endforelse

But the wallet balance data does not appear (because it's in the pivot table and not the wallets table).

So how to show this custom column in this case?

Answer 1

use withPivot and mention additional column name

public function wallets()
{
    return $this->belongsToMany(Wallet::class,'user_wallet','user_id','wallet_id')->withPivot('balance');
}

then in view

  <td>{{ $wallet->pivot->balance }}</td>
