[Route: roles.destroy] 缺少必需的参数

Question

我发现了这个错误 [Route: roles.destroy] [URI: roles/{role}] 缺少必需的参数。 （查看：E:\wamp64\www\student_system\resources\views\roles\table.blade.php）

<div class="table-responsive">
<table class="table" id="roles-table">
    <thead>
        <tr>
            <th>Name</th>
            <th colspan="3">Action</th>
        </tr>
    </thead>
    <tbody>
    @foreach($roles as $role)
        <tr>
            <td>{{ $role->name }}</td>
            <td>
                {!! Form::open(['route' => ['roles.destroy', $role->id], 'method' => 'delete']) !!}
                <div class='btn-group'>
                    <a href="{{ route('roles.show', [$role->id]) }}" class='btn btn-default btn-xs'><i class="glyphicon glyphicon-eye-open"></i></a>
                    <a href="{{ route('roles.edit', [$role->id]) }}" class='btn btn-default btn-xs'><i class="glyphicon glyphicon-edit"></i></a>
                    {!! Form::button('<i class="glyphicon glyphicon-trash"></i>', ['type' => 'submit', 'class' => 'btn btn-danger btn-xs', 'onclick' => "return confirm('Are you sure?')"]) !!}
                </div>
                {!! Form::close() !!}
            </td>
        </tr>
    @endforeach
    </tbody>
</table>

Answer 1

我从未使用过 Form 类，但我认为您可以尝试只传入 $role。
