将模型集合转换为id为key的数组

Question

I am using Laravel HTML component to create a dropdown to list all the groups to which an user can belong.

The list of groups comes from a Groups table.

Currently in my controller my code looks like

    $groups = array();
    $groupModels = Group::all(['id', 'name']);

    foreach ($groupModels as $groupModel) {
        $groups[$groupModel->id] = $groupModel->name;
    }

    return view('myview', compact('groups'));

and in my view I have the following code to create the dropdown

    {!! Form::select('group', $groups, null, ['class' => 'form-control']) !!}

This works, but I am trying to see if there is a way to avoid the foreach loop and directly convert the list of Models into an array. Is it possible?

Answer 1

Use pluck() method:

$groups = Group::pluck('name', 'id');
return view('myview', compact('groups'));
