在Laravel中设置正确的选项值

Question

can anyone help me set the option variables on a select style drop-down in Laravel 5.1?

In my controller I have

$buildings = Warf::select('facilityname')
    ->distinct()
    ->get();
.
.
.
return view('reports.space', compact('buildings');

the 'space' view looks like

{!! Form::open() !!}
<div class="well col-sm-6 col-sm-offset-3">

   <legend>Spacial Reports</legend>

            <div class="form-group">
                {!! Form::label('building_', 'Building:') !!}
                {!! Form::select('building', $buildings, null, ['class' => 'form-control'])!!}
            </div>
.
.
.

            <div class="form-group">
                {!! Form::submit('Submit', ['class' => 'btn btn-primary form-control']) !!}
            </div>

</div>
{!! Form::close() !!}

However this results in the following HTML

<div class="form-group">
    <label for="building_">Building:</label>
    <select class="form-control" name="building"><option value="0">{"facilityname":"WARF"}</option></select>
</div>

Questions: A) How can I get just "WARF" to show up in the dropdown? B) Is there a way to default the selection to show no values?

Thanks, Otterman

I am using the Collective Html generator if that makes a difference

Answer 1

Try selecting the column as "name"

$buildings = Warf::select('facilityname as name')
->distinct()
->get();

or you might need to return that using lists, something like:

$buildings = Warf::select('facilityname as name')
->distinct()
->lists('name','id')->all() //
