}
View:
<div class="plan bg-plan">
{!! Form::model($datums,['method' => 'PATCH','action'=>'RatingDataController#update'],$datums->id]) !!}
<div class="radio">
<label>
{!! Form::radio('customize_question_id')!!}{{$datums->value}}
</label>
</div>
<div class="form-group">
{!! Form::label('comment','Comment :') !!}
{!! Form::textarea('comment' ,null,['class'=>'form-control', 'rows' => 4]) !!}
{!! Form::label('reference','Reference:') !!}
{!! Form::textarea('reference',null,['class'=>'form-control', 'rows' => 1]) !!}
</div>
{!! Form::submit('Submit Data', ['class' => 'btn btn-success submit']) !!}

Answer 1

The data is not showing up in the form is because you are referencing the wrong variable.
You are passing $datum and in the view form, you are accessing $datums. That is the reason why your form is empty.
Solution:
Do either of the following:
Update controller method's $datum to $datums
OR
Update form model $datums to $datum
