storing data with name of author - laravel 5.2 - laravel

Question

I have hasMany relation to my model user and reports.
I want to set author name for the reports. (Like a blog-post author)
my model User:
public function reports() {
return $this->hasMany('App\Report', 'author_id');
}
model Report
public function user() {
return $this->belongsTo('App\User', 'author_id');
}
and my controller:
public function create()
{
$category = Category::lists('title','id');
return view('dash.reports.create')->with('category', $category);
}
/**
* Store a newly created resource in storage.
*
* #return void
*/
public function store(Request $request)
{
$this->validate($request, ['title' => 'required', ]);
Report::create($request->all());
Session::flash('flash_message', 'Report added!');
return redirect('dash/reports');
}
I'm able to set in in phpmyadmin, but how can i set it with my controller?
edit: my view:
{!! Form::open(['url' => '/dash/reports', 'class' => 'form-horizontal']) !!}
<div class="form-group {{ $errors->has('title') ? 'has-error' : ''}}">
{!! Form::label('title', 'Servizio', ['class' => 'col-sm-3 control-label']) !!}
<div class="col-sm-6">
{!! Form::text('title', null, ['class' => 'form-control', 'required' => 'required']) !!}
{!! $errors->first('title', '<p class="help-block">:message</p>') !!}
</div>
</div>
<div class="form-group {{ $errors->has('title') ? 'has-error' : ''}}">
{!! Form::label('date', 'Data lavorativa', ['class' => 'col-sm-3 control-label']) !!}
<div class="col-sm-2">
{!! Form::selectRange('day', 1, 31, null, ['class' => 'form-control']) !!}
{!! $errors->first('day', '<p class="help-block">:message</p>') !!}
</div>
<div class="col-sm-2">
{!! Form::selectMonth('month', null, ['class' => 'form-control']) !!}
{!! $errors->first('month', '<p class="help-block">:message</p>') !!}
</div>
<div class="col-sm-2">
{!! Form::select('year', array('2016' => '2016', '2015' => '2015'), null, ['class' => 'form-control']) !!}
{!! $errors->first('year', '<p class="help-block">:message</p>') !!}
</div>
</div>
<div class="form-group {{ $errors->has('category_id') ? 'has-error' : ''}}">
{!! Form::label('category_id', 'Cliente', ['class' => 'col-sm-3 control-label']) !!}
<div class="col-sm-6">
{!! Form::select('category_id', $category, null, ['class' => 'form-control'] ) !!}
{!! $errors->first('category_id', '<p class="help-block">:message</p>') !!}
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-3 col-sm-3">
{!! Form::submit('Create', ['class' => 'btn btn-primary form-control']) !!}
</div>
</div>
{!! Form::close() !!}

Answer 1

Very easy. Replace Report::create... with this.
$user = Auth::user();
$report = new Report($request->all());
$report->author()->associate($user);
$report->save();
Make sure you use Auth; up at the top.
This uses the Auth object to get the current user,
Builds a new Report using the $request data without saving,
Tells the report we're associating $user as the author for the model,
Saves the report with the authorship information.

Answer 2

solution:
public function store(Request $request)
{
$this->validate($request, ['title' => 'required', ]);
$user = Auth::user()->id;
$report = new Report($request->all());
$report->author_id = $user;
$report->save();
Session::flash('flash_message', 'Report added!');
return redirect('dash/reports');
}
