Laravel Getting value of another table using foreign key on Blade - php

Question

I have two models Batch and Notices. The foreign key is correctly formed and data is saved in the database. Now I can't show the data on my listing blade.
Notice Migration:
Schema::create('notices', function (Blueprint $table) {
$table->id();
$table->string('noticeTitle');
$table->string('noticeDesc');
$table->string('file')->nullable();
$table->unsignedBigInteger('batch_id');
$table->foreign('batch_id')->references('id')->on('batches');
$table->timestamps();
});
Batch Migration:
Schema::create('batches', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->timestamps();
});
Data dump from db is:
"id" => 1
"noticeTitle" => "Quae ea est temporib"
"noticeDesc" => "<p>sa</p>"
"file" => null
"batch_id" => 2
"created_at" => "2020-07-27 16:09:52"
"updated_at" => "2020-07-27 16:09:52"
]
Notice model
public function batches()
{
return $this->belongsTo(Batch::class);
}
Batch Model
public function notice()
{
return $this->hasMany(Notice::class);
}
Notice controller
public function index(){
$notices = Notice::all();
return view('admin.notice.list')
->with('notices', $notices);
}
public function store(Request $request)
{
$this->validate($request, [
'noticeTitle' => 'required',
'noticeDesc' => 'required',
]);
$notice = new Notice;
$notice->noticeTitle = $request->input('noticeTitle');
$notice->noticeDesc = $request->input('noticeDesc');
$notice->batch_id = $request->input('targetedGroup');
if($request->hasFile('file')) {
$noticeTitle = $request->input('noticeTitle');
$filename = $request->file->getClientOriginalName();
$request->file->storeAs('public/noticeFile/additionalFiles', $noticeTitle.'_'.$filename);
$path = $noticeTitle.'_'.$filename;
$notice->file = $path;
}
try{
$notice->save();
Session::flash('success', 'Notice Saved');
return redirect()->route('notice.index');
}
catch (\Throwable $th){
Session::flash('danger', 'Something went wrong');
return redirect()->route('notice.index');
}
}
Now I want to get batch name from batch_id

Answer 1

First, you might want to change the function names of your relationships. Your notice has only one batch, so it should be public function batch() and a batch has several notices, so public function notices().
You can acces your relationships like any attribute, so in your blade:
#foreach($notices as $notice)
#php $batch = $notice->batch; #endphp
{{$batch->name}}
#endforeach
Or even shorter (if you don't plan on using the related batch for anything else)
#foreach($notices as $notice)
{{$notice->batch->name}}
#endforeach
This is all explained in the Laravel documentation: https://laravel.com/docs/7.x/eloquent-relationships
