Laravel eloquent delete - laravel

Question

I am looking for some assistance on how to understand Laravel Eloquent model.
I need to delete User by Id, and I have tables Main_info, Personal_info, Holidays, other_info, fm_day, oth_daysoff.
On the tables, I have inserted UserId field, so I need to delete selected UserId from all of the tables? May someone help me on how I can do this with Laravel Eloquent model?
Here is my view with delete submit button and post method:
<div class="container">
<div class="row">
<div class="col">
<div class="card">
<div class="card-head-man">
<span>Filter type: </span>
Position
Active/No
Employment type
Location
</div>
</div>
</div>
<div class="col-12">
<div class="card">
<div class="card-header">
<h3 class="card-title">List of employees</h3>
</div>
<div class="table-responsive">
<table class="table card-table table-vcenter text-nowrap">
<thead>
<tr>
<th class="w-1">ID<span class="caret"></span></th>
<th>First Name<span class="caret"></span></th>
<th>Last Name</th>
<th>Position</th>
<th>Active/no</th>
<th>Employment type</th>
<th>Location</th>
<th></th>
<th></th>
</tr>
</thead>
<tbody>
#foreach($allData as $data)
<tr>
<td><span class="text-muted">{{ $data->id }}</span></td>
<td>{{ $data->first_name }}</td>
<td>
{{ $data->last_name }}
</td>
<td>
{{ $data->position }}
</td>
<td>
{{ $data->employment_type }}
</td>
<td>
<span class="status-icon bg-success"></span> Active
<span class="status-icon bg-danger"></span> No
</td>
<td>{{ $data->location }}</td>
<td class="text-right">
Manage
<div class="dropdown">
<form action="/deleteFromHome" method="post">
{{csrf_field()}}
<input style="display: none;" type="text" name="deleteUserId" class="form-control" id="inputName3" value="{{ $data->id }}">
<button type="submit" class="btn btn-secondary btn-sm">Delete</button>
</form>
</div>
</td>
<td>
<a class="icon" href="javascript:void(0)">
<i class="fe fe-edit"></i>
</a>
</td>
</tr>
#endforeach
</tbody>
</table>
</div>
</div>
</div>
Here is how my controller doing it now:
public function deleteUserFromHome(Request $req)
{
$userId = $req->input('deleteUserId');
OtherInfo::where('id', $userId)->delete();
OthDaysInfo::where('id', $userId)->delete();
HolidaysInfo::where('id', $userId)->delete();
FMdaysInfo::where('id', $userId)->delete();
PersonalInfo::where('id', $userId)->delete();
PersonalInfo::where('id', $userId)->delete();
MainInfo::where('id', $userId)->delete();
return redirect('home');
}
Maybe there is some better way to delete all data from all tables about selected userId?
I need some example how I can make Laravel Eloquent model to delete with function HasMany or some else?

You can use ->onDelete('cascade')when you create your table migrations.
For instance,
// consider a sample migration below for a table with a foreign key on your users table
Schema::create('main_info', function (Blueprint $table) {
$table->increments('id');
$table->integer('user_id');
$table->foreign('user_id')
->references('id')
->on('users')
->onDelete('cascade');
$table->timestamps();
});
And then you can easily just delete the specified user, and Laravel will take care of deleting it's child records.
$user = User::find($id);
$user->delete(); // this will also delete any record for this user on main_info table
