show all subjects offered by a student using laravel eloquent - laravel

I have done one-to-many relationships but when I loop through it in my view only one subject displays even when I have more than one subjects.
This is what I have done in my controller
$broadsheet = Broadsheet::with(['subject', 'session', 'term', 'student', 'classarm'])
->where('session_id', $request->sessions)
->where('term_id', $request->terms)
->where('class_arm_id', $request->classarms)
->selectRaw('sum(total) as totals, count(subject_id) as countrow, student_id, subject_id, session_id, term_id, class_arm_id, total')
->groupBy('student_id')
->orderBy('totals', 'desc')
->get();
return view('broadsheet.index')->with('broadsheet', $broadsheet);
This is the index view
#extends('layouts.app')
#section('content')
{{--#foreach($broadsheet as $subjects)
#foreach ($subjects->subject as $sub)
<th> {{ strtoupper($sub->subject->subject_name) }}</th>
#endforeach
#endforeach--}}
<div class="table-responsive">
<table class="table table-striped table-sm">
<thead>
<tr>
#foreach($broadsheet as $subject)
<th> {{ strtoupper($subject->subject->subject_name) }}</th>
#endforeach
<th>TOTAL</th>
<th>AVERAGE</th>
<th>POSITION</th>
</tr>
</thead>
<tbody>
#foreach($broadsheet as $result)
<tr>
<td>{{ $result->total }}</td>
<td>{{ $result->totals }}</td>
<td>{{ number_format($result->totals/$result->countrow,2) }}</td>
<td>{{ $i++ }}</td>
<td>{{ $result->exams }}</td>
<td>{{ $result->total }}</td>
</tr>
#endforeach
</tbody>
</table>
</div>
#endsection
and this is my Broadsheet schema
class Broadsheet extends Model
{
use HasFactory;
protected $fillable = [
'student_id',
'subject_id',
'session_id',
'term_id',
'class_arm_id',
'subject_total',
];
public function student()
{
return $this->belongsTo(Student::class, 'student_id');
}
public function subject()
{
return $this->belongsTo(Subject::class, 'subject_id');
}
public function session()
{
return $this->belongsTo(Session::class, 'session_id');
}
public function term()
{
return $this->belongsTo(Term::class, 'term_id');
}
public function classarm()
{
return $this->belongsTo(ClassArm::class, 'class_arm_id');
}
}

Data for foreach loop returning empty yet there is data in the table laravel 8

i want to display a product with all its attributes in a page.i am using for each loop to display the data using a variable I have defined in the relationship.the problem is after fetching the data its unable to display the data on the browser.i havent understood where i have gone wrong..kindly assist.
the method in the controller
public function show($id)
{
$merchadisedata=Merchadise::find($id);
return view('backend.merchadise.productattributes')->with(compact('merchadisedata'));
}
the variable in the product model that defines the relationship,i have imported the productattributemodel class at the top
public function merchadiseattributes()
{
return $this->hasMany(Productattribute::class);
}
the foreach loop in the blade file that show the data
<table id="admindatatables" class="table table-bordered display nowrap" width="100%">
<thead class="thead-dark">
<tr>
<th>Product Name </th>
<th>Attribute Size</th>
<th>Attribute Stock</th>
<th>Attribute Price</th>
<th>Attribute Sku</th>
<th>Attribute Status</th>
</thead>
<tbody>
#foreach ( $merchadisedata->merchadiseattributes as $attribute)
<tr>
<td>{{ $attribute->merchads->merch_name }}</td>
<td>{{ $attribute->productattr_size}}</td>
<td>{{ $attribute->productattr_stock }}</td>
<td>{{ $attribute->productattr_price}}</td>
<td>{{ $attribute->productattr_sku }}</td>
<td>{{ $attribute->productattr_status}}</td>
</tr>
#endforeach
</tbody>
</table>
The problem what you have is that Laravel cant find the relation because the index name from your Productattribute table is not id. it is product_id.
Then you have declare in the model the new index name like that:
return $this->hasMany(Productattribute::class, 'foreign_key', 'local_key'); means:
public function merchadiseattributes()
{
return $this->hasMany(Productattribute::class, 'product_id', 'id');
}

how to retrieve one to many relationship. Property [produks] does not exist on this collection instance

Operator Model
public function produk()
{
return this->hasMany(Produk::class);
}
Produk Model
public function operator()
{
return this->belongsTo(Operator::class);
}
Controller
public function operator()
{
$data = Operator::all();
return view('data', compact('data'));
}
View
#foreach ($data as $o)
<tr>
<td>{{ $loop->iteration }}</td>
<td>{{ $o->n_oper }}</td>
<td>
#foreach ($data->produk as $p)
{{ $p->n_prod }}
#endforeach
</td>
</tr>
#endforeach
Output
Exception
Property [produk] does not exist on this collection instance. (View: C:\xampp\htdocs\laravel\oni\resources\views\data.blade.php)
what went wrong? please kindly assist me, im new to this
this is a typo may be?? whatever, you are calling relationship on collection. relation belongs to an object.
#foreach ($data as $o)
<tr>
<td>{{ $loop->iteration }}</td>
<td>{{ $o->n_oper }}</td>
<td>
#foreach ($o->produk as $p)
{{ $p->n_prod }}
#endforeach
</td>
</tr>
#endforeach
data is the collection. you have to call relationship on $o
and there's some other typos may be. you are missing the $ sign in $this keyword. update your relationship
public function produk()
{
return $this->hasMany(Produk::class);
}
and
public function operator()
{
return $this->belongsTo(Operator::class);
}
You are calling relation on collection. You have to call it on single instance like this
#foreach ($data as $o)
<tr>
<td>{{ $loop->iteration }}</td>
<td>{{ $o->n_oper }}</td>
<td>
#foreach ($o->produk as $p)
{{$p->n_prod}}
#endforeach
</td>
</tr>
#endforeach
And also change
return this->hasMany(Produk::class);
this to
return $this->hasMany(Produk::class);
and also for other relation like
return this->belongsTo(Operator::class);
to
return $this->belongsTo(Operator::class);
I hope its work.

You are trying to print your object values as an array.You need to update your code with this, access your object values like this way

Laravel: Undefined variable

im having a problem with my code.
I want to show the record of the student who login but im having an
undefined variable on my view.blade
Here's my Model
class Attendance extends Eloquent {
public function users()
{
return $this->belongsTo('User', 'id');
}
}
Here's my Controller
public function viewstudentAttendance()
{
$students = Auth::user()->id;
//load view and pass users
return View::make('student.view')
->with('attendances', $students);
}
Finally here's my view.blade
#extends('layouts.master')
#section('head')
#parent
<title>View Attendance</title>
#stop
{{ HTML::style('css/bootstrap.css'); }}
#section('content')
</ul>
#if ($students->count())
<table class="table table-striped table-bordered">
<thead>
<tr>
<th>ID</th>
<th>First name</th>
<th>Last name</th>
</tr>
</thead>
<tbody>
#foreach ($students as $students)
<tr>
<td>{{ $students->id }}</td>
<td>{{ $students->firstname }}</td>
<td>{{ $students->lastname }}</td>
#endforeach
</tr>
{{ HTML::script('js/bootstrap.js'); }}
</tbody>
</table>
#else
There are no attendance recorded yet
#endif
#stop
I think the problem is with my view or how i declare the variable? Please help? :(
public function viewstudentAttendance() {
//This code turns ID ONLY Check the website out for a code that retrieves data so you can loop it.
$students = Auth::user() - > id;
//Code that counts number of student
$studentCount = XXX(Google It)
//load view and pass users
return View::make('student.view') - > with('attendances', $students);
//Return StudentCount too
}
Inside your blade template, use :
#if ($studentCount > 10)
instead of
#if ($students->count())
Your students is returning ID, how could you "Count"
http://laravel.com/docs/4.2/eloquent
Inside your blade you kept doing if($students) bla bla, just to let you know it's attendances
->with('attendances', $students);
Attendances is the variable your blade will see, $student is the data you are pushing into attendances for blade
