I have two simple one to many relationship tables of medicines and bills. as it happens, many medicines are bought by a single bill.
Now I have a page to show all the bills in each row of a table. Also, I want to be able to view all the sold medicines related to each bill by clicking on the respective bill and the medicines will show up below the row using JQuery.
This is my view code to depict all the bills in a table:
<tbody>
#foreach($bills as $bill)
<tr role="row" class="odd">
<td class="v-align-middle semi-bold">{{$bill->id}}</td>
<td class="v-align-middle semi-bold">{{$bill->customername}}</td>
<td class="v-align-middle">{{$bill->paid}}</td>
<td class="v-align-middle">{{$bill->remainders}}</td>
<td class="v-align-middle">{{$bill->total}}</td>
<td class="v-align-middle">{{$bill->created_at}}</td>
</tr>
#endforeach
</tbody>
and my controller code is:
public function index()
{
$bill = Billpc::all();
return view('bills')->with('bills', $bill);
}
Can anyone help me with how to show all the sold medicines related to the respective bill?
add relationships in your model
Bill model
public function medicines()
{
return $this->hasMany('App\Submission');
}
Medicine model:
public function bill()
{
return $this->belongsTo('App\AssignSubmission');
}
then change your code in your controller. use with to get the medicines in your bill
Controller
public function index()
{
$bill = Billpc::with('medicines')->get();
return view('bills')->with('bills', $bill);
}

A Teacher has many Students. When I am showing the Teachers list I also want to show the counts of Student for each Teachers. How can I do this by using Eloquent?
I can find the Teachers from this,
$teacher= Teacher::where('teacher_status','active')->get();
I can find the Student count from this
$student_count = Student::where('teacher_id','teachers.id')->count();
How can I conbine this two query and return the response in a single array/collection?
In your teacher model, create the relationship students:
class Teacher extends Model
{
public function students()
{
return $this->hasMany(Student::class, 'teacher_id');
}
}
In your controller you can do the following:
public function example(){
$teachers = Teacher::where('teacher_status','active')->withCount('students')->get();
return view('teacherViewExample', compact('teachers'));
}
In your view (teacherViewExample):
<table>
<thead>
<tr>
<th>Teacher Name</th>
<th>Students Count</th>
</tr>
</thead>
<tbody>
#foreach($teachers as $teacher)
<tr>
<td>{{ $teacher->name }}</td>
<td>{{ $teacher->students_count }}</td>
</tr>
#endforeach
</tbody>
</table>
Full documentation on how to use withCount() here: https://laravel.com/docs/9.x/eloquent-relationships#counting-related-models
Sometimes you may want to count the number of related models for a
given relationship without actually loading the models. To accomplish
this, you may use the withCount method. The withCount method will
place a {relation}_count attribute on the resulting models:
If you want to count the number of students related to teacher without actually loading them you may use the withCount method and this add new propery named by a {relation}_count column on your resulting models. For example:
Teacher::where('teacher_status','active')->withCount('students')->get();
Also you need and to your Teacher model hasMany relation method to Students
In case frontend and backend are separated, i.e Laravel for backend, Angular for frontend, below are examples for Laravel:
In api.php,
Route::get('teacher-with-students-count', 'TeacherController#getTeacherWithStudentsCount');
In Teacher.php (model)
class Teacher extends Model
{
public function students()
{
return $this->hasMany(Student::class, 'teacher_id', 'id');
}
}
In TeacherController.php
public function getTeacherWithStudentsCount()
{
$teachers = Teacher::where('teacher_status','active')->withCount('students')->get();
return $this->giveSuccessResponse($teachers);
}
I am working on applying many to many relations on table Accident, Car where the relations are as follows:
In the Accident model:
public function car()
{
return $this->belongsToMany(Car::class,'accident_participateds',
'reportNo','vehicleId');
}
In-car Model
public function accidents()
{
return $this->belongsToMany(Accident::class,'accident_participateds',
'vehicleId','reportNo')->withPivot(['damageAmount', 'IBAN']);
}
I want to display the data from all 3 Models (Car, Accident,accident_participateds)My question is whether these statements are correct in the controller
public function AdminClaims()
{
$claim = Accident::with('car')->get();
$details = Car::with('accidentsr')->get();
return view('admin.AdminClaims',compact('claim','details'));
}
Because when I try to display like this:
<tbody>
#foreach($claim as $claims)
<tr>
<td>{{$claims->ReportNumber}}</td>
#foreach($details as $AP)
<td>{{$AP->vehicleId}}</td>
<td>{{$AP->Location}}</td>
<td>{{$AP->Date}}</td>
<td>{{$AP->damageAmount}}</td>
<td>{{$AP->IBAN}}</td>
#endforeach
</tr>
#endforeach
it print only ReportNumber
kindly tell me where I made a mistake?
From what I understand, you want to display the details of Accident(claim), associated Car and data from the pivot table.
To do so you can try
public function AdminClaims()
{
$claims = Car::with('accidents')->get();
return view('admin.AdminClaims',compact('claims'));
}
And in view
#foreach($claims as $claim)
<tr>
<td>{{$claim->ReportNumber}}</td>
<td>{{$claim->vehicleId}}</td>
<td>{{$claim->Location}}</td>
<td>{{$claim->Date}}</td>
<td>{{$claim->pivot->damageAmount}}</td>
<td>{{$claim->pivot->IBAN}}</td>
</tr>
#endforeach
For the table Exam I have this:
--id----section_id
--1----- 2,3
when I use this in Exam.php Model:
public function Sections(){
return $this->belongsTo(Section::class, 'section_id');
}
It only shows and take in consideration the section_id=2 but not both of the IDS.
How I can get Info from both Ids ?
in the blade.php :
#foreach ($Exams as $exams)
<tr>
<td>{{$exams->id}}</td>
<td>{{$exams->Sections}}</td>
</tr>
#endforeach
I have a potentially basic problem for Eloquent. I want to show only the name corresponding with Role of that user. I used the Eloquent Relationship ManytoMany. But I can't get that to work.
I tried point to the name using the $users parameter but this didn't work.
My project has three files such as Role model, StudentController, find_username view.
Thank you.
Role Model:
class Role extends Model
{
protected $fillable = ['id','role_name','role_level','role_note'];
public function users()
{
return $this->belongsToMany('App\User', 'role_users', 'user_id', 'role_id');
}
}
My StudentController:
class StudentController extends Controller
{
public function find_username()
{
$roles = Role::all();
foreach($roles as $role)
{
echo $role->users . '<br>';
}
return view('find_username',['roles'=> $roles]);
}
}
My find_username view:
#extends('master')
#section('content')
<div class="row">
<table class="table">
<thead>
<tr>
<th>ID Role</th>
<th>Role name</th>
<th>Role level</th>
<th>Role note</th>
<th>User name</th>
</tr>
</thead>
<tbody>
#foreach ($roles as $item)
<tr>
<td>{{$item['id']}}</td>
<td>{{$item['role_name']}}</td>
<td>{{$item['role_level']}}</td>
<td>{{$item['role_note']}}</td>
<td>{{$item->users}}</td>
</tr>
#endforeach
</tbody>
</table>
</div>
#endsection
You have many roles. Each of these roles have many users. Your table will be fine as it is to show the name of the role, roll level, and role note, because these are on the looped $item variable individually.
The problem is that while the $item holds those singular fields, the $item->users is another collection of user objects. Which means you have added another dimension onto your table. You might have 1 or 100 users to fit inside that <tr>.
To demonstrate, try this code, specifically adding in all the users names (adding the parameter to each user object in a new loop):
#foreach ($roles as $item)
<tr>
<td>{{$item['id']}}</td>
<td>{{$item['role_name']}}</td>
<td>{{$item['role_level']}}</td>
<td>{{$item['role_note']}}</td>
#foreach($item->users as $user)
<td>
{{$user->name}}
{{$loop->last?"":" | "}} //<-- just to separate names for this test
</td>
#endforeach
</tr>
#endforeach
If you have your models and relations set up correctly, this will show you your users for each role. However, as you can see, this may not be the best way to display this data. You might have dozens of users per role. You may wish to consider making a totally separate table for each role's users. Maybe click on something for the role on this table and bring up a new list or table of those users who have the role.

I'm getting trouble in getting the data from foreign key .
already make relation between 2 tables, but still error gave me this "Trying to get property of non-object"
this is my models
public function tourism()
{
return $this->belongsTo('App\Models\Tourism','tourism_id');
}
this is my controller
$ratings = Ratings::orderBy('rating','desc')->get();
$ratings = $ratings->take(6);
and this is my blade
<tbody>
#if($ratings)
#foreach($ratings as $data)
<tr>
<td class="center">{{$data->id}}</td>
<td class="center">{{$data->tourism_id->nama}}</td>
<td class="center">{{$data->rating}}</td>
</tr>
#endforeach
#endif
</tbody>
thanks
Try
<td class="center">{{$data->tourism->nama}}</td>
EDIT
This situation occurs when you trying get nama property.
But tourism_id it's just an integer, am I right?
First of all,for accessing related model you should use you relationship method(tourism) instead of FK field(tourism_id).
Then you should check are there any related model in tourims() or not. For this purpose i recommend you use ternary operator, so your line should be something like:
<td class="center">{{$data->tourism->first() ? $data->tourism->first()->nama : 'No tourism'}}</td>
Assuming you already have this controller and the model relationship as above:
function ratingsView() {
$ratings = Ratings::orderBy('rating','desc')->get();
$ratings = $ratings->take(6);
return View('rating')->with('ratings',$ratings);
}
In your views,
<tbody>
#if($ratings)
#foreach($ratings as $data)
<tr>
<td class="center">{{$data->id}}</td>
<td class="center">{{$data->tourism()->first()->nama}}</td>
<td class="center">{{$data->rating}}</td>
</tr>
#endforeach
#endif
</tbody>
Make sure your rating table have id, rating as well as tourism_id attributes and your tourism table have name attribute as well as of course there is data in both tables.
You definitely need to check the the availability of the data and handle it accordingly. But that is different issue
in your controller use it like this:
$ratings = Ratings::orderBy('rating','desc')->take(6)->get();
