I am a new learner of the laravel framework working on 3 models
customer,
accidents,
License
where the relations are as follows:
public function License()
{
return $this->hasOne(license::class,'driver_id');
}
public function cars()
{
return $this->hasMany(car::class);
}
In the controller I do like this:
public function AdminCustomers()
{
$customers = Customer::with('cars')->with('License')->get();
return view('admin.AdminCustomers',compact('customers'));
}
now I want to display all 3 models' data on view.blade page
<tbody>
#foreach($customers as $customer)
<tr>
<td>{{$customer->id}}</td>
<td>{{$customer->name}}</td>
<td>{{$customer->adderss}}</td>
<td>{{$customer->mobileNo}}</td>
<th>{{$customer->License->id}}</th>
<th>{{$customer->License->Exp}}</th>
<td>{{$customer->cars->id}}</td>
<td>{{$customer->cars->color}}</td>
<td>{{$customer->cars->model_no}}</td>
<td>{{$customer->cars->company}}</td>
</tr>
#endforeach
</tbody>
But it doesn't work and I didn't know where is the problem
the error Exception
Property [id] does not exist on this collection instance.
$customer->cars will return a collection as the relationship is hasMany so you need to loop over the collection in the view
#foreach($customers as $customer)
<tr>
<td>{{$customer->id}}</td>
<td>{{$customer->name}}</td>
<td>{{$customer->adderss}}</td>
<td>{{$customer->mobileNo}}</td>
<th>{{$customer->License->id}}</th>
<th>{{$customer->License->Exp}}</th>
#foreach($customer->cars as $car)
<td>{{$car->id}}</td>
<td>{{$car->color}}</td>
<td>{{$car->model_no}}</td>
<td>{{$car->company}}</td>
#endforeach
</tr>
#endforeach
check the name in the corrisponding table on db, and if its different from "id" specify it into the model, as
protected $primaryKey = 'xxx';

I have a Customer model and Customer hasMany Xray_machines. I am trying to select the oldest cert_date from the xray_machines table to populate a table in the view that lists the customer_name and the oldest cert_date. I found oldestOfMany() and it seems to be a good option but it is displaying the first cert_date rather than the oldest.
Customer Model
public function xray_machine()
{
return $this->hasMany(Xray_machine::class);
}
public function oldestCert(){
return $this->hasOne(Xray_machine::class)->oldestOfMany('cert_date','min');
}
Controller
public function xray_unscheduled(){
$due = Carbon::now()->addMonth(3)->endOfMonth()->toDateTimeString();
$customers = Customer::whereHas('Xray_machine', function ($query) use($due) {
$query->where('cert_date','<=', $due);
})
->whereNull('xray_scheduled')->orWhere('xray_scheduled','<>','')
->oldestCert()
->orderBy(
Xray_machine::select('cert_date')
->whereColumn('xray_machines.customer_id','customers.id')
->take(1),'asc'
)
->get()->all();
return view('work_orders/xray_unscheduled', compact('customers'));
}
View
#foreach ($customers as $customer)
<tr>
<td>
{{ $customer->customer_name}}
</td>
<td>
{{ \Carbon\Carbon::parse($customer->oldestCert()->cert_date)->format('Y-m-d')}}
</td>
</tr>
#endforeach
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>{{$claim->pivot->IBAN}}</td>
</tr>
#endforeach
when I am trying to add #foreach 3 times it's repeating my data. how do I solve this?
and am using Livewire.
Small Summery :
I will try to make a Student Management system using Laravel and livewire. basically, I am trying to make a payment system based on Monthly, Termly, and Year so it's also separate to more. Example We have Different price Value of Monthly Payment Scheme Students.
this is my code
public function mount($students){
$students = Student::With('FeeScheem','FeeScheemInd','FeeGroup','FeeMaster','FeeCollector')
->where('students.stu_id',$students )
->get();
$this->students = $students;
// DD($students);
}
Eloquent Relationship
public function FeeScheem()
{
return $this->hasOne(FeeScheem::class, 'fs_id', 'stu_fee_scheems');
}
public function FeeScheemInd()
{
return $this->hasOne(FeeScheemInd::class, 'ind_id', 'stu_ind_fee_scheems');
}
public function FeeGroup()
{
return $this->hasMany(FeeGroup::class, 'fee_group_fee_scheem_id', 'stu_fee_scheems');
}
public function FeeMaster()
{
return $this->hasOne(FeeMaster::class, 'fee_master_ind_fs_id', 'stu_ind_fee_scheems');
}
public function FeeCollector()
{
return $this->hasMany(SchoolFeeCollector::class, 'fc_stu_id', 'stu_id');
}
This is My Blade File
<tbody>
#foreach($students as $Student)
#foreach($Student->FeeGroup as $FeeG)
#foreach($Student->FeeCollector as $FeeC)
<tr>
<td></td>
<td>{{$FeeG->fee_group_name}}</td>
<td>{{$FeeG->fee_master_due_date}}</td>
<td></td>
<td>{{$Student->FeeMaster->fee_master_amount}}</td>
</tr>
#endforeach
#endforeach
#endforeach
</tbody>
Here the table view in Blade file
I have 2 tables which are user and customer, The first table has the following fields: (id, name, email, password)
Then, the table customer has the following fields: (id, name, firstname).
In my Controller Customer, via my function index(), I have to retrieve id_user from my table user.
Question 1: Is my relationship correct between my 2 tables?
Model Customer
protected $fillable = ['name', 'firstname', 'user_id'];
public function user()
{
return $this->belongsTo('App\User');
}
Model User
public function customers()
{
return $this->hasOne('App\Customer');
}
Question 2: How do I retrieve ID of the user who is connected ?
I have for now this only...
public function index()
{
$customers = Customer::orderby('id', 'desc')->paginate(5);
return view('customers.index', compact('customers'));
}
Question 3: I want to understand the two answers, but I would also like to understand how I can adapt my file index.blade.php via my loop, please.
#foreach($customers as $customer)
<tr>
<td> {{$customer->name}}</td>
<td> {{$customer->firstname}}</td>
Thank you for your explanations.
Your models are good. If you want to return user relation for every customer you should try like this:
public function index()
{
$customers = Customer::with('user')->orderby('id', 'desc')->paginate(5);
return view('customers.index', compact('customers'));
}
And in your view you should have:
#foreach($customers as $customer)
<tr>
<td> {{$customer->name}}</td>
<td> {{$customer->firstname}}</td>
<td> {{$customer->user->id}}</td>
More about that here.
Question 1: Is my relationship correct between my 2 tables?
Yes, your relationship is correct.
Explanation:
For your customer table, you indicate that a customer profile belongs to one and only one user. This is an inverse one-to-one entity relationship.
For your user table, you indicate that a user has one and only one customer profile. This is a one-to-one entity relationship.
Question 2: How do I retrieve ID of the user who is connected?
Use Laravel's Eager Loading by calling the with() method to retrieve the customer data with the associated user data like this:
public function index()
{
$customers = Customer::with('user')->orderby('id', 'desc')->paginate(5);
return view('customers.index', compact('customers'));
}
Explanation:
The returned result can be visualized like this:
{Customer}
|
•id
•name
•firstname
•{user}
|
• id
• name
• email
Finally you can get the results including the user ID in your view like this:
#foreach($customers as $customer)
<tr>
<td>{{ $customer->user->id }}</td>
<td>{{ $customer->firstname }}</td>
<td>{{ $customer->name }</td>
</tr>
#endforeach
For more details on Laravel Entity Relationships see the relevant Laravel documentation.
i try it on this way but not dispalyed the relation
model Admission
public function dossierscocial(){
return $this->hasOne('\App\Dossierscocial');
}
model Dossiersocial
public function admission(){
return $this->belongsTo('\App\Admission');
}
in my view
#if(isset($admission->dossiersocials))
#foreach($admission->dossiersocials as $dossiersocial)
<tr>
<td>{{$dossiersocial->id}}</td>
<td>{{$dossiersocial->user_id}}</td>
<td>{{$dossiersocial->patient_id}}</td>
<td>{{$dossiersocial->admission_id}}</td>
<td>{{$dossiersocial->nationalite}}</td>
</tr>
#endforeach
#endif
because hasOne return single object not collection so you can not use foreach.
there is just one object you can use it like this:
#if(isset($admission->dossiersocials))
<tr>
<td>{{$admission->dossiersocials->id}}</td>
<td>{{$admission->dossiersocials->user_id}}</td>
<td>{{$admission->dossiersocials->patient_id}}</td>
<td>{{$admission->dossiersocials->admission_id}}</td>
<td>{{$admission->dossiersocials->nationalite}}</td>
</tr>
#endif
or maybe you can use hasMany instead of hasOne
