i can't figure out why my eloquent relationship is not working.
I have the grid and details tables related (es. grid.id = details.order_id). This works for first 2 tables but not for other 2 that are almost a copy of the first.
Working relationship code :
OrderGrid model:
use HasFactory;
protected $table = 'orders_grid';
protected $fillable = [
'user_id',
// more data
];
public function order_detail()
{
return $this->hasMany('App\Models\OrderDetail');
}
OrderDetail model:
use HasFactory;
protected $table = 'orders_detail';
protected $fillable = [
'order_id',
// more data
];
public function order_grid()
{
return $this->belongsTo('App\Models\OrderGrid', 'order_id', 'id');
}
In controller
$data_details = OrderDetail::where('order_id', $id)->get();
in view
$data_details->first()->order_grid->id
// so i can get the ID from the related table
Now i have two more very similar models which relations are not working:
OrderGrid model 2
use HasFactory;
protected $table = 'orders_grid_jde';
protected $fillable = [
'total_order',
// more data
];
public function detail_jde()
{
return $this->hasMany('App\Models\OrderDetailJde');
}
OrderDetail model 2 :
use HasFactory;
protected $table = 'orders_detail_jde';
protected $fillable = [
'order_jde_id',
];
public function grid_jde()
{
return $this->belongsTo('App\Models\OrderGridJde', 'order_jde_id', 'id');
}
In controller:
$data_details = OrderDetailJde::where('order_jde_id', $id)->get();
In view:
$data_details->first()->order_jde_id->id
This is not working, if i dump($data_details->first()) relations is empty array, not as in the screen shown before
Another weird behaviour on working relation: if i dump $data_details->first() in the controller i don't see the relation, but if i do it in view it shows as in the screen.
Sorry for the long post, tried to be understandble as possible
In your Controller call the relation like this:
$data_details = OrderDetailJde::where('order_jde_id', $id)->with("grid_jde")->get();
In view:
$data_details->first()
It will give all the detils.
It should work now.
In the view where you have the error, you are accessing the directly to the field named order_jde_id instead of the relationship grid_jde.
Tips:
You should eager load the relationships if you are planning to use these in the view.
$books = Book::with('author')->get();

I have three table in DB, and I have used belongsTo for merging them. My Admins model looks like this :
class Admin extends Authenticatable
{
use HasFactory;
protected $guarded = ['status', 'shop_name', 'vendor_id', 'id'];
protected $guard = 'admin';
public function getVendorDetails(){
return $this->belongsTo(Vendor::class, 'vendor_id','vendor_id');
}
public function getVendorBusinessDetails(){
return $this->belongsTo(VendorBusinessDetails::class, 'vendor_id','vendor_id');
}
}
I need to prevent shop-name field to be saved through form. this field is in the table name : vendor_business_detals (getVendorBusinessDetails).But in this case $guarded only works for Admins table and ignores another relationship tables and fields of them such as shop_name. In short I am struggling to find the way to add $guarded data for VendorBusinessDetails. My controller looks like below:
$business_data = $request->only(['shop_name', 'shop_address', 'shop_phone']);
//dd($business_data);
$myModel = Admin::find($id);
//business table update
$myModel->getVendorBusinessDetails()->update($business_data);
VendorBusinessDetails model:
class VendorBusinessDetails extends Model
{
use HasFactory;
protected $guarded = ['shop_name'];
protected $table = 'vendors_business_details';
}
I don't know why $guraded=['shop_name'] is ignored. Any help would be highly appreciated.
$myModel->getVendorBusinessDetails()->update($business_data);
If you use "getVendorBusinessDetails" as a method, the model isn't initialize. Only the SQL update command runs.
$myModel->getVendorBusinessDetails->update($business_data);
Using "getVendorBusinessDetails" as a field initializes the model. So, it works as you expected.
I have below code to get data from database,
$profile = Profiles::find(1);
$currency = Profiles::find($profile->currency_id)->currency;
Then created a relationship in the model as below,
class Profiles extends Model
{
use HasFactory;
protected $table = 'Profiles';
protected $primaryKey = 'profile_id';
public function Currency()
{
return $this->belongsTo(Currencies::class, 'currency_id');
}
}
class Currencies extends Model
{
use HasFactory;
protected $table = 'Currencies';
protected $primaryKey = 'currency_id';
public function profile()
{
return $this->hasOne(Profiles::class, 'currency_id');
}
}
Problem is that there is only 1 profile and 100 currency, currency_id is a foreign key in Profiles table,
I could not get data and get this error, Trying to get property 'currency' of non-object"
If i use $currency = Profiles::find(1)->currency; then it retrieve first row of Curriencies table which is not required data.
How can I get currency row for that specific profile?
The problem is that the find() method will look for the primaryKey and in your second call the currency_id is not the pk.
Two solution for you:
replace the find by a where clause like so: $currency = Profiles::where('currency_id',$profile->currency_id)->value('currency')
Or a more Laravel way to do it, through the relationship $currency = $profile->currency;
if i have this models relationship
Claims : this table hasMany(Refunds)
Refunds: with data of various request. this table belongsTo(Claims) AND belongsToMany(Services)
Services: with list of services. this table belongsToMany(Refunds)
Refunds-Services: bridge table for refunds and services
Claims model
class Claims extends Model
{
public $primaryKey = 'id';
protected $fillable = [
'dossier',
'date_cla',
];
public function refunds()
{
return $this->hasMany(Refunds::class);
}
}
Refunds model
class Refunds extends Model
{
public $primaryKey = 'id';
protected $fillable = [
'date_ref',
'status_ref',
];
public function services()
{
return $this->belongsToMany(Services::class)->withPivot(['services_id','services_amount','services_status']);
}
public function claims()
{
return $this->belongsTo(Claims::class,'claims_id');
}
}
Services model
class Services extends Model
{
public $primaryKey = 'id';
protected $fillable = [
'code',
'name',
];
public function refunds()
{
return $this->belongsToMany(Refunds::class);
}
}
and in my controller this method
if ($request->ajax()) {
$dossier = request('dossier');
$claim = Claims::with('refunds')
->where('dossier', '=', $dossier)->first();
$
$view = view('pages.modify', compact('claim'));
$sections = $view->renderSections()['table'];
return $sections;
}
how can insert in the Controller the relationship between Refunds and Service to use the pivot (service_amount is in the Refunds-Services table)
<li>- {{ $item->pivot->services_amount }}</li>
Because now in the view cannot see this relationship
Thx
You can use Nested Eager Loading
$claim = Claims::with('refunds.services')
->where('dossier', '=', $dossier)->first();
As per the documentation:
To eager load nested relationships, you may use "dot" syntax. For example, let's eager load all of the book's authors and all of the author's personal contacts in one Eloquent statement:
$books = App\Book::with('author.contacts')->get();
Rather than doing something like this (which I do dozens of times across the site):
$posts = Post::with('user')
->with('image')
->get();
Is it possible to automatically call with('image') whenever with('user') is called? So in the end, I could do just:
$posts = Post::with('user')
->get();
And still eager load image?
Add the following in your model:
protected $with = array('image');
and that should do the trick.
The $with attribute lists relations that should be eagerly loaded with every query.
Here another solution that works like a charm !
class Post extends Model {
protected $table = 'posts';
protected $fillable = [ ... ];
protected $hidden = array('created_at','updated_at');
public function user()
{
return $this->belongsTo('App\Models\User');
}
public function userImage()
{
return $this->belongsTo('App\Models\User')->with('image');
}
}
$posts = Post::with('userImage')->get();
Using this you can still use your user posts $posts = Post::with('user')->get(); whenever you don't want to make an additional call to retrieve images ..
I'm trying out this model-thing, but I can't really get my grasp of it.
For the moment I have two tables (companies and sellers) "companies" as a column named "cResponsibleID" which I want to map to "sID" in "sellers".
models/Companies.php
class Companies extends Eloquent {
protected $table = 'companies';
protected $primaryKey = 'cID';
public function sellers() {
return $this->belongsTo('Sellers','sID');
}
}
models/Sellers.php
class Sellers extends Eloquent {
protected $table = 'sellers';
protected $primaryKey = 'sID';
public function companies() {
return $this->hasMany('Companies','cResponsibleID');
}
}
I then want to do something like Companies::with('sellers.sName')->get() to "translate" cResponsibleID to sName.
Maybe I'm all out wrong.
Thankful for all help.
Can you try printing the result of:
<?php
$company = Companies::with('sellers')->get();
echo '<pre>';
print_r($company->sellers);
And see how they're build up, I blieve the sellers.ANYTHING construction is only meant for multiple nested relations.
for example of a Seller has an Address as a relation, it would be Companies::with('sellers.address')
