Area table Migration and data
Bid table Migration and data
When I am trying to access
Bid::with('area')->find(BID_ID);
It is returning Null
Query is firing wrong:
"select * from `location_area` where `location_area`.`area_id` in (0)"
But if I am doing like:
$bid = Bid::find(BID_ID);
dd($bid->area);
It returns Area table values. What is going wrong? Please Help me. I
am having this problem for a long time. Thank You in advance :)
you must be declared a method in your MID model
public function area()
{
return $this->belongsTo(Area::class, 'bid');
}
something like this
after this, you access area in with()
Bid::with('area')->find(BID_ID);
Change this function in your Bid model :
public function area() {
return $this->belongsTo(Area::class, 'area_id');
}

I have a problem, I am trying to retrieve orders with products from my database. The idea is that you have an order with products in it and a product can have options with different options. For example a big mac menu has different options, such as size with three different options. This is what I have now:
OrderModel:
class Order extends Model
{
use HasFactory;
protected $table = 'orders';
public function user()
{
return $this->belongsTo(User::class);
}
public function table()
{
return $this->belongsTo(Table::class);
}
public function branch()
{
return $this->belongsTo(Branch::class);
}
public function products()
{
return $this->belongsToMany(Product::class)->withPivot('quantity');
}
}
OrderProduct:
class OrderProduct extends Pivot
{
use HasFactory;
public $incrementing = true;
protected $table = 'order_product';
public function options()
{
return $this->hasMany(OrderProductOptions::class);
}
public function products()
{
return $this->hasMany(Product::class);
}
}
OrderProductOptions:
class OrderProductOptions extends Model
{
use HasFactory;
public $incrementing = true;
protected $table = 'order_product_options';
public function options()
{
return $this->belongsTo(OrderProductsOptionsOptions::class);
}
}
OrderProductsOptionsOptions:
class OrderProductsOptionsOptions extends Model
{
use HasFactory;
protected $table = 'order_products_options_options';
public function Option()
{
return $this->belongsTo(OrderProductOptions::class);
}
}
When I want to pick up an order with products and selected options like this:
$newOrder = Order::with('products.options')->findOrFail($order->id);
I get all the options that the product has, how do I get only the selected ones that belong to the order?
see laravel document , you must define foringPivotKey and relatedPivot key like this:
return $this->belongsToMany(Role::class, 'role_user', 'user_id', 'role_id');
im using laravel 7.24 and php 7.4 on my project
What i want to is fundementally creating relations between 3 table and using them in 'one' query.
to be specific i need to access 'ordered products' from my order detail page.
public function orderdetail($id)
{ //certainorder model access to 'ShoppingCard'model from below
$orderDetails = CertainOrder::with('ShoppingCard.shoppingCardProducts.product')
->where('ShoppingCard.id' , $id)->firstorFail();
return view('orderdetails', compact ('orderDetails'));
}
CertainOrder model access to 'ShoppingCard' model from top and in the ShoppingCard model it contains shoppingCardProducts function which you will see in below and with shoppingCardProducts function my 'products' table had a relation. the problem is something in relations is wrong and i can't get data from shoppingcardproduct
class ShoppingCard extends Model
{
protected $table = "shopping_card";
protected $fillable = ['id', 'user_id', 'created_at','updated_at'];
public function shoppingCardProducts()
{
return $this->hasMany('App\ShoppingCardProduct');
}
class CertainOrder extends Model
{
protected $table = "certain_orders";
protected $guarded = [];
public function shoppingCard()
{
return $this->belongsTo(ShoppingCard::class, 'sepet_id');
//sepet_id is a foreign key.
}
class ShoppingCardProduct extends Model
{
use SoftDeletes;
protected $table = "shopping_card_product";
protected $fillable = ['id', 'sepet_id', 'urun_id','quantity','price','status','created_at','updated_at','deleted_at'];
public function product()
{
return $this->belongsTo('App\Product');
}
I think you missed it somewhere in the code
class ShoppingCard extends Model
{
protected $table = "shopping_card";
protected $fillable = ['id', 'user_id', 'created_at','updated_at'];
public function shoppingCardProducts()
{
return $this->hasMany('App\ShoppingCardProduct');
}
public function CertainOrder(){
return $this->hasMany('path\to\model');
}
public function ShoppingCardProduct(){
return $this->hasMany('path\to\model');
}
}
class CertainOrder extends Model
{
protected $table = "certain_orders";
protected $guarded = [];
public function shoppingCard()
{
return $this->belongsTo('App\path\to\model', 'sepet_id');
//sepet_id is a foreign key.
}
}
class ShoppingCardProduct extends Model
{
use SoftDeletes;
protected $table = "shopping_card_product";
protected $fillable = ['id', 'sepet_id', 'urun_id','quantity','price','status','created_at','updated_at','deleted_at'];
public function ShoppingCard()
{
return $this->belongsTo('App\ShoppingCard');
}
}
and make the call this way
public function orderdetail($id)
{ //certainorder model access to 'ShoppingCard'model from below
$orderDetails = ShoppingCard::with('CertainOrder, ShoppingCardProduct')
->where('id' , $id)->firstorFail();
return view('orderdetails', compact ('orderDetails'));
}
I am trying to create a relationship between Player and Roleplay and its returning null. I know for a fact it should be working because the following code works perfectly:
Roleplay::find(Auth::user()->id);
And returns the correct data, a full array of the correct data.
When trying to access it this way:
Auth::user()->roleplay->user_id;
It doesn't work, can someone help me find out why?
How do you know its empty?
Because {{var_dump(Auth::user()->roleplay)}} in blade view returns EMPTY
When using it the view I also get a undefined error.
Primary key of roleplay table (srp_user_statistics) is user_id, and the primary key of player table (users) is id
here is the code:
Player:
<?php
namespace App\Database\Frontend\User;
use Hash;
use Eloquent;
use \Illuminate\Auth\Authenticatable;
use \Illuminate\Contracts\Auth\Authenticatable as Authentication;
class Player extends Eloquent implements Authentication
{
use Authenticatable;
protected $primaryKey = 'id';
protected $table = 'users';
public $timestamps = false;
protected $fillable = [];
public function setPasswordAttribute($value)
{
$this->attributes['password'] = Hash::make($value);
}
public function setUsernameAttribute($value)
{
return $this->attributes['username'] = $value;
}
public function roleplay()
{
return $this->hasOne('App\Database\Frontend\User\Roleplay', 'user_id');
}
}
Roleplay:
use Eloquent;
class Roleplay extends Eloquent
{
protected $primaryKey = 'user_id';
protected $table = 'srp_user_statistics';
public $timestamps = true;
protected $fillable = [];
public function user()
{
return $this->belongsTo('App\Database\Frontend\User\Player', 'user_id', 'id');
}
public function government_role()
{
return $this->belongsTo('App\Database\Frontend\Roleplay\GovernmentRole', 'government_id');
}
}
I thinks you should add 'id' to hasOne() in the User model
public function roleplay()
{
return $this->hasOne('App\Database\Frontend\User\Roleplay', 'user_id', 'id');
}
And remove 'id' from belonsTo() in Roleplay model.
Side notes
This working
Roleplay::find(Auth::user()->id);
Is not a guarantee your relationships are set properly. All it does is
Roleplay::find(1); //$user->id returns an integer.
I'm try to create a relationship between albums and photos (an Album has many photos). Below is my controller and what my models look like. Interesting enough, the reverse relationship photo->album (belongsTo) works fine! but the album->photos returns an empty collection.
## The hasMany relationship does NOT work... I get an empty collection
<?php
class AlbumController extends BaseController
{
public function show(Request $request, $album_id)
{
$album = Album::find($album_id);
dd($album->photos);
}
}
## Results:
# Collection {#418
# items: []
# }
## The belgonsTo relationship works
<?php
class PhotoController extends BaseController
{
public function show(Request $request, $photo_id)
{
$photo = Photo::find($photo_id);
dd($photo->album);
}
}
<?php
namespace App;
use DB;
use Jenssegers\Mongodb\Eloquent\SoftDeletes;
use Moloquent;
class Album extends Moloquent
{
use RecordActivity, SoftDeletes;
protected $connection = 'mongodb';
protected $table = 'albums';
protected $collection = 'albums';
protected $primaryKey = "_id";
protected $dates = ['deleted_at'];
protected $fillable = ['user_id','name','is_private'];
public function photos()
{
// Neither seems to work
//return $this->embedsMany('Photo');
return $this->hasMany('App\Photo');
}
}
<?php
namespace App;
use DB;
use Jenssegers\Mongodb\Eloquent\SoftDeletes;
use Moloquent;
class Photo extends Moloquent
{
use RecordActivity, SoftDeletes;
protected $connection = 'mongodb';
protected $table = 'photos';
protected $collection = 'photos';
protected $primaryKey = "_id";
protected $dates = ['deleted_at'];
protected $fillable = ['album_id', 'user_id', 'name', 'folder', 'is_private', 'caption'];
protected $hidden = [];
// user and album belongsTo works
public function user()
{
return $this->belongsTo('App\User');
}
public function album()
{
return $this->belongsTo('App\Album');
}
}
The issue had to do with the fact that my IDs were ObjectID and it seems to be an issue with Jessengers Laravel MongoDB Drivers... we have actually decided to move back to MariaDB to fully utilize Eloquent/Relationships
I did the same thing as yours and i found that nothing wrong with Mongodb. Because Mongodb defined the "_id" as primary key and that's the reason it couldn't get the correct relationship: belongsTo and hasMany. So i did a small change by declared the $primaryKey = "id" on the top of parent Model and it worked fine
this worked for me.
/**
* #return HasMany
*/
public function tasks(): HasMany
{
return $this->hasMany(ProjectTask::class, 'project_id', 'idAsString');
}
I have four tables and I am giving my table structure here
user_work['id', 'user_id', 'work_id']
work_sectors['id', 'name', 'status']
works['id', 'work_sector_id', 'work_type_id', 'work_duration_id', 'name']
users['id', ...]
And My Models are
class User extends Eloquent implements UserInterface, RemindableInterface
{
use UserTrait, RemindableTrait;
protected $table = 'users';
public function work()
{
return $this->belongsToMany('Work', 'user_work');
}
}
class Work extends \Eloquent {
protected $fillable = [];
protected $table_name = 'works';
public $timestamps = false;
public function user()
{
return $this->belongsToMany('User', 'user_work');
}
public function sector()
{
return $this->belongsTo('WorkSector', 'work_sector_id');
}
}
In my controller I have written this code
$user = User::with('language')->with('work')->find($userId);
Here I need name of work_sector table but probably I have written wrong code to get the sector name.
So please help me to write a proper function in this eloquent method in laravel 4.2.
