How to get data to table that has many relationships in Eloquent - php

I am trying to work on an eloquent model Post where it has two hasOne relationships: offer_post and request_post.
Post.php
class Post extends Model
{
use HasFactory;
protected $table = 'tbl_post';
protected $fillable = ['email', 'postIdentity', 'postStatus'];
public $timestamps = false;
public $primaryKey = 'indexPost';
public static function boot()
{
parent::boot();
self::creating(function ($model) {
$model->postNumber = (string) Uuid::generate(4);
});
}
public function pasabuy_user() {
$this->belongsTo(PasabuyUser::class, 'email', 'email');
}
public function offer_post() {
return $this->hasOne(OfferPost::class, 'postNumber', 'postNumber');
}
public function request_post() {
return $this->hasOne(RequestPost::class, 'postNumber', 'postNumber');
}
}
OfferPost.php
class OfferPost extends Model
{
use HasFactory;
protected $table = 'tbl_shoppingOfferPost';
protected $fillable = ['postNumber', 'postStatus', 'deliveryArea', 'shoppingPlace', 'deliverySchedule', 'transportMode', 'capacity', 'paymentMethod', 'caption'];
public $timestamps = false;
public $primaryKey = 'indexShoppingOfferPost';
public function post() {
return $this->belongsTo(Post::class, 'postNumber', 'postNumber');
}
}
RequestPost.php
class RequestPost extends Model
{
use HasFactory;
protected $table = 'tbl_orderRequestPost';
protected $fillable = [
'postNumber',
'postStatus',
'deliveryAddress',
'shoppingPlace',
'deliverySchedule',
'paymentMethod',
'shoppingList',
'caption'
];
public $timestamps = false;
public $primaryKey = 'indexOrderRequestPost';
/**
* [post description]
* #author Al Vincent Musa
* #return [type] [description]
*/
public function post() {
return $this->belongsTo(Post::class, 'postNUmber', 'postNumber');
}
}
This is how my tables looks like.
Now I want to get all post(both offer post and request post)
Get offer post like
SELECT from tbl_post INNER JOIN tbl_shoppingOfferPost ON tbl_post.postNumber = tbl_shoppingOfferPost.postNumber
and likewise for the request post.
I came as far as
$post = Post::has('offer_post')->get();
but this only returns data from tbl_post. But want both from tbl_post and tbl_shoppingOfferPost.
I am having a hard time understanding the docs. I don't know where to start. Any help is much appreciated. I just need a pointer where to look at. Thanks

You can do like this
$post::with(['offer_post','request_post'])->get();

how to access a function from model file

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'));
}

Relations in Laravel eloquent

I am beginner in Laravel. I use in my project Laravel 5.8.
I have this code:
Dish.php
class Dish extends Model
{
protected $quarded = ['id'];
protected $fillable = ['company_id', 'name', 'description', 'enable'];
public $timestamps = false;
public function components()
{
return $this->hasManyThrough('App\DishValues', 'App\Dish', 'id', 'dishes_id');
}
}
DishValues
class DishValues extends Model
{
protected $quarded = ['id'];
protected $fillable = ['dishes_id', 'food_ingredient_id', 'quantity'];
public $timestamps = false;
public function ingredient()
{
return $this->belongsTo('App\FoodIngredient', 'food_ingredient_id');
}
}
FoodIngredient.php
class FoodIngredient extends Model
{
use scopeActiveTrait;
public function scopeVisibleDemo($query)
{
return $query->where('available_in_demo', 1);
}
protected $quarded = ['id'];
protected $fillable = ['company_id', 'name', 'garbage', 'energy_value', 'protein', 'fat', 'available_carbohydrates', 'roughage', 'description', 'url_address', 'allergen', 'available_in_demo', 'enable'];
public $timestamps = false;
}
I get my data:
Dish::with('components')->paginate(25);
How can I get in this code values from FoodIngredient?
This is not working:
Dish::with('components, ingredient')->paginate(25);
or
Dish::with('components')->with('ingredient')->paginate(25);
Given you have multiple relationships, you use :with() with an array of values, not a comma separated string.
This example comes from the docs on "Eager Loading Multiple Relationships" and I've re-named the models based on your example
App\Dish::with(['components', 'ingredient'])->get();
There is also a good blog post that explores the eager/lazy loading of related models in this way.

Laravel MongoDB hasMany relationship is not working

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');
}

Laravel 5 Call to undefined method Illuminate\Database\Eloquent\Collection::tags();

I have two Models that use a many to many relationship.
class Tag extends Model
{
protected $table= 'tags';
protected $primaryKey = 'id';
protected $fillable = [
'name'
];
public function members()
{
return $this->belongsToMany('App\Data','data_tag','tag_id','data_id')
->withTimestamps();
}
}
and a Data Model..
class Data extends Model
{
protected $table= 'dbaccess';
protected $primaryKey = 'id';
protected $fillable = [
'username','password','email','added_at','user_id'
];
/**
* #return \Illuminate\Database\Eloquent\Relations\BelongsToMany
*/
public function tags()
{
return $this->belongsToMany('App\Tag','data_tag','data_id','tag_id')
->withTimestamps();
}
}
where the data_tag is linking a table.
when I call the function
$mani = App\Data::find(2);
and then
$mani->tags()->attach(3);
I get the following error.
[Symfony\Component\Debug\Exception\FatalErrorException]
Call to undefined method Illuminate\Database\Eloquent\Collection::tags()
Can anyone help me with this ?
dd($mani) reply this
It seems you are getting a collection instead of a model
Try to get the first element of the collection with:
$mani = App\Data::find(2)->first();

Laravel 4 model relationship through another model

I'm trying to bind multiple models to a form. Currently, I have 4 models:
<?php
class DemDataSet extends Eloquent {
public $timestamps = false;
protected $connection = 'epcr_dem_data';
protected $table = 'DEMDataSet';
protected $primaryKey = 'pk_DEMDataSet';
public function DemographicReport(){
return $this->hasOne('DemographicReport','fk_DemDataSet','pk_DemDataSet');
}
}
class DemographicReport extends Eloquent {
public $timestamps = false;
protected $connection = 'epcr_dem_data';
protected $table = 'DemographicReport';
protected $primaryKey = 'pk_DemographicReport';
public function DemDataSet(){
return $this->belongsTo('DemDataSet','fk_DemDataSet','pk_DemDataSet');
}
public function dAgency(){
return $this->hasOne('dAgency','fk_DemographicReport','pk_DemographicReport');
}
}
class dAgency extends Eloquent {
public $timestamps = false;
protected $connection = 'epcr_dem_data';
protected $table = 'dAgency';
protected $primaryKey = 'pk_dAgency';
public function DemographicReport(){
return $this->belongsTo('DemographicReport','fk_DemographicReport','pk_DemographicReport');
}
public function dAgency_10(){
return $this->hasMany('dAgency_10','fk_dAgency','pk_dAgency');
}
}
class dAgency_10 extends Eloquent {
public $timestamps = false;
protected $connection = 'epcr_dem_data';
protected $table = 'dAgency_10';
protected $primaryKey = 'pk_dAgency_10';
public function dAgency(){
return $this->belongsTo('dAgency','fk_dAgency','pk_dAgency');
}
}
?>
And I'm passing it to my view through my controller like so:
public function index()
{
//THIS is the line I need help with (I think):
$agency = dAgency::with('dAgency_10','DemographicReport')->find(1);
//for troubleshooting:
echo "<pre>",print_r(dAgency::with('dAgency_10','DemographicReport')->find(1)->toArray()),"</pre>";
return View::make('test')
->with('agency', $agency);
}
I'm able to bind everything except for data from the DemDataSet model, which I can't even figure out how to establish the relationship between it and my dAgency model. So basically, I just want the fields in the DemDataSet model to be available to my view, then obviously I want to be able to perform all the CRUD operations eventually.
Looking at your models, you should just be able to access it via the DemographicReport.
i.e.,
$dataset = $agency->DemographicReport->DemDataSet;
