Php Laravel get relation inside relation - php

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');

eloquent select all table with relationship many to many

I have 3 tables (workflow, user, workflow_user) and I would like to select the view column of the workflow_user table.
class Workflow extends Model
{
public function user()
{
return $this->belongsToMany(User::class,'workflow_user');
}
}
class User extends Model
{
public function works()
{
//return $this->belongsToMany(Role::class);
return $this->belongsToMany(Workflow1::class,'workflow_user');
}
}
workflow_user table
class WorkflowUser extends Model
{
protected $table = 'workflow_user';
protected $fillable = [
'workflow1_id','user_id','view'
];
protected $primaryKey = 'id';
public $timestamps = false;
}
To get the data from the workflow_user table I do this
$workflow = User::find($idconnect)->works()->orderBy('created_at','desc')->paginate(10);
When I make this request it does not give me the data of the workflow_user(workflow1_id,user_id,view) table.
If you have a model for the pivot table, you should have it extend the Pivot class and use it in the relationship's definition.
Also, you need to manually include the fields that are not the foreign ids in the query result.
class Workflow extends Model
{
public function user()
{
return $this->belongsToMany(User::class, 'workflow_user', 'workflow_id', 'user_id')
->using(WorkflowUser::class)
->withPivot(['id', 'view']);
}
}
class User extends Model
{
public function works()
{
return $this->belongsToMany(Workflow::class, 'workflow_user', 'user_id', 'workflow_id')
->using(WorkflowUser::class)
->withPivot(['id', 'view']);
}
}
workflow_user table
class WorkflowUser extends Pivot
{
protected $table = 'workflow_user';
protected $fillable = ['workflow_id', 'user_id', 'view'];
protected $primaryKey = 'id';
public $incrementing = true;
public $timestamps = false;
}
$workflow = User::findOrFail($idconnect)
->works()
->orderBy('created_at', 'desc')
->paginate(10);

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'));
}

Fetching Featured Posts with Review and Tag Laravel

I have 4 Eloquent.
class Featured extends \Eloquent {
protected $fillable = array('*');
public function courses() {
return $this->belongsTo('Course');
}
}
class Course extends \Eloquent {
protected $fillable = array('*');
public function featured() {
return $this->hasMany('Course');
}
public function review() {
return $this->hasMany('Course');
}
public function tag() {
return $this->hasMany('Course');
}
}
class Tag extends \Eloquent {
protected $fillable = array('*');
public function courses() {
return $this->belongsTo('Course');
}
}
class Review extends \Eloquent {
protected $fillable = array('*');
public function courses() {
return $this->belongsTo('Course');
}
}
I need to fetch all the featured courses, their review and tags.
Is it possible in 1 query? I have to show some featured posts on front page with their respective reviews and their tags.
This is Laravel 4.
You can use
Course::where('feature',1)->with('review')->with('tags')->get();
feature is a Column which tell course is feature or not.

How to create a hasManyTrough Eloquent relationship in this database schema?

I have the following tables
products
variants
attributes
options
option_variant
Look at this sqlfiddle for details http://sqlfiddle.com/#!2/eb1c73/24/0
Can I have something like this on my Product model to get all the attributes like I'm doing on the sqlfiddle query?
function attributes(){
return $this->hasManyThrough('Attributes','Variant');
}
THANKS!!
My Models:
<?php
class Product extends \Eloquent {
protected $table = 'products';
public function user()
{
return $this->belongsTo('User');
}
public function variants()
{
return $this->hasMany('Variant');
}
public function attributes(){
return $this->hasManyThrough('Attribute','OptionVariant');
}
}
<?php
class Variant extends \Eloquent {
protected $table = 'variants';
public function product()
{
return $this->belongsTo('Product');
}
public function options()
{
return $this->belongsToMany('Option');
}
}
<?php
class Attribute extends \Eloquent {
protected $table = 'attributes';
public function options()
{
return $this->hasMany('Option');
}
}
<?php
class Option extends \Eloquent {
protected $table = 'options';
public function attribute()
{
return $this->belongsTo('Attribute');
}
public function variants()
{
return $this->belongsToMany('Variant');
}
}
<?php
class OptionVariant extends \Eloquent {
protected $table = 'option_variant';
}
If you want take all atributtes all time that you select the products:
In Product model:
$with = ['attributes'];
In Controller:
$products = $this->product->findAll();
return View::make('products.index', compact('products'));
In View:
#foreach($products as $product)
{{ $product->attributes->column1 }}
#endforeach

dynamic query with laravel 4

hello friends need a hand with this query, failed to make it work, I'm new with laravel, I have 3 models:
DiscussCategory
class DiscussCategory extends Eloquent {
protected $table = 'discuss_category';
protected $guarded = array('id');
public function status() {
return $this->belongsTo('Status');
}
public function discuss() {
return $this->hasMany('Discuss');
}
}
Discuss
class Discuss extends Eloquent {
protected $table = 'discuss';
protected $guarded = array('id');
public function discussReplies() {
return $this->hasMany('DiscussReplies');
}
public function discussCategory() {
return $this->belongsTo('DiscussCategory');
}
public function users() {
return $this->belongsTo('Users');
}
}
Users
class Users extends Eloquent {
protected $table = 'users';
protected $guarded = array('id');
protected $hidden = array('password');
public function getAuthIdentifier() {
return $this->getKey();
}
public function getAuthPassword() {
return $this->password;
}
public function getReminderEmail() {
return $this->email;
}
public function discussReplies() {
return $this->hasOne('DiscussReplies');
}
public function discuss() {
return $this->hasMany('Discuss');
}
}
and this how I try to show the query in view
#foreach($data as $category)
{{$category->discuss->last()->users->nickname}}
#endforeach
if you run a foreach manages to get users, but I just want the name of the last user to post a discuss
Trying to get property of non-object
appreciate a hand, insurance is not much, but I have little experience
In your Discuss model change following method:
public function users() {
return $this->belongsTo('Users');
}
To this (use user not users)
public function user() {
// Assumed one discuss belongs to one user
return $this->belongsTo('Users'); // Rename Users to User and use User here
}
Also you should use singular name for all of your models for example, use User instead of Users.
