Hello so I have many to many relation between Question [table name: tblquestion, id: que_id] and Agecategory [table name: tblagecategory, id: aca_id]. They have shared table named QuestionAgecategory [table name: tblquestionagecategory, id: qac_id].
I want to note that all the IDS and table names are custom named and not according to typical Laravel syntax.
And I am trying to relate them in Laravel. So far it returns null when I try to look $question->agecategories;
$question->agecategories;
=> null
But it has records in it and returns this after $question = App\Question::find(1);
$question = App\Question::find(1);
=> App\Question {#2901
que_id: 1,
que_name: "hello",
Question model
class Question extends Model
{
protected $table = 'tblquestion';
protected $primaryKey = 'que_id';
protected $keyType = 'integer';
public $incrementing = true;
public $timestamps = false;
public function agecategories()
{
return $this->belongsToMany('App\Agecategory');
}
}
Agecategory model
class Agecategory extends Model
{
protected $table = 'tblagecategory';
protected $primaryKey = 'aca_id';
protected $keyType = 'integer';
public $incrementing = true;
public function questions()
{
return $this->belongsToMany('App\Question');
}
}
QuestionAgecategory model
class QuestionAgecategory extends Model
{
protected $table = 'tblquestionagecategory';
protected $primaryKey = 'qac_id';
protected $keyType = 'integer';
public $incrementing = true;
}
Migrations
Schema::create('tblquestion', function (Blueprint $table) {
$table->increments('que_id');
$table->string('que_name', 128);
});
Schema::create('tblagecategory', function (Blueprint $table) {
$table->increments('aca_id');
$table->timestamps();
});
Schema::create('tblquestionagecategory', function (Blueprint $table) {
$table->increments('qac_id');
$table->integer('qac_que_id')->unsigned();
$table->integer('qac_aca_id')->unsigned();
$table->foreign('qac_que_id')->references('que_id')->on('tblquestion');
$table->foreign('qac_aca_id')->references('aca_id')->on('tblagecategory');
});
You are using custom columns and custom database naming.
Your Belongs to many is expecting a pivot table tblquestion_tblagecategory which does not exist. As the previos answer stated, you should change your belongsToMany to search for the custom tables and columns.
https://laravel.com/docs/5.6/eloquent-relationships#many-to-many
Change to this in your question Model
public function agecategories()
{
return $this->belongsToMany('App\Agecategory', 'tblquestionagecategory', 'qac_que_id', 'qac_aca_id');
}
And also, in your other Agecategory Model
public function questions()
{
return $this->belongsToMany('App\Question', 'tblquestionagecategory', 'qac_aca_id', 'qac_que_id');
}
add below relationship function in Question model
public function agecategories()
{
return $this->belongsToMany('App\Agecategory', 'tblquestionagecategory', 'qac_que_id', 'qac_aca_id');
}
I encountered the same problem but I had to declare only the foreign keys without a prefix like this:
public function agecategories()
{
return $this->belongsToMany('App\Agecategory', 'tblquestionagecategory', 'que_id', 'aca_id');
}

Im trying to store more than one product with my controller. In my function store first i generate a ticket and then i generate a product_ticket with the ticket_id recently generated and the product_id from the selected product from the form. But how can i do to store more than one if i select more than one product in the form.
This are my relationships:
Product.php:
class Product extends Model
{
public function tickets()
{
return $this->belongsToMany(Ticket::class);
}
public function productXticket()
{
return $this->hasMany(ProductXTicket::class);
}
}
Ticket.php
class Ticket extends Model
{
public function productXticket()
{
return $this->hasMany(ProductXTicket::class);
}
public function products()
{
return $this->belongsToMany(Product::class);
}
}
ProductXTicket:
class ProductXTicket extends Model
{
protected $table = 'product_ticket';
public function ticket_id(){
return $this->belongsTo(Ticket::class);
}
public function product_id(){
return $this->belongsTo(Product::class);
}
}
product_ticket migration:
Schema::create('product_ticket', function (Blueprint $table) {
$table->id();
$table->foreignId('product_id')->constrained();
$table->foreignId('ticket_id')->constrained();
$table->string('serial_number');
$table->integer('quantity');
$table->timestamps();
});
}
TicketController:
public function store(Request $request){
/*dd($request->all());*/
$ticket = new Ticket();
/*$ticket->cuenta_id = $request->cuenta_id;*/
$ticket->contact_id = $request->contact_id;
$ticket->statusTicket_id = $request->statusTicket_id;
$ticket->typeTicket_id = $request->typeTicket_id;
$ticket->idOwner = Auth::user()->id;
$ticket->save();
$productXticket = new ProductXTicket();
$productXticket->ticket_id = $ticket->id;
$productXticket->serial_number = $request->serial_number;
$productXticket->quantity = $request->quantity;
$ticket->productXticket()->save($productXticket);
Session::flash('success');
return redirect()->route('tickets.view');
}
So here im storing one ticket and one product_ticket. I want form each ticket to store the same amount of product_ticket as the amount products selected
Instead of:
$ticket->productXticket()->save($productXticket);
Use:
$ticket->productXticket()->saveMany([$productXticket,...]);

return view('transaksi.supplier', compact('transaksi'));
}
this is my database, the "metode_id" get null, how i want that "metode_id" is not null :
enter image description here
If you try to update a belongsTo relationship, you have to use the associate method instead of save method.
...
$metode = new Metode();
$metode->bni = $request->bni;
$metode->save();
$transaksi->metode()->associate($metode);
$transaksi->save();
...
If you try to SaveMethod in the belongsTo relationship.

I've been tring for hours to define my relations for a completion system but I failed.
I have a table Users and a table Episodes, and I would like to get in my views if the User has completed an episode.
I created a "completions" table with user_id and episode_id and a boolean field called "completed"
Is it a manytomany relation ? I'd like to have something like $episode->completed which gave me True if the logged in user finished the course, but I can't find my way... I just wanna know how to define my relations, not a whole work done.
Thank you very much !!!!
I believe you can tell Laravel what table to use and also query the pivot column.
//user model
public function episodes(){
return $this->belongsToMany( 'App\Episode', 'completions', 'user_id', 'episode_id' );
}
public function completedEpisodes(){
return $this->belongsToMany( 'App\Episode', 'completions', 'user_id', 'episode_id' )
->wherePivot('completed','=', true)->get();
}
//episode model
public function users(){
return $this->belongsToMany( 'App\User', 'completions', 'episode_id', 'user_id' );
}
The alternative would be to create your pivot as episode_user and laravel will auto detect it as the pivot, add a completed boolean to that table and it would function with just:
//user model
public function episodes(){
return $this->belongsToMany('App\Episode');
}
public function completedEpisodes(){
return $this->belongsToMany('App\Episode')
->wherePivot('completed','=', true)->get();
}
//episode model
public function users(){
return $this->belongsToMany('App\User');
}
Query if episode is complete:
//maybe, haven't tried this
//user
public function hasCompletedEpisode($id){
return $this->belongsToMany('App\Episode')->wherePivot('episode_id','=', $id)
->wherePivot('completed','=', true)->get();
}
//episode
public function hasCompletedEpisode($id){
$user_id = Auth::id();
return $this->belongsToMany('App\User')->wherePivot('user_id','=', $user_id)
->wherePivot('completed', true)->get();
}
If I was you, I would use a custom intermediate table. You can implement this as follows:
Migrations
Schema::create('users', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('name');
$table->timestamps();
});
Schema::create('episodes', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('name');
$table->timestamps();
});
Schema::create('watches', function (Blueprint $table) {
$table->bigIncrements('id');
$table->unsignedBigInteger('user_id');
$table->unsignedBigInteger('epsiode_id');
$table->boolean('completed');
$table->timestamps();
});
Models
class User extends Model
{
protected $guarded = [];
public function watchedEpisodes()
{
return $this->hasMany(Episode::class)->using(Watch::class);
}
public function watches()
{
return $this->hasMany(Watch::class);
}
}
class Episode extends Model
{
protected $guarded = [];
public function users()
{
return $this->hasMany(User::class)->using(Watch::class);
}
}
class Watch extends \Illuminate\Database\Eloquent\Relations\Pivot
{
protected $table = 'watches';
protected $guarded = [];
public static function create(User $user, Episode $episode, bool $completed = false)
{
$watch = new self();
$watch->user_id = $user->id;
$watch->epsiode_id = $episode->id;
$watch->completed = $completed;
$watch->save();
return $watch;
}
public function user()
{
return $this->hasOne(User::class);
}
public function episode()
{
return $this->hasOne(User::class);
}
}
Example Use
$user = User::create(['name' => 'Big Watcher']);
$episode1 = Episode::create(['name' => 'Episode 1']);
$episode2 = Episode::create(['name' => 'Episode 2']);
$episode3 = Episode::create(['name' => 'Episode 3']);
$episode4 = Episode::create(['name' => 'Episode 4']);
Watch::create($user, $episode1);
Watch::create($user, $episode2);
Watch::create($user, $episode3);
return $user->watchedEpisodes;

please help me, i tried with many tutorial relational laravel but it's not working for me. i dont know where my false, please tell me my false.
*note: sorry for bad english
You've to define your foreign key in relationship.
public function category(){
return $this->belongsTo(Category::class,'id_category','id');
}
public function pets_category(){
return $this->belongsTo(PetsCategory::class,'id_pets_category','id');
}
If you don't pass the foreign key then by default it judges 'category_id' or 'pets_category_id' but you've given id_category and id_pets_category
I want to populate Every CustomerEvent with the Customer related to the CustomerEvent.
When I Loop through the object and call to $customerevent->customer foreach object I can get the customer related to that event but Can I populate the all objects in the main object without looping through every single event ?
I want to do something like this:
$typeOne = CustomerEvent::typeOne()->get();
$customersWithTypeOne = $typeOne->Customers;
Here my code:
Table 1: "events"
id, customer_id
Model for Table 1 "CustomerEvent":
<?php
class CustomerEvent extends Eloquent{
protected $guarded = ['id'];
public $table = "event";
protected $softDelete = true;
public function scopeTypeOne($query)
{
$followUps = $query->where('type_id', '=', '1');
}
public function Customers()
{
return $this->belongsTo('Customer', 'customer_id');
}
}
Table 2: "customers"
id
Model for Table 2 "Customers":
<?php class Customer extends BaseModel{
protected $guarded = ['id'];
}
EventController:
public function index()
{
$typeOne = CustomerEvent::typeOne()->get();
$customersWithTypeOne = $typeOne->Customers;
dd($customersWithTypeOne);
}
From you database scheme I see customer has many events, so I would recommend to define this relationship in you Customer model.
class Customer extends BaseModel{
protected $guarded = ['id'];
public function events()
{
return $this->hasMany('CustomerEvent', 'customer_id');
}
}
Then you will be able to query customers with events:
$customersWithTypeOne = Customer::whereHas('events', function($query){
$query->where('type_id', 1);
})->get()
Maybe Ardent can help you: https://github.com/laravelbook/ardent
It's an extension for Eloquent models and very popular.
