Laravel Eloquent::firstOrCreate Problems - php

Ok so I am trying to have use the Eloquent method "firstOrCreate" within another Eloquent model.
FriendRequest Eloquent
class FriendRequest extends Eloquent {
/**
* The database table used by the model.
*
* #var string
*/
public $table = 'requests';
protected $guarded = array('id');
protected $softDelete = true;
public function friend() {
return $this->hasOne('User', 'id', 'friend_id');
}
public function user() {
return $this->hasOne('User', 'id', 'user_id');
}
public function accept() {
// FIRST YOU MUST MARK REQUEST AS ACCEPTED
// THEN SOFT DELETE REQUEST SO IT DOESN'T
// SHOW UP AS ACTIVE FRIEND REQUEST
$this->accepted = '1';
$this->save();
// CREATE FRIENDSHIP USER -> REQUESTED
$friend = Friend::firstOrNew(array('user_id' => Auth::user()->id, 'friend_id' => $this->friend_id));
$friend->save();
// CREATE FRIENDSHIP REQUESTED -> USER
$friend2 = Friend::firstOrNew(array('user_id' => $this->friend_id, 'friend_id' => Auth::user()->id));
$friend2->save();
// SOFT DELETE REQUEST BEING MARKED ACCEPTED
$status = $this->delete();
if (!$status):
return false;
else:
return true;
endif;
}
}
I've tried both firstOrCreate and firstOrNew as shown but with both times 'friend_id' and 'user_id' given in the array are set as '0'.
There is no default on the rows or indexes.
Here's the Friend Eloquent Model
class Friend extends Eloquent {
/**
* The database table used by the model.
*
* #var string
*/
public $table = 'friends';
protected $guarded = array('id');
public function user() {
return $this->hasOne('User', 'id', 'user_id');
}
public function friend() {
return $this->hasOne('User', 'id', 'friend_id');
}
}

The create() method does mass assignment and this is a big security issue, so Laravel has a protection against it. Internally it has guarded = ['*'], so all your columns will be protected against mass assignment. You have some options:
Set the fillable columns of your model:
class User extends Eloquent {
protected $fillable = array('first_name', 'last_name', 'email');
}
Or set only the ones you want to keep guarded:
class User extends Eloquent {
protected $guarded = array('password');
}
You may, at your own risk also do:
class User extends Eloquent {
protected $guarded = array();
}
Also on the difference between the firstorcreate, and firstornew:
The firstOrNew method, like firstOrCreate will attempt to locate a record in the database matching the given attributes. However, if a model is not found, a new model instance will be returned. Note that the model returned by firstOrNew has not yet been persisted to the database. You will need to call save manually to persist it:
You can also go through the Facade and use the follwing:
class Settings extends Eloquent
{
protected $table = 'settings';
protected $primaryKey = 'name';
public static function get($settingName)
{
return Settings::firstOrCreate(array('name' => $settingName));
}
}

I believe you should put your accept() function in one of your controllers instead of the model. I'm not sure how and where you're calling this function, but I think it's in the wrong place.

Laravel: Issue with relationship?

I'm beginning to think why did Laravel implement relationships to their framework, they've never worked for me and their a huge stress to fix when they break. This is the 5th time my relationships are returning null, even when ensuring I've set them up properly?
class UserStats extends Authenticatable
{
protected $table = 'habbo_user_stats';
public $timestamps = false;
protected $guarded = ['id'];
public function user()
{
return $this->belongsTo(User::class, 'id');
}
}
And
class User extends Authenticatable
{
protected $table = 'habbo_users';
public $timestamps = true;
protected $guarded = ['id'];
public function stats() {
return $this->belongsTo(UserStats::class, 'user_id');
}
}
although, when calling
{{ $user->stats->some_column }}
stats is returning null... $user isn't null.
I think you have to define the owner of the relationship too. Ie:
public function stats() {
// $this->hasMany OR $this->hasOne, depending on your use case.
return $this->hasMany(UserStats::class, 'user_id');
}
We need to know here, does the user have many userstats? or the userstats have many user records? what are you planning to do here?
Here are things I noticed about your code
Your database structure is wrong. (need migrations to verify this)
Extending UserStatus from Authenticable
you have guarded id
Your relationships definitions are not correct.
To confirm we would need to look into the database structure and migrations.
If a userstat have many users and a user belongs to 1 userstat.
the migrations will be
users table will have a user_stat_id and userstats table wont have a user_id
the code will look like this.
UserStatus.php
class UserStats extends Model
{
protected $table = 'habbo_user_stats';
public $timestamps = false;
protected $guarded = ['id'];
public function users()
{
return $this->hasMany(User::class, 'user_stat_id');
}
}
User.php
class User extends Authenticatable
{
protected $table = 'habbo_users';
public $timestamps = true;
protected $guarded = ['id'];
public function stat() {
return $this->belongsTo(UserStats::class, 'user_stat_id');
}
}

Laravel 5 eager loading user relationship

I have a User model, the User has a n-n relationship with Widget. The pivot table in this case is called dashboards. The dashboard table has the following columns:
x, y, widget_id and user_id.
I am trying to Eager Load the Dashboard table so that the Front-end can retrieve it while retrieving a User.
My User model essentially looks like this (other relationships excluded):
class User extends Authenticatable implements AuthenticatableUserContract {
use Notifiable, Loggable, SoftDeletes, HasPolicy;
protected $fillable = [
'email',
'role_id',
'permissions',
'disallowed',
];
protected $hidden = [
'google_token',
];
protected $with = [
'widgets', //breaks code
];
public function widgets() {
return $this->belongsToMany(Widget::class, 'dashboards')->withPivot(['x', 'y']);
}
Somehow the protected $with bit breaks the application, preventing the User to be authenticated. It somehow corrupts the User but I have no idea why. I have used protected $with perfectly fine the same way in some other models so I don't think I'm using it wrong.
The error it throws is Call to a member function cannot() on null
Which would refer to this line of code if( Auth::user()->cannot('read', $policyClass ). If I don't put $with in it passes through fine..
HasPolicy.php:
namespace App\Traits;
use Auth;
use Illuminate\Contracts\Auth\Access\Gate;
trait HasPolicy {
protected static function bootHasPolicy() {
static::loaded( function ($model) {
foreach ($model->with as $relation) {
$policyClass = get_class($model->$relation()->getRelated());
if( Auth::user()->cannot('read', $policyClass ) && app(Gate::class)->getPolicyFor($policyClass) ) {
unset($model->with[array_search($relation, $model->with)]);
}
}
});
}
public function newFromBuilder($attributes = [], $connection = null) {
$instance = parent::newFromBuilder($attributes, $connection);
$instance->fireModelEvent('loaded');
return $instance;
}
/**
* Register a loaded model event with the dispatcher.
*
* #param \Closure|string $callback
* #param int $priority
* #return void
*/
public static function loaded($callback) {
static::registerModelEvent('loaded', $callback);
}
}
Why does the $with prevent the User from being Authenticated? What should I be looking at?

Laravel HasOne relationship empty

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.

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 ORM relationship method 'BelongsToMany' throwing error

Summary
I am receiving the following error when trying to call the relationship:
Object of class Illuminate\Database\Eloquent\Relations\BelongsToMany
could not be converted to string
My setup is very basic, and consists of two models, User and Role.
User Model [User.php]
<?php
use Illuminate\Auth\UserInterface;
class User extends Eloquent implements UserInterface {
protected $table = 'users';
protected $hidden = array('password');
protected $fillable = array('id', 'username', 'password');
public function getAuthIdentifier() {
return $this->getKey();
}
public function getAuthPassword() {
return $this->password;
}
}
Role Model [Role.php]
<?php
class Role extends Eloquent {
protected $table = "roles";
protected $fillable = array(
'id',
'code',
'name'
);
public function foo() {
return $this->belongsToMany('User', 'map_role_user', 'role_id', 'user_id');
}
}
And finally I'm calling the method foo in the routes file, example:
Route::get('role', function() {
return Role::find(1)->foo();
});
From
https://laravel.com/docs/5.3/eloquent-relationships or https://laravel.com/docs/4.2/eloquent#relationships
If a collection is cast to a string, it will be returned as JSON:
<?php
$roles = (string) User::find(1)->roles;
If you dont want to add further constraints to the query then you have to use dynamic properties concept. So,
$user = App\User::find(1);
foreach ($user->posts as $post) {
//
}
If you want to add more constraints then do this
App\User::find(1)->posts()->where('title', 'LIKE', '%Best%')->get()
