I have the following relationship in User.
public function partner()
{
return $this->hasOne('App\Partner','partner_id');
}
And I am accessing that relationship
auth()->user()->partner()->name
But it gives me exception where name is available in partners table:
Undefined property: Illuminate\Database\Eloquent\Relations\HasOne::$name`
And the user object from auth()->user()->partner() is also empty.
What am I missing?
auth()->user()->partner() returns the relation binding, not the model itself.
try auth()->user()->partner->name instead.
First, ensure you setup the right relationship:
User.php
public function partner()
{
return $this->hasOne('App\Partner');
}
Partner.php
public function user()
{
return $this->belongsTo('App\User');
}
To access the user's partner:
// Get the user's Partner instance:
$partner = auth()->user()->partner;
// Access the user's partner properties:
$partner_name = auth()->user()->partner->name;
Also, check that your partners table has the column user_id.
I think you are doing it wrong, All you have to do is that to change :
public function partner()
{
return $this->hasOne('App\Partner','partner_id');
}
to
public function partner()
{
return $this->belongsTo('App\Partner');
}
A user belongs to a partner, Cause partner is a meta table.

i have a relation between User model and Friend model
User.php
public function friends()
{
return $this->hasMany(Friend::class);
}
the relation actually returns all the records where the foreign key column (user_id) between User and Friend equals the current user's id but i want to return also the records where current user's id is in another column in friends table which's name is friend_id, this is my try
public function friends()
{
return $this->hasMany(Friend::class,'user_id','friend_id');
}
it's actually not returning the correct records
I don't think there is a direct way to that but you could try making 2 relations and merge them into one relation
public function friends() {
return $this->hasMany(Friend::class);
}
public function additionalfriends() {
return $this->hasMany(Friend::class, 'friend_id');
}
public function allfreinds() {
return $this->friends->merge($this->additionalfriends);
}
another solution you might try is
public function friends()
{
return Friend::where(function($query) {
$query->where('user_id',$this->id)
->orWhere('friend_id',$this->id);
});
}
So I am setting up a one to one relationship between MyModel and the users table.
MyModel obviously has a user_id column to tie back to the users.
However - when i go to setup the relationship in MyModel I have to set it up in a way which seems backward!
This is in MyModel:
public function user()
{
return $this->hasOne('App\User', 'id', 'user_id');
}
Why Am i having to set the opposite foreign and local keys... ? Am i missing something?
Do it like this
class MyModel {
public function user()
{
return $this->belongsTo('App\User');
}
}
class User {
public function myModel()
{
return $this->hasOne('App\MyModel');
}
}
And that should work as intended (one to one) relationship
I have 3 models: User, Role and Currency. I am confused about relationship between them.
Then User is Admin this works:
Auth::user()->currency->symbol)
When regular User I get error:
Trying to get property of non-object
if dd(Auth::user()) it show user, but cant access to relationship with model Currency. Why it is so?
User model relationship:
public function currency()
{
return $this->belongsTo(Currency::class, 'currency_id');
}
Currency model relationship:
public function created_by()
{
return $this->belongsTo(User::class, 'created_by_id');
}
If you need extra information, let me know.
User model
public function currency()
{
return $this->belongsTo(Currency::class);
}
Currency model
public function users()
{
return $this->hasMany(User::class, 'created_by_id');
}
Going with an assumption that your User model has an attribute currency_id
$this->belongsTo(TABLE, FORIEGN KEY, TABLE KEY);
refer this
User model
public function currency()
{
return $this->belongsTo(Currency::class, 'currency_id', 'id');
}
Currency model
public function users()
{
return $this->hasMany(User::class, 'created_by_id', 'id');
}
My project is working fine on local host, but on the server, getting error only on lesson page.
Subject Model is
class Subjects extends Model
{
public function category()
{
return $this->belongsTo('Lea\Category');
}
public function lesson()
{
return $this->hasMany('Lea\Lessons');
}
public function chapter()
{
return $this->hasMany('Lea\Chapters');
}
public function users()
{
return $this->belongsToMany('Lea\User', 'subject_user', 'subject_id', 'user_id');
}
}
And Lesson Model is
class Lessons extends Model
{
public function chapter()
{
return $this->belongsTo('Lea\Chapters');
}
public function subject()
{
return $this->belongsTo('Lea\Subjects', 'subject_id');
}
public function category()
{
return $this->belongsTo('Lea\Category');
}
}
My controller lessons has method index like below.
public function index()
{
$lessons = lessons::orderBy('id', 'asc')->paginate(5);
return view('admin.lessons.index')->withLessons($lessons);
}
The way i am calling subject name is show below. first subject is relationship subject and 2nd subject is the field name where subject name saved in db. using foreach to get data like:
#foreach ($lessons as $lesson)
{{$lesson->subject->subject}}
#endforeach
subjects table schema is
id
subject
admin_id
users_id
category_id
created_at
updated_at
lessons table schema is
id
title
slug
category_id
subject_id
chapter_id
users_id
content
image
That's more like it ;)
Just edit how you are passing the object to the following:
...
return view('admin.lessons.index')->with(compact('lessons'));
What this is doing:
compact() essentially takes the object/variable by it's name ($lessons) and passes it to the view with the same name.
An alternative way is to write it as:
...
return view('admin.lessons.index')->with('lessons', $lessons);
Cheers!
The reason you're getting the error in your server but not your local machine is that your server database is empty (or at least has fewer records).
{{$lesson->subject->subject}}
The lesson has no subject, so it's null. And your tryting to get a proprty subject of a null.
If you're using Laravel 5.5, you can wrap the subject in optional() method.
{{optional($lesson->subject)->subject}}
< Laravel 5.5
{{$lesson->subject ? $lesson->subject->subject : ''}}
I have read a few topics about this, but they managed to solve my problem partially ...
this is my controller
class DeskController extends BaseController{
public function getDeskUsers($deskId){
$user = DeskUserList::where(function($query) use ($deskId){
$query->where('deskId', $deskId);
})->with('userName')->get(array('deskId'));
if (!$user->isEmpty())
return $user;
return 'fail';
}
this is the model
class DeskUserList extends Eloquent {
protected $table = 'desk_user_lists';
public function userName(){
return $this->belongsTo('User', 'userId')->select(array('id','userName'));
}
}
the method getDeskUsers may returns ALL the DeskUserList table records, related with the User table record (on deskUserList.userId = User.id).
practically I want each record returned is composed of:
DeskUserList.deskId
User.userName
eg. [{"deskId":"1","user_name":antonio}]
What i get is
[{"deskId":"1","user_name":null}]
As you can see the user name is a null value...
BUT
if I edit my controller code:
->with('userName')->get(array('userId')); //using userId rather than deskId
then i get
[{"userId":"2","user_name":{"id":"2","userName":"antonio"}}]
By this way I still have two problem:
the userId field is twice repeated
I miss the deskId field (that I need...)
hope be clear, thanks for your time!
You need belongsToMany, no need for a model representing that pivot table.
I assume your models are Desk and User:
// Desk model
public function users()
{
return $this->belongsToMany('User', 'desk_user_list', 'deskId', 'userId');
}
// User model
public function desks()
{
return $this->belongsToMany('Desk', 'desk_user_list', 'userId', 'deskId');
}
Then:
$desks = Desk::with('users')->get(); // collection of desks with related users
foreach ($desks as $desk)
{
$desk->users; // collection of users for particular desk
}
// or for single desk with id 5
$desk = Desk::with('users')->find(5);
$desk->users; // collection of users
$desk->users->first(); // single User model
