So I have tables Uploads and Avtors (Authors). I am trying to write a query that will get me all the uploads for a given user + the author.
To achieve this I have the following function in my controller :
public function uploads()
$uploads = Auth::user()->upload()->with('author')->paginate(10);
return view('uploads')->with('uploads',$uploads);
}
This function manages to get me all the uploads for a given user, but not the author :
When I debug with dd I get this :
My relationships in the models are difined in the following ways :
User:
public function upload(){
return $this->hasMany('App\Upload');
}
Avtor:
class Avtor extends Model
{
public function uploads(){
return $this->hasMany('App\Upload');
}
}
Upload:
public function user(){
return $this->belongsTo('App\User');
}
public function author(){
return $this->belongsTo('App\Avtor');
}
Can anybody help me find out what am I doing wrong here because I can't by myself?
You can use load() method with nested relationship dot syntax:
auht()->user()->load(['uploads', 'uploads.author'])->get();
In this case, you'll not need to pass any data to a view, just do this:
#foreach (auth()->user()->uploads as $upload)
Or you can use with() method:
$uploads = Upload::with('author')->where('user_id', auth()->id())->get();

I am writing a nested query with Laravel.
Namely First, the Truck information is drawn, then I list the data of the vehicle with "truck_history", there is no problem until here, but I want to show the information of the invoice belonging to the "invoice_id" in truck_history. but I couldn't understand how to query, I want to do it in the model, is this possible? If possible, how will it be done?
"ID" COLUMN IN INVOICE TABLE AND "invoice_id" in "InvoiceDetail" match.
TruckController
public function getTruck($id)
{
$truck = Truck::with(['truckHistory'])->find($id);
return $truck;
}
Truck Model
protected $appends = ['company_name'];
public function companys()
{
return $this->belongsTo(Contact::class, 'company_id', 'id');
}
public function getCompanyNameAttribute()
{
return $this->companys()->first()->name;
}
public function truckHistory(){
return $this->hasMany(InvoiceDetail::class,'plate_no','plate');
}
So you can add another relationship in the InvoiceDetail::class and add in the truck history.
try something like this:
public function truckHistory(){
return $this->hasMany(InvoiceDetail::class,'plate_no','plate')->with('Invoice');
}
Simply add the following relations (if you don't already have them):
Invoice model :
public function truckHistory()
{
return $this->hasOne(InvoiceDetail::class);
}
InvoiceDetail model :
public function invoice()
{
return $this->belongsTo(Invoice::class);
}
And you can get the relation invoice of the relation truckHistory adding a point as separator :
public function getTruck($id)
{
$truck = Truck::with(['truckHistory.invoice'])->find($id);
return $truck;
}
I'am new to laravel and had a hard time for eloquent ORM, I like to retrieve Favourite items from the table with specific user id, but seem I don't find a way to display the data correctly.
I refer and copied the favourite model code from here
Model: Favourite
class Favourite extends BaseModel
{
public function favouritable()
{
return $this->morphTo();
}
}
Model: Course
public function favourites()
{
return $this->morphMany(Favourite::class, 'favouritable');
}
public function myFavourite()
{
return $this->favourites()->where('favor_user', '=', auth()->user()->id);
}
Controller: FavouriteController#index
public function index()
{
$course = new Course();
$myfavs = $course->myFavourite();
//dd($myfavs);
$this->vdata(compact('myfavs'));
return view('front.favorites', $this->vdata);
}
In blade view, but return empty/blank data:
#foreach($myfavs as $myfav)
{{ $myfav->$course_name }}
#endforeach
When i dd($myfavs) it display pretty bunches of data that i couldn't find the data that is stored in the favourites table.
I think you have added the conditions but forgot get the results with one of the methods to do so.
Try :
$myfavs = $course->myFavourite()->get();
Or :
$myfavs = $course->myFavourite()->take(<N>)->get;
Or
::all()
etc. take a look at : https://laravel.com/docs/5.8/eloquent#retrieving-models
I have a project with main table 'Qsos' and bunch of relations. Now when I try to create advanced search I don't really know how to query all relations at the same time. Qso model has following:
public function band()
{
return $this->belongsTo('Band');
}
public function mode()
{
return $this->belongsTo('Mode');
}
public function prefixes()
{
return $this->belongsToMany('Prefix');
}
public function user()
{
return $this->belongsTo('User');
}
public function customization() {
return $this->hasOne('Customization');
}
Then I have SearchController with following code that has to return collection of all Qsos following required conditions:
$qsos = Qso::withUser($currentUser->id)
->join('prefix_qso','qsos.id','=','prefix_qso.qso_id')
->join('prefixes','prefixes.id','=','prefix_qso.prefix_id')
->where('prefixes.territory','like',$qTerritory)
->withBand($qBand)
->withMode($qMode)
->where('call','like','%'.$input['qCall'].'%')
->orderBy('qsos.id','DESC')
->paginate('20');
And then in view I need to call $qso->prefixes->first() and $qso->prefixes->last() (Qso and Prefix has manyToMany relation) but both return null. What is wrong?
Here is the eloquent code that I found working but taking VERY long time to process:
$qsos = Qso::withUser($currentUser->id)
->with('prefixes')
->withBand($qBand)
->withMode($qMode)
->where('call','like','%'.$input['qCall'].'%')
->whereHas('prefixes', function($q) use ($qTerritory) {
$q->where('territory','like',$qTerritory);
})
->orderBy('qsos.id','DESC')
->paginate('20');
hi sorry bit of a newbie here but I am have three tables users, profiles, friends. they all have the user_id fields within them and I want fetch all of the fields in one statement using Eloquent and not DB::statement and doing the table joins.
How can I achieve this?
Try this
use the User class and the with method that laravel has to query model relationships
$user = User::with(['profile', 'friend'])->get();
Ensure your models has the correct relationships as follows:
app/models/User.php
public function friend () {
return $this->hasMany('Friend');
}
public function profile () {
return $this->hasOne('Profile');
}
app/models/Profile.php
public function user() {
return $this->belongsTo('User');
}
app/models/Friend.php
public function user() {
return $this->belongsTo('User');
}
use some thing like this:
You should define relations in your models with hasOne, hasMany.
class Review extends Eloquent {
public function relatedGallery()
{
$this->hasOne('Gallery', 'foreign_id', 'local_id');
}
}
class Gallery extends Eloquent {
public function relatedReviews()
{
$this->hasMany('Review', 'foreign_id', 'local_id');
}
}
$gallery = Gallery::with('relatedReviews')->find($id);
Will bring the object Gallery with
$gallery->id
gallery->name
...
$gallery->relatedReviews // array containing the related Review Objects
My "user" model with a has-many relationship to an "image" model.
Returning just the user is as easy as "return Response::eloquent($user);". I'd like to either return a JSON array of
{user: {id:…}, images: [{id:…},{id:…}]}
or, perhaps better,
{id:…, images: [{id:…},{id:…}]}
What's the best way to arrange and ship these models? Should I
The first thing you'll need to do is make sure your models are set up correctly:
class Users extends Eloquent {
public function images()
{
return $this->hasMany('Image');
}
}
class Image extends Eloquent {
public function user()
{
return $this->belongsTo('User');
}
}
Then in your route you should be able to do something like:
Route::any('userinfo/{$userId}', function($userId)
{
return Response::json(User::with('images')->find($userId));
//or
return User::with('images')->find($userId)->toJson();
});
