:)
I've a problem with a relationship in my project, this is the situation, I have two models "Sucursales" and "Checklist", this is the logic... one sucursal can have many checklist, but is one request I only need to get the most recent sucursal's checklist... the simple relation works fine when I call it, but when I'm trying to get the most recent checklist the result is empty, here is the code:
Sucursales Model
class Sucursales extends Model
{
protected $table = 'db_sucursales';
protected $primaryKey = 'id_sucursal';
protected $fillable =['tipo_sucursal', 'no_sucursal', 'id_gcb', 'id_coordinacion', 'nombre_sucursal', 'id_estado', 'direccion_sucursal', 'telefono_sucursal', 'id_estatus'];
public $timestamps = false;
public function checkslist(){
return $this->hasMany(ChecklistSucursal::class, 'id_sucursal','id_sucursal');
}
}
Checklist model:
class ChecklistSucursal extends Model
{
protected $table = 'db_checklist_sucursales';
protected $primaryKey = 'id_checklist';
protected $fillable = [
'folio', 'id_sucursal', 'id_usuario', 'nombre_aplicador', 'encargado_sucursal', 'puesto_encargado_sucursal', 'fecha_aplicacion', 'checklist','estatus','comentarios'
];
public function sucursal(){
return $this->hasOne(Sucursales::class, 'id_sucursal', 'id_sucursal');
}
}
When I call:
$sucursales = Sucursales::with('checkslist')->orderBy('no_sucursal', 'asc')->get();
works fine, but when I call the next code:
$sucursales = Sucursales::with(['checkslist' => function($query){
return $query->latest('fecha_aplicacion');
}])
->orderBy('no_sucursal', 'asc')
->get();
the result is empty...
Please someone can tell me what I'm doing wrong, this project is in laravel 5.5

I've recently started to work with Laravel and I just recently got help to insert the data into multiple tables from one controller. Now I'm trying to retrieve data from the database and populate the form if an edit is needed or if someone needs to look at the data to be able to confirm it is correct. I don't understand how I join the tables is this in the model in Laravel? Or do I have to create a join SQL query?
Travelbill.php Model
<?php
class Travelbill extends Eloquent {
protected $table = 'travelbill';
protected $primaryKey = 'TravelbillId';
protected $fillable = array('ResourceId', 'Destination', 'StartDay', 'StartTime', 'EndDay', 'EndTime', 'Invoice', 'TravelCompensation');
public $timestamps = true;
public function travelbill() {
return $this->belongsTo('User', 'ResourceId', 'ResourceId');
}
public function cost() {
return $this->hasOne('Cost', 'TravelbillId', 'TravelbillId');
}
public function allowance() {
return $this->hasOne('Allowance', 'TravelbillId', 'TravelbillId');
}
}
?>
Cost.php Model
<?php
class Cost extends Eloquent {
protected $table = 'cost';
protected $primaryKey = 'CostId';
// protected $fillable = array('TravelbillId', 'Description', 'DescriptionByHiq', 'SekInklMoms', 'SekExklMoms', 'SekInklMomsByHiq', 'SekExklMomsByHiq', 'Currency', 'ExchangeRate');
protected $fillable = array('TravelbillId', 'Description', 'DescriptionByHiq', 'SekInklMoms', 'SekMoms', 'SekInklMomsByHiq', 'SekMomsByHiq', 'Currency', 'ExchangeRate');
public $timestamps = false;
public function cost() {
return $this->belongsTo('Travelbill', 'TravelbillId', 'TravelbillId');
}
}
?>
Allowance.php Model
<?php
class Allowance extends Eloquent {
protected $table = 'allowance';
protected $primaryKey = 'AllowanceId';
protected $fillable = array('TravelbillId', 'DayAllowance', 'Breakfast', 'Lunch', 'Dinner');
public $timestamps = false;
public function allowance() {
return $this->belongsTo('Travelbill', 'TravelbillId', 'TravelbillId');
}
}
?>
Or where am i doing this join so if i get the travelbill it also gets the Cost and Allowance data with the request?
EDIT:
I need to get the data into my AngularJS form so if a person with id = 1 needs to edit his Travelbill he should be able to click a edit button and see the information ha has filled out.
The simplest form of data retrieval you can do here is to do the following:
$travelBills = Travelbill::with(['code','allowance'])->get();
This is Eager Loading and will perform three queries:
Load all the travel bills
Load all codes that have foreign keys matching all the travelbill ids and assign them to each travel model
Do the same with allowances
What you'll have in the end that every Travelbill model will already have an associated Code and Allowance model, allowing you to work like:
echo $travelBill->cost->SekInklMoms;
for one of the Travelbills you loaded. Note a couple of things in the first query:
The travelbills are not filtered, we are loading them all at this point.
We are doing it simply, not necessarily efficiently. I recommend first get comfortable with the relationships loading before get onto things like joins (which break the spirit of Eloquent ORM in any case)
I have a User-Roles model, using Laravel 4 where a user can have many roles, using Eloquent. I can access all roles linked to a user easily using this code :
class User extends Model {
protected $table = 'user';
protected $fillable = array('name');
public function rolesLinked() {
return $this->hasMany('App\UserRoleLink', 'user_id');
}
}
I've been trying to obtain the roles that are not linked to a user, to display on the specific user's page in a select box. Using this function, included in the User class.
public function rolesNotLinked() {
$user = this
$roles = Roles::whereDoesntHave('App\UserRoleLink',function($query) use ($user){
$query->where('user_id',$user->id);
});
}
The problem is, calling this function gives me the following error.
Call to undefined method Illuminate\Database\Query\Builder::App\UserRoleLink()
I've tried using has with < 1 to see if the function was problematic, but after reading this and the online source code, the function call pretty much does what I've tried.
Is something wrong in my function call, or have I messed up configurations somewhere?
For reference, here are my other Model classes:
class UserRoleLink extends Model{
protected $table = 'user_role_link';
protected $fillable = array('role_id','user_id);
public function role() {
return $this->hasOne('App\Role', 'role_id');
}
}
class Role extends Model{
protected $table = 'role';
protected $fillable = array('name');
}
EDIT: I've found out that I messed up by fillables when I copy-pasted. It didn't fix the issue, but I guess that's one step closer.
To use whereDoesntHave method, you must add the relation in your Role Model.
class Role extends Model{
protected $table = 'role';
protected $fillable = array('name');
public function UserRoles() {
return $this->hasMany('App\UserRoleLink', 'id');
}
}
Also, the whereDoesntHave method first parameter is not thte model but the function of the relation:
public function rolesNotLinked() {
$user = this
$roles = Roles::whereDoesntHave('UserRoles',function($query) use ($user){
$query->where('user_id',$user->id);
});
}
I'm trying to return nested JSON response, need to connect multiple tables, but for now, I'm just trying with 3, the levels can go deeper. My models are following:
Update #1:
class Sport extends Eloquent {
protected $table = 'sportovi';
protected $fillable = ['id', 'sport_eng'];
public $timestamps = false;
public function liga(){
return $this->hasMany('League', 'sport_id');
}
}
class League extends Eloquent {
protected $table = 'lige';
protected $fillable = ['league_id', 'liga', 'sport_id'];
public $timestamps = true;
public function mec(){
return $this->hasMany('Match', 'match_id');
}
}
class Match extends Eloquent {
protected $table = 'mecevi';
protected $fillable = ['match_id', 'home', 'away', 'kotime', 'day', 'kolo', 'sport_id', 'league_id', 'date', 'long_id'];
public $timestamps = false;
public function liga(){
return $this->belongsTo('Match', 'league_id');
}
}
If I do:
$sportovi = Sport::with('liga')->get();
return $sportovi;
everything is normal, children of "lige" are nested where they should be, as shown on the link here, but, if I try to add the Match, like this:
$mecevi = Sport::with('liga.mec')->get();
I get a "mec" node, which is an empty array, as shown here, instead going one level deeper, like in the previous example.
I've also tried making multiple with() conditions which throws an error
Call to undefined method Illuminate\Database\Query\Builder::mec()
Update: Still the same, mec:[], empty array.
I'm using Laravel 4.2.
From my understanding, you want to get all the matches of leagues
The problem might be in the second parameter in hasMany function
public function mec(){
return $this->hasMany('Match', 'league_id');
}
The second parameter need to be foreign_key
public function mec(){
return $this->hasMany('Match', 'match_id', 'league_id');
}
source: http://laravel.com/docs/4.2/eloquent#one-to-many
Figured it out, my table relations were off, after giving all the conditions, like
return $this->hasMany('Comment', 'foreign_key', 'local_key'); everything started working as it should. Thanks everybody.
Hi there i'm trying to sort a collection by attribute of the relation.
This is my model
class Song extends \Eloquent {
protected $fillable = ['title', 'year'];
public function artist(){
return $this->hasOne('Artist','id', 'artist_id');
}
}
class SongDance extends \Eloquent {
protected $table = 'song_dances';
protected $fillable = ['rating'];
public function dance(){
return $this->belongsTo('Dance', 'dance_id');
}
public function song(){
return $this->belongsTo('Song', 'song_id');
}
}
class Dance extends \Eloquent {
protected $fillable = ['name'];
public function song_dances(){
return $this->hasMany('SongDance','dance_id','id');
}
public function songs(){
return $this->belongsToMany('Song', 'song_dances', 'dance_id', 'song_id');
}
}
this is how far i'm by now:
$dance = Dance::find(1);
$songs = $dance->songs()
->with('artist')->whereHas('artist', function ($query) {
$query->where('urlName','LIKE','%robbie%');})
->where('song_dances.rating', '=', $rating)
->orderBy('songs.title','asc')
->where('songs.year', '=', 2012)
->get();
Yeah i just could add a ->sortBy('artist.name'); to the query, but he result-collection can be quite big (about 6000 items) therefore i would prefer a databased sorting.
is there a possibility to do this?
Since Eloquent's relations are all queried separately (not with JOINs), there's no way to achieve what you want in the database layer. The only thing you can do is sort the collection in your app code, which you've already dismissed.
If you feel you must sort it in the database then you should write your own join queries instead of relying on Eloquent's relations.
I am having issues getting the relationship array back when eager loading in laravel 4. for example:
controller:
foreach (Apps::with('extra')->get() as $app)
{
print_r($app->toArray());//returns array but my relationship array at the bottom says null
echo $app->extra; //this will show my relationship details
}
model:
class Apps extends Eloquent
{
protected $connection = 'mysql_2';
protected $table = 'apps';
public $timestamps = false;
protected $primaryKey = 'name';
public function host()
{
return $this->belongsTo('Hosts','name');
}
public function extra()
{
$this->primaryKey='app_ip';
return $this->hasone('Extra','ip');
}
//other functions below.......
}
class Extra extends Eloquent
{
protected $connection = 'mysql_3';
protected $table = 'extra';
public $timestamps = false;
protected $primaryKey = 'ip';
public function app(){
return $this->belongsTo('Apps', 'app_ip');
}
mysql:
My mysql tables were not created through laravel they were previously existent. the app_ip column in the Apps table relates to the ip column in the extra table. it is a 1 to 1 relationship and I have specified the primary key in the relationship function. I am getting relationships back so I know that it is working.
I am able to get relationship data back when I call the function directly, but it does not show the relationship data when I try and print the full array. The main goal is to be able to return both the relationship columns and the app columns in one response.
You need to do this:
$apps = Apps::all();
$apps->load('extra');
foreach ($apps as $app)
{
print_r($app->toArray()); // prints your relationship data as well
}
What you have should work and iterating through the collection or using ->load() to eager load shouldn't make a difference. Are you using the visible restriction on your models? If so you will need to include the relationships.
class Apps extends Eloquent {
protected $visible = array(
'id',
'name',
'created_at',
'extra', // Make the relationship 'visible'
);
public function extra()
{
return $this->hasMany('Extra');
}
}
