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');

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'm building a small application on laravel 5.4 where I'm having following models and relationship:
Interaction Model:
public function contactsAssociation()
{
return $this->belongsToMany('App\Contact', 'contact_interaction', 'interaction_id', 'contact_id')->withPivot('company_id')->withTimestamps();
}
Contact Model:
public function company()
{
return $this
->belongsToMany('App\Company', 'company_contact','contact_id', 'company_id')->withTimestamps();
}
and Company Model:
public function contacts()
{
return $this->belongsToMany('App\Contact', 'company_contact', 'company_id','contact_id');
}
Now I'm fetching some data something like this:
$tempData['contacts'] = $interaction->contactsAssociation()->with('company')->get();
I want to extract company data from the pivot table which is mentioned in the relationship. Currently I can't find solution so I have to do:
$tempData['contacts'] = $interaction->contactsAssociation()->get();
$companies = [];
foreach($tempData['contacts'] as $contact)
{
$companies[] = Company::find($contact->pivot->company_id);
}
$tempData['company'] = $companies;
Guide me on this, thanks,
You can pass an array to the withPivot() function with every field you want to retrieve:
public function contactsAssociation()
{
return $this->belongsToMany('App\Contact', 'contact_interaction', 'interaction_id', 'contact_id')
->withPivot(['company_id', 'other_field'])
->withTimestamps();
}
Hope this helps you.
I'm trying to setup some simple favoriting for my app using Laravel/Jenssegers MongoDB
I have two models:
class Item {
public function favorites()
{
return $this->hasMany('App\Models\User', 'favorites');
}
}
class User {
public function favorites()
{
return $this->hasMany('App\Models\Item', 'favorites');
}
}
So an item can have many users and a user can have many items or "favorites".
When I try to run a simple query like:
Item::with('favorites')->get();
The relationship for favorites is there but an empty array.
The favorites table is simple and just has three columns:
_id, item_id, user_id
I've also tried using embedsMany with no luck:
return $this->embedsMany('App\Models\User', 'favorites');
I've also tried every combination of parameters.
return $this->embedsMany('App\Models\User', 'favorites', 'building_id', 'user_id');
return $this->embedsMany('App\Models\User', 'favorites', 'user_id', 'building_id');
return $this->hasMany('App\Models\User', 'favorites', 'building_id', 'user_id');
return $this->hasMany('App\Models\User', 'favorites', 'user_id', 'building_id');
Strange results when using:
return $this->hasMany('App\Models\User', 'favorites', 'building_id', 'user_id');
Only in this situation it returns ALL users, even though favorites has only one record.
Also trying to debug using getQueryLog just gives me an empty array at all times.
print_r(\DB::connection('mongodb')->getQueryLog());
I've done this using mysql and have never had issues. So not really sure where the issues are coming from.
Can you try these instead, I know its the same thing but might do the trick :
use App\User;
use App\Item;
class Item {
public function favorites()
{
return $this->hasMany('User');
}
}
class User {
public function favorites()
{
return $this->hasMany('Item');
}
}
class Favourite {
public function users()
{
return $this->belongsTo('User');
}
public function items()
{
return $this->belongsTo('Item');
}
}
Also add inverse of the above relations like: belongsTo.
and try this query then :
//Just for testing purpose, if raw query returns right result
$items = DB::table('items')
->join('favorites','items.id','=','favorites.id')
->get();
So i'm a bit confused with this situation, I have the current relations:
User hasmany Favourite
favourites references to a Recipe model
favourites is a pivot table but when I retrieve the favourites for a given user like:
$user->favourites
i get the favourite with the pivot data, but I want to get the fields of the recipe
Recipe.php:
public function favourites()
{
return $this->hasMany('App\Favourite');
}
User.php:
public function favourites()
{
return $this->hasMany('App\Favourite');
}
Favourite.php:
public function user()
{
return $this->belongsTo('App\User','user_id');
}
public function recipes()
{
return $this->belongsTo('App\Recipe','recipe_id');
}
EDIT : there was no problem at all, just needed to call:
#foreach($user->favourites as $favourite)
{{ $favourite->recipe->name }}
#endforeach
You need to set your relation to Has Many Through instead of just has Many.
https://laravel.com/docs/5.2/eloquent-relationships#has-many-through
Recipe.php:
public function favourites()
{
return $this->hasManyThrough('App\Favourite', 'App\User');
}
User.php:
public function favourites()
{
return $this->hasManyThrough('App\Favourite', 'App\Receipe');
}
Favourite.php:
public function user()
{
return $this->hasManyThrough('App\User','App\Receipe');
}
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
