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 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 have two data tables related to each other by the belongstomany relationship. And when I am fetching data from its api controllers with selecting only two column keys ['id','title'] yet it returns some extra data in the response object.
modelcode:
public function place(){
return $this->belongsToMany(Place::class,'city_place')->select(array('id', 'title'));
}
controller code:
public function ofcity($id)
{
$city=City::findOrFail($id);
return new CityResource( $city->place()->get());
}
enter image description here
You must indicate the name of the table in front of the fields.
model Place code:
protected $columns = ['places.id', 'places.title']; //all column for select
public function scopeExclude($query, $value = [])
{
return $query->select(\array_diff($this->columns, (array) $value));
}
model City code:
public function place()
{
return $this->belongsToMany(Place::class,'city_place', 'city_id', 'place_id');
}
controller code:
public function ofcity($id)
{
$cities = City::findOrFail($id)->place()->exclude(['featured_image'])->get()->toArray();
return response()->json(['cities' => $cities], 200);
}
In exclude skip all the fields that need not to be shown.
Thanks everyone here helping me out but none of the above solution worked..I figured it out after trying different functions and spending hours on this.
model Place code:
public function place(){
return $this->belongsToMany(Place::class,'city_place','city_id','place_id')->select(array('places.id', 'places.title'));
}
controller code:
public function ofcity($id)
{
$city=City::findOrFail($id);
return new CityResource( $city->place()->get()->map(function ($item,$key) {
return ['id' => $item['id'],'title'=>$item['title']];
})
);
I have a problem about table relationship in models. when I try to add hasMany relation there is an error popping up.
Call to undefined relationship [Plan100] on model [App\AllPlan].
This is the main table model places
protected $table = "places";
public $with = ["AllPlan"];
public function allplans()
{
return $this->hasMany("App\AllPlan");
}
And AllPlan table model
protected $table = "all_plans";
public function place()
{
return $this->belongsTo("App\Place");
}
No problem 'till here. I can see the AllPlan data inside the Places table on json response... But, the problem is popping up when I try to add hasMany relation into AllPlan table like below.
Now AllPlan table model looks like this.
protected $table = "all_plans";
public $with = [
"Plan100",
"Plan90",
];
public function place()
{
return $this->belongsTo("App\Place");
}
public function plan()
{
return $this->hasMany(
"App\Plan100",
"App\Plan90"
);
}
And the Plan100 table model look like this:
public function plan()
{
return $this->belongsTo("App\AllPlan");
}
But it's giving me an error. But I am not very sure where do I do wrong. Thank you.
Seems to me that you are trying to create two new relations, but this can't be done inside one function. Create two functions and refactor your code like this:
public function plan100()
{
return $this->hasMany(App\Plan100", 'foreign_key');
}
public function plan90()
{
return $this->hasMany(App\Plan90", 'foreign_key');
}
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
