I want to pull the invoice detail with the "id" number of 3 in the tools table from the "invoice_details" table. "plate" "invoice_details" relationship "plate_no" in the "trucks" table, but when I pull the data, a different data is coming, where am I making a mistake?
public function getTruck($id)
{
$truck = Truck::find($id)->with(['truckHistory'])->first();
return $truck;
}
Truck extends Model
public function truckHistory(){
return $this->hasMany(InvoiceDetail::class,'plate_no','plate');
}
Normally the incoming data is TRUE when I don't write a with condition
THIS IS TRUE
$truck = Truck::find(3);
{
"id": 3,
"plate": "73AD323",
"created_at": "2021-10-13T08:38:23.000000Z",
"updated_at": "2021-10-13T08:38:23.000000Z"
}
When I type a condition, the id is wrong.
$truck = Truck::find(3)->with(['truckHistory'])->first();
{
"id": 1,
"plate": "33EER36",
"created_at": "2021-10-11T06:01:29.000000Z",
"updated_at": "2021-10-11T06:01:29.000000Z",
"truck_history": [
{
"id": 1,
"plate_no": "33EER36",
"created_at": "2021-10-11T06:03:16.000000Z",
"updated_at": "2021-10-11T06:03:16.000000Z"
},
{
"id": 2,
"plate_no": "33EER36",
"created_at": "2021-10-11T06:06:18.000000Z",
"updated_at": "2021-10-11T06:06:18.000000Z"
}
]
}
Using first will return the first record of the trucks table, to do so you can use
Truck::with(['truckHistory'])->find($id);

CONTEXT
in a relationship many to many, i have 3 tables
Avisos
Avisos_estados (Intermediate Table)
Estados
and the models:
Model Aviso:
public function estados(){
return $this->belongsToMany(Estado::class,'avisos_estados','estados_id','avisos_id')->withPivot('activo','created_at')->wherePivot('activo', 1);
}
Model Estado:
public function avisos(){
return $this->belongsToMany(Aviso::class,'avisos_estados','avisos_id','estados_id')->withPivot('activo','created_at');
}
The issue:
When i try to get the Aviso where id =1, with state (estados where activo =1)
My eloquent query:
$id=1;
$aviso = Avisos::select(
'Avisos.id',
'Avisos.titulo',
'Avisos.descripcion',
'Avisos.imagen',
'Avisos.created_at as fecha',
'Avisos.vistas',
'users.id as idUsuario',
'users.name',
'comunas.nombreComuna',
'ciudads.nombreCiudad'
)->join('categorias','categorias.id', '=','avisos.idCategoria')
->join('estados','estados.id', '=','avisos.idEstado')
->join('users','users.id', '=','avisos.idUsuario')
->join('comunas','comunas.id','=','avisos.idComuna')
->join('ciudads', 'ciudads.id','=','comunas.idCiudad')
->with('valoraciones')
->find($id);
//Aca uso el modelo para traer los estados y usuarios relacionados con el aviso
$aviso->users;
$aviso->estados;
The response has some states that has not relation with aviso.id=1
Response (just the important part) Complete response
"estados": [//these are the states in the response

"avisos_id": 1,
"activo": 1,//With pivot only get where activo =1
"created_at": "2022-09-08T17:05:17.000000Z"
}
}
]
the question: is there something worng with my model relationship?, or should i use some filter in my query?
Structure many to many
table estados (abierta = open, cerrada=closed,desierta=deserted, eliminada= deleted)
all states where aviso.id=1
as you can see, when i create the aviso this has a default state (open), but later change the state to closed, for that reason the record with description "Abierta (open)" has activo=0
Let me make it simple, In my models, I have countries and cities. My goal is, I want to select and display only the cities that has shops and it should also have datas and the employees should not be NULL
In the below given array, my city has two shops where id - 13 that doesn't have any datas and id - 19 which is having data.
[
{
"id": 1,
"created_at": "2022-06-02T06:07:31.000000Z",
"updated_at": "2022-06-02T06:07:31.000000Z",
"name": "Niue",
"cities": [
{
"id": 13,
"created_at": "2022-06-02T06:07:44.000000Z",
"updated_at": "2022-06-02T06:07:44.000000Z",
"country_id": 1,
"name": "North Michealbury",
"shops": [] //empty
},
{
"id": 19,
"created_at": "2022-06-02T06:07:44.000000Z",
"updated_at": "2022-06-02T06:07:44.000000Z",
"country_id": 1,
"name": "Millsmouth",
"shops": [
{
"id": 1,
"created_at": "2022-06-02T06:14:37.000000Z",
"updated_at": "2022-06-02T06:14:37.000000Z",
"city_id": 19,
"name": "Roberts-Okuneva",
"employees_count": 146
}
]
}
]
}
]
This is the code that, I have written in my controller. The goal is, I want to select and show only those cities that has shops with employees.
return Country::with(['cities','cities.shops'=>function($employee){
$employee->withCount('employees')->where('city_id',19);
}])->whereHas('cities',function($city){
$city->where('cities.id',19);
})->get();
These are my models, each of them has a hasMany relationship
Country model
public function Cities(){
return $this->hasMany(City::class);
}
City model
public function shops(){
return $this->hasMany(Shop::class);
}
Shop model
public function employees(){
return $this->belongsToMany(User::class,'shop_employees','shop_id','employee_id');
}
You can try
//Get all cities which have shops having at least one employee
return Country::with([
'cities',
'cities.shops' => function($query) {
$query->withCount('employees');
}
])
->whereHas('cities', function($query) {
$query->whereHas('shops', function($query) {
$query->has('employees');
});
})
->get();
i found another solution querying with clause.
return Country::whereHas('cities',function($cities){
$cities->where('country_id',1);
})->with(['cities'=>function($shops){
$shops->has('shops')->where('cities.country_id',1);
},'cities.shops'=>function($employee){
$employee->withCount('employees');
}])->get();
I have 3 tables - users, graduation_institutes, graduation_degrees
I defined a pivot table - graduation_degree_user
graduation_degree_user table has data like below -
id--------doctor_id--------graduation_degree_id----------graduation_institute_id---------year
In my User model, I defined relation like below -
public function graduations(){
return $this->belongsToMany('App\Models\User\GraduationDegree')->withTimestamps();
}
In my controller, I m doing -
if($request->has('graduations')){
$user->graduations()->sync($request->graduations);
}
return $user->graduations;
Where graduations is an array which contains multiple object.
I am getting the following response -
[
{
"id": 3,
"degree": "MD",
"created_at": null,
"updated_at": null,
"pivot": {
"user_id": 2,
"graduation_degree_id": 3,
"graduation_institute_id": 1,
"created_at": "2020-12-01T07:54:23.000000Z",
"updated_at": "2020-12-01T07:54:23.000000Z"
}
},
{
"id": 4,
"degree": "MBBS",
"created_at": null,
"updated_at": null,
"pivot": {
"user_id": 2,
"graduation_degree_id": 4,
"graduation_institute_id": 2,
"created_at": "2020-12-01T07:54:24.000000Z",
"updated_at": "2020-12-01T07:54:24.000000Z"
}
}
]
In response, I am getting graduation_institute_id but I also want the name of the institute which is a field 'institute' defined in graduation_institutes table.
I have a table user_childrens whose contains id_parent and id_user.
I'm trying to list all childrens of the parent with this:
code:
//relation in model via belongsTo
$idparent = auth('api')->user()->id;
$list = UserChildren::where('id_parent',$idparent)
->with('child:id,name,email')
->get();
return $list->toJson();
The return is:
[
{
"id": 1,
"id_parent": 1,
"id_user": 1,
"created_at": null,
"updated_at": null,
"child": {
"id": 1,
"name": "Mr. Davin Conroy Sr.",
"email": "prempel#example.com"
}
},
{
"id": 4,
"id_parent": 1,
"id_user": 2,
"created_at": null,
"updated_at": null,
"child": {
"id": 2,
"name": "Krystel Lehner",
"email": "cernser#example.net"
}
}
]
But it's API so I want only the child column like:
[
{
"id": 1,
"name": "Mr. Davin Conroy Sr.",
"email": "prempel#example.com"
},
{..}
]
UserChildren Model:
public function child() {
return $this->belongsTo('App\User','id_user','id');
}
I know that I could do this via .map() on collection but maybe there is other solution already on this query
You can use this code
$idparent = auth('api')->user()->id;
$childs = User::whereHas('user_childrens', function ($query) use ($idparent) {
$query->where('id_parent', $idparent);
})->get(['id', 'name', 'email']);
dd($childs->toJson());
And User model define user_childrens relation.
public function user_childrens()
{
return $this->hasMany('App\UserChildren','id_user','id');
}

The platform has a many to many relationship, where the table assigned_users holds all Users assigned to CalendarEvents.
I need to fetch, through CalendarEvents, the assigned users as an object, showing each user's information. So, I want to access the User through AssignedUsers, because I wanna fetch all the users related to that event.
public function assignedUsers()
{
return $this->hasManyThrough(Users::class, AssignedUsers::class, 'user_id', 'id');
}
It works, but it shows only the first user in the table. I want to show all of them. Currently there are 3.
"assigned_users": [
{ id: 1, ... }
]
If I do the following:
public function assignedUsers()
{
return $this->belongsToMany(Users::class, "assigned_users", "event_id", "event_id");
}
It will fetch 3 results, but all the information will be from the same user. It will repeat the same user 3 times. Changing both the event_id to user_id and id, and id and user_id will have the same result.
"assigned_users": [
{ id: 1, ... },
{ id: 1, ... },
{ id: 1, ... },
...
]
What I am trying to accomplish is the following result:
{
"status": "200",
"success": true,
"data": [
{
"event_id": 1,
"event_key": "EB1M7OGJRPW0",
"calendar_id": 4,
"start_at": "2018-01-01 00:00:00",
"end_at": "2018-01-31 00:00:00",
"location": "123 Lorem, Ipsum",
"event_name": "Event #1",
"description": "Lorem ipsum dolor sit amet",
"added_at": "2018-02-07 09:07:31",
"created_by": {
"id": 4,
"name": "Foo Bar",
"email": "foobar92#gmail.com",
"first_name": "Foo",
"last_name": "Bar",
"status": "active",
"is_activated": 0,
"created_at": "2018-02-07 09:06:49",
"updated_at": "2018-02-07 09:06:49"
},
"assigned_users": [
{
"id": 1,
...
},
{
"id": 2,
...
},
{
"id": 3,
...
},
...
]
}
]
}
This is not the case of hasManyThrough relationship. Here assigned_users is a pivot table so you just need a belongsToMany relationship defined
public function assignedUsers()
{
return $this->belongsToMany(Users::class, 'assigned_users', 'event_id', 'user_id');
}
and for this to work, you may have to change the calendar_events table's primary key to id (instead of event_id)
