Alright so I am basically trying to retrieve all animal_registry codes based on a user ID.
Idea is that
1 user has many jobs.
Jobs are consisted of many "Jobs data".
Jobs data has many "Animal registry" entries.
These are my relations
Image relations link (click)
And these are my relations in Laravel
class User
{
public function jobs()
{
return $this->hasMany('App\Models\RegistryJobs', 'employee', 'id');
}
}
class RegistryJobs extends Model
{
protected $table = "registry_jobs";
protected function jobsData()
{
$this->hasManyThrough('App\Models\AnimalRegistry', 'App\Models\RegistryJobsData', 'id', 'animal_registry_id');
}
}
class RegistryJobsData extends Model
{
protected $table = "registry_jobs_data";
public function jobs()
{
$this->belongsTo('App\Models\RegistryJobs', 'id', 'registry_jobs_id');
}
public function animals()
{
$this->hasMany('App\AnimalRegistry', 'id', 'animal_registry_id');
}
}
class AnimalRegistry extends Model
{
protected $table = "animal_registry";
}
And now I am trying to query it from a controller in a way
$data = User::whereHas('jobs', function ($query) {
$query->where('id', 1);
})->get();
But I am unable to access the properties from the animal_registry.
Can you try like this :
public function animals(){
return $this->hasManyThrough('App\Registry_Jobs_data','App\Registry_Jobs', 'employee',
'registry_jobs_id', 'id' ,'id')->join('//Do the joining')->select();
}
Check the hasManyThrough i am not sure..

I would like to store the corresponding logged in user when adding a new School data. What I'm trying to do is store the logged in user_id in the schools table, in order to know on who added the school data. I have a users table already, which will establish the relation in the schools table.
My goal is when an admin is logged in, he/she can see all of the School records, otherwise if it's a user, then only fetch the records he/she added. The problem is that I can't figure out on when and where to insert the user_id data during the store request as I'm getting an error "user id field is required". Here's what I've tried so far:
Migration:
class CreateSchoolsTable extends Migration
{
public function up()
{
Schema::create('schools', function (Blueprint $table) {
$table->id();
$table->string('school_name');
$table->foreignId('user_id')->constrained()->cascadeOnDelete();
$table->timestamps();
});
}
}
School Model:
class School extends Model
{
use HasFactory;
protected $fillable = ['school_name', 'user_id'];
public function User() {
return $this->belongsTo(User::class);
}
}
Store Request:
class StoreSchoolRequest extends FormRequest
{
public function rules(): array
{
return [
'school_name' => 'required|string|max:255',
'user_id' => 'required|exists:users,id'
];
}
}
Controller:
class SchoolController extends Controller
{
public function store(StoreSchoolRequest $request) {
$school_data = $request->validated();
$user_id = \Auth::user()->id;
$school_data['user_id'] = $user_id;
School::create($school_data );
return Redirect::route('schools.index');
}
}
Any inputs will be of big help! Thanks.
Laravel has elegant way to bind authenticated user_id. Remove user_id from request class and chaining method. Also setup relationship from User model to School Model
Form Request Class
class StoreSchoolRequest extends FormRequest
{
public function rules(): array
{
return [
'school_name' => 'required|string|max:255',
];
}
}
User Model
protected $fillable = ['school_name', 'user_id'];
...
// new line
public function schools() {
return $this->hasMany(School::class);
}
Your Controller
class SchoolController extends Controller
{
public function store(StoreSchoolRequest $request) {
auth()->user()->schools()->create($request->validated());
return Redirect::route('schools.index');
}
}
UPDATE ANSWER
Since user_id value is school name (based on image link from comment), probably there's something wrong either in User or School model. Here the quick fix
Your Controller
class SchoolController extends Controller
{
public function store(StoreSchoolRequest $request) {
auth()->user()->schools()->create(
array_merge(
$request->validated(),
['user_id' => auth()->id()]
)
);
return Redirect::route('schools.index');
}
}
You can add 'created_by' and 'updated_by' fields to your table. so you can register in these fields when additions or updates are made.
Then you can see who has added or updated from these fields.
class School extends Model
{
use HasFactory;
protected $fillable = ['school_name', 'user_id', 'created_by', 'updated_by'];
public function User() {
return $this->belongsTo(User::class);
}
}
Your controller part is correct but since you get the logged in user, you wont be having user_id in the request. So you should remove the rules about user_id from your StoreSchoolRequest.
class StoreSchoolRequest extends FormRequest
{
public function rules(): array
{
return [
'school_name' => 'required|string|max:255'
];
}
}
Problem is here ..
$school_data = $request->validated();
Since you are using $request->validated()..
You have to safe()->merge user_id into it , here Docs : .
$validated = $request->safe()->merge(['user_id' => Auth::user()->id]);
Then put this $validated into create query , Thanks. –
I have the following models using Laravel 5.3:
Provider:
// Provider model
$primaryKey = 'id'
public function activities()
{
return $this->hasMany(Activity::class);
}
Activity:
// Activity model
$primaryKey = 'id'
public function provider()
{
return $this-belongsTo(Provider::class);
}
public function semesters()
{
return $this->hasMany(Semester::class);
}
public function semesterPurchases()
{
return $this->hasManyThrough(Purchase::class, Semester::class, 'activity_id', 'purchasable_id')
->where('purchasable_type', Semester::class);
}
Semester:
// Semester model
$primaryKey = 'id'
public function activity()
{
return $this->belongsTo(\App\Models\Activity::class, 'activity_id', 'id');
}
Purchase:
// Purchase model
$primaryKey = 'id'
public function purchasable()
{
return $this->morphTo();
}
In my case Semester::class is the purchasable_type. Is there a way to establish a relationship between Provider::class and Purchase::class? In order to make it possible to do something like this:
$providers = Provider::select('id', 'name', 'address')
->with('purchases')
->where('providers.id', 1)
->get();
I would prefer not to go through activities like so:
$providers = Provider::select('id', 'name', 'address')
->with('activities.purchases')
->where('providers.id', 1)
->get();
which I know I can do using hasManyThrough on the Activity::class
Laravel has no native support for a direct relationship.
I've created a package for cases like this: https://github.com/staudenmeir/eloquent-has-many-deep
class Provider extends Model
{
use \Staudenmeir\EloquentHasManyDeep\HasRelationships;
public function purchases()
{
return $this->hasManyDeep(
Purchase::class,
[Activity::class, Semester::class],
[null, null, ['purchasable_type', 'purchasable_id']]
);
}
}
Provider::find($id)->purchases;
I have 3 models
User - Role- Permission
User
class User extends Model
{
protected $fillable = [
'name', 'email', 'password',
];
public function roles()
{
return $this->belongsToMany(Role::class);
}
}
Role
class Role extends Model
{
protected $fillable = ['name' , 'label'];
public function users()
{
return $this->belongsToMany(User::class);
}
public function permissions()
{
return $this->belongsToMany(Permission::class);
}
}
Permission
class Permission extends Model
{
protected $fillable = ['name' , 'label'];
public function roles()
{
return $this->belongsToMany(Role::class);
}
}
I want get List of users whose permissions were updated on a specific date
I know I sould use something like below but I dont know exatly how to use Where
$users = User::with('roles.permissions')->orderBy('name', 'asc')->paginate(25);
thanks alot
Use whereHas():
$users = User::whereHas('roles.permissions', function($query) use($date) {
$query->whereDate('permission_role.updated_at', $date);
})->orderBy('name', 'asc')->paginate(25);
I have a problem with a many to many relationship and the translations of the terms.
I have 4 tables:
products
- id, price, whatever
products_lang
- id, product_id, lang, product_name
accessori
- id, active
accessori_lang
- id, accessori_id, lang, accessori_name
I'm trying to assign accessories to products with an intermediate table named:
accessori_products
this is the model for Product:
class Product extends Model {
protected $table = 'products';
public function productsLang () {
return $this->hasMany('App\ProductLng', 'products_id')->where('lang','=',App::getLocale());
}
public function productsLangAll() {
return $this->hasMany('App\ProductLng', 'products_id');
}
public function accessori() {
return $this->belongsToMany('App\Accessori', 'accessori_products');
}
}
this is the model for productLng:
class ProductLng extends Model {
protected $table = 'products_lng';
public function products() {
return $this->belongsTo('App\Product', 'products_id', 'id');
}
}
Then I have the model for Accessori:
class Accessori extends Model {
protected $table = 'accessori';
public function accessoriLang() {
return $this->hasMany('App\AccessoriLng')->where('lang','=',App::getLocale());
}
public function accessoriLangAll() {
return $this->hasMany('App\AccessoriLng');
}
public function accessoriProducts() {
return $this->belongsToMany('App\Products', 'accessori_products', 'accessori_id', 'products_id');
}
}
And the model for AccessoriLng:
class accessoriLng extends Model {
protected $table = 'accessori_lng';
public function accessori() {
return $this->belongsTo('App\Accessori', 'accessori_id', 'id');
}
}
the last model is for the relationship between the two tables above:
class ProductAccessori extends Model {
protected $table = 'accessori_products';
public function accessoriProducts() {
return $this->belongsTo('App\Product', 'accessori_id', 'products_id');
}
}
I'm trying to get the accessories of each product and to get also the translation but I'm having a lot of problem with this.
It's my first time with a many to many relation with translations too.
Can anyone put me on the right direction?
controller
$products = Product::has('accessori')->with([
'productsLang ',
'accessori' => function ($accessori){
$accessori->with([
'accessoriLang'
]);
}
])->get();
return $products;
you'll get products with accessori that has accessoriLang.

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
use Laravel\Scout\Searchable;
class Event extends Model
{
protected $table = 'events';
public $timestamps = true;
use Searchable;
use SoftDeletes;
protected $dates = ['deleted_at'];
public function entities()
{
return $this->belongsTo('App\Entity', 'entity_id');
}
public function users()
{
return $this->belongsTo('App\User', 'id');
}
public function events()
{
return $this->belongsTo('App\DirtyEvent', 'id');
}
public function toSearchableArray()
{
$data = $this->toArray();
$data['entities'] = $this->entities->toArray();
return $data;
}
}
This is my model for Event, as you can see I am using toSearchableArray which is Laravel scout function to import 'relations' to algolia. However the problem is that sometimes it is empty. So for example
event id 1 has entity_id 1
but in another example
event id 2 has entity_id = null
How can I modify this function to check if the entities() relation is not empty before putting it into array?
if i understand u correctly this should help. if the relationship does not exist return an empty array and scout won't update the index
public function toSearchableArray()
{
if(is_null($this->entities)){
return [];
}
$this->entities
return $this->toArray();
}
please update foreign_key in relation as this
user_id as foreign_key instead of id
event_id as foreign_key instead of id
public function users()
{
return $this->belongsTo('App\User', 'user_id');
}
public function events()
{
return $this->belongsTo('App\DirtyEvent', 'event_id');
}
I think if load the relation before the toArray().
public function toSearchableArray()
{
$this->entities;
return $this->toArray();
}
