Laravel Many to many store to database - php

Question

I want a system where I connect users with tasks and later I can assign tasks to different users from the amdin panel. My program doesn't work, it doesn't assign tasks to users. Later, I want to make sure that when a user logs in, they can only see their own tasks that an amdin has given them. Please help me what is the problem?!
Create user_task
Schema::create('user_task', function (Blueprint $table) {
$table->id();
$table->foreignId('task_id')->constrained()->onDelete('cascade');
$table->foreignId('user_id')->constrained()->onDelete('cascade');
$table->timestamps();
});
Create users
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('email')->unique();
$table->string('avatar')->default('default.jpg');
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
Create tasks
Schema::create('tasks', function (Blueprint $table) {
$table->id();
$table->string('alkalmazott');
$table->string('projekt')->default('-');
$table->string('feladat');
$table->date('hatarido');
$table->timestamps();
});
Task model
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Task extends Model
{
use HasFactory;
protected $fillable = [
'alkalmazott', 'projekt' , 'feladat', 'hatarido'
];
public function projects(){
return $this->belongsToMany('App\Models\Project');
}
public function users()
{
return $this->belongsToMany('User', 'user_tasks');
}
}
User model
<?php
namespace App\Models;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Illuminate\Support\Facades\Hash;
use Laravel\Sanctum\HasApiTokens;
use Tasks;
class User extends Authenticatable
{
use HasApiTokens, HasFactory, Notifiable;
/**
* The attributes that are mass assignable.
*
* #var string[]
*/
protected $fillable = [
'name',
'email',
'password',
];
/**
* The attributes that should be hidden for serialization.
*
* #var array
*/
protected $hidden = [
'password',
'remember_token',
];
/**
* The attributes that should be cast.
*
* #var array
*/
protected $casts = [
'email_verified_at' => 'datetime',
];
//public function setPasswordAttribute($password) {
// $this->attributes['password'] = Hash::make($password);
//}
public function jogoks(){
return $this->belongsToMany('App\Models\Jogok');
}
public function tasks()
{
return $this->belongsToMany('Task', 'user_tasks');
}
/* Check if the user has a role
* #param string $role
* #return bool
*/
public function hasAnyRole(string $role){
return null !== $this->jogoks()->where('name', $role)->first();
}
/* Check if the user has any given role
* #param array $role
* #return bool
*/
public function hasAnyRoles(array $role){
return null !== $this->jogoks()->whereIn('name', $role)->first();
}
}
Task controller (here i want to upload tasks)
<?php
namespace App\Http\Controllers;
use App\Models\Project;
use App\Models\Task;
use App\Models\User;
use Illuminate\Http\Request;
class TasksController extends Controller
{
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function index()
{
$tasks = Task::latest()->paginate(10);
return view('admin.tasks.index',compact('tasks'))
->with('i', (request()->input('page', 1) - 1) * 5);
}
/**
* Show the form for creating a new resource.
*
* #return \Illuminate\Http\Response
*/
public function create()
{
return view('admin.tasks.create', ['users' => User::all()], ['tasks' => Task::all()]);
}
/**
* Store a newly created resource in storage.
*
* #param \Illuminate\Http\Request $request
* #return \Illuminate\Http\Response
*/
public function store(Request $request)
{
$request->validate([
'alkalmazott' => 'required',
'projekt' => 'required',
'feladat' => 'required',
'hatarido' => 'required',
]);
Task::create($request->all());
return redirect()->route('admin.tasks.index')
->with('success','Product created successfully.');
}
/**
* Display the specified resource.
*
* #param \App\Models\Task $Task
* #return \Illuminate\Http\Response
*/
public function show(Task $Task)
{
return view('admin.tasks.show',compact('Task'));
}
/**
* Show the form for editing the specified resource.
*
* #param \App\Models\Task $Task
* #return \Illuminate\Http\Response
*/
public function edit(Task $Task)
{
return view('admin.tasks.edit',compact('Task'));
}
/**
* Update the specified resource in storage.
*
* #param \Illuminate\Http\Request $request
* #param \App\Models\Task $Task
* #return \Illuminate\Http\Response
*/
public function update(Request $request, Task $Task)
{
$request->validate([
'alkalmazott' => 'required',
'projekt' => 'required',
'feladat' => 'required',
'hatarido' => 'required',
]);
$Task->update($request->all());
return redirect()->route('admin.tasks.index')
->with('success','Product updated successfully');
}
/**
* Remove the specified resource from storage.
*
* #param \App\Models\Task $Task
* #return \Illuminate\Http\Response
*/
public function destroy(Task $Task)
{
$Task->delete();
return redirect()->route('admin.tasks.index')
->with('success','Product deleted successfully');
}
}
And after i run my upload form, on the phpmyadmin the task has uploaded done but in the user_task table not working. Because its not working i cant display tasks for the users. Thank you for your replies!

Answer 1

You can use attach(), detach() or sync() functions in controller.
For example:
public function store(Request $request){
// ...
$task = Task::create($request->all());
$task->users->attach($request->users); // or you can use sync(), according to your needs and project
// $request->users must be an array like [1,3,10,21,28] etc.
// ...
}
