Why am i getting this error when i try to add foreign keys on Invoice table?

November 20, 2021

I have to tables: users and invoices
this is the up function for the users migration:

    {
        Schema::create('users', function (Blueprint $table) {
            $table->id();
            $table->string('name')->unique();
            $table->string('email')->unique();
            $table->string('phone')->unique();
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->string('comentarii');

            $table->rememberToken();
            $table->timestamps();
        });
    }

and this is the up function for the invoices

 public function up()
    {
        Schema::create('invoices', function (Blueprint $table) {
            $table->id();
            $table->unsignedInteger('user_id');
            $table->foreign('user_id')->refferences('id')->on('users');
            $table->integer('InvoiceNumber');
            $table->dateTime('date');
            $table->string('serviceInvoiced');
            
            $table->timestamps();
        });
    }

All i am trying to do is to make a one to many relationship as in a user can have multiple invoices

here is the User model:


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 Laravel\Sanctum\HasApiTokens;

class User extends Authenticatable
{
    use HasApiTokens, HasFactory, Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var string[]
     */
    protected $guarded = [];

    /**
     * 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 getInvoices()
    {
        return $this->hasMany(Invoice::class);
    }
}

and here is the Invoice model:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Invoice extends Model
{
    use HasFactory;

    protected $guarded=[];

    public function getUsers()
    {
        return $this->belongsTo(User::class);
    }
}
