I have two tables users and invoices. This is the up function for the users migration:

public function up()
{
    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();
    });
}

This is the up function for the invoices migration:

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);
    }
}

Here is the Invoice model:

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);
    }
}

What am I doing wrong? I watched multiple tutorials already. Here are the errors that im getting:

CodePudding user response：

The columns need to be of the same type. id() is an alias of bigIncrements(), so

$table->unsignedInteger('user_id');

should be

$table->unsignedBigInteger('user_id'); 

Also note: it's ->references('id'), not ->refferences('id')

More on Available Column Types

CodePudding user response：

you have tow issues:

1- you have a typo in your migration statement

2- $this->id() make unsignedBigInteger so user_id should be unsignedBigInteger

alter you migration lines to this:

 $table->unsignedBigInteger('user_id');
 $table->foreign('user_id')->references('id')->on('users'); //references not refferences
