Seeding a eloquent morphToMany relationship in laravel - laravel

Question

I'm currently working on a laravel application where a user can like/dislike a content.
The migrations for the respective tables look as follows, where user_content_interaction is the relation between users and contents:
<?php
declare(strict_types=1);
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateUserTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('user', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->string('email')->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('user');
}
}
<?php
declare(strict_types=1);
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateContentTable extends Migration
{
public const URL_LEN = 2083;
public const STR_LEN = 256;
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('content', function (Blueprint $table) {
$table->id();
$table->string('title', self::STR_LEN);
$table->date('release_date');
$table->enum('content_type', ['movie', 'tv_show', 'short_film', 'mini_tv_show']);
$table->json('genre');
$table->json('tags');
$table->integer('runtime');
$table->longText('short_description');
$table->json('cast');
$table->json('directors');
$table->enum('age_restriction', [0, 6, 12, 16, 18]);
$table->string('poster_url', self::URL_LEN);
$table->string('youtube_trailer_url', self::URL_LEN);
$table->string('production_company', self::STR_LEN);
$table->integer('seasons');
$table->integer('average_episode_count');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('content');
}
}
<?php
declare(strict_types=1);
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateUserContentInteractionTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('user_content_interaction', function (Blueprint $table) {
$table->foreignId('content_id')->constrained('content');
$table->foreignId('user_id')->constrained('user');
$table->primary([
'content_id',
'user_id'
]);
$table->enum('like_status', ['liked', 'disliked'])->nullable();
$table->integer('dislike_count')->default(0)->nullable(false);
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('user_content_interaction');
}
}
The respective models look like this:
<?php
declare(strict_types=1);
namespace App\Models;
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;
use HasFactory;
use Notifiable;
/**
* Name of the associated Table in the Database
*
* #var string
*/
protected $table = 'user';
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'name',
'email',
'password',
];
/**
* The attributes that should be hidden for arrays.
*
* #var array
*/
protected $hidden = [
'password',
'remember_token',
];
/**
* The attributes that should be cast to native types.
*
* #var array
*/
protected $casts = [
'email_verified_at' => 'datetime',
];
public function contents(): \Illuminate\Database\Eloquent\Relations\HasMany
{
return $this->hasMany(Content::class);
}
}
<?php
declare(strict_types=1);
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Content extends Model
{
use HasFactory;
/**
* Name of the associated Table in the Database
*
* #var string
*/
protected $table = 'content';
/**
*
* The primary key of the table
*
* #var string
*/
protected $primaryKey = 'id';
/**
*
* The columns that are fillable
*
* #var array
*/
protected $fillable = [
'title',
'release_date',
'content_type',
'genre',
'tags',
'runtime',
'short_description',
'cast',
'directors',
'age_restriction',
'poster_url',
'youtube_trailer_url',
'production_company',
'seasons',
'average_episode_count',
'updated_at'
];
protected $casts = [
'varchar' => 'string',
'release_date' => 'string',
'content_type' => 'string',
'genre' => 'string',
'tags' => 'string',
'runtime' => 'int',
'short_description' => 'string',
'cast' => 'string',
'directors' => 'string',
'age_restriction' => 'string',
'seasons' => 'int',
'average_episode_count' => 'int',
];
}
<?php
declare(strict_types=1);
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Relations\BelongsTo;
use Illuminate\Database\Eloquent\Relations\Pivot;
class UserContentInteraction extends Pivot
{
use HasFactory;
/**
* Name of the associated Table in the Database
*
* #var string
*/
protected $table = 'user_content_interaction';
protected $primaryKey = 'content_id';
protected $foreignKey = 'user_id';
public function user(): BelongsTo
{
return $this->belongsTo('User');
}
public function content(): BelongsTo
{
return $this->belongsTo('Content');
}
}
And I'm trying to seed the database on my dev env like this:
User::factory()->count(4)
->hasAttached(
Content::factory()->count(10),
[
'like_status' => Arr::random(['liked', 'disliked']),
'created_at' => Carbon::now()
],
)
->create();
Which results in the following error when calling the create() method of the user factory:
Call to undefined method Illuminate\Database\Eloquent\Relations\HasMany::attach()
I'm looking for any advice how to fix this problem, maybe I made a design mistake in the first place. Or there is an easier way to construct this relation. Though it would be cool if I could keep the custom name for the relation. I'm very unfamiliar with Eloquent ORM so when there is a much easier and lightweight way of doing this feel free to point that out.
EDIT:
I adjusted the relationship migration to look like this:
<?php
declare(strict_types=1);
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateUserContentInteractionTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('user_content_interactions', function (Blueprint $table) {
$table->id('user_content_interaction_id');
$table->foreignId('content_id')->constrained('content');
$table->foreignId('user_id')->constrained('user');
$table->enum('like_status', ['liked', 'disliked'])->nullable();
$table->integer('dislike_count')->default(0)->nullable(false);
$table->string('user_content_interaction_type');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('user_content_interaction');
}
}
fixed some errors and defined the relation in the model like this:
public function contents(): \Illuminate\Database\Eloquent\Relations\MorphToMany
{
return $this->morphToMany(Content::class, 'user_content_interaction');
}
Now I'm facing the problem that when seeding the ids from User and Content aren't taken into the relationship as foreign ids. The error message looks like this:
SQLSTATE[HY000]: General error: 1364 Field 'user_id' doesn't have a default value (SQL: insert into `user_content_interactions` (`content_id`, `created_at`, `like_status`, `user_content_interaction_id`, `user_content_interaction_type`) values (1, 2022-10-26 16:51:14, disliked, 1, App\Models\User))
I think I have some mistake in the seeder. I feel like I have to do something like this in the seeder:
User::factory()->count(4)
->hasAttached(
Content::factory()->count(10),
[
'user_id' => currentUser->id,
'content_id' => currentContent->id,
'like_status' => Arr::random(['liked', 'disliked']),
'created_at' => Carbon::now()
],
)
->create();
