in laravel 8 model factory gives array error - php

Question

i'am laravel beginner and want to create a model factory. RegulationFactory
i use factories and database seeder for make them.
and when i want to seed it , gives error :
ErrorException : Array to string conversion
can you help me for fix it?
this is my regulation migration :
public function up()
{
Schema::create('regulations', function (Blueprint $table) {
$table->id();
$table->unsignedBigInteger('user_id');
$table->string('country');
$table->string('photo');
$table->string('short_description');
$table->longText('description');
$table->string('population');
$table->string('area');
$table->string('internet_penetration');
$table->string('national_currency');
$table->string('goverment');
$table->string('president');
$table->string('capital');
$table->string('language');
$table->float('economic_growth');
$table->string('dgtl_curr_lgs')
->comment('Legislation of digital currencies');
$table->string('dgtl_curr_tax')
->comment('Tax on digital currencies');
$table->string('dgtl_curr_pymt')
->comment('Payment status through digital currency');
$table->string('dgtl_curr_ntiol')
->comment('National Digital Currency');
$table->string('ICO');
$table->string('crpto_antimon_rules')
->comment('has Anti-money laundering rules for crypto or not');
$table->tinyInteger('status')
->comment('status is 1 when a regulation is active and it is 0 otherwise.')->nullable();
$table->foreign('user_id')->references('id')->on('users');
$table->rememberToken();
$table->softDeletes();
$table->timestamps();
});
}
this is my regulation factory :
public function definition()
{
$users = User::pluck('id');
return [
'user_id'=>\App\Models\User::inRandomOrder()->first()->id,
'country'=>$this->faker->country,
'photo'=>$this->faker->text(10),
'description'=>$this->faker->sentences(50),
'short_description'=>$this->faker->sentence(50),
'population'=>$this->faker->numerify('########'),
'area'=>$this->faker->numerify('########'),
'internet_penetration'=>$this->faker->numerify('#########'),
'national_currency'=>$this->faker->word,
'goverment'=>$this->faker->words,
'president'=>$this->faker->name,
'capital'=>$this->faker->city,
'language'=>$this->faker->words,
'economic_growth'=>$this->faker->numerify('#'),
'dgtl_curr_lgs'=>$this->faker->sentence(1),
'dgtl_curr_tax'=>$this->faker->words,
'dgtl_curr_pymt'=>$this->faker->words,
'dgtl_curr_ntiol'=>$this->faker->words,
'ICO'=>$this->faker->word,
'crpto_antimon_rules'=>$this->faker->word,
];
}
and my regulation model :
class Regulation extends Model
{
use HasFactory;
protected $fillable = [
'user_id' ,
'country' ,
'photo',
'short_description' ,
'description',
'area',
'internet_penetration',
'national_currency',
'goverment',
'president',
'capital',
'language',
'economic_growth',
'dgtl_curr_lgs',
'dgtl_curr_tax',
'dgtl_curr_pymt',
'dgtl_curr_ntiol',
'ICO',
'crpto_antimon_rules',
];
public function users(){
return $this->belongsTo(User::class);
}
}
where is my mistake? thank you for your help :}

Answer 1

Your mistake is you are using $this->faker->words. Should be $this->faker->word (without "s")
see: Faker Provider Lorem

Answer 2

As you have used $this->faker->words. Here, $this->faker->words(5) expects a number of words. So, you need to set the number of words by passing value or you can use only "$this->faker->word"
