运行 Laravel 播种机时数组到​​字符串的转换错误

问题描述

运行播种机时出现 ErrorException Array to string conversion 错误。

PHP artisan db:seed --class=StudentSeeder

在我对 StudentFactory.PHP 进行更改之前它工作正常，我只是更改了所有伪造者，我不知道是哪一个造成了这个麻烦。

<?PHP

namespace Database\Factories;

use Illuminate\Database\Eloquent\Factories\Factory;
use Illuminate\Support\Str;
use App\Models\Student;

class StudentFactory extends Factory
{
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = Student::class;

    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function deFinition()
    {
        return [
            'student_name' => $this->faker->name('male'),'cpr' => $this->faker->creditCardNumber,'email' => $this->faker->safeEmail,'mobile' => $this->faker->e164PhoneNumber,'mobile2' => $this->faker->e164PhoneNumber,'dob' => $this->faker->date(),'address' => $this->faker->address,'live_inـstate' => $this->faker->randomElement(["UNKNowN","OWN","RENT"]),'relationshipـstate' => $this->faker->randomElement(["UNKNowN","SINGLE","MARRIED","DIVORCED"]),'family_members' => $this->faker->randomNumber(),'family_depends' => $this->faker->randomNumber(),'degree' => $this->faker->text,'hawzaـhistory' => $this->faker->boolean,'hawzaـhistory_details' => $this->faker->paragraphs,'healthـhistory' => $this->faker->boolean,'healthـhistory_details' => $this->faker->paragraphs,'financialـstate' => $this->faker->randomElement(["UNKNowN","POOR","AVERAGE","GOOD","EXCELLENT"]),'financial_details' => $this->faker->paragraphs,'student_notes' => $this->faker->paragraphs,'registration_at' => $this->faker->date(),];
    }
}

解决方法

将所有出现的 $this->faker->paragraphs 更改为 $this->faker->paragraphs(3,true)。

paragraphs 格式化程序 。第二个参数 true 表示应该返回一个字符串而不是一个数组。
