运行 laravel 播种器时数组到字符串的转换错误

Question

我在运行播种器时遇到 ErrorException Array to string conversion 错误。

php artisan db:seed --class=StudentSeeder

我在StudentFactory.php上修改之前工作正常，我只是改变了所有的伪造者，我不知道是哪个在制造麻烦。

<?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(),
        ];
    }
}

Answer 1

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

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