Laravel 使用seed时出现错误异常

我有一个数据库包含一些表…其中一个（thsises表）。。我试图散布一些虚假数据。。但是当我跑的时候 php artisan数据库：种子 它抛出一个SQL错误。。。这是我在这张桌子上的工厂：

$factory->define(App\Thesise::class, function (Faker\Generator $faker) {

return [
    'program_id' =>$faker->numberBetween($min = 1, $max = 5),
    'ar_title' =>$faker->sentences,
    'en_title' =>$faker->sentences,
    'student_id' =>$faker->numberBetween($min = 3, $max = 20),
    'ar_brief' =>$faker->sentences,
    'en_brief' =>$faker->sentences,
    'ar_expalin' =>$faker->text,
    'en_explain' =>$faker->text,
    'date' =>$faker->date($format = '2000-01-01', $max = 'now'),
    'primary_siminar' =>$faker->date($format = '2000-01-01', $max = 'now'),
    'final_siminar' =>$faker->date($format = '2000-01-01', $max = 'now'),
    'test_date' =>$faker->date($format = '2000-01-01', $max = 'now'),
    'degree_date' =>$faker->date($format = '2000-01-01', $max = 'now'),
    'degree' =>$faker->randomFloat($nbMaxDecimals = 2, $min = 60, $max = 100), // 48.8932
    'degreey' =>$faker->sentences,
    'mat_avg' =>$faker->randomFloat($nbMaxDecimals = 2, $min = 60, $max = 100), // 48.8932
    'final_degree' =>$faker->randomFloat($nbMaxDecimals = 2, $min = 60, $max = 100), // 48.8932
    'f_ad' =>$faker->numberBetween($min = 1, $max = 10),
    'f_a' =>$faker->numberBetween($min = 1, $max = 10),
    'j_ad' =>$faker->numberBetween($min = 1, $max = 10),
    'j1' =>$faker->numberBetween($min = 1, $max = 10),
    'j2' =>$faker->numberBetween($min = 1, $max = 10),
    'file' =>$faker->sentences,
];

}))

这是迁移表的up函数

   public function up()
{
    Schema::create('thesises', function(Blueprint $table) {
        $table->increments('id');
        $table->integer('program_id');
        $table->string('ar_title');
        $table->string('en_title');
        $table->integer('student_id')->unsigned();
        $table->text('ar_brief');
        $table->text('en_brief');
        $table->longText('ar_expalin');
        $table->longText('en_explain');
        $table->date('date');
        $table->date('primary_siminar');
        $table->date('final_siminar');
        $table->date('test_date');
        $table->date('degree_date');
        $table->double('degree');
        $table->string('degreey');
        $table->double('mat_avg');
        $table->double('final_degree');
        $table->integer('f_ad');
        $table->integer('f_a');
        $table->integer('j_ad');
        $table->integer('j1');
        $table->integer('j2');
        $table->string('file');
        $table->timestamps();
    });
}

该种子是这样的：

class ThesisesTableSeeder extends Seeder
{
/**
 * Run the database seeds.
 *
 * @return void
 */
public function run()
{
    factory(\App\Thesise::class , 10)->create();
}

}

我称之为：

class DatabaseSeeder extends Seeder
{
/**
 * Run the database seeds.
 *
 * @return void
 */
public function run()
{
     $this->call(ThesisesTableSeeder::class);
}

}

当我播种。。它抛出错误异常（数组到字符串转换）…请提供帮助

根据

Faker\Generator

类，方法/属性

语句

返回字符串数组

• @属性字符串$语句
• @方法字符串语句（$nbWords=6，$variableNbWords=true）
• @属性字符串|数组$句子
• @方法字符串|数组语句（$nb=3，$asText=false）

因此，您应该使用方法/属性

语句

。例如：

$factory->define(App\Thesise::class, function (Faker\Generator $faker) {
    return [
        ...
        'ar_title' => $faker->sentence, // or.
        'en_title' => $faker->sentence(3, true),
        ...
    ];
}

告诉我你在哪里以及如何调用你的工厂。我从DatabaseSederPublic函数run（）{$this->call（TheseStableSeeder:：class）；}调用它，而TheseStableSeeder是。。。。。公共函数run（）{factory（\App\Thesise:：class，10）->create（）；}你能在你的问题中添加这行代码吗？告诉我你在哪里以及如何调用你的工厂。我从DatabaseSederPublic函数run（）{$this->call（thesistableseeder:：class）；}中调用它，而sestableeder是。。。。。公共函数run（）{factory（\App\thesis:：class，10）->create（）；}}您能在问题中添加这行代码吗？
