Question

我知道这是一些转储错误，但是我暂时无法找到它。我有多对多的表餐和表成分。要输入一些假数据并创建Ingredient_meal表。我在下面发布了一些代码，但是当我使用db：seed --class = MealSeeder时，出现此错误

SQLSTATE [HY000]：常规错误：1364字段'title'没有默认值（SQL：插入meals （updated_at，created_at）值（2020-05-29 16:26:55，2020-05-29 16:26:55））

猜测该工厂无法正常工作，但无法在任何地方找到解决方案，我可以通过将nullable（）放入迁移和更新数据来解决此问题，但这似乎不对劲。预先感谢您的帮助！

MealFactory.php

    $factory->define(App\Meal::class, function (Faker $faker) {
    return [
        'title' => $faker->realText($maxNbChars = 10),
        'description' => $faker->realText($maxNbChars = 20),
    ];
});

   $factory->define(App\Ingredient::class, function (Faker $faker) {
        static $id = 1;
        return [
            'title' => $faker->realText($faker->numberBetween(10,15)),
            'slug' => $id++, //$faker->unique()->numberBetween(1,20),
        ];
    });

Meal.php模型

 protected $fillable = ['title','description'];

    public function ingredients()
    {
        return $this->belongsToMany('App\Ingredient');
    }

Model Ingredient.php

protected $fillable = ['title'];

public function meals()
{
    return $this->belongsToMany('App\Meal');
}

膳食迁移

Schema::create('meals', function (Blueprint $table) {
            $table->increments('id');
            $table->string('title');
            $table->text('description');
            $table->string('status')->default('created');
            $table->string('category')->nullable();
            $table->timestamps();

            //$table->foreign('category_id')->references('id')->on('categories')->onDelete('cascade');
        });

MealSeeder.php

factory(App\Meal::class, 10)->create()->each(function ($meals) {
    $meals->ingredients()->save(factory(App\Ingredient::class)->make());
});


factory(App\Ingredient::class, 10)->create()->each(function ($ingredients) {
    $ingredients->meals()->save(factory(App\Meal::class)->make());
});

// Get all the ingredients attaching up to 3 random ingredient to each meal
$ingredients = App\Ingredient::all();

// Populate the pivot table
App\Meal::all()->each(function ($meal) use ($ingredients) { 
    $meal->ingredients()->attach(
        $ingredients->random(rand(1, 3))->pluck('id')->toArray()
    ); 
});

编辑：我继续前进，没有找到正确的解决方案。我在迁移中设置了nullable（）属性，以表示'title'和'description'属性。运行seeder，然后填写所有空的数据，放入DB :: update。现在看起来很丑：（
