我是否需要为每个重复输入创建一个新 ID？

Question

为了解释，我正在为用户创建一种创建膳食计划的方法。像这样;

，简单说明一下。它将被设计为用户可以通过交互式单击 3x3 table 中的日期来填写当天的膳食，这将更改天数以使用 j 查询在下面输入膳食。

添加早餐、小吃、午餐、小吃、晚餐和小吃时，我的困惑就来了。由于一周中的每一天都需要它，我是否需要像这样为每一天创建一个不同的 ID；

    class CreateMealPlansTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('meal_plans', function (Blueprint $table) {
            $table->id();
            $table->unsignedBigInteger('user_id');
            $table->unsignedBigInteger('recipes_id');
            $table->mediumText('monday'); //medium height text
            $table->mediumText('breakfast1'); //medium height text
            $table->mediumText('snack1'); //medium height text
            $table->mediumText('lunch1'); //medium height text
            $table->mediumText('snack1a'); //medium height text
            $table->mediumText('dinner1'); //medium height text
            $table->mediumText('snack1b'); //medium height text
            $table->mediumText('tuesday'); //medium height text
            $table->mediumText('breakfast2'); //medium height text
            $table->mediumText('snack2'); //medium height text
            $table->mediumText('lunch2'); //medium height text
            $table->mediumText('snack2a'); //medium height text
            $table->mediumText('dinner2'); //medium height text
            $table->mediumText('snack2b'); //medium height text


            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('meal_plans');
    }
}

我觉得这是一个冗长的方法，因为我会有 6 个不同的早餐 ID。有没有办法写得更短更简洁？

发布同一输入的多个实例时，它保存在数据库中的什么位置？

当使用 json 然后将 id 添加到我的视图中时，它应该是这样的吗？（这仅适用于周一和周二）

Answer 1

如果您需要将这些数据集中在一个 table 中。那么最好使用较新数据库版本中可用的 JSON 数据结构来存储您的膳食数据。例如：

Schema::create('meal_plans', function (Blueprint $table) {
    $table->id();
    $table->unsignedBigInteger('user_id');
    $table->unsignedBigInteger('recipes_id');
    $table->unsignedBigInteger('day_id');
    $table->json('meals');
    $table->timestamps();
});

注意：如果您不打算使用单独的主 table 来节省时间，请跳过 day_id 外键并将其用作字符串。理想情况下将其保留为 id 将有助于您轻松查询。

如果您不需要复杂的查询（例如获取所有用户的午餐详细信息或他们的早餐详细信息等），这将有效。如果您需要这样的东西，最好将数据拆分为第二个 table 以进行维护关注点分离和数据库设计原则。
