小编AiA*_*him的帖子

嗨，我试图让 Array 包含所有类别以及每个类别中的帖子数：例如：

[
{id: 1, name: "category1", posts: 15 },
{id: 2, name: "category2", posts: 33 },
{id: 3, name: "category3", posts: 27 }
]

细节：

• 帖子表

[
{id: 1, name: "category1", posts: 15 },
{id: 2, name: "category2", posts: 33 },
{id: 3, name: "category3", posts: 27 }
]

• 类别表

public function up()
{
    Schema::create('posts', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->bigInteger('user_id')->unsigned();
        $table->foreign('user_id')->references('id')->on('users');
        $table->string('slug')->unique();
        $table->string('title');
        $table->string('image');
        $table->text('description');
        $table->integer('category_id')->unsigned();;
        $table->longText('content');
        $table->boolean('published')->default(0);
        $table->timestamps();
    });
}

• 帖子模型

{
