如何在Laravel 5中排序和搜索集合实例

Question

我在一个物业的两个模型之间有一个多对多的枢纽关系，还有一个日期，用户可以看到该日期是否可供预订。一切正常，直到我想搜索可用的日期。我的用户提交了两个日期，我想对与该会议室相关的所有日期进行排序，并显示这两个用户输入之间的日期。我知道并尝试过dateBetween，但是因为我使用的是数据透视表，所以我必须以某种方式在排序和搜索集合实例上执行此操作。这是我的收藏，我想看看是否可以对它进行排序和操作。

Collection {#1606 ▼
 #items: array:1 [▼
    0 => Property {#1441 ▼
      #connection: "mysql"
      #table: "properties"
      #primaryKey: "id"
      #keyType: "int"
      +incrementing: true

控制器

if (!empty($request->start_date)) 
{
    $pdate = Property::with('dates')->get();
    // Here on pdate i wana do some sorting and searching base on user send start and end date
    dd($pdate);
}

日期表

Schema::create('dates', function (Blueprint $table) {
    $table->bigIncrements('id');
    $table->dateTime('date');
    $table->float('price');
    $table->timestamps();
});

属性表

public function up()
{
    Schema::create('properties', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->integer('type');
        $table->text('title');
        $table->longText('description');
        $table->longText('image');
        $table->float('base_price');
        $table->dateTime('available_start');
        $table->dateTime('available_end');
        $table->integer('base_availability');
        $table->integer('base_capacity');
        $table->integer('max_occupancy');
        $table->float('extra_price');
        $table->timestamps();
    });
}

数据透视表

Schema::create('date_property', function (Blueprint $table) {
    $table->bigIncrements('id');
    $table->integer('property_id');
    $table->foreign('property_id')->references('id')->on('property');
    $table->integer('date_id');
    $table->foreign('date_id')->references('id')->on('date');
    $table->integer('reserved');
    $table->timestamps();
});
