Laravel 获取并分页相同的数据

Question

我使用 Laravel 作为控制器，使用 blade 文件作为网页。我的代码是这样的：

PropertiesController

$properties = Property::where('status', 1);
$properties = $properties->orderBy('properties.created_at', 'DESC')->paginate(8);
return view('properties.index')->with('properties', $properties);

在index.blade.php

@foreach ($properties as $property)
<div class="geo">
  <span class="lat">{{ $property->title }}</span>,
  <span class="lng">{{ $property->description }}</span>
</div>

我想实现的是获取类别w.r.t。与属性一起计数，为此，我正在做

$properties = Property::where('status', 1);

$categories = array();
if (is_null($req->c)) {
    $search = $properties;
    foreach (Category::all() as $category) {
     array_push(
       $categories,
          array(
            'id' => $category->id,
            'name' => $category->category,
            'counts' => count($search->where('properties.category', $category->id)->get()),
          )
       );
    }
}

$properties = $properties->orderBy('properties.created_at', 'DESC')->paginate(8);

return view('properties.index')->with('properties', $properties)->with('categories', $categories);

$search = $properties; 和
'counts' => count($search->where('properties.category', $category->id)->get()),

有了这个它给了我

正在尝试获取属性个 non-object
<span class="lat"><?php echo e($property->title); ?></span>,

Answer 1

如果关系是在模型中建立的，你应该只以这种方式使用 with ()。控制器应该是这样的。

$properties = Property::where('status', 1)->with('category')->orderBy('properties.created_at', 'DESC')->paginate(8);
return view('properties.index', compact('propierties'));

这将为您提供指定类别旁边的属性列表。

但是如果您需要列出类别并在每个类别中具有属性，则必须这样做。

$categories = Category::with('properties')->paginate(8);
return view('properties.index', compact('categories'));

Answer 2

我认为您想将数据传递给 blade 查看并获取每个类别的分类数据计数...为此，您可以使用重复函数分别对数据进行计数。例如：

public function properties() {
    $properties = Property::where('status', 1);

    $categories = array();
    foreach (Category::all() as $category) {
        $count = $this->count($category->id);
        array_push(
            $categories,
            array(
                'id' => $category->id,
                'name' => $category->category,
                'counts' => $count,
            )
        );
    }

    $properties = $properties->orderBy('properties.created_at', 'DESC')->paginate(8);

    return view('properties.index')->with('properties', $properties)->with('categories', $categories);
}


public function count($id) {
    $count = count(Property::where('category_id', $id)); // or any variable you are using to connect categories table with
    return $count;
}

$count = $this->count($category->id);

这是成功的行。
