显示具有父类别和子类别Laravel的产品

Question

我的模型类别具有父子关系：

Object.keys(properties).forEach(function(key) {
  // console.log("dealing with key ",key,properties[key])

  if (uischema[key] == undefined) {
    uischema[key] = {}
  }
  if (properties[key].type == "object") {


    console.log(key + " is a lvl2 Object!")
    Object.keys(properties[key].properties).forEach(function(key2) {
      if (uischema[key][key2] == undefined) {
        uischema[key][key2] = {}
      }
      if (properties[key].properties[key2].type == "object") {

        // console.log(key2 + " is a lvl3 Object!",properties[key].properties[key2].properties,uischema[key])
        Object.keys(properties[key].properties[key2].properties).forEach(function(key3) {
          if (uischema[key][key2][key3] == undefined) {
            uischema[key][key2][key3] = {}
          }
          if (properties[key].properties[key2].properties[key3].type == "object") {

我有具有关联类别的产品模型：

public function children()
{
    return $this->hasMany(self::class, 'parent_id');
}

public function parent()
{
    return $this->belongsTo(self::class, 'parent_id')->withoutGlobalScope('active');
}

public function products()
{
    return $this->hasMany(Product::class);
}

在CategoryController中，我有方法show：

public function category()
{
    return $this->belongsTo(Category::class);
}

在刀片中，我将产品展示为：

public function show(Category $category)
{
    return view('main', compact('category'));
}

如果isset @php $products = isset($category) ? $category->products()->paginate(15) : $products; @endphp @include('partials.products') 变量，那么我得到产品。但这仅适用于某些类别。如何在此格式表中显示父级和子级标题和产品：

category

现在我有了这个

<table>
    <tr>
         <th>Name Product</th>
         <th> Price </th>
    </td>
    <tr>
           <td colspan=2>Parent Category title of products</td>
    </tr>
    <tr>
            <td>Product of parent category #1</td>
            <td>890 $ </td>
    </tr>
    <tr> 
           <td colspan=2>Child category title of products</td>
    </tr>
    <tr>
            <td>Product of child category #1</td>
            <td>890 $ </td>
    </tr>
    ...
</table>

在<table class="table"> <tr> <th class="th-1">Name</h2></th> <th class="th-2">Count <!--<span><i class="fas fa-chevron-up"></i>--></span></th> <th class="th-3">Price <!--<span><i class="fas fa-chevron-up"></i>--></span></th> <th class="th-4">Sales <!--<span><i class="fas fa-chevron-up"></i>--></span></th> <th class="th-5"></th> </tr> {{-- {{ dd($products->groupBy('category_id')) }} --}} @php $products = isset($category) ? $category->products()->paginate(15) : $products; @endphp @include('partials.products') </table> 中：

partials.products

请帮助解决此问题。
