I am trying to show best products based on collections . So in collections I have created a product meta field which stores the list of products . When I am retrieving the list in product page then its not showing the data .

{% assign first_collection = product.collections | first %}

{% assign collection_handle = first_collection.handle %}
<p>Collection Name: {{ collections[collection_handle].title }}</p>

<div class="related-products-wrapper">
{% assign related_products = collections[collection_handle].metafields.custom.test %}
  {{ collections[collection_handle].metafields.custom.test  }}
{% if related_products %}
    <h3>You might also like:</h3>
    <div class="related-product-list">
        {% for related_product in related_products %}
            <a href="{{ shop.url | append: '/products/' | append: related_product.handle }}">
                <div class="related-product">
                    <div class="related-product-image">
                        <img src="{{ related_product.featured_image | img_url: 'medium' }}" />
                    </div>
                    <div class="related-product-name">{{ related_product.title }}</div>
                    <div class="related-product-price">{{ related_product.price | money }}</div>
                </div>
            </a>
        {% endfor %}
    </div>
{% endif %}

Here ” collection_handle” is fetching the handle of collection which is attached to the product , so want to show the products which are attached to that particular collection .
