Hey there! Let's walk through how to populate the recommended products field for individual items in your Django Oscar 1.6.1 admin, plus set up sorting for them.

Step 1: Ensure Recommended Products Are Visible in the Admin #

First, check if your product edit page already has a section for related/recommended products. If not, you'll need to add an inline to the Product admin. Here's how:

1. In your project's admin.py (likely in a catalogue app override), import the necessary models and Oscar's default Product admin:

from django.contrib import admin
from oscar.core.loading import get_model
from oscar.apps.catalogue.admin import ProductAdmin as OscarProductAdmin

Product = get_model('catalogue', 'Product')
RelatedProduct = get_model('catalogue', 'RelatedProduct')

2. Define an inline class for RelatedProduct:

class RelatedProductInline(admin.TabularInline):
    model = RelatedProduct
    fk_name = 'product'  # Links to the parent product being edited
    extra = 1  # Shows one empty row to add new recommended products
    raw_id_fields = ('recommended',)  # Uses an ID picker instead of a huge dropdown (better for large catalogs)

3. Override the default ProductAdmin to include this inline:

class CustomProductAdmin(OscarProductAdmin):
    # Add our inline to the existing set of inlines from Oscar
    inlines = OscarProductAdmin.inlines + [RelatedProductInline]

# Unregister Oscar's default ProductAdmin and register our custom one
admin.site.unregister(Product)
admin.site.register(Product, CustomProductAdmin)

Restart your server, and when you edit a product in the admin, you'll now see a "Related Products" section at the bottom of the page.

Step 2: Add Recommended Products & Set Sort Order #

Now that the admin section is set up:

• Open the product you want to add recommendations for in the admin.
• Scroll to the "Related Products" inline section.
• Click "Add another Related Product".
• Use the "Recommended" field to select the product you want to recommend (the raw ID picker lets you search by product ID or title).
• Set the Display order field: this controls the sort order. Lower numbers appear first (e.g., set your top recommendation to 1, the next to 2, etc.).
• Save the product when you're done adding all recommended items.

Step 3: Display Sorted Recommendations in Your Templates #

To show the sorted recommended products on your frontend, fetch them ordered by the display_order field in your view:

from django.shortcuts import get_object_or_404
from oscar.core.loading import get_model

Product = get_model('catalogue', 'Product')

def product_detail(request, product_id):
    product = get_object_or_404(Product, pk=product_id)
    # Get recommended products sorted by display_order (ascending)
    recommended_products = product.related_products.order_by('display_order')
    return render(request, 'catalogue/product_detail.html', {
        'product': product,
        'recommended_products': recommended_products,
    })

Then in your template, loop through them:

{% if recommended_products %}
    <h3>Recommended Products</h3>
    <div class="recommended-products-grid">
        {% for item in recommended_products %}
            <div class="product-card">
                <a href="{{ item.get_absolute_url }}">
                    <img src="{{ item.primary_image.original.url }}" alt="{{ item.title }}">
                    <p>{{ item.title }}</p>
                    <span>{{ item.price }}</span>
                </a>
            </div>
        {% endfor %}
    </div>
{% endif %}

That's it! You should now be able to add recommended products in the admin and control their display order easily.
