randomizing objects in the view with pagination

[John McClain]

I have a marketplace with many sellers selling the same 3 products in various values. In all the are 18 product type for sell on the platform with hundreds of sellers.

I was randomizing the product category page when loaded so that items from all sellers could appear on the page.

I was not using paginations and I have thousands of products so the page was obviously loading very slow.

I added pagination and let python manage the query instead of it happening on the server-side. This increased the page load but I lost my randomization.

The first page is the only page getting random items loaded. When using pagination to get to the 2nd page the items loading on that page are descending oldest to newest.

Does anyone have an idea how to manage randomizing items on each new page?

I am django core paginator

https://docs.djangoproject.com/en/3.0/ref/paginator/ 

Any ideas would be appreciated

Cheers,

John

Hello,

I have been using random module (django-random-queryset)  for site https://www.euroautozone.com. Performance is not bad.

here is the code

models.py 

class product(models.Model):
    ##Slug
    objects = RandomManager()

Views.py

       query = product.objects.filter(Q(title__icontains=query)

                                              |
                                              Q(description__icontains=query)
                                              |
                                              Q(customLabel__icontains=query)
                                              |
                                              Q(advertiserName__icontains=query)
                                              |
                                              Q(brand__icontains=query)
                                              ).filter(siteName__icontains=getCurrentSite(request)).distinct()
   
     all_information=query.random(1000)
