Many Duplicate Queries When Using Image Tag In Wagtail

I'm using Wagtail v1.13.1 for my website project. I'm trying to optimize db queries... models.py class ProductPage(Page): ... main_image = models.ForeignKey( 'wagta

Solution 1:

Try this.

prefetch_related('main_image__rendition_set')

This is assuming that the image templatetag can use the prefetched values correctly.
