Display products on homepage in Django-Oscar?

Question

Django

When using Django-Oscar, there was a clear problem with displaying a list of products on the main page.
The standard method doesn't work because of the session check protection (request.strategy.fetch_for_product(product)):
When I fetch the products in the catalog everything works fine. When I try to do this for the main page, either the list is empty or an error occurs.
If you use the method from the documentation (inserting a block of content), an error occurs all the time:
'str' object has no attribute 'strategy'
The error is in this code that checks the session:

from django import template

register = template.Library()


@register.assignment_tag
def purchase_info_for_product(request, product):
    if product.is_parent:
        return request.strategy.fetch_for_parent(product)

    return request.strategy.fetch_for_product(product)


@register.assignment_tag
def purchase_info_for_line(request, line):
    return request.strategy.fetch_for_line(line)

Please suggest working examples or workarounds.
UPD: The bug turned out to be in Django version=1.10.5. After rolling back to version 1.9.12, the error disappeared.
Goods are displayed on the main page through the automatic list of goods block.

Answer 1

So far I have found this WORKAROUND SOLUTION. Through app.py, redefine the home page url by replacing it with a directory. In this version, the goods are shown without any errors.
But there was another problem. Updating the cart quantity raises a 500 error with reference to this piece of code:
def purchase_info_for_line(request, line):
return request.strategy.fetch_for_line(line)
Checking for the error shows that no strategy is passed in the line.
