How to convert a list in to queryset django

Question

I have a queryset(which is filtered actually) as below

posts = [, , , , 

        

Answer 1

The previous answers are correct if each list item already exists in the database, but sometimes this is not the case. In this case you can create a queryset stub based on the list and implement queryset-methods and queryset-properties as needed.

class ListAsQuerySet(list):

    def __init__(self, *args, model, **kwargs):
        self.model = model
        super().__init__(*args, **kwargs)

    def filter(self, *args, **kwargs):
        return self  # filter ignoring, but you can impl custom filter

    def order_by(self, *args, **kwargs):
        return self

qs = ListAsQuerySet(custom_list, model=Post)
