how to create an empty queryset and to add objects manually in django [closed]

Question

I need to create a queryset and to add manually some objects that i've got from different queries results in order to display it in a table. I uses xx=set() but it doesn't do the job.

Answer 1

You can do it in one of the following ways:

from itertools import chain #compute the list dynamically here: my_obj_list = list(obj1, obj2, ...) #and then  none_qs = MyModel.objects.none() qs = list(chain(none_qs, my_obj_list)) 

You could also do:

none_qs = MyModel.objects.none() qs = none_qs | sub_qs_1 | sub_qs_2 

However, This would not work for sliced querysets

Answer 2

You can't do that. A queryset is a representation of a database query. You can't add items to it manually.

But if you need an arbitrary ordered collection of model instances, just use a list.
