How to add an model instance to a django queryset?

Question

It seems like a django queryset behaves somehow like a python list.

But it doesn\'t support list\'s .append() method as I know.

What I want to do is like:

Answer 1

No. A queryset is a representation of a query - hence the name - not an arbitrary collection of instances.

If you really need an actual queryset rather than a list, you could try accumulating the IDs of the objects you need and then getting the objects via an __in query:

list_of_ids = []
list_of_ids.append(my_id)
...
queryset = MyModel.objects.filter(id__in=list_of_ids)

This isn't very efficient, though.
