I am trying to save query result obtained in one view to session, and retrieve it in another view, so I tried something like below:

```
def default (request):
    equipment_list = Equipment.objects.all()

    request.session['export_querset'] = equipment_list

```

However, this gives me 

```
TypeError at /calbase/

<QuerySet [<Equipment: A>, <Equipment: B>, <Equipment: C>]> is not JSON serializable

```

I am wondering what does this mean exactly and how should I go about it? Or maybe there is alternative way of doing what I want besides using session?
