django models without database

Question

I know the automatic setting is to have any models you define in models.py become database tables.

I am trying to define models that won't be tables. They need to store dynamic data (that we get and configure from APIs), every time a user searches for something. This data needs to be assembled, and then when the user is finished, discarded.

previously I was using database tables for this. It allowed me to do things like "Trips.objects.all" in any view, and pass that to any template, since it all came from one data source. I've heard you can just not "save" the model instantiation, and then it doesn't save to the database, but I need to access this data (that I've assembled in one view), in multiple other views, to manipulate it and display it . . . if i don't save i can't access it, if i do save, then its in a database (which would have concurrency issues with multiple users)

I don't really want to pass around a dictionary/list, and I'm not even sure how i was do that if I had to.

ideas?

Thanks!

Another option may be to use:

class Meta:
    managed = False

to prevent Django from creating a database table.
