Multiple Lookup Fields

[SimoneBattaglin]

I'm quite new to django and I'd like to find an ID based on multiple lookup fields. Your library seems really good to me and I already got to do something very useful to me so I wanted to try this way, if possible.
I try to explain it a little better: I'd let the user choose one element of my table/model based on multiple columns that he have to choose consequently; something like "if car manufacturer is ford then those are the possible models, and if you choose this model then the id of the car is ***". Is that possible with your library?

PS: I found another issue here: #57
where a similar question was asked last summer, but there is still no answer so I try to ask here
