I have a List model which holds all of the lists used throughout the  
app. This model has the following fields: id, list, value, sequence.  
To fetch a list of states, you could do something like  
List.find\_by\_list(“states”).

Now I also have a Record model which holds a reference to a User  
model. I also want it to link back to three different lists (state,  
country, and user\_group). These references are independent of each  
other and should be linked by a list ID. Any ideas on how to  
construct the Record model and database structure?

Thanks in advance!
