Djangorestframework: is it possible to deserialize only specific fields of incoming JSON?
You need to look into using the required=False flag on the device field in your serializer class.
I need to deserialize incoming JSON.  The incoming JSON will be transformed to a Django model object called AdvancedUser.  An AdvancedUser has a one to one with a Device model.  
When I POST my incoming JSON, I'm getting errors that say "Device field is required".  
The Device field is optional in my AdvancedUser model declaration code.
How do I get rid of this error?  It's OK if no Device field is passed in.
