Given a model instance and the name of one of its fields as a string,
how can I get/put a value in that field?

The methods might look like this ...

def get_value(obj, fldname):

    ...

    return value

def put_value(obj, fldname, value):

    pass

Thanks for any hints

Mike

getattr(instance, key) to get the value

setattr(instance, key ,value) to put the value, and remember to do instance.save() otherwise it won't actually be changed.
