Question

The default choice field display of a reference property in appengine returns the choices
as the string representation of the entire object. What is the best method to override this behaviour? I tried to override str() in the referenced class. But it does not work.

Answer 1

The correct way would be to override the __unicode__ method of the class, like:

def __unicode__(self):
    return self.name

where name is the value that you want to display.
