here is the models page
In this picture, only the title shows up on here, I used:
def __unicode__(self):
return self.title;
If you want to include all fields without typing all fieldnames, you can use
list_display = BookAdmin._meta.get_all_field_names()
The drawback is, the fields are in sorted order.
Edit:
This method has been deprecated in Django 1.10 See Migrating from old API for reference. Following should work instead for Django >= 1.9
for most cases -
list_display = [field.name for field in Book._meta.get_fields()]
