list_display a Many to Many field

[Fernando Rodríguez]

Hi,

I'm trying to display a many to many field in the admin interface.

This is my model:

class Book(models.Model):
title = models.CharField(maxlength = 100, db_index = True)
authors = models.ManyToManyField(Author)
Publisher = models.ForeignKey(Publisher)
publicationDate = models.DateField()

class Admin:
list_display = ('title', 'Publisher', 'publicationDate',
'authors' )
list_filter = ('Publisher', 'publicationDate')
search_fields = ('title')

def __str__(self):
return self.title

In the authors column, instead of the author's name(s), I get what seems
to be the __str__ of an object:
<django.db.models.fields.related.ManyRelatedManager object at 0x874352c>

How can I get this ManyRelatedManager to display what I want? O:-)

Thanks!

No, authors is the related manager, so it's all method returns a
QuerySet with all the relevant items.
