How to alphabetically sort the values in a many-to-many django-admin box?

Question

Hi, I have a simple model like this one:

class Artist(models.Model):
   surname = models.CharField(max_length=200)
   name = models.CharField(max_length=200, blank=True)
   slug = models.SlugField(unique=True)
   photo = models.ImageField(upload_to='artists', blank=True)
   bio = models.TextField(blank=True)  

class Images(models.Model):
   title = models.CharField(max_length=200)
   artist = models.ManyToManyField(Artist)
   img = models.ImageField(upload_to='images')

Well, I started to insert some Artists and then I went to the Images insert form. I found that the many-to-many artist box is unsorted:

• Mondino Aldo
• Aliprandi Bernardo
• Rotella Mimmo
• Corpora Antonio

Instead of:

• Aliprandi Bernardo
• Corpora Antonio
• Mondino Aldo
• Rotella Mimmo

How can I solve this issue? Any suggestion? Thank you in advance.

Set ordering on the Article's inner Meta class.

class Article(models.Model):
    ....

    class Meta:
        ordering = ['surname', 'name']
