Re: Display the __str__ or __unicode__ of an objet on deletion of one of its ManyToManyField

Hello,

On Django 1.8 + Python 2.7.11, I have declared in Django admin.py an oeuvre class with a ManyToManyField (types) to an TypeOeuvre class.

class Oeuvre(models.Model):      titre = models.CharField(max_length=510)      types = models.ManyToManyField('TypeOeuvre',                                     blank=True,                                     verbose_name="Type(s) de l'œuvre")      class Meta:          ordering = ['titre']        def __unicode__(self):          return "{0} [{1}]".format(self.titre[:200], self.id)  

  class TypeOeuvre(models.Model):      intitule = models.CharField(max_length=100, verbose_name='Intitulé')      commentaire = models.CharField(max_length=255,                                     verbose_name='Commentaire',                                     blank=True)        class Meta:          ordering = ['intitule']          verbose_name = "Type d'œuvre"          verbose_name_plural = "Types d'œuvres"        def __unicode__(self):          return self.intitule

When I try to delete a TypeOeuvre object in Django Admin for which relations to one oeuvre exists, the "Are you sure?" warning do not explicitly mention the name of the oeuvre but displays a list of:

Oeuvre-typeoeuvre relationship: Oeuvre_types object

I also reproduced the problem on Django 1.10 + Python 3.4.5 and using __str__ instead of __unicode__.

Is there a way to display the name of the oeuvres linked to the type ?

Thanks,
