The admin app is clever enough to figure out a lot of things from your model automatically. However, sometimes the inferred information can be improved. This usually involves adding an attribute or a method to the model itself (rather than at the ModelAdmin class).
Let's first take a look at an example that enhances the model for better presentation, including the admin interface:
# models.py
class SuperHero(models.Model):
name = models.CharField(max_length=100)
added_on = models.DateTimeField(auto_now_add=True)
def __str__(self):
return "{0} - {1:%Y-%m-%d %H:%M:%S}".format(self.name,
self.added_on)
def get_absolute_url(self):
return reverse('superhero.views.details', args=[self.id])
class Meta:
ordering = ["-added_on"]
verbose_name = "superhero"
verbose_name_plural = "superheroes"Let's take a look at how admin uses all these non-field attributes...
