Question

I have two models in my Django app file models.py like so:

class User(models.Model):
    user = models.IntegerField(primary_key=True,max_length=5)
    first_name = models.CharField(max_length=35)
    last_name = models.CharField(max_length=35)
class Device(models.Model):
    device_name = models.CharField(unique=True,max_length=30)
    user = models.ForeignKey('User')

Each Device can only have one User, but each User can have more than one Device.

In the admin interface, when I display a Device it shows the User in a drop-down list, but when I display the User, I don’t see the associated Device. How do I fix this so I can see the relationship from either side?

Answer 1

You need to use InlineModelAdmin objects

UPD

Should look like:

class DeviceInline(admin.TabularInline):
    model = Device

class UserAdmin(admin.ModelAdmin):
    inlines = [
        DeviceInline
    ]
