From OneToOneField's documentation:

If you do not specify the related_name argument for the OneToOneField, Django will use the lowercase name of the current model as default value.

So, you'll have to access the related Adminuser instance as:

request.user.adminuser

If you want to access it using just admin, as mentioned in the docs, you'll have to make use of the related_name argument:

class Adminuser(models.Model):
    user = models.OneToOneField(User, related_name='admin' ...)
    ...

# request.user.admin will work now

Update

RelatedObjectDoesNotExist exception is raised when the related object doesn't exist in the database (this is often the case when related field can be null). Since there's no AttributeError this time, that means Django did recognise the admin attribute; so, that issue is fixed.

You'll have to handle RelatedObjectDoesNotExist exception everywhere you're accessing the related attribute.

from django.core.exceptions import ObjectDoesNotExist

try:
    admin = requset.user.admin
except ObjectDoesNotExist:
    admin = # set some other value ...
