[Answer]-Passing User attributes as a variable in Django Template

User and UserProfile are two different models. But since you have a OneToOneField from UserProfile to User, you can also follow it back.

<h1>User is {{ user }} from {{ user.userprofile.location }}</h1>

From the docs on OneToOneField

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