Permission in Django across native to custom table

Question

Django creates basic auth tables like auth_user, auth_user_groups, auth_user_user_permissions, etc.

I currently have (1) db with custom tables like Tld, etc. Tld standing for Top Level Domain.

But, django has created its own tables for permissions above. How can I tie a specific PK in auth_user to my Tld table?

I know, I know a FK->PK relationship, but this doesn't come out of the box.

Basically, I want to check if a user has a tld currently (which should just be a JOIN) on the two tables, but as the db currently stands <any-django-out-of-box-auth> table doesn't know about any custom table I've made.

How do I get this process working, for example, I have a view that creates new records for Tlds:

def Scan(request):
    form = SubmitDomain(request.POST or None) # A form bound to the POST data
    if request.method == 'POST': # If the form has been submitted...
        if form.is_valid(): # If form input passes initial validation...
            domainNmCleaned = form.cleaned_data['domainNm']  ## clean data in dictionary
            form.save() #save cleaned data to the db from dictionary
            try:
                return HttpResponseRedirect('/S/?domainNm=' + domainNmCleaned)
            except:
                raise ValidationError(('Invalid request'), code='300')
    else:
        form = SubmitDomain()

    return render(request, 'myapp/index.html', {
        'form' : form 
    })

How do I get it to also insert the currently logged in User id in another table called Tld__User? So that, when I join Tld with the system created Auth_User table I can see if a user has any Tld?

Thank you!

I found this after some further research:

from django.contrib.auth.models import User

class Employee(models.Model):
    user = models.OneToOneField(User)
    department = models.CharField(max_length=100)
