Django Query result comparison with if statement

Need to check browser changeable values with using browser inspect and enter random id into url which is in button so I'm not really pro about django and stuff.I make a validation of data which is going to updated or deleted that can checked by tenantid for instance Im going press update on a single line of record and mechanics going to check if the record tenantid is equal to my tenant id or not. problem is about I cant compare query result to int value.

if any better approach about this I'ill be glad to hear, thank you have a good days.

@login_required()  def customer_update(request, pk):
    customer = get_object_or_404(Customer, pk=pk)
    valueOwnerTenantid = Customer.objects.values_list('tenantid',   flat=True).filter(id=pk)
    print(valueOwnerTenantid)
    print(request.user.tenantid)
    print(valueOwnerTenantid.query)

    if number(valueOwnerTenantid) == number(request.user.tenantid):
        if request.method == 'POST':
            print('Equal and POST')
            form = CustomerForm(request.POST, instance=customer)
        else:
            print('Equal and Get')
            form = CustomerForm(instance=customer)
            return save_customer_form(request, form, 'customer_update_partial.html')
    else:
