this Error is Coming due to i am importing my custome model template and built in Template

from template.models import Template
from django.template import Context, Template
def func1(request):

  template = **Template**.objects.get(template_default__exact=1)

def func2(request):            
      template = **Template** ("""link{{ request.get_host }}{% url 'detail' driver_id=driver_id %}""")

Same Template name with different import.One is built-in import and second is model import thats why attribute error is occuring.

Special Thanks to :
