django - 'QuerySet' object has no attribute ERROR, trying to get related data on ManyToMany fields -

i have following models:

class tag(models.model):     tag_name = models.charfield(max_length=250)     tagcat = models.foreignkey('tagcat')  class subject(models.model):     user = models.manytomanyfield(user)     tags = models.manytomanyfield(tag)  class tagcat(models.model):     cat_name = models.charfield(max_length=100) 

so have subject, has tag. want loop subjects , appropriate tags, trying construct right view. far, have:

def home(request):     user1 = subject.objects.filter(id=1)     print(user1.tags.all()) 

i expect tags of user through print statement, instead error

'queryset' object has no attribute 'tags'

how getting 'subject' objects respective tags , pass them template?

(ideally subjects. did 1 here, simplify process of troubleshooting)

filter returns queryset (as may have guessed), want get instead

user1 = subject.objects.get(id=1) 

if subject not exist subject.doesnotexist exception. there's get_object_or_404 shortcut in django.shortcuts useful if you're grabbing object displayed in way , want return 404 if not available.
