please help to understand.

I have the next models :

class TagsList(models.Model):
    tags_list = models.CharField(max_length=30)

    def __str__(self):
        return self.tags_list

class Blog(models.Model):
    title = models.CharField(max_length=200)
    content = models.TextField()
    pub_date = models.DateTimeField(auto_now_add=True)
    tags = models.ManyToManyField(TagsList)

how i can get related tags by object (in my case object with post_id)? It's my view file :

def single(request, post_id):
    object_post = Blog.objects.get(id=post_id)
    tags = TagsList.objects.all()
    content = {
        'object_post': object_post,
        'tags': tags,
    }
    return render(request, 'single.html', content)

I tried all cases, but how to include to content exactly tags which are related to this object, don't know. Thanks all, for the help.

P.S. Using django 1.11
