Can't make a bunch of comments in Django?

Question

Django

Hello.
Unable to properly link comments to posts. Now it turns out that the comment to one news is displayed on all other news. It is necessary that there was every comment to your news.
model:

class Comments(models.Model):
    class Meta():
        db_table = 'comments'
        verbose_name = 'Комментарий'
        verbose_name_plural = 'Комментарии'

    comments_text = models.TextField(verbose_name='Текст комментария')
    comments_blogpost = models.ForeignKey(BlogPost)

view: display all news and comment filter

def full_slug(reguest, slug):
    comment_form = CommentForm
    form = comment_form
    comments = Comments.objects.filter()
    te = get_object_or_404(BlogPost, slug=slug)
    return render(reguest, 'full.html', {'te': te, 'form': form, 'comments': comments, 'username': auth.get_user(reguest).username})

view: Add comments

def addcomment(reguest, one_id):
    if reguest.POST and ('pause' not in reguest.session):
        form = CommentForm(reguest.POST)
        if form.is_valid():
            comment = form.save(commit=False)
            comment.comments_blogpost = BlogPost.objects.get(id=one_id)
            form.save() # Сохраняем
            return_path = reguest.META.get('HTTP_REFERER','/')
            reguest.session.set_expiry(10) .
            reguest.session['pause'] = True 
    return redirect(return_path)

urls:

url(r'^(?P<slug>[-\w]+)/$', views.full_slug, name='full_slug'), # Вывод новостей
url(r'^addcomment/(?P<one_id>\d+)/$', views.addcomment), # Добавление коммента

In general, in the view, I can’t prescribe a filter in this line comments = Comments.objects.filter() so that the comment is attached to the desired news. Now it turns out that all the comments come out in all the news.
I tried this:
comments = Comments.objects.filter(comments_blogpost_id=slug) but I get an error. The output should be only by id, like this
comments = Comments.objects.filter(comments_blogpost_id=one_id)
But if you use the one_id parameter instead of slug, then there will be links in the news like this full/22 not a human-readable url.
Tell me where is my mistake? I'm just learning django and may have made a bunch of mistakes and got confused.

If we talk about the output view, then first you need to get the "blog post" itself, and then filter the comments by it, i.e. just swap 2 lines and add a filter:

def full_slug(reguest, slug):
    comment_form = CommentForm
    form = comment_form
    te = get_object_or_404(BlogPost, slug=slug)
    comments = Comments.objects.filter(comments_blogpost=te)
    return render(reguest, 'full.html', {'te': te, 'form': form, 'comments': comments, 'username': auth.get_user(reguest).username})
