What you're doing here is saving the original News object (not a Comment) after settings some random properties on the comments_set.
Basically you're shooting blanks :)
# fix this part.
news_article = get_object_or_404(models.News, id=newsId)
comment = models.Comment(
name=request.POST.get('comment_name' , ''),
text=request.POST.get('comment_text',''),
news=news_article
)
comment.save()
The comment_set is used to select all the related comments to the given News article.
See this django tutorial.
The above can also be shortened by using the create method like so:
models.Comment.objects.create(
name=request.POST['comment_name'],
text=request.POST['comment_text'],
news=news_article
)
This method also saves to the database.
