I really appreciate if anybody could give me an advice about form_valid. Here is what I want to do. I am making a simple blog. I am making simple features: 1) only superuser can create articles. 2) logged-in users can make comments to articles.
I followed along tutorials and mostly done. *But last thing I want to do is that when users make comments to any articles, I want author field and article field to be automatically set.* *Currently, users need to choose author field and article field to make comments as well as comment texts.* The tutorial that I followed along uses form_valid and by using form_valid, now I don't need to choose author. But I have been struggling with how to automatically set article field by using form_valid. I have a simple models.py and views.py below. <models.py> class Article(models.Model): title = models.CharField(max_length=255) body = models.TextField() date = models.DateTimeField(auto_now_add=True) author = models.ForeignKey( get_user_model(), on_delete=models.CASCADE, ) def __str__(self): return self.title def get_absolute_url(self): return reverse('article_detail', args=[str(self.id)]) class Comment(models.Model): # new article = models.ForeignKey( Article, on_delete=models.CASCADE, related_name = 'comments', ) comment = models.CharField(max_length=140) author = models.ForeignKey( get_user_model(), on_delete=models.CASCADE, ) def __str__(self): return self.comment def get_absolute_url(self): return reverse('article_list') <views.py> ...(not showing all) #for comment class ArticleCommentCreateView(LoginRequiredMixin, CreateView): model = Comment template_name = 'article_comment_new.html' fields = ('comment',) login_url = 'login' def form_valid(self, form): form.instance.author = self.request.user *form.instance.article = self.request.article* return super().form_valid(form) I keep getting errors with this code. I know that *form.instance.article = self.request.article* is something wrong, but I am having hard time to figure out how to set article field to be automatically set. Please give any advice about this. I really appreciate. Looking forward to hearing from anyone.
