我想使用django createview为我的文章添加评论。目前，我可以毫无问题地添加文章。我可以添加评论。但我无法将评论添加到正确的文章中。
我已经在这两天了。我真的很想用cbv这样做，因为我正在努力学习。任何帮助解释我做错了什么以及如何纠正它都将非常感激。

答案 0 :(得分：2)
我认为这是你想要的
class CreateArticleComment(CreateView):
model = ArticleComment
fields = ('text',)
def post_valid(self, form):
article = get_object_or_404(Article,
slug=article.slug) # Replaced 'Post' with 'Article'
articlecomment = form.save(commit=False)
articlecomment.author = self.request.user
articlecomment.article = article
articlecomment.save()
return redirect('articles:article-detail', slug=article.slug)
def get_success_url(self):
return reverse_lazy('articles:article-list')
答案 1 :(得分：0)
您正在将查询集分配给外键字段：
Ord线
let logo = UIImage(named: "logo.png")
let imageView = UIImageView(image:logo)
self.navigationItem.titleView = imageView
需要更改为
class CreateArticleComment(CreateView):
model = ArticleComment
fields = ('text',)
def post_valid(self, form):
post = get_object_or_404(Post,
slug=article.slug)
article = Article.objects.all() <----------------------------
articlecomment = form.save(commit=False)
articlecomment.author = self.request.user
articlecomment.article = article
articlecomment.save()
return redirect('articles:article-detail', slug=article.slug)
def get_success_url(self):
return reverse_lazy('articles:article-list')
由于我们要为特定文章分配评论，该文章的子句在当前网址中显示为：
http://example.com/ sl弹 /评论/
这将使我们能够获得用户发表评论的相关文章。
