Python Django从views.py动态获取PK

我有一个视图，可以呈现注释表单和模板：

视图.py

def news(request):
    if request.method == "POST":
        form = CommentForm(request.POST)
        if form.is_valid():
            comment = form.save(commit=False)
            comment.post = Article.objects.get(pk=2)
            print(comment.post)
            comment.author = request.user.username
            comment.save()
            return HttpResponseRedirect('')
    else:
        form = CommentForm()
    return render(request, '../templates/news.html', context={"form": form})

class Comment(models.Model):
    post = models.ForeignKey(Article, on_delete=models.CASCADE, related_name='comments', blank=True)
    author = models.TextField()
    text = models.TextField()

    def __str__(self):
        return self.text

class CommentForm(ModelForm):
    class Meta:
        model = Comment
        fields = ('text',)

型号.py

def news(request):
    if request.method == "POST":
        form = CommentForm(request.POST)
        if form.is_valid():
            comment = form.save(commit=False)
            comment.post = Article.objects.get(pk=2)
            print(comment.post)
            comment.author = request.user.username
            comment.save()
            return HttpResponseRedirect('')
    else:
        form = CommentForm()
    return render(request, '../templates/news.html', context={"form": form})

class Comment(models.Model):
    post = models.ForeignKey(Article, on_delete=models.CASCADE, related_name='comments', blank=True)
    author = models.TextField()
    text = models.TextField()

    def __str__(self):
        return self.text

class CommentForm(ModelForm):
    class Meta:
        model = Comment
        fields = ('text',)

forms.py

def news(request):
    if request.method == "POST":
        form = CommentForm(request.POST)
        if form.is_valid():
            comment = form.save(commit=False)
            comment.post = Article.objects.get(pk=2)
            print(comment.post)
            comment.author = request.user.username
            comment.save()
            return HttpResponseRedirect('')
    else:
        form = CommentForm()
    return render(request, '../templates/news.html', context={"form": form})

class Comment(models.Model):
    post = models.ForeignKey(Article, on_delete=models.CASCADE, related_name='comments', blank=True)
    author = models.TextField()
    text = models.TextField()

    def __str__(self):
        return self.text

class CommentForm(ModelForm):
    class Meta:
        model = Comment
        fields = ('text',)

在views.py中，comment.post被分配给文章对象，我希望动态应用pk。我尝试在模板中这样做，将{{article.pk}}放在模板中输出文章对象的正确pk，但我不确定如何将其应用到表单中

模板看起来很简单：文章对象，下面是评论表单

---

问题很简单，我希望news（request）函数动态应用当前文章对象的pk，以便将评论转到正确的帖子。

如果路径是唯一的，您可以使用该路径，也可以添加一个隐藏字段并将文章pk设置为值：

<input name="post" type="hidden" value={{ article.pk }} />

您可以从视图中的验证数据访问它。

您可以通过post请求检索

pk

，只需在表单中添加一个输入字段，其中包含news.pk作为值。
