python - 自定义Django表单不显示-使用Wa

Wagtail博客网站-评论模型表单问题

我正在使用Wagtail创建一个博客站点，但遇到了麻烦。我已经在页面上添加了评论模型，我可以通过admin部分添加评论，并且评论会显示在正确的帖子上，但是由于某些原因，我创建的评论表单并未显示。这是我的相关代码。任何关于我做错地方的提示将不胜感激。

博客/models.py

class BlogPage(Page):
    date = models.DateField("Post date")
    intro = models.CharField(max_length=250)
    body = RichTextField(blank=True)
    #tag manager
    tags = ClusterTaggableManager(through=BlogPageTag, blank=True)

    #get feature image
    def main_image(self):
        gallery_item = self.gallery_images.first()
        if gallery_item:
            return gallery_item.image
        else:
            return None

    search_fields = Page.search_fields + [
        index.SearchField('intro'),
        index.SearchField('body'),
    ]

    content_panels = Page.content_panels + [
        MultiFieldPanel([
            FieldPanel('date'),
            FieldPanel('tags'),
        ], heading="Blog information"),
        FieldPanel('intro'),
        FieldPanel('body'),
        InlinePanel('gallery_images', label="Gallery images"),
    ]

    def serve(self, request):
        # Get current page
        post = self

        # Get comment form
        form = CommentForm(request.POST or None)

        # Check for valid form
        if form.is_valid():
            comment = form.save(commit=False)
            comment.post = post
            comment.save()
            return redirect(request.path)
        return render_to_response(self,
                {
                                      'post': post,
                                      'form': form,
                                  },
                                  context_instance=RequestContext(request))

class Comment(models.Model):
    post = models.ForeignKey(BlogPage, related_name='comments')
    author = models.CharField(max_length=250)
    text = models.TextField()
    created_date = models.DateTimeField(default=timezone.now)
    approved_comment = models.BooleanField(default=False)

    def approve(self):
        self.approved_comment = True
        self.save()

    def __unicode__(self):
        return self.text

    def __str__(self):
        return self.text

class CommentForm(forms.ModelForm):

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

现在我收到一个错误消息：

  File "/home/kenneth/development/web/sites/mysite/dynamicsalesops/blog/models.py", line 88, in serve
context_instance=RequestContext(request))
TypeError: render_to_response() got an unexpected keyword argument 'context_instance'

最佳答案

您的view_post函数从不使用。在Wagtail中，将页面呈现为HTML是由页面模型本身上的serve方法处理的，而不是由单独的视图函数处理的：http://docs.wagtail.io/en/v1.9/reference/pages/theory.html#anatomy-of-a-wagtail-request
