注释不在Django应用程序中显示

I have a simple Django application which I would appreciate a fresh pair of eyes to help me fix this problem.

我有一个简单的Django应用程序,我很欣赏一双新的眼睛来帮助我解决这个问题。

I have been trying to add the comments functionality from the djangogirls tutorial to my app called 'timeline'.

我一直在尝试将djangogirls教程中的评论功能添加到我的应用程序“timeline”中。

So far I have added a comment model to my models.py:

到目前为止,我已经为我的models.py添加了一个评论模型:

class Comment(models.Model):
    post = models.ForeignKey('timeline.Photo', related_name='comments')
    author = models.ForeignKey(settings.AUTH_USER_MODEL, default=1)
    text = models.TextField()
    created_date = models.DateTimeField(default=timezone.now)

    def __unicode__(self):
        return self.text

    def __str__(self):
        return self.text

which already contains a photo model:

已包含照片模型:

class Photo(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL, default=1)
    title = models.CharField(max_length=120)
    slug = models.SlugField(unique=True)
    image = ProcessedImageField(upload_to=upload_location, 
        null=True, 
        blank=False,
        processors=[Transpose(), ResizeToFit(1000, 1000, False)],
        #processors=[Transpose(), ResizeToFit(width=960)],
        format='JPEG',
        options={'quality': 50},
        width_field="width_field",
        height_field="height_field")
    height_field = models.IntegerField(default=0)
    width_field = models.IntegerField(default=0)
    description = models.TextField()
    updated = models.DateTimeField(auto_now=True, auto_now_add=False)
    timestamp = models.DateTimeField(auto_now=False, auto_now_add=True)

    def __unicode__(self):
        return self.title

    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse("timeline:detail", kwargs={"slug": self.slug})

    class Meta:
        ordering = ["-timestamp", "-updated"]

I am struggling to make the comments appear within my html but so far i have followed the instructions and used:

我正在努力使评论出现在我的HTML中,但到目前为止我已按照说明使用:

{% for comment in post.comments.all %}
    <div class="comment">
    <div class="date">{{ comment.created_date }}</div>
    <strong>{{ comment.author }}</strong>
    <p>{{ comment.text|linebreaks }}</p>
    </div>
{% empty %}
    <p>No comments here yet :(</p>
{% endfor %}

view:

def photo_detail(request, slug=None):
    if not request.user.is_authenticated():
        return HttpResponseRedirect("/accounts/login")

    instance = get_object_or_404(Photo, slug=slug)

    share_string = quote_plus(instance.description)
    context = {
        "title": instance.title,
        "instance": instance,
        "share_string": share_string,
    }

    return render(request, "photo_detail.html", context)

I have added the comment model to my admin and I am able to add comments ok but they are simply not displaying and it is driving me nuts. I am sure a fresh pair of eyes will spot this easily. Using Django 1.9 and if any more code required let me know!

我已将评论模型添加到我的管理员,我可以添加评论,但它们只是没有显示,这让我疯狂。我相信一双新鲜的眼睛很容易发现这一点。使用Django 1.9,如果需要更多代码,请告诉我!

You are not passing any object called post into the template for rendering.

您没有将任何名为post的对象传递到模板中进行渲染。

You need to change either the context passed from the view:

您需要更改从视图传递的上下文:

context = {
    "title": instance.title,
    "photo": instance,
    "share_string": share_string,
}

Or change the code in the template:

或者更改模板中的代码:

{% for comment in instance.comments.all %}

(one or the other, not both)

(一个或另一个,不是两个)

I would suggest to change the context in the view to use the more meaningful name photo.

我建议更改视图中的上下文以使用更有意义的名称照片。
