【问题描述】:
我想实现一个 ajax 评论系统。
urls.py:
(r'^comment/(\d+)/$', comments),
views.py:
def comments(request,feed):
if request.method == 'POST':
feed=Feed.objects.get(pk=feed)
form = CommentForm(request.POST)
if form.is_valid():
comment, created = Comment.objects.get_or_create(
feed=feed,
msg=form.cleaned_data['msg'],
ip=request.META['REMOTE_ADDR']
)
comments=Comment.objects.filter(feed=feed)
form=CommentForm()
variables=RequestContext(request,{'comments': comments,'feed': feed,'form':form,})
if 'HTTP_REFERER' in request.META:
return HttpResponseRedirect(request.META['HTTP_REFERER'])
return render_to_response('comment_page.html', variables )
#return HttpResponseRedirect('/view/')
else:
form=CommentForm()
feed=Feed.objects.get(pk=feed)
comments=Comment.objects.filter(feed=feed).reverse()
variables=RequestContext(request,{'comments': comments,'feed': feed,'form':form,})
return render_to_response('comment_page.html', variables )
模板:
<div id="commentbox" style="display:none;">
<form class="comment" method="post" action="/comment/{{feed.id}}/">
{{cform.as_p}}
<input class="post" type="submit" value="post" />
</form>
</div>
</br>
<h3></h3><button class="ccc">Show/Hide Comment</button> {{feed.comment_set.count}} Comments
<div id="commentlist" class="commentlist" style="padding-left:10px;"><ul style="list-style-type:square;">
{% for c in feed.comment_set.all %}
<li>{{c.msg}}</li>
{% endfor %}
</ul>
</div>
在不刷新页面的情况下,我应该包含哪些代码才能将 cmets 添加到评论列表 li 字段中。我是ajax新手。请帮忙。谢谢
