Question

我正在构建一个django'留言簿'应用程序，让访问者留下评论。但我一直得到'django导入错误：没有名为comment的模块'。我该怎么解决？当我单击提交按钮时会弹出错误回溯，但奇怪的是用户输入在DB中保存得很好。

回溯：

ImportError at /comment/1/like/

Views.py：

from django.shortcuts import render, redirect, get_object_or_404
from guestbook.models import Comment

def index(request):
    context = {
                "comments" : Comment.objects.all()
    }
    return render(request, "index.html", context)

def comment_submit(request):
    try:
        name = request.POST["name"]
        contents = request.POST["contents"]
    except (KeyError):
        return redirect('index')
    else: 
        comment = Comment(name = name, contents = contents)
        comment.save()
        return redirect('index')

def comment_like(request, comment_id):
    comment = get_object_or_404(Comment, id=comment_id)
    comment.like = comment.like + 1
    comment.save()
    return redirect('index')

Models.py：

from django.db import models

    like     = models.IntegerField("Like", default=0)

    def __str__(self):
        return "%s: %s" % (self.name, self.contents)

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    url(r'^$', 'guestbook.views.index', name="index"),
    url(r'^comment/submit/$', 'guestbook.views.comment_submit', name='comment_submit'),
    url(r'^comment/like/$', 'guestbook.views.comment_like', name='comment_like'),
    url(r'^comment/(?P<comment_id>\d+)/like/$', 'comment.views.comment_like'),
