貌似Django從版本1.6開始就放棄了對自帶的comments的使用，具體原因未查，但是現在使用Django的內部的模組也可以實現評論功能，那就是藉助於forms模組，下面是我的一個小例子。
環境準備
•作業系統： windows 7 64 位元旗艦版
•IDE：PyCharm 2016.1
•Python :2.7.11
•Django :1.9.6

# Create your models here.
TOPIC_CHOICES = (
('level1','Bad'),
('level2','SoSo'),
('level3','Good'),
)
class RemarkForm(forms.Form):
subject = forms.CharField(max_length=100,label='Mark Board')
mail = forms.EmailField(label='email')
topic = forms.ChoiceField(choices=TOPIC_CHOICES,label='choose one topic')
message = forms.CharField(label='content for mark',widget=forms.Textarea)
cc_myself = forms.BooleanField(required=False,label='watch this tie')
class Remark(models.Model):
subject = models.CharField(max_length=100)
mail = models.EmailField()
topic = models.CharField(max_length=100)
message = models.CharField(max_length=300)
cc_myself = models.BooleanField()
def __unicode__(self):
return self.subject
class Meta:
ordering = ['subject']
admin.site.register([Remark,])url映射檔案urls.py

# Database

DATABASES = {

'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
}
}這裡我們在瀏覽器下輸入
127.0.0.1:8000/admin就可以看到下面
然後輸入127.0.0.1:8000/
這樣，除了沒有美化介面，其餘的都完成了呢。
這裡雖然是個很簡單的小例子，但是我也從中發現了自己的一些概念上的問題，比如說對於模型設計的不合理，因為沒有評論時間，這就顯得很尷尬了。
然後是
// 创建数据库表结构 python manage.py makemigrations python manage.py migrate // 按照提示进行操作即可，目的是为了创建一个超级管理员 python createsuperuser //在自带的开发服务器上运行我们的项目 python manage.py runserver
好了，今天就介紹到這裡吧，由於本人能力一般，程式碼或邏輯有錯的地方，歡迎大家批評指正！
