时间分类：

1.用mysql存储

　　#date_format

 date_list = models.Article.objects.filter(blog=blog_obj).extra(
        select={"ctime": "date_format(create_time,'%%Y-%%m')"}).values("ctime").annotate(ct=Count("nid"))
   

2.用db.sqlite 存储

　　#strftime

date_list = models.Article.objects.filter(blog=currentBlog).extra(
        select={"ctime":"strftime('%%Y-%%m-%%d',create_time)"}).values("ctime").annotate(ct=Count('nid'))
   

前端展示：

{% for item in date_list %}
       <li><a href="">{{ item.ctime }}({{ item.ct }})</a></li>
{% endfor %}

分类过滤查询

urls.py

url("^home/(?P<site>w+)/article/(?P<condition>(category)|(tag)|(date))/(?P<para>w+-?w*-?w*)", views.home),

#考虑到 三类标签（特别是  date）

views.py

def home(request,*args,**kwargs):

    site = kwargs.get('site')

    #获取用户对象
    user = models.UserInfo.objects.filter(username=site).first()

    # if not user:  #没有此对象，返回 404
    #     return render(request,'NotFound.html')


    # 1.获取当前站点对象
    currentBlog = models.Blog.objects.filter(user=user).first()

    # 2.获取当前站点文章
    article_list =models.Article.objects.filter(blog=currentBlog)
    # print(article_list)


    #3.获取当前站点标签

    tag_list = models.Article.objects.filter(blog=currentBlog).values_list('tags__nid','tags__title').annotate(Count('tags__title'))
    # print('tag_list',tag_list)


    #4.查询当前站点的 Category下每一个分类下的名称以及对应的文章数

    category_list = models.Article.objects.filter(blog=currentBlog).values_list("category__nid", "category__title").annotate(
        cc=Count("nid"))
    # print('category_list',category_list)


    #获取datetime列表

    date_list = models.Article.objects.filter(blog=currentBlog).extra(
        select={"ctime":"strftime('%%Y-%%m-%%d',create_time)"}).values("ctime").annotate(ct=Count('nid'))

    # print(date_list)  #<QuerySet [{'ctime': '2017-09-08', 'ct': 5}, {'ctime': '2017-09-09', 'ct': 1}]>
