裝飾器：
加入要給一些界面加一個登錄權(quán)限：
直接上代碼

在utils里面：

#裝飾器，判斷用戶是否登錄
def require_login(fn):

    def inner(request,*args, **kwargs):
        if request.session.has_key("loginUser"):
            logging.warning("該用戶已經(jīng)登錄竣灌，視圖函數(shù)正常訪問")
            return fn(request, *args, **kwargs)
        else:
            logging.warning("請先登錄Ｄ羯场！")
            return render(request,"demo/login.html", {"msg": "當(dāng)前操作必須登錄初嘹，請先登錄系統(tǒng)"})
    return inner

然后在views里面可以直接調(diào)用

分頁：

django提供了一個非常簡單的分頁方法及汉，直接上代碼：
from django.core.paginator import Paginator
def index(request):
   # logger = logging.getLogger("django")
    #logger.warning("首頁開始運行了……")

    #在緩存中獲取數(shù)據(jù)
    articles =  cacheUtils.getAllArticle()
    
    pageSize = int(request.GET.get("pageSize", settings.PAGE_SIZE))
    pageNow = int(request.GET.get("pageNow", 1))
    paginator = Paginator(articles, pageSize)
    page = paginator.page(pageNow)

    return render(request, "blog/index1.html", {"page": page, "pageSize": pageSize})


在前端界面上：
<div class="col-md-8">
            <!--<div class="page-header">-->
            <!--<h3>熱門文章 <small>這里能找到技術(shù)前沿的各位大神的文章內(nèi)容</small></h3>-->
            <!--</div>-->
            <div class="row author-article">
                <div class="tab-content">
                    <div role="tabpanel" class="tab-pane active" id="home">
                        {% for at in page.object_list %}
                        <div class="media">
                            <div class="media-body">
                                <h4 class="media-heading"><a href="{% url 'demo:show_article' at.id %}">{{at.title}}</a></h4>
                                {{at.content | safe}}
                            </div>
                            <div class="media-left media-middle">
                                <a href="#">
                                    <img class="media-object " src="/static/demo/image/articles/1.jpg" alt="圖片">
                                </a>
                            </div>
                            <div class="media-bottom text-muted">
                                <span class="glyphicon glyphicon-eye-open">169</span>
                                <span class="glyphicon glyphicon-comment">18</span>
                                <span class="glyphicon glyphicon-heart">200</span>
                                <span>&nbsp;{{at.publishtime}}</span>

                            </div>
                        </div>
                        {% endfor %}
                    </div>
                    <nav aria-label="Page navigation">
                      <ul class="pagination">

                          {% if page.has_previous %}
                           <li>
                              <a href="/demo/index?page_now={{page.previous_page_number}}" aria-label="Previous">
                                <span aria-hidden="true">&laquo;</span>
                              </a>
                            </li>
                          {% endif %}

                          {% for p in page.paginator.page_range %}
                            <li><a href="/demo/index/?page_now={{p}}">{{p}}</a></li>
                          {% endfor %}

                           {% if page.has_next %}
                           <li>
                               <a href="/demo/index?page_now={{page.next_page_number}}" aria-label="Next">
                                   <span aria-hidden="true">&raquo;</span>
                               </a>
                            </li>
                          {% endif %}

                      </ul>
                    </nav>
                </div>
            </div>
        </div>

基本上都是固定用法，可以直接照搬代碼屯烦。
