1. 引入messages模块

from django.contrib import messages

2. 把messages写入view中

@csrf_exempt
def search(request):
 if request.method == 'GET':
 bookname = request.GET.get('bookname')
 bookinfo = Book.objects.filter(bookname=bookname)
 is_staff = request.user.is_staff
 username = request.user.username
 gonggao = Gonggao.objects.all().order_by("-c_time")
 liuyanban_all = liuyan.objects.all().order_by("-c_time")
 c2 = JieInfo.objects.filter(u_name=username, book_name=bookname)
 c3 = JieInfo.objects.filter(u_name=username).count()
 if username == '':
 messages.error(request, '亲，请您先登录,才能使用该功能。')
 return redirect('/')
 else:
 if bookname == '':
 messages.error(request, '亲，搜索内容不能为空哦。')
 return redirect('/')
 elif c2.exists():
 messages.error(request, '对不起，您不能再次借阅该图书了。')
 return redirect('/')
 elif c3 == 5:
 messages.error(request, '对不起，您将超出图书馆借阅图书数量限制。')
 return redirect('/')
 else:
 if bookinfo.exists():
 return render(request, "systeam/searched.html",
 {'bookinfo': bookinfo, 'username': username, 'is_staff': is_staff})
 else:
 messages.error(request, '亲，没有这本书呢。')
 return redirect('/')
 else:
 return render(request, "systeam/searched.html", {'username': username})

3. 把messages渲染到页面中

{% if messages %}

 <ul class="messages">

 {% for message in messages %}


 <li{%if message.tags %} class="{{ message.tags }}"{% endif %}>
 <div class="m_title">
 {{ message.tags }}
 <a href="" id=" rel="external nofollow" rel="external nofollow" a_tuichu">
 <i class="iconfont icon-fork"></i>
 </a>
 </div>
 <div id="m_box">
 {{ message }}
 </div>
 <a href="" id=" rel="external nofollow" rel="external nofollow" a_sure">
 <button id="button_sure">
 确认
 </button>
 </a>
 </li>

 {% endfor %}

 </ul>

 {% endif %}
