Django项⽬实战开发之点餐系统第四章员⼯信息管理之分页显⽰+内容搜索
本章内容是针对上⼀章内容进⾏⼀个升级，即加上了⼀个内容搜索功能
1、视图⽂件myadmin/views/myadmin_users.py
from django.shortcuts import render
dels import user
from django.http import HttpResponse
paginator import Paginator
from dels import Q
# Create your views here.
# 加载后台员⼯管理⾸页
def myadmin_users_index(request,Pindex):
try:
ulist = user.objects.filter(status__lt=9)
django项目实例
kw = ('keyword',None)#查询关键字
mywhere =[]
if kw:
ulist = user.objects.filter(Q(username__contains=kw)|Q(nickname__contains=kw))#通过账号或昵称搜索
mywhere.append('keyword='+ kw)
PageUsers = Paginator(ulist,5)#(实例化对象)5个数据分⼀页
Pagenum = PageUsers.num_pages #最⼤页数
PageRange = PageUsers.page_range #页数范围
if Pindex <1:
Pindex =1
elif Pindex > Pagenum:
Pindex = Pagenum
PageContext = PageUsers.page(Pindex)#每页的内容
context ={"users":PageContext,"Pindex":Pindex,"PageRange":PageRange,"kw":mywhere} return render(request,"myadmin/user/myadmin_users_index.html",context)
except Exception as err:
print(err)
return HttpResponse("⽆员⼯数据")
2、模板⽂件templates/user/myadmin_users_index.html
提交搜索form表单，⽤GET⽅法请求
在之前分页跳转超链接基础上再添加请求条件，防⽌冲突
整体代码为以下
{% extends 'myadmin/base.html'%}
{% block main_content %}
<section class="content-header">
