1 用户模块管理分析

1.1 管理模块部分功能展示

技术图片

1.2 前端总体业务逻辑分析

  • Vue组件思想

vue本身就是一个组件,所以我们在使用的过程中,一定要有组件思想。本项目就是利用父子组件传值,调用方法来进行编写的。

1.2.1 Home页面
  • 其中嵌套组件Header和LeftMenu

总页面,主要用于布局。用于显示左侧菜单和头部信息。其中嵌套子路由用于不同模块之间的跳转。

技术图片

  • Header用于头部信息展示

技术图片

  • LeftMenu用于左侧菜单展示

技术图片

  • 模块跳转部分嵌套子路由

技术图片

1.2.2 Index页面
  • 嵌套四个组件

BreadCrumb,EditForm,Search,TableList,用于模块之间的跳转变化。

  • BreadCrumb用于顶部路径展示

技术图片

  • EditForm用于控制输入框信息,修改和添加时有所不同
    • 修改(在原有数据基础上进行修改,并且不支持密码和用户名的修改)

技术图片

    • 添加

技术图片

  • Search控制查找

技术图片

  • TableList控制表格展示,会随着Search输入的查找数据变化

1.3 后端总体业务逻辑分析

1.3.1 ModelViewSet
  • 用于用户信息管理的增删改查
  • 注意事项:
* 查询接口
http://192.168.56.100:1594/user/user/?username=‘cat‘
* 添加接口
http://192.168.56.100:1594/user/user/
* 删除接口(指定用户id删除)
http://192.168.56.100:1594/user/user/id/
* 修改接口(指定用户id修改)
http://192.168.56.100:1594/user/user/id/
1.3.2 APIView
  • 用于注册用户的业务逻辑

4 总结点

4.1 serializer重写

class UserSerializer(serializers.Serializer):
    # 用serializer重写,不能用ModelViewSet来添加,写上id会报错username不能设为key,因为User表继承的是AbstractUser,其中的username字段必须有unique=True属性设置唯一约束
    username = serializers.CharField()
    password = serializers.CharField()
    mobile = serializers.CharField()
    email = serializers.EmailField()
    token = serializers.CharField(read_only=True)

    def create(self, data):
        username = data.get(‘username‘, ‘‘)
        password = data.get(‘password‘, ‘‘)
        mobile = data.get(‘mobile‘, ‘‘)
        email = data.get(‘email‘, ‘‘)
        user = User(username=username, email=email, mobile=mobile)
        user.set_password(password)
        user.save()
        # 补充生成记录登录状态的token
        jwt_payload_handler = api_settings.JWT_PAYLOAD_HANDLER
        jwt_encode_handler = api_settings.JWT_ENCODE_HANDLER
        payload = jwt_payload_handler(user)
        token = jwt_encode_handler(payload)
        user.token = token
        return user

	def update(self, instance, validated_data):
        # instance 是当前对象obj
        # validated_data 是获取的变量
		instance.mobile = validated_data.get(‘mobile‘)
		instance.email = validated_data.get(‘email‘)
		instance.save()
		return instance

4.2 要注意ModelViewSet的接口路由

  • 后端接口
* 查询接口
http://192.168.56.100:1594/user/user/
http://192.168.56.100:1594/user/user/?username=‘cat‘
* 添加接口
http://192.168.56.100:1594/user/user/
* 删除接口(指定用户id删除)
http://192.168.56.100:1594/user/user/id/
* 修改接口(指定用户id修改)
http://192.168.56.100:1594/user/user/id/
  • 前端访问路径配置
export const get_userlist = P => axios_get(‘/user/user/‘, P)     
// 查询所有:获取用户列表
export const search_for = P => axios_get(‘user/user/?username=‘ + P.username)   
// 查找指定信息:根据用户名查找指定用户信息并展示
export const add_user = P => axios_post(‘/user/user/‘, P)     
// 添加用户信息
export const delete_user = P => axios_delete(‘/user/user/‘ + P + ‘/‘)           
// 删除指定信息:根据获取到的用户id删除用户信息
export const update_user = P => axios_put(‘/user/user/‘+ P.id +‘/‘, P)    
// 修改指定信息:根绝用户id和提交来的数据修改用户信息

4.3 使用 ant-design-vue

// 使用ant-design-vue
import Antd from ‘ant-design-vue‘;
import ‘ant-design-vue/dist/antd.css‘;
Vue.config.productionTip = false
Vue.use(Antd);

4.4 ModelViewSet修改问题

  • put请求默认是全部修改
  • patch请求可以实现局部修改(后端已经封装好了方法)

4.5 Vue嵌套路由

  • index.js
import Vue from ‘vue‘
import Router from ‘vue-router‘
import Home from ‘@/components/layout/Home‘
// 用于导包路径的配置
const page = name => () => import(‘@/views/‘ + name)
Vue.use(Router)

export default new Router({
  mode: ‘history‘,
  routes: [
    // 用户管理模块
    { path: ‘/‘,component: Home,name: ‘home‘,
      children: [
        { path: ‘usermanage‘, component: page(‘user-manage/Index‘), name: ‘用户管理‘ },
        { path: ‘flowconf‘, component: page(‘workflow/WorkFlowConf‘), name: ‘模板管理‘ },
        { path: ‘flowtype‘, component: page(‘workflow/WorkFlowType‘), name: ‘模板类型管理‘ },
        { path: ‘baidu‘, component: page(‘BaiDu‘), name: ‘跳转百度‘ },
      
      ]
    },
  ]
})
  • Home页面中写入
<template>
    <div id="components-layout-demo-basic">
         <a-layout>
              </a-layout-header>
                  <div>
                     <!-- 这里的 router-view 是绑定的路由 -->
                     <router-view></router-view>
                   </div>
              </a-layout-header>
          </a-layout>
    </div>
</template>

<script>
// 导入组件
import LeftMenu from ‘@/components/layout/LeftMenu‘
import Header from ‘@/components/layout/Header‘
export default {
    // 注册组件
    components:{
        LeftMenu,
        Header
    },
}
  • 绑定左侧菜单LeftMenu
<template>
  <div>
    <a-menu
      style="width: 256px"
      :default-selected-keys="[‘1‘]"
      :default-open-keys="[‘sub1‘]"
      :mode="mode"
      :theme="theme"
      @click="handleClick"
    >
    <!-- 必须定义click方法,handleClick是用来跳转路由的,内置毁掉参数e,包括传递上去的key路由地址 -->    
      <a-menu-item key="usermanage">
        <!-- key是路由地址 -->
        用户管理模块
      </a-menu-item>

      <a-menu-item key="baidu">
        百度翻译
      </a-menu-item>
    </a-menu>
  </div>
</template>
<script>
export default {
  data() {
    return {
    };
  },
  methods: {
     handleClick(e) {
      this.current = e.key;
      this.$router.push({path:this.current});
      // click方法默认回调参数中的 key,所以 e.key就是传递来的路由
    },
  },
};
</script>

4.6 ant-design-vue 图标大小

  • font-size 可以调节图标大小

4.7 v-if v-else控制input框disabled属性

<template>
    <div>
        <a-modal
        title="Please write now."
        :visible="visible"
        @ok="handleOk"
        @cancel="handleCancel"
        >
        <!-- @ok控制按钮ok -->
        <!-- @cancel控制按钮cancel -->
            <p v-if="userList.id">UserName:
                <a-input 
                style="width:380px;float:right" 
                placeholder="username" 
                v-model="userList.username"
                disabled="disabled"
                ></a-input>    
                <!-- disabled可以用来控制input是否能输入文字 -->
            </p>
            <p v-else>UserName:
                <a-input 
                style="width:380px;float:right" 
                placeholder="username" 
                v-model="userList.username"
                ></a-input>
            </p>
            <br>
            
            <div v-if="userList.id">

            </div>
            
            <div v-else>
            <p>PassWord:
                <a-input
                    v-decorator="[
                        ‘password‘,
                        { rules: [{ required: true, message: ‘Please input your Password!‘ }] },
                    ]"
                    type="password"
                    placeholder="Password"
                    style="width:380px;float:right"
                    v-model="userList.password"
                    :disabled = ‘false‘
                >
                </a-input>
            </p>
        </a-modal>
    </div>
</template>

<script>
export default {
    props:[‘visible‘, ‘userList‘],
    methods: {
        handleOk(e) {
            this.$emit(‘add‘)
            // add方法的调用一定要在关闭弹窗上面,否则方法不执行完毕没有办法关闭弹窗        
            this.$emit(‘update:visible‘, false)
        },
        handleCancel(e) {
            this.$emit(‘update:visible‘, false)
        },
    },
}
</script>

4.8 a-table中的分页器&按钮

 <a-table 
    :columns="要展示的列名称(可以自定义列表)" 
    :data-source="要展示的动态数据表名" 
    :pagination="pagination" 
    :rowKey="(record,index)=>{return index}"
  >
  <!-- 带:的都是属性绑定,不可以更换名字,带 : 就是 js 环境 -->
  <!-- 不写:rowKey="(record,index)=>{return index}"浏览器会发出警告 -->
     <p slot="tags" slot-scope="text,tags,i">
      <!-- 加入操作的按钮!其中tags是某列数据,i是索引 -->
      <a-button @click="delUser(text,tags,i)">删除</a-button>
    </p>
  </a-table>

4.9 a-table中获取某一行值的方法

<template>
  <a-table 
    :columns="columns" 
    :data-source="userListGet" 
    :pagination="pagination" 
    :rowKey="(record,index)=>{return index}"
  >
  <!-- 带:的都是属性绑定,不可以更换名字,带 : 就是 js 环境 -->
    <!-- 不写:rowKey="(record,index)=>{return index}"浏览器会发出警告 -->
    <p slot="tags" slot-scope="text,tags,i">
      <!-- 加入操作的按钮! -->
      <a-button @click="delUser(text,tags,i)">删除</a-button>
    </p>
  </a-table>
</template>

<script>
const columns = [
  {
    title:‘操作‘,
    dataIndex: ‘tags‘,
    key : ‘tags‘,
    width: 100,
    scopedSlots : { customRender: ‘tags‘}
    // scopedSlots: { customRender: ‘tags‘ },一定不能少不然渲染不了html标签
  }
]

import { delete_user } from ‘@/http/apis‘
export default {
  data() {
    return {
      columns,//这里要返回值哦 
      pagination:{
      pageSize: 4,
      }
    };
  },
  methods:{
    delUser(text,tags,i){
       }     
    },
  }
</script>

4.10 控制对话框

// 定义变量 isDel来控制 confirm,isDel==true执行的就是对话框的 ok,isDel==false执行的就是对话框的 false
const isDel = confirm(‘你确定要删除‘ + tags.id)
if(isDel==true){
	delete_user(tags.id).then(
		res=>{
		// 删除回调地址是  http://192.168.56.100:1594/id/
		this.get()
			alert(‘删除成功啦~‘)
		})
}else{
	alert(‘有需要再叫我哈~‘) 
}

4.11 自动跳转到某一网址

window.location.href = ‘https://www.baidu.com/‘

4.12 前后端联调分页

  • 为了解决前端+后端能同时进行分页的问题,只定义前端分页,后端如果分页就会影响前端数据,如果后端不定义分页器,就会造成后端admin难以管理。

  • 后端代码

    • 实现局部分页
    from django.shortcuts import render
    from rest_framework import viewsets
