导出后端配置

序列化器配置

定义一个用于导出的序列化器

class ExportUserProfileSerializer(CustomModelSerializer):
    """
    用户导出 序列化器
    """
    last_login = serializers.DateTimeField(format="%Y-%m-%d %H:%M:%S", required=False, read_only=True)
    dept__deptName = serializers.CharField(source='dept.deptName', default='')
    dept__owner = serializers.CharField(source='dept.owner', default='')
    gender = serializers.CharField(source='get_gender_display',read_only=True)

    class Meta:
        model = Users
        fields = ( 'username', 'name', 'email', 'mobile', 'gender', 'is_active', 'last_login', 'dept__deptName',
                  'dept__owner')

视图配置

1.export_field_label 是Excel表的表头,为一个list字段,与序列化中的 fields 对应起来.

2.export_serializer_class 使用导出序列化器

class UserViewSet(CustomModelViewSet):
    """
    用户接口
    list:查询
    create:新增
    update:修改
    retrieve:单例
    destroy:删除
    """
    queryset = Users.objects.exclude(is_superuser=1).all()
    serializer_class = UserSerializer
    create_serializer_class = UserCreateSerializer
    update_serializer_class = UserUpdateSerializer
    filter_fields = ['name','username','gender','is_active','dept']
    search_fields = ['username','name','gender','dept__name','role__name']
    #导出
    export_field_label = ['用户账号', '用户名称','用户邮箱', '手机号码', '用户性别', '帐号状态', '最后登录时间', '部门名称', '部门负责人']
    export_serializer_class = ExportUserProfileSerializer
#接口配置
re_path('user/export/', UserViewSet.as_view({'get': 'export_data', })),

api.js

import { request,downloadFile } from '@/api/service'

...
/**
 * 导出
 * @param params
 */
export function exportData (params) {
  return downloadFile({
    url:urlPrefix+'export/',
    params:params
  })
}

导入配置

导入后端配置

序列化器配置

1.run_validation函数用于对数据进行格式转换

class UserProfileImportSerializer(CustomModelSerializer):

    def save(self, **kwargs):
        data = super().save(**kwargs)
        password = hashlib.new('md5', self.initial_data.get('password', '').encode(encoding='UTF-8')).hexdigest()
        data.set_password(password)
        data.save()
        return data

    def run_validation(self, data={}):
        # 把excel 数据进行格式转换
        if type(data) is dict:
            data['role'] = str(data['role']).split(',')
            data['dept_id'] = str(data['dept']).split(',')
            data['gender'] = {'男': '1', '女': '0', '未知': '2'}.get(data['gender'])
            data['is_active'] = {'启用': True, '禁用': False}.get(data['is_active'])
        return super().run_validation(data)

    class Meta:
        model = Users
        exclude = ('password','post','user_permissions', 'groups', 'is_superuser', 'date_joined')

视图配置

1.import_serializer_class为使用的导入序列化器

2.import_field_dict为字典格式,key为数据库的model字段,value为Excel表的表头列

class UserViewSet(CustomModelViewSet):
    """
    用户接口
    list:查询
    create:新增
    update:修改
    retrieve:单例
    destroy:删除
    """
    queryset = Users.objects.exclude(is_superuser=1).all()
    serializer_class = UserSerializer
    create_serializer_class = UserCreateSerializer
    update_serializer_class = UserUpdateSerializer
    filter_fields = ['name','username','gender','is_active','dept']
    search_fields = ['username','name','gender','dept__name','role__name']
    #导出
    export_field_label = ['用户账号', '用户名称','用户邮箱', '手机号码', '用户性别', '帐号状态', '最后登录时间', '部门名称', '部门负责人']
    export_serializer_class = ExportUserProfileSerializer
    #导入
    import_serializer_class = UserProfileImportSerializer
    import_field_dict = {'username': '登录账号', 'name': '用户名称', 'email': '用户邮箱', 'mobile': '手机号码',
                         'gender': '用户性别(男/女/未知)',
                         'is_active': '帐号状态(启用/禁用)', 'password': '登录密码', 'dept': '部门ID', 'role': '角色ID'}
#接口配置
 re_path('user/import/',UserViewSet.as_view({'get': 'import_data', 'post': 'import_data'})),

导入导出前端配置

index.vue

<template>
  <d2-container :class="{ 'page-compact': crud.pageOptions.compact }">
    <d2-crud-x
      ref="d2Crud"
      v-bind="_crudProps"
      v-on="_crudListeners"
    >
      <div slot="header">
        <crud-search

          :options="crud.searchOptions"
          @submit="handleSearch"

            @click="addRow"
          ><i class="el-icon-plus"/> 新增
          </el-button>
          <el-button

        <crud-toolbar
          :search.sync="crud.searchOptions.show"

          :columns="crud.columns"
          @refresh="doRefresh()"
          @columns-filter-changed="handleColumnsFilterChanged"
        />
      </div>
    </d2-crud-x>
  </d2-container>
</template>

script

...
methods: {
    getCrudOptions () {
      return crudOptions(this)
    },
    pageRequest (query) {
      return api.GetList(query)
    },
    addRequest (row) {
      return api.createObj(row)
    },
    updateRequest (row) {
      return api.UpdateObj(row)
    },
    delRequest (row) {
      return api.DelObj(row.id)
    },
    onExport () {
      this.$confirm('是否确认导出所有数据项?', '警告', {
        confirmButtonText: '确定',
        cancelButtonText: '取消',
        type: 'warning'
      }).then(function () {
        return api.exportData()
      })
    }
  }
 ...

添加初始化菜单

"menu_button": [
    ...
    {
        "name": "导出",
        "value": "Export",
        "api": "/api/walking/activity/users_bind_enterprise/export/",
        "method": 0
    },
    {
        "name": "导入",
        "value": "Import",
        "api": "/api/walking/activity/users_bind_enterprise/import/",
        "method": 0
    }
    ...
]
