django 配置admin 数据管理，增加数据批量上传下载功能

在使用django-admin带来直接管理数据库带来的便利的同时,我们希望数据能批量上传,为了达到此目的,我们需要django-admin-export 模块

一、安装模块

 pip3 install django-import-export -i https://mirrors.aliyun.com/pypi/simple/

二、settings.py注册模块

INSTALLED_APPS = [
    'simpleui',
    'daterange_filter',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    # 'app01',
    'monitor01',
    'import_export'

]

三、准备Module数据表，admin后台注册

modules.py

# Resource 资源列表
class Resource(models.Model):
    name = models.CharField(max_length=256, verbose_name='资源名称')#verbose_name表示admin管理时显示的中文
    uid = models.CharField(max_length=32, verbose_name='账号UID')
    namespace = models.CharField(max_length=32, verbose_name='资源分类(NameSpace)')#verbose_name表示admin管理时显示的中文
    instance_id = models.CharField(max_length=64, verbose_name='实例ID')
    region_select = (
        ("cn-beijing-6", "华北1（北京）"),
        ("cn-shanghai-2", "华东1（上海）"),
        ("cn-hongkong-2", "中国香港"),
        ("cn-guangzhou-1", "华南1（广州）"),
        ("ap-singapore-1", "新加坡"),
        ("eu-east-1", "俄罗斯（莫斯科）"),
        ("cn-beijing-fin", "华北金融1（北京）专区"),
        ("eu-east-1", "华东金融1（上海）专区"),
        ("cn-southwest-1", "西南1(重庆)"),
        ("cn-central-1", "华中1(武汉)"),
        ("cn-northwest-1", "西北1区（庆阳）"),
    )
    '''
    https://docs.ksyun.com/documents/6477
    '''
    region = models.CharField(max_length=32, choices=region_select, verbose_name='所在地区', blank=False)

    # 关联查询的时候展示的中文名称
    def __str__(self):
        return self.name

    # admin后台项目中文显示设置
    class Meta:
        verbose_name = "客户资源"
        verbose_name_plural = "客户资源"
        db_table = 'monitor01_resource'

admin.py 在admin管理模块中注册

from import_export.admin import ImportExportModelAdmin

from django.contrib import admin
# from django.utils.safestring import mark_safe
from django.utils.html import format_html
# from django.forms.widgets import TextInput
from django.db import models as dbmodels

# Register your models here.
from monitor01 import models
from import_export.admin import ImportExportModelAdmin


# ResourceAdmin 支持批量导入数据的Admin
@admin.register(models.Resource)
class ResourceAdmin(ImportExportModelAdmin):
    list_display = ('region', 'namespace', 'uid', 'name', 'instance_id', )
    search_fields = ('namespace', 'uid', 'name', 'instance_id', 'region')
    list_display_links = ('namespace', 'uid', 'name', 'instance_id', 'region')
    pass
