如何在Django Admin中实现数据备份和恢复策略

pip install django-import-export

INSTALLED_APPS = [
    #...
    'import_export',
]

# 导出文件的格式
EXPORT_FORMATS = {
    'csv': 'import_export.formats.csv',
    'xls': 'import_export.formats.xls',
    'xlsx': 'import_export.formats.xlsx',
}

# 导入/导出过程中是否跳过错误行
SKIP_ADMIN_LOG_ERRORS = True

from import_export import resources
from import_export.admin import ExportMixin
from django.contrib import admin


class YourModelResource(resources.ModelResource):
    class Meta:
        model = YourModel


@admin.register(YourModel)
class YourModelAdmin(ExportMixin, admin.ModelAdmin):
    resource_class = YourModelResource

from import_export import resources
from import_export.admin import ExportMixin
from import_export.admin import ImportMixin
from django.contrib import admin
from django.contrib import messages


class YourModelResource(resources.ModelResource):
    class Meta:
        model = YourModel


@admin.register(YourModel)
class YourModelAdmin(ExportMixin, ImportMixin, admin.ModelAdmin):
    resource_class = YourModelResource

    # 导入数据时调用的函数
    def after_import(self, dataset, result, using_transactions, dry_run, **kwargs):
        if not dry_run:
            messages.success(self.request, '数据导入成功！')
