将queryset传递给导出方法：

queryset = Price.objects.exclude(...)
data = ExportData().export(queryset)
data.csv

要仅过滤导出的文件，而不是管理屏幕中的实际列表，您可以覆盖get_export_queryset方法

from import_export import resources
from import_export.admin import ImportExportMixin

class ProductAdmin(ImportExportMixin, admin.ModelAdmin):
    resource_class = ProductResource

    # Override of ImportExportMixin.get_export_queryset
    # Filter export to exclude Products where is_active is false
    def get_export_queryset(self, request):
            return Product.objects.filter(is_active=True)

您可以在admin.py文件中覆盖resources.ModelResource的export方法，以在admin上应用筛选器：

from import_export import resources
from finance.models import Price

class ExportData(resources.ModelResource):

    class Meta:
        model = Price

    def export(self, queryset=None, *args, **kwargs):
        # For example only export objects with ids in 1, 2, 3 and 4
        queryset = queryset and queryset.filter(id__in=[1, 2, 3, 4])
        return super(ExportData, self).export(queryset, *args, **kwargs)

您可以只修改ModelResource类的一个导出方法。

from import_export import resources
from finance.models import Price

class ExportData(resources.ModelResource):

    class Meta:
        model = Price
    
    def export(self, queryset = None, *args, **kwargs):
        queryset = queryset.exclude(id = 5)
        return super().export(queryset, *args, **kwargs)
