Django import-export 在导出到 csv 时将 manytomany 显示为名称而不是 id

Question

如何使用 Django import-export 将 manytomany 列显示为名称列表而不是 ID？

目前我的模型和 resources.py 看起来像这样 returns 一个带有 country 列的 ID 列表的 csv：

models.py

class Country(models.Model):
    name = models.CharField(max_length=50, null=False,
                            blank=False, unique=True)

    def __str__(self):
        return self.name


class Species(models.Model):
    name = models.CharField(max_length=50, null=False, blank=False)
    country = models.ManyToManyField(Country)

    def __str__(self):
        return self.name

resources.py

from import_export import resources,fields
from import_export.widgets import ManyToManyWidget
from .models import Species, Country

class SpeciesResource(resources.ModelResource):
    country=fields.Field(attribute='country', widget=ManyToManyWidget(Country), column_name='Country')
    name = fields.Field(attribute='name', column_name='Name')
    class Meta:
        model = Species
        fields =('name','country')
        export_order = fields

只需在小部件中添加您需要的字段：

widget=ManyToManyWidget(Country, field='name')
