django - 如何使用 django-import-export 为字段定义管理员导入格式

Question

我正在尝试使用最近开源的 django-import-export通过管理员导入一些数据，我需要选择自定义日期格式。

它有效，但有问题/更好的方法吗？

admin.py:

from import_export.admin import ImportExportMixin, ImportExportModelAdmin
from import_export import resources

from .models import Enrolment

class EnrolmentResource(resources.ModelResource):

    class Meta:
        model = Enrolment
        fields = ('id','source','firstname','surname','date_of_birth',
                  'bonus','status','tracking_comments')

        widgets = {
                'date_of_birth': {'format': '%d/%m/%Y'},
                }

class EnrolmentAdmin(ImportExportMixin, admin.ModelAdmin):

    def get_resource_class(self):
        if not self.resource_class:
            return EnrolmentResource
        else:
            return self.resource_class

admin.site.register(Enrolment, EnrolmentAdmin)

跟随 this代码示例，你应该这样做:

# ...
class EnrolmentResource(resources.ModelResource):
# ...
class EnrolmentAdmin(ImportExportMixin, admin.ModelAdmin):
    resource_class = EnrolmentResource
# ...
admin.site.register(Enrolment, EnrolmentAdmin)
