Question

这是我的模型。py

class RegistrationOTP(models.Model):
    country = models.ForeignKey(Country,on_delete=models.CASCADE, related_name='otp_country', default=1)
    phone_number = models.CharField(max_length=13)#, unique=True, validators=[phone_regex],
    otp = models.PositiveIntegerField()
    created_date = models.DateTimeField(auto_now=True)
    is_verified = models.CharField(choices=YES_OR_NO, default='no', max_length=10)

    def __unicode__(self):
        return '%s : %s'% (self.phone_number, self.otp)

class Country(models.Model):
    name = models.CharField(max_length=20, unique=True)
    phone_code = models.CharField(max_length=20, unique=True)

这是我的admin.py

class RegistrationOTPResource(resources.ModelResource):
    class Meta:
    model = RegistrationOTP
    fields = ('id','phone_number','otp','created_date','is_verified','country')

    def to_representation(self, instance):
    rep = super(RegistrationOTPResource, self).to_representation(instance)
    rep['country'] = instance.country.name
    return rep

class RegistrationOTPAdmin(ExportMixin, admin.ModelAdmin):
    resource_class = RegistrationOTPResource

admin.site.register(RegistrationOTP, RegistrationOTPAdmin)

在我的csv国家/地区字段中显示的是国家/地区ID，而不是国家/地区名称。我如何显示国家名称。

请看一下我的代码
