使用OneToOneField时，django-import-export键错误

Question

我的models.py文件是

from django.db import models

class companyDetail(models.Model):
    short_code = models.CharField(primary_key=True, max_length=50)
    title = models.CharField(max_length=50)
    page_title = models.CharField(max_length=50)

    class Meta:
        verbose_name = "companyDetail"
        verbose_name_plural = "companyDetails"

    def __str__(self):
        return self.title

class companyDescription(models.Model):
    comDetail = models.OneToOneField(
        companyDetail,
        on_delete=models.CASCADE,
        related_name='coDetail',
        primary_key=True,
        )
    description = models.CharField(max_length=5000)
    add_description = models.CharField(max_length=5000)

    class Meta:
        verbose_name = "companyDescription"
        verbose_name_plural = "companyDescriptions"

    def __str__(self):
        return self.comDetail.title

我试图将我的模型/表格"company“分解成两个不同的模型"companyDetail”和"companyDescription“，并通过OneToOneField将它们连接起来。

当我试图通过shell添加数据时，它工作得很好。

我正在为模型"companyDetail“导入csv到django-import-export它工作正常，但是我正在为模型"companyDescription”导入csv，它抛出错误：

Traceback (most recent call last):
File "/home/abhirajput/testpro/myenv/lib/python3.5/site-packages/import_export/resources.py", line 453, in import_row
instance, new = self.get_or_init_instance(instance_loader, row)
File "/home/abhirajput/testpro/myenv/lib/python3.5/site-packages/import_export/resources.py", line 267, in get_or_init_instance
instance = self.get_instance(instance_loader, row)
File "/home/abhirajput/testpro/myenv/lib/python3.5/site-packages/import_export/resources.py", line 261, in get_instance
return instance_loader.get_instance(row)
File "/home/abhirajput/testpro/myenv/lib/python3.5/site-packages/import_export/instance_loaders.py", line 31, in get_instance
field = self.resource.fields[key]
KeyError: 'comdetail'

请帮助我在外行方面，因为我是一个土木工程师试图进入网络开发和打破表格(绝命毒师)。如果您对将模型/表格"company“分解为两个模型"companyDetail”和"companyDescription“有任何其他建议，请告诉我。

提前感谢

Answer 1

有一个打字错误：

KeyError: 'comdetail'

related_name='coDetail',

Answer 2

我知道这有点太晚了。你需要在你的应用中创建一个资源文件。

​

class companyDescriptionResource(resources.ModelResource):
        class Meta:
        model = companyDescription
        import_id_fields = ['comDetail']
