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“ company”分为两个不同的模型“ companyDetail”和“ companyDescription”,并通过OneToOneField将它们连接起来。
当我尝试通过外壳添加数据时,它工作正常。
我将cv导入django-import-export用于模型“ companyDetail”,它工作正常,但是我将cv导入到模型“ companyDescription”,它将引发错误:
Traceback (most recent call last):

请以通俗易懂的方式为我提供帮助,因为我是一名土木工程师,正致力于进入Web开发并打破常规(Breaking Bad)。
如果您对将模型/表“ company”分为两个模型“ companyDetail”和“ companyDescription”还有其他建议,请告诉我。
提前致谢
最佳答案
有一个错字:
KeyError: 'comdetail'
related_name='coDetail',
关于python - 使用OneToOneField时django-import-export键错误,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/52537446/
