错误表示缺少
作者id

Django指向所有
ForeignKey
字段,因此您应该尝试修改重命名列的文件:

author_id,title,text,file,free_tags
5,abc,blahblah,,"nah,wha,blah"

当我用UTF-8编码保存CSV时,它被修复了。这将不支持非字母字母,因此我建议改用.xlsx文件。
感谢所有试图解决我问题的人。

也许可以在文档中添加,以改进答案。我这样做了,但不幸的是,没有任何更改。
作者id、类别、标题、文本、文件、基本标签、免费标签5、abc、blahblah、、“不,cmon,等等”
是的<代码>行号:1-列“author_id”中的null值违反了非null约束详细信息我还尝试将“author”列的值添加到用户名,但也没有更改。我还注意到我无法导入Django taggit。我会问另一个问题。
