如何在 django-import/export 上导入 auth.User

Question

我无法将 CSV 文件导入到 Django 上的模型中。我创建了一个列 'author' 并将我登录到管理站点的超级用户的 ID 放入。但是导入CSV文件的时候出现了这样的错误

Line number: 1 - null value in column "author_id" violates not-null constraint DETAIL: Failing row contains (10, abc, blahblah, null, ).
5, abc, blahblah, , nah,wha,blah

csv 文件

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

models.py

from django.db import models
from django.urls import reverse
from taggit.managers import TaggableManager

class KnowHow(models.Model):    

    author = models.ForeignKey('auth.User',on_delete=models.CASCADE)
    title = models.CharField(max_length=200)
    text = models.TextField(blank=True)
    file = models.FileField(blank=True,upload_to='explicit_knowhows')
    free_tags = TaggableManager(blank=True)

    def __str__(self):
        return self.title

admin.py

from django.contrib import admin
from import_export import resources
from import_export import fields
from import_export.admin import ImportExportModelAdmin

from .models import KnowHow
# Register your models here.

class KnowHowResource(resources.ModelResource):

    class Meta:
        model = KnowHow
        exclude = 'id'
        import_id_fields = ('title', )

@admin.register(KnowHow)
class knowHowAdmin(ImportExportModelAdmin):
    resource_class = KnowHowResource

Answer 1

错误说 author_id 被遗漏了。

Django adds a postfix 到所有 ForeignKey 字段，所以你应该尝试修改文件重命名列：

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

Answer 2

当我通过 UTF-8 编码保存 CSV 时，它已修复。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的问题的人。
