Question

我正在使用Django 2.x和Django-import-export在管理面板中启用导入Excel文件。

app / models.py

class ChapterQuestion(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    chapter = models.ForeignKey(Chapter, on_delete=models.CASCADE)
    word = models.CharField(max_length=250)
    definition = models.CharField(max_length=250)
    pronunciation = models.CharField(max_length=250, blank=True)
    synonym = models.CharField(max_length=250, blank=True)
    antonym = models.CharField(max_length=250, blank=True)
    comment = models.CharField(max_length=250, blank=True, null=True)

app / admin.py

class ChapterQuestionResource(resources.ModelResource):
    class Meta:
        model = ChapterQuestion
        fields = (
            'chapter__course__name', 'chapter__name', 'word', 'definition',
            'synonym', 'antonym', 'pronunciation', 'comment'
        )


@admin.register(ChapterQuestion)
class ChapterQuestionAdmin(ImportExportModelAdmin):
    resource_class = ChapterQuestionResource

    exclude = ['created_by']
    list_display = ['word', 'definition', 'chapter', 'get_chapter_course', 'created_by']

但是，当我导入.xls文件时，它显示为（sample file）错误

导入不适用于导出-导入Django
