Django-import-export 总是导入空值

Question

问候我在 Django 3 中使用 Django-import-export，我试图导入一个 csv 文件，但它总是导入，就像文件中没有数据一样。

我已经按照教程进行操作，并在资源配置中尝试了不同的方法，但是没有任何效果，它总是像这样上传所有数据为空：

这是我的模型：

class Product (Master):

    internal_id = models.IntegerField(verbose_name=_("internal id"), default=0)
    year = models.IntegerField(verbose_name=_("model year"), default=0)
    engine = models.CharField(verbose_name=_("engine type"), max_length=100, null=True, blank=True)
    fuel = models.CharField(verbose_name=_("fuel type"), max_length=100,null=True, blank=True)
    gearbox = models.CharField(verbose_name=_("gearbox type"), max_length=100, null=True, blank=True)
    traction = models.CharField(verbose_name=_("traction"), max_length=100, null=True, blank=True)
    color = models.CharField(verbose_name=_("Color"), max_length=100, null=True, blank=True)
    doors = models.IntegerField(verbose_name=_("doors number"), default=4, null=True, blank=True)
    seats = models.IntegerField(verbose_name=_("seats number"), default=5, null=True, blank=True)
    length = models.FloatField(verbose_name=_("length"), default=0, null=True, blank=True)
    height = models.FloatField(verbose_name=_("height"), default=0, null=True, blank=True)
    wide = models.FloatField(verbose_name=_("wide"), default=0, null=True, blank=True)
    mileage = models.FloatField(verbose_name=_("mileage"),default=0, null=True, blank=True)

    cylinders = models.IntegerField(verbose_name=_("cylinders"),default=0, null=True, blank=True)
    brand = models.CharField(verbose_name=_("brand"), max_length=100, null=True, blank=True)

    price = models.BigIntegerField(verbose_name=_("price"), default=0, null=True, blank=True)
    category = models.ForeignKey('products.Category', on_delete=models.CASCADE, blank=True, null=True, verbose_name=_("category"))

    url=models.SlugField(max_length=100, verbose_name=_("url"))


    class Meta:
        ordering = ["internal_id", "name", "updated"]
        verbose_name = _("product")
        verbose_name_plural = _("products")

    def save(self, *args, **kwargs):
        url=str(self.internal_id)+str(random.randrange(0,1000))+"-"+str(self.name)
        self.url = slugify(url)
        super(Product, self).save(*args, **kwargs)

这是我的资源：

class ProductResource(resources.ModelResource):

    class Meta:
        model = Product
        fields = ['id', 'internal_id', 'category', 'brand', 'name', 'year', 'fuel', 'color', 'gearbox', 'traction', 'cylinders', 'mileage', 'price']

这是我的管理员：

@admin.register(Product)
class ProductsAdmin(ImportExportModelAdmin):
    resource_class = ProductResource
    list_display = ('id', 'internal_id', 'name', 'active', 'url', 'created', 'updated')
    fieldsets = [
                    (_('main details'),         {'fields': ['internal_id','name','year','brand','price','engine','gearbox','category']}),
                    (_('secondary details'),    {'fields': ['fuel','traction','mileage','cylinders','seats','doors','color','description']}),
                    (_('dimensions'),           {'fields': ['height', 'length', 'wide']}),
                    (_('others'),               {'fields': ['url','active'],'classes': ['collapse', 'extrapretty']}),
                ]

    inlines = [ProductImageInline]

这是我的数据

是不是我做错了什么？非常感谢您的帮助

Answer 1

我建议通过管理员向产品添加一些数据。之后尝试将它们导出到 csv 文件，然后从 csv 文件导入数据。 P.S。我想 csv 文件中的每一列都必须有一个 header.

祝一切顺利。
