我正在尝试使用django-adaptors导入 csv 文件,不幸的是我在此过程中遇到了错误。
我像这样创建了我的模型和 CSV 类:
class depts(models.Model):
iddepts = models.AutoField(primary_key=True)
CustomerID = models.IntegerField(default=0, null=False)
CustomerName = models.CharField(max_length=750, default='none', null=False)
InvoiceID = models.IntegerField(max_length=20, default=0, null=False)
Currency = models.CharField(max_length=3, default='EUR', null=False)
CurrencyRate = models.DecimalField(max_digits=5, decimal_places=2)
PriceWithoutVAT = models.DecimalField(max_digits=20, decimal_places=2)
PriceWithVAT = models.DecimalField(max_digits=20, decimal_places=2)
VAT = models.DecimalField(max_digits=20, decimal_places=2)
CustomerVATID = models.CharField(max_length=35, default='000-000-000-000', null=False)
CustomerAddress = models.CharField(max_length=750, default='none', null=False)
InvoiceBranch = models.IntegerField(max_length=3, default='000', null=False)
InvoiceVATType = models.IntegerField(max_length=1, default='1', null=False)
InvoiceDateCreate = models.DateField(auto_now=True)
InvoiceDateDue = models.DateField(auto_now=True)
InvoiceCodeVAT = models.CharField(max_length=20, default='none', null=False)
PriceWithoutVATStandard = models.DecimalField(max_digits=20, decimal_places=2)
PriceWithVATStandard = models.DecimalField(max_digits=20, decimal_places=2)
VATStandard = models.DecimalField(max_digits=20, decimal_places=2)
AccountVAT = models.CharField(max_length=20, default='none', null=False)
AccountPriceWithoutVAT = models.CharField(max_length=20, default='none', null=False)
AccountPriceWithVAT = models.CharField(max_length=20, default='none', null=False)
class Meta:
verbose_name = "Invoice"
verbose_name_plural = "Invoices"
def __str__(self):
return self.InvoiceID
def __unicode__(self):
return self.InvoiceID
class MyCsvModel(CsvDbModel):
class Meta:
dbModel = depts
delimiter = ";"
has_header = True
我的 csv 文件如下所示:
CustomerID;CustomerName;InvoiceID;Currency;CurrencyRate;PriceWithoutVAT;PriceWithVAT;VAT;CustomerVATID;CustomerAddress;InvoiceBranch;InvoiceVATType;InvoiceDateCreate;InvoiceDateDue;InvoiceCodeVAT;PriceWithoutVATStandard;PriceWithVATStandard;VATStandard;AccountVAT;AccountPriceWithoutVAT;AccountPriceWithVAT
73269;Good CO;131002919;EUR;1;141.12;173.58;32.46;666-666-11-11;Good street 123;002;1;2013-04-15;2013-04-22;21% ;141.12;173.58;32.46;111-111;111-111-111;111-111-11111
您可以看到我有额外的字段 im 模型“iddepts”,它是主键,在 MyCsvModel 剂量 slove 问题中排除它。我在 import_data 上仍然有错误。
>>>from app.models import MyCsvModel
>>>my_csv_list = MyCsvModel.import_data(data = open("file.csv"))
Traceback (most recent call last):

提前致谢。
