尝试将 XLSX 文件中的两张工作表中的数据导入两个不同的模型 - 无法引导数据。我正在使用 pyexcel 包来导入 xlsx 数据。我正在关注http://django.pyexcel.org/en/latest/
注意：我试图从单张单模型加载数据。这已成功加载，没有任何问题。
但是，将两个工作表数据导入两个不同的模型时出现问题（具有外键关系）
使用的型号：
class Supplier(models.Model):
Supplier_Number = models.IntegerField(unique=True)
Supplier_Name = models.CharField(max_length=150)
Supplier_Contracting_Entity = models.CharField(max_length=150)
Applicable_Brands = models.CharField(max_length=150)
Currency_To_Be_Paid = models.CharField(max_length=3)
Other_Remarks = models.CharField(max_length=150)
Term = models.CharField(max_length=15)
Notes = models.CharField(max_length=150)
Fee_Calculation_Basis = models.CharField(max_length=25)
def __str__(self):
return self.Supplier_Name
class Tax_Vat(models.Model):
Supplier = models.ForeignKey(Supplier, on_delete=models.CASCADE)
#Supplier_Number = models.IntegerField()
#-- Above will store the Supplier ID, which is generated automatically
COUNTRY =models.CharField(max_length=25)
DEDUCTION_TYPE =models.CharField(max_length=5)
NGR_FLAG =models.CharField(max_length=5)
TAX_VAT_RATE = models.FloatField()
def __str__(self):
return self.COUNTRY
视图.py：
class UploadFileForm(forms.Form):
file = forms.FileField()
def sup_import(request):
if request.method == "POST":
form = UploadFileForm(request.POST,request.FILES)
def tax_func(row):
q = Supplier.objects.filter(Supplier_Number=row[0])[0]
row[0] = q
return row
#if form.is_valid():
request.FILES['myfile'].save_book_to_database(
models=[Supplier, Tax_Vat],
initializers=[None, tax_func],
mapdicts=[
{ "Supplier_Number": "Supplier_Number",
"Supplier_Name": "Supplier_Name",

}
]
)
return redirect('Royalty_upload.html')
# else:
#return HttpResponseBadRequest()
else:
form = UploadFileForm()
return render(
request,
'Royalty_upload.html',
{
'form': form,

'header': 'Please upload Royalty_Input_Import_Data_All.xlsx:'
})
