Question

我想将数据导入到多个字段。

下面我的代码导入了数据，但只对模型应用了一个关系（不是两个，因为我在下面要求它执行两次 - 我写“cat = ...”）

在下面的示例中，我希望它从第4列和第4列导入cat（类别）。 11.我的下面的代码只对模型应用了一个类别（而不是两个）。

如何将两个字段应用于模型？我正在使用python 2.7

import csv

l = list(csv.reader(open('test_data.csv', 'rb')))

Gender_CHOICES = {
    'Male': 1,
    'Female': 2,
    'Unisex': 3,
}

Stock_CHOICES = {
    'in stock': 1,
    'low stock': 2,
    'out of stock': 3,
    'discountinued': 4
}

for i in l[1:]:
        cat = m.Category.objects.get_or_create(category_name = i[4],[11])[0]
        prod = m.Product(
            name = i[0],
            link = i[1],
            description = i[6],
            brand = i[7],
            colour = i[10],
            gender = Gender_CHOICES[i[8]] if i[8] in Gender_CHOICES else 3,
            store = m.Store.objects.get_or_create(store_name = i[2])[0]
            )
        prod.save()
        var = m.Variation(
            product = prod,
            variation = "default"
            )
        var.save()
        img = m.Image(
            variation = var,
            image = i[5]
            )
        img.save()
        size = m.Size(
            variation = var
            )
        size.save()
        price = m.Price(
            variation = var,
            price = float(i[3])
            )
        price.save()
        stock = m.Stock(
            size = size,
            stock = Stock_CHOICES[i[9]] if i[9] in Stock_CHOICES else 4
            )
        stock.save()
        prod.category.add(cat)

CSV示例：

Answer 1

我相信，问题在于对象创建。我认为您正在寻找以下内容：

....
....
for i in l[1:]:
        cat_1 = m.Category.objects.get_or_create(category_name = i[4])
        cat_2 = m.Category.objects.get_or_create(category_name = i[11])
....
....
prod.category.add(cat_1)
prod.category.add(cat_2)

导入多对多关系（Django）
