Python 如何在Django中向sqlite数据库添加值

我有一个Django模型，如下所示：

from django.db import models

class Vehicle(models.Model):
    reference = models.CharField(max_length=100, blank=False, null=False)
    make = models.CharField(max_length=100, blank=False, null=False)
    model = models.CharField(max_length=100, blank=False, null=False)

def get_vehicles():
    try:
        fetched_vehicles = [.....]
        for vehicle in fetched_vehicles:
            n_vehicle = Vehicle()
            n_vehicle.reference = "123456",
            n_vehicle.make = "SKODA",
            n_vehicle.model = "Octavia SW",
            n_vehicle.save()


        return "Success"
    except Exception as e:
        print(str(e))

我想向

db.sqlite3

文件添加一些数据

我有如下简单的功能：

from django.db import models

class Vehicle(models.Model):
    reference = models.CharField(max_length=100, blank=False, null=False)
    make = models.CharField(max_length=100, blank=False, null=False)
    model = models.CharField(max_length=100, blank=False, null=False)

def get_vehicles():
    try:
        fetched_vehicles = [.....]
        for vehicle in fetched_vehicles:
            n_vehicle = Vehicle()
            n_vehicle.reference = "123456",
            n_vehicle.make = "SKODA",
            n_vehicle.model = "Octavia SW",
            n_vehicle.save()


        return "Success"
    except Exception as e:
        print(str(e))

当我在数据库中执行此函数时，我看到的是元组，而不是照片上的值：

---

有什么想法吗？

这是因为您添加了尾随逗号（将值包装在单元组中）。你应该写

.reference=“123456”

这样，结尾不带逗号。@WillemVanOnsem这么愚蠢的fout。谢谢。这是因为您添加了尾随逗号（将值包装在单元组中）。你应该写
