我在非常简单的操作中遇到了非常奇怪的问题。models.pyNbProducts(models.Model): brand = models.CharField(max_length=45, blank=True, null=True) name = models.CharField(max_length=45, blank=True, null=True) cluster = models.CharField(max_length=45, blank=True, null=True) target_market = models.CharField(max_length=10, blank=True, null=True) cpu_vendor = models.CharField(max_length=45, blank=True, null=True) base_platform = models.CharField(max_length=45, blank=True, null=True) gpu_list = models.CharField(max_length=45, blank=True, null=True) screen_size = models.CharField(max_length=45, blank=True, null=True) screen_resulution_list = models.CharField(max_length=45, blank=True, null=True) touchscreen = models.CharField(max_length=45, blank=True, null=True)views.py list_Products = NbProducts.objects.\ filter(id__in=products_for_execute).\ values('brand', 'name', 'id')# list_Products:#<QuerySet [{'brand': 'Acer', 'name': 'Aspire R7-372T', 'id': 2713}, #{'brand': 'Acer', 'name': 'Aspire S7-393', 'id': 2716}, #{'brand': 'Acer', 'name': 'Swift SF514-51', 'id': 2743},.... class FProducts(object): def __init__(self, id, brand, name): self.id = str(id), self.brand = str(brand), self.name = str(name) print(self.id, self.brand, self.name) fproducts = list() for i in list(list_Products): fproducts.append(FProducts(id=i['id'], brand=i['brand'], name=i['name']))>> {'2713',) ('Acer',) 'Aspire R7-372T'>> {'2716',) ('Acer',) 'Aspire S7-393'>> {'2743',) ('Acer',) 'Swift SF514-51'所以。没有任何命令,它会将两个参数 - 'id' 和 'brand' 放入元组中。参数“名称” - 好吧,只是字符串。我不t need Tuple. And I don明白有什么关系。另外我把这个放进去。 self.id = self.id[0] self.brand = self.brand[0]好的,有帮助,应用程序可以工作。但我看不到问题的根源。这是Python(3.7)还是Django(2.1.7)的问题?

您自己在这里创建了一个元组:
self.id = str(id), self.brand = str(brand), self.name = str(name)
应该:
self.id = str(id) self.brand = str(brand) self.name = str(name)
