'instancemethod' 对象没有属性 '__getitem__' [英] 'instancemethod' object has no attribute '__getitem__'

问题描述

我不断收到此错误:

TypeError: 'instancemethod' object has no attribute '__getitem__'

根据我在 django 网站上的特殊观点，我正在玩弄.我不知道为什么，但我感觉这可能与我从模型中检索特定对象的方式有关.

With my particular view on a django site I am playing around with. I have no idea why but I have a feeling it might be related to the way I am retrieving a specific object from a model.

错误出现在这里:

def myview(request):
    if request.method == 'POST':
        tel = request.POST.get['tel_number']
        person = get_object_or_404(Employee,phone_number=tel) # HERE

我有一个带有 phone_number 作为 CharField 的 Employee 模型:

I have an Employee model with phone_number as a CharField as such:

class Employee(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=30)
    phone_number = models.CharField(max_length=10)

request.POST 数据是从一个 android 应用程序发送的.我想要做的就是检索具有特定 phone_number 值的 Employee 对象.

The request.POST data is sent from an android application. All I want to do is to retrieve an Employee object that has a particular phone_number value.

谢谢！

推荐答案

问题出在这一行 tel = request.POST.get['tel_number'].如果您使用 .get，您应该将密钥作为参数传递:

The problem is in this line tel = request.POST.get['tel_number']. If you are using .get you should pass the key as an argument:

tel = request.POST.get('tel_number') # if key is not present by default it will return None

否则你可以这样做:

tel = request.POST['tel_number'] # raise KeyError Exception if key is not present in dict
