类在Django中没有“对象”成员 [英] Class has no 'objects' member in django

问题描述

from django.http import HttpResponse
from .models import Destination
def index(request):
    boards = Destination.objects.all()
    boards_names = list()
    for Destination in boards:
     boards_names.append(Destination.destinationtext)
     response_html = '<br>'.join(boards_names)
     return HttpResponse(response_html)

我只是为了练习django框架而编写了这段代码，但是我通过pylint遇到以下错误：

I have written this code following just for practice of django framework but I am getting the following errors through pylint :

E1101:Class 'Destination' has no 'objects' member
E0601:Using variable 'Destination' before assignment

推荐答案

您有两个不同的问题，而不仅仅是您所说的一个：

You have two different issues, and not just one as you say:

E1101：类目标没有对象成员：是由于 pylint 不了解我们的特殊Django变量而发生的警告
。像 pylint-django 这样的pylint插件可能会解决问题。

E1101:Class 'Destination' has no 'objects' member: Is a warning that occurs because pylint doesn't know about our special Django variables. A pylint plugin like pylint-django might do the trick.

E0601：分配前使用变量 Destination ：在代码的for循环中定义了一个名为目的地。这不仅是不好的做法，因为python变量必须位于 lowercase_underscore 中，而且它会覆盖 Destination 类，这就是导致此错误的原因。您可能想执行以下操作：

E0601:Using variable 'Destination' before assignment: In the for loop in your code you defined a variable called Destination. This is not only bad practice because python variables need to be in lowercase_underscore but it overrides the Destination class, and that's what is causing this error. You probably wanted to do something like this:

for d in boards:
# Or:
for destination in boards:
