“ OneToOneField”的实例没有“用户名”成员 [英] Instance of 'OneToOneField' has no 'username' member

问题描述

创建个人档案模型时出现以下错误

I got the following error when I created Profile model

OneToOneField的实例没有用户名成员

Instance of 'OneToOneField' has no 'username' member

这是我创建的代码的片段

This is the snippet of the code I created

from django.db import models
from django.contrib.auth.models import User
class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    image = models.ImageField(default="default.jpg", upload_to="profile_pics")

    def __str__(self):
        return f"{self.user.username} Profile"

以前运行正常。现在，突然我收到了这个错误。我不明白该错误的含义。我该如何解决？
谢谢

推荐答案

为了使pylint与Django正常工作，您应该安装 pylint-django packege：

In order for pylint to work properly with Django you should install the pylint-django packege:

pip install pylint-django

然后您可以使用 pylint_django pylint $ c>作为插件：

Then you can run pylint with pylint_django as a plugin:

pylint --load-plugins pylint_django <path_to_django_file>

如果您将VSCode用作IDE，则可以将此代码段添加到 .vscode / settings.json 文件为您的项目加载插件：

If you are using VSCode as your IDE, you can add this snippet to your .vscode/settings.json file to load the plugin for your project:

{
    "python.linting.pylintArgs": [
        "--load-plugins",
        "pylint_django"
    ]
}

或者，如果您有 .pylintrc 文件，则可以添加此行以加载插件：

Or, if you have a .pylintrc file, you can add this line to load the plugin:

[MASTER]
load-plugins=pylint_django
