Pylint找不到SQLAlchemy查询成员 [英] Pylint can't find SQLAlchemy query member

问题描述

我有一个使用Flask-SQLAlchemy(v2.0)的Flask(v0.10.1)应用程序，并且我正在尝试配置Pylint进行检查.使用Python 3.4.2.运行.

I have a Flask (v0.10.1) application using Flask-SQLAlchemy (v2.0) and I'm trying to configure Pylint to check it. Running with Python 3.4.2.

第一个错误是:

 Instance of 'SQLAlchemy' has no 'Table' member (no-member)

我修复了这个问题，而忽略了对SQLAlchemy成员属性的检查:

And I fixed this one ignoring the check for member attributes on SQLAlchemy:

ignored-classes=SQLAlchemy

但是我在实体上的查询成员遇到了问题:

But I'm having a problem with the query member on entities:

Class 'UserToken' has no 'query' member (no-member)

有什么方法可以解决此问题，而不必在每次查询调用时都忽略无成员错误?

Is there any way to fix this issue without having to ignore no-member errors on every query call?

烧瓶引导程序:

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

db = SQLAlchemy()
app = Flask(__name__)
db.init_app(app)
app.run()

UserToken实体:

UserToken entity:

from app import db

class UserToken(db.Model):
    user_token_id = db.Column(db.Integer, primary_key=True, index=True)
    token_auth = db.Column(db.String(64), unique=True, nullable=False, index=True)

控制器:

from entities import UserToken

token = UserToken.query.filter(
    UserToken.token_auth == token_hash,
).first()

推荐答案

解决方案

pip install pylint-flask

pip install pylint-flask-sqlalchemy

加载已安装的插件.

例如，如果您使用VS代码，请按如下方式编辑settings.json文件:

For example, if you use VS code, please edit settings.json file as follows:

"python.linting.pylintArgs": ["--load-plugins", "pylint_flask_sqlalchemy", "pylint_flask"]

如果还有其他警告，请在pylintrc文件的generated-members中定义其余成员.

If having other warnings, define remaining members in generated-members in pylintrc file.
