Question

我的问题是我无法通过python shell添加用户。然后，如果我从应用程序导入类Admin，但出现错误，则添加用户 NameError: name 'Admin' is not defined。

在models.py

中

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from sqlalchemy import Table, Column, Integer, ForeignKey, DateTime
from sqlalchemy.orm import relationship

class Admin (db.Model):
    idAdmin = db.Column(db.Integer, primary_key=True)
    login = db.Column(db.String(255))
    password = db.Column(db.String(255))
    pin = db.Column(db.Integer)
    name = db.Column(db.String(255))
    surname = db.Column(db.String(255))

    def __repr__(self):
        return f"Admin('{self.name}','{self.surname}')"

在初始 .py

中

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from model import db
from flask_wtf.csrf import CSRFProtect
import os

app = Flask(__name__)

file_path = os.path.abspath(os.getcwd()) + "\database.db"
app.config["SQLALCHEMY_DATABASE_URI"] = "sqlite:///" + file_path

db = SQLAlchemy()
db.create_all()

根据https://flask-sqlalchemy.palletsprojects.com/en/2.x/quickstart/ 我必须考虑：

>>> from app import db
>>> db.create_all()
>>> from app import Admin
>>> admin = Admin(username='John', password='1qaz@WSX', pin='1234', name='John', surname='Trump')
>>> db.session.add(admin)
>>> db.session.commit()

输入命令>>> admin = Admin(username='John', password='1qaz@WSX', pin='1234', name='John', surname='Trump')后我收到错误消息NameError: name 'Admin' is not defined

您的导入似乎应该

from app.models import Admin

无法从Shell python
