在flask中使用SQL炼金术将数据插入Postgres

pip install SQLAlchemy
pip install psycopg2

# 配置文件中的数据库连接信息
SQLALCHEMY_DATABASE_URI = 'postgresql://username:password@localhost/database_name'
SQLALCHEMY_TRACK_MODIFICATIONS = False

from flask_sqlalchemy import SQLAlchemy

db = SQLAlchemy()

class User(db.Model):
    __tablename__ = 'users'
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(50), unique=True, nullable=False)
    email = db.Column(db.String(120), unique=True, nullable=False)

    def __init__(self, username, email):
        self.username = username
        self.email = email

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config.from_object('config')
db = SQLAlchemy(app)

db.create_all()

from flask import Flask, request
from models import User, db

@app.route('/user', methods=['POST'])
def create_user():
    username = request.form.get('username')
    email = request.form.get('email')

    user = User(username=username, email=email)
    db.session.add(user)
    db.session.commit()

    return 'User created successfully'
