Flask笔记-通过Model访问数据库

这个类似与Java的MyBatis。

这样的话开发就快速很多了！

程序运行截图如下：

程序结构如下：

源码如下：

account.py

from application import db

class Account(db.Model):
    id = db.Column(db.Integer, primary_key = True)
    name = db.Column(db.String(50))
    password = db.Column(db.String(50))

index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<p>Flask 查询数据库</p>
<p>
    {% for item in result %}
    {{item['id']}}  {{item['name']}}  {{item['password']}}
    {% endfor %}
</p>
</body>
</html>

application.py

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)

app.config["SQLALCHEMY_DATABASE_URI"] = "mysql://root:[email protected]/mytest"
db = SQLAlchemy(app)

controller.py

from flask import Flask,Blueprint,request,make_response,jsonify,render_template
from sqlalchemy import text
from application import db
from common.models.account import Account



index_page = Blueprint("index_page", __name__)

@index_page.route("/sql")
def sqlQuery():
    context = {}
    result = Account.query.all()
    context["result"] = result
    return render_template("index.html", **context)

manager.py

from application import app
from www import *

if __name__ == "__main__":
    app.run(host = "0.0.0.0", debug = "True")

www.py

from application import app
from controller import index_page

app.register_blueprint(index_page, url_prefix = "/it1995")
