flask靈活的文件組織結構讓很多新手玩家痛苦萬分,網(wǎng)上的相關教程也是良莠不齊,本人也是在幾近崩潰的邊緣瘋狂試探
,堅持即時勝利,終于被我摸索出一個較為適用的簡單文件組織結構. 本文從單文件結構,逐步拆分成多個部分,至于其中
各個步驟拆分的用意,還請恕在下才疏學淺,難以用文字形容,各位看官請自行體會.

        content = request.form.get("content")
        print("content={}".format(content))
        record = Record(name=name, content=content)

                                                                       DATABASE)

sign_up.html

    
    


    

        用戶名
        密 碼
        
    

首先我們在根目錄中新建一個extensions.py,將app.py中的頭部部分拿進去
extensions.py

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
import config

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

然后在根目錄中新建models包,并在models里面新建record.py文件
record.py

from extensions import db
class Record(db.Model):
    __tablename__ = "record"
    id = db.Column(db.Integer, primary_key=True, autoincrement=True)
    name = db.Column(db.String(100), nullable=False)
    content = db.Column(db.Text, nullable=False)

接著在根目錄下新建routes包,并在routes里面新建record.py的路由文件

from extensions import app,db
from flask import render_template, request, redirect, url_for
from models.record import Record


@app.route("/")
def index():
    return render_template("index.html")


@app.route("/sign_up", methods=["GET", "POST"])
def add_user():
    if request.method == "GET":
        return render_template("sign_up.html")
    else:
        for i in request.args:
            print(i)
        # print(request.args.get("username")) #None
        name = request.form.get("name")
        print("name={}".format(name))
        content = request.form.get("content")
        print("content={}".format(content))
        record = Record(name=name, content=content)
        db.session.add(record)
        db.session.commit()
        return redirect(url_for("index"))

最后在根目錄中新建一個入口文件run.py

run.py

from extensions import db
from routes.record import app
if __name__ == "__main__":
    db.init_app(app)

    app.run()

數(shù)據(jù)庫初始化比較簡單,請自行建庫建表,修改連接配置
自此大功告成,邁過flask的第一大坑
