【问题描述】：
我在 python 中使用 SQLAlchemy 数据库，当我用文本文件打开时，数据库中的字符被编码并且无法理解。有谁知道我是否使数据库文件字符可读？任何答案都会得到认可。
这是我的编码数据库

我希望这些文本可读
这是我的python代码
from datetime import datetime, date
from flask import Flask, render_template, request, redirect, url_for
from flask_sqlalchemy import SQLAlchemy
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///medicine-app.db'
db = SQLAlchemy(app)
class Post(db.Model):
id = db.Column(db.Integer, primary_key=True)
title = db.Column(db.String(30), nullable=False)
detail = db.Column(db.String(100))
due = db.Column(db.DateTime, nullable=False)
@app.route('/', methods=['GET', 'POST'])
def index():
if request.method == 'GET':
posts = Post.query.order_by(Post.due).all()
return render_template('index.html', posts=posts, today=date.today())
else:
title = request.form.get('title')
detail = request.form.get('detail')
due = request.form.get('due')
due = datetime.strptime(due, '%Y-%m-%d')
new_post = Post(title=title, detail=detail, due=due) #making a new post from create
db.session.add(new_post)
db.session.commit()
return redirect('/')
@app.route('/create')
def create():
return render_template('create.html')
@app.route('/detail/<int:id>')
def read(id):
post = Post.query.get(id)
return render_template('detail.html', post=post)
@app.route('/update/<int:id>', methods=['GET', 'POST'])
def update(id):
post = Post.query.get(id)
if request.method == 'GET':
return render_template('update.html', post=post)
#update paged
else:
post.title = request.form.get('title')
post.detail = request.form.get('detail')
request.form.get('due')
post.due = datetime.strftime, '%Y-%m-%d'
db.session.commit()
return redirect('/')
#to database
#top page
@app.route('/delete/<int:id>')
def delete(id):
post = Post.query.get(id)
db.session.delete(post)
db.session.commit()
return redirect('/')
if __name__ == '__main__':
app.run(debug=True)
我也在使用 HTML
