在Ubuntu下进行SQLAdmin的定制化开发,可以遵循以下建议:
安装必要的软件包:
sudo apt update
sudo apt install python3-pip git
安装SQLAdmin依赖: SQLAdmin通常依赖于一些Python库,可以使用pip安装:
pip3 install flask sqlalchemy psycopg2-binary
sqladmin/
├── app.py
├── config.py
├── models.py
├── forms.py
├── templates/
│ ├── index.html
│ ├── login.html
│ └── dashboard.html
├── static/
│ ├── css/

config.py来管理配置,包括数据库连接、密钥等敏感信息。import os
class Config:
SECRET_KEY = os.environ.get('SECRET_KEY') or 'your_secret_key'
SQLALCHEMY_DATABASE_URI = os.environ.get('DATABASE_URL') or 'postgresql://username:password@localhost/dbname'
SQLALCHEMY_TRACK_MODIFICATIONS = False
models.py中定义数据库模型,使用SQLAlchemy ORM。from flask_sqlalchemy import SQLAlchemy
db = SQLAlchemy()
class User(db.Model):
id = db.Column(db.Integer, primary_key=True)
username = db.Column(db.String(80), unique=True, nullable=False)
email = db.Column(db.String(120), unique=True, nullable=False)
def __repr__(self):
return '<User %r>' % self.username
from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmitField
from wtforms.validators import DataRequired, Email
class LoginForm(FlaskForm):
username = StringField('Username', validators=[DataRequired()])
password = PasswordField('Password', validators=[DataRequired()])
submit = SubmitField('Login')
app.py中定义视图函数,处理用户请求。from flask import Flask, render_template, redirect, url_for, flash
from config import Config
from models import db, User
from forms import LoginForm
app = Flask(__name__)
app.config.from_object(Config)
db.init_app(app)
@app.route('/')
def index():
return render_template('index.html')
@app.route('/login', methods=['GET', 'POST'])
def login():
form = LoginForm()
if form.validate_on_submit():
user = User.query.filter_by(username=form.username.data).first()
if user and user.password == form.password.data:
# 登录成功逻辑
return redirect(url_for('dashboard'))
else:
flash('Invalid username or password')
return render_template('login.html', form=form)
@app.route('/dashboard')
def dashboard():
return render_template('dashboard.html')
if __name__ == '__main__':
app.run(debug=True)
<!-- templates/index.html -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>SQLAdmin</title>
</head>
<body>
<h1>Welcome to SQLAdmin</h1>
<a href="{{ url_for('login') }}">Login</a>
</body>
</html>
flash功能来显示错误信息。import unittest
from app import app, db
from models import User
class SQLAdminTestCase(unittest.TestCase):
def setUp(self):
app.config['TESTING'] = True
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///test.db'
self.app = app.test_client()
db.create_all()
def tearDown(self):
db.session.remove()
db.drop_all()
def test_login(self):
user = User(username='test', email='test@example.com')
db.session.add(user)
db.session.commit()
response = self.app.post('/login', data=dict(username='test', password='password'), follow_redirects=True)
self.assertEqual(response.status_code, 200)
self.assertIn(b'Dashboard', response.data)
if __name__ == '__main__':
unittest.main()
通过以上步骤,你可以在Ubuntu下进行SQLAdmin的定制化开发,并确保项目的可维护性和安全性。
