使用Python语言设计一个餐厅点单系统
抱歉,由于基于Python的点餐系统的实现涉及到很多细节和功能模块,无法在一个回答中展示完整的代码。但是,我可以给您提供一些实现的思路和代码片段,希望对您有所帮助。
1. 使用Flask框架搭建后端服务器:
```python
from flask import Flask, render_template, request
from flask_sqlalchemy import SQLAlchemy
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://username:password@localhost/databasename'
db = SQLAlchemy(app)
class Menu(db.Model):
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(100))
price = db.Column(db.Float)
category = db.Column(db.String(50))
class Order(db.Model):
id = db.Column(db.Integer, primary_key=True)
customer_name = db.Column(db.String(100))
customer_phone = db.Column(db.String(20))
order_items = db.relationship('OrderItem', backref='order')
class OrderItem(db.Model):
id = db.Column(db.Integer, primary_key=True)
order_id = db.Column(db.Integer, db.ForeignKey('order.id'))
menu_id = db.Column(db.Integer, db.ForeignKey('menu.id'))
quantity = db.Column(db.Integer)
@app.route('/')
def index():
menus = Menu.query.all()
return render_template('index.html', menus=menus)
@app.route('/order', methods=['POST'])
def order():
customer_name = request.form['customer_name']
customer_phone = request.form['customer_phone']
order_items = []
for menu_id, quantity in request.form.items():
if menu_id.isdigit() and int(quantity) > 0:
menu = Menu.query.get(menu_id)
order_items.append(OrderItem(menu=menu, quantity=quantity))
order = Order(customer_name=customer_name, customer_phone=customer_phone, order_items=order_items)
db.session.add(order)
db.session.commit()
return 'Order placed successfully!'
```
2. 使用Bootstrap实现前端网页界面的设计:
```html
<!DOCTYPE html>
<html>
<head>
<title>Menu</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
</head>
<body>
<div class="container">
<h1>Menu</h1>
<form method="POST" action="/order">
<table class="table">
<thead>
<tr>
<th>Name</th>
<th>Price</th>
<th>Quantity</th>
</tr>
</thead>
<tbody>
{% for menu in menus %}
<tr>
<td>{{ menu.name }}</td>
<td>{{ menu.price }}</td>
<td><input type="number" name="{{ menu.id }}"></td>
</tr>
{% endfor %}
</tbody>
</table>
<div class="form-group">
<label for="customer_name">Name:</label>
<input type="text" class="form-control" id="customer_name" name="customer_name" required>
</div>
<div class="form-group">
<label for="customer_phone">Phone:</label>
<input type="text" class="form-control" id="customer_phone" name="customer_phone" required>
</div>
<button type="submit" class="btn btn-primary">Order</button>
</form>
</div>
</body>
</html>
```
