Question

我正在创建一个基于网络的POS系统。用户点击“订单提交”后，数据将通过此架构提交：

CREATE TABLE orders (
    transaction_id integer primary key autoincrement,
    total_price integer not null
);
CREATE TABLE order_items (
    transaction_id integer REFERENCES orders(transaction_id),
    SKU integer not null,
    product_name text not null,
    unit_price integer not null,
    quantity integer not null
);

通过这个烧瓶代码：

@app.route('/load_ajax', methods=["GET", "POST"])
def load_ajax():
    if request.method == "POST":
        data = request.get_json()
        for group in groupby(data, itemgetter('name')):
            id, data_list = group
            for d in data_list:
                print d['subtotal']
                db = get_db()
                db.execute('insert into order_items (SKU, product_name, unit_price, quantity) values (?, ?, ?, ?); insert into orders (total_price) values (?)',
                [d['sku'], d['name'], d['price'], d['quantity']],[d['subtotal']])
                db.commit()
        return jsonify(location=url_for('thankyou'))

我收到500错误，我不确定为什么会这样。我是否需要执行两个不同的db.execute语句？

是的，您需要使用两个不同的.execute()语句。引用cursor.execute() documentation：

execute()只会执行一个SQL语句。

所以这样做：

db.execute('insert into order_items (SKU, product_name, unit_price, quantity) values (?, ?, ?, ?)',
           (d['sku'], d['name'], d['price'], d['quantity']))
db.execute('insert into orders (total_price) values (?)',
           (d['subtotal'],))
