Flask - 提交按钮操作 Sqlite3（Db 浏览器 Sqlite）

Question

单击提交按钮后，我想将表单保存到 DB Browser Sqlite 上。 该数据库称为 pettycash.db。 表名是 SubmitClaim。 我已经在数据库中创建了相应的字段。 我需要使用 INSERT STATEMENT 中的字段名称还是使用我在 request.form['name'] 等中使用的名称？

应用程序.py

@app.route('/addrec', methods=['POST', 'GET'])

def addrec():

    if request.method == 'POST':
        name = request.form['name']
        depart = request.form['depart']
        type = request.form['type']
        uploadre = request.form['uploadre']
        amt = request.form['amt']
        price = request.form['price']
        description = request.form['description']

    conn = sql.connect('pettycash.db')
    c = conn.cursor()

    c.execute(
        "INSERT INTO SubmitClaim VALUES (?,?,?,?,?,?,?)", (name, depart, type, uploadre, amt, price, description))

    conn.commit()

    c.execute("SELECT * FROM SubmitClaim")
    print(c.fetchall())
    conn.close()

提交claim.html

您需要在 sqlite 数据库中创建表。 在创建表格时，无论您需要什么，都可以提及列。

插入数据时，需要使用 Table 的列名。
