Question

所以我在Flask（Python网站）中使用flask_mysqldb

我正在尝试编写一个函数来删除任何表中的行。当我对表名进行硬编码时它非常有效，但是我需要做些什么才能使用变量呢？

@app.route('/delete/<string:table>/<string:id>', methods=['POST'])
@is_logged_in
def delete(table, id):
  # Create Cursor
  cur = mysql.connection.cursor()

  # Execute
  cur.execute("DELETE FROM %s WHERE id = %s", (table, id))

  mysql.connection.commit()

  cur.close()

  flash('%s deleted'(table), 'success')

  return redirect(url_for('dashboard'))

Answer 1

cur.execute("DELETE FROM %s WHERE id = %s", (table, id))

应该是

cur.execute("DELETE FROM %s WHERE id = %s" % (table, id))

flask_mysqldb删除FROM变量表
