flask_mysqldb删除FROM变量表 [英] flask_mysqldb Delete FROM variable table

问题描述

所以我在Flask(Python网站)中使用flask_mysqldb

So i use flask_mysqldb in a Flask(Python website)

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，它可以完美地工作，但是我需要做些什么才能能够使用变量呢?

I'm trying to write a function to delete a row in any table. It works perfectly when I hardcode the tablename, but what do I need to do to be able to use a variable instead?

@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'))

推荐答案

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

应该是

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