这段代码定义了四个视图函数，用于管理员对机票信息进行管理。其中包括查看所有机票信息、搜索机票信息、添加机票信息以及更新和删除机票信息。在每个视图函数中都有对用户权限的检查，只有超级用户才能进行相应的操作。其中，查看所有机票信息和搜索机票信息的实现比较相似，都是获取请求中的筛选条件，并返回符合条件的机票信息。添加机票信息的实现是创建一个新的TicketItem对象和CheckinItem对象，并将其保存到数据库中。更新机票信息的实现是根据ticket_id获取TicketItem对象和对应的CheckinItem对象，并根据请求中的数据更新其属性值，然后将其保存到数据库中。删除机票信息的实现是根据ticket_id获取对应的TicketItem对象，并将其从数据库中删除。最后，每个视图函数都会返回相应的HTML页面和机票信息。
