performance-free because you do not need to make any connections to access multiple subclasses, ActiveRecord can use the Type column to determine which records can be returned. In some respects, ActiveRecord inheritance is very limited. If an existing inheritance level is very wide, inheritance is invalidated. For example, in Changingthepresent, there are many types of content, each with its own name, a short or long description, some common presentation properties, and several custom attribut

. Each type has its own name, short or long description, some common representation attributes, and several custom attributes. We hope that cause, nonprofit, gift, member, drive, registry, and other types of objects can be inherited from the general base class, so that we can process all types of content in the same way. But we cannot, because the Rails Model will have the essence of all our object models in a single table, which is not a feasible sol

students.The survey also found that students are not as fond of the pharmaceutical and consumer goods industries as they used to be. For example, in the past, the top 10 Johnson Johnson companies in the rankings fell from 8th to 18, while the Abbott lab slipped from 54th to more. At the same time, companies in the consumer goods field also began to decline, such as P G (down from 14 to 21) and L'Oreal (down from 27 to 35 ).According to statistics, the number of students involved in the su

. MageiaMageia is a gnu/linux-based computer operating system and free software for everyone to use. The hero behind the development of this release is the group of employees who developed the Mandriva Linux for the French company. The first version was released in September 2010. The second version came into existence in May 2012. The Mageia includes Gnome 3.4, KDE4 SC 4.8.2, LXDE, XFCE 4.9, RAZOR-QT, and E17. It is very stable and reliable, hardware requirements are not high, on the very weak

-known Linux distribution and is a fast, stable and powerful operating system for everyday applications built by community enthusiasts around the world. It allows anyone to use, modify, and redistribute freely, both now and in the future. It is developed by a strong community of members who, with their tireless efforts, provide and maintain free, open-source software and open standards.Official website: http://fedoraproject.org/: Http://fedoraproject.org/zh_CN/get-fedoraMageiaSystem: LinuxBased

The logo of Linux is a very cute little penguin, and FreeBSD's logo is a small demon with a fork. Do you often hear people confuse Linux and BSD systems? Yes, I sometimes hear a lot of newbies, even the media say so. Of course, there are actually a lot of similarities between the two, for example, they are all based on Unix, and basically both of these systems are developed by nonprofit organizations and teams, and I would like to say that both system
