How can I set the default where/sort condition in my SailsJS waterline model? In Rails I would use default scope . Sails doesn't support default criteria on a per-model basis, but if you're using blueprint routes you can set default criteria for the route by overriding in your config/routes.js file, for example: "GET /user": { controller: 'user', action: 'find', where: {'deleted': false}, sort: 'age DESC' } This will work even if you don't have a find action defined in your UserController.js file, because the blueprint is added for you by default. 来源： https://stackoverflow.com/questions

Stimulsoft Reports.Wpf 是针对WPF开发的报表工具 控件 。无需上网，所有的WPF功能都能用上！丰富的界面更换功能、查看功能、打印以及导出报表功能——所有的这一切就是它都能轻松实现。 创建 Stimulsoft Reports.Wpf是基于Stimulsoft团队多年开发以及使用的报表引擎来创建报表。只需简单的几行代码即可执行报表复杂的操作，报表引擎提供了创建报表的许多功能。大量的 组件 开发包，独特的一套属性和参数，精心构思的报表体系。很多选项都是绝对独特且仅出现该产品中。Stimulsoft团队更加注重报表呈现的速度以及复杂报表的创建。 设计 我们提供了强大的报表设计器用于创建报表，这个报表设计器是基于WPF技术的。这个报表设计器的先进功能非常的多：友好的用户界面，多页报表模板、样式、多语言支持，所以需要很多时间来描述它所有的特性、建议您试用了之后来了解它的工作方式，您将会喜欢上它。 存储 我们希望尽量减少 软件开发 者的工作。因此我们添加了许多保存报表的选项。报表可以保存为文件、字符串、数组、数据库字段、也可以被封装。另外，报表还可以编译为.NET程序集，然后在你的项目中直接使用。单个的报表对于Stimulsoft Reports.Wpf.来说不是问题。报表甚至可以保存为C#或VB.NET的类。 浏览 报表工具中最重要的一部分就是报表浏览器

Thanks for reading. I am using Devise and Rails 4. I want to add multiple User Models(admin, usertype1, usertype2) such that they inherit from the main User Model. I have searched many posts and come to the conclusion that I may use CanCan, which I do not want, or I may use Single Table Inheritance. The way I see it is to add a type string-column to my main User model I created with Devise. I will also need to extend each sub-class from the parent as in: class Admin < User end class Usertype1 < User end class Usertype2 < User end My question is: what do I do next? How exactly do I know how to

Previously, I asked this question about compound indexes on polymorphic foreign keys in ActiveRecord . The basis of my question was my understanding that indexes should be based on the cardinality of your column, and there's generally pretty low cardinality on Rails's STI type and polymorphic _type columns. Accepting that the answer to my question is right -- that's there's value to indexing both the high cardinality _id columns and the low cardinality _type columns, because they together they have a high cardinality -- my next question is: how should you order your compound indexes? An index

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: I am running around ten AsyncTasks after my application starts. Sometimes the emulator takes a long time to start these tasks. When this occurs, I see the following message in the log cat: D/dalvikvm(1983): threadid=8: still suspended after undo (sc=1 dc=1 s=Y) When the emulator executes quickly this message doesn't appear. Strangely, this behavior changed today without any modifications. Since I have explicitly assigned 512mb ram to the emulator, it is no longer extremely slow ~5min, now ~5s. On a real device I never have execution that

WPE效应主要影响SPICE的Well Proximity Effect Model，WPE对MOS特性的影响主要体现在阈值电压、迁移率和体效应上。WPE效应与FET和MASK边缘距离强相关，BSIM4中WPE效应影响的阈值电压、迁移率、和体效应所对应Model参数分别为VTH0、U0、K2，通过SCA、SCB和SCC三个参数对上面三个参数产生影响。 在对WPE的建模主要考虑时FET与阱四周的距离该距离会直接影响整体器件的净注入量，用SC来统称FET与各边的距离，其又分成四个小参数SC1、SC2、SC3、SC4用来代表FET与四边的距离，那么可以通过线积分求得SCA、SCB、SCC的值。 公式中fA(s)、fB(s)、fC(s)定义如下： 公式中对SCref的定义为一个经验数据拟合得到的固定参数值。 文章来源: https://blog.csdn.net/cocoqoo/article/details/92643713

I am am developing a recruitment application for storing records of people who come for an interview. So I have two models - Applicant & Employee which seem like one in OO sense. i.e. Employee was earlier an applicant. Therefore I am planning to create a Single table inheritance like: Applicant < Person Employee < Person All the fields of Applicant are there in Employee. Employee has several other fields that are not in Applicant. Am I correct with this plan. I have another similar scenario to deal with - prospects & clients. Update: As I am working more and more with STI, I am starting to

1 直接开启sti --蓝屏 2 配置环境 正确开启sti 中断 kpcr -- 很多重要线程切换的数据、结构 进入内核的时候 fs 不再是teb/tib； 是 kpcr 。 同时观察 kifastcallentry，发现 的确设置了 fs 为内核的 kpcr： 那我们手动修改成 kpcr ； 注意： 如果 直接使用fs 不行；那么就查相关硬编码 来代替。 效果 系统不卡，且任何方式杀不掉，关机也杀不掉： 当前系统不卡死了，能线程调度了；但是 测试的程序 不能被杀死，也结束不了， 因为结束线程是 插入 apc队列请求，是异步过程 ；因为结束线程并不是马上结束的，肯定需要执行到特定的环境，不然执行到一个语句就切，那么环境就是错误的，可能导致蓝屏、%100导致错误。 线程结束实际过程： 从 0 环返回3环 之前；系统会检查其 apc 队列，查看是否有结束的请求。有 就杀死（如果是进程的最后的一个线程，那就把对应进程给清理掉） 但是这里： 在 0环一直死循环；导致不会切换到3环的瞬间之前检查；所以杀不掉。 怎么杀掉： ---- 只有修改 破环那个死循环。 !process 0 0 .process 对应的_eprocess u 0xaddr ew 401005 9090 修改。。。 nop掉。就可以杀死并关机了 来源： https://www.cnblogs.com/leibso-cy
