Factory Girl is a handy framework in rails for easily creating instances of models for testing. From the Factory Girl home page: factory_girl allows you to quickly define prototypes for each of your models and ask for instances with properties that are important to the test at hand. An example (also from the

AngularJS - Changing a query param term within $routeProvider?

由 安稳与你 提交于 2019-12-08 11:03:17
问题 I am creating a navigation, where when on the active 'link', a feed loads but with a different searched term. Basically, the all the links are the same, the only difference is the term set in the .factory parameter. Since everything is the same (even the .controller, is it possible to set the query term inside of the routeProvider, where I can specify the term that needs to be searched? Or will the only way is to create a new controller for each link, and set the term inside of there? Keeping

Generic Return Type Based on Class

由 本小妞迷上赌 提交于 2019-12-08 04:37:32
问题 I'm trying to create factory method on a class that automatically casts to the class it's on. extension NSObject { // how can I get the return type to be the current NSObject subclass // instead of NSObject? class func create() -> NSObject { return self.init() } // example: create(type: NSArray.self) class func create<T:NSObject>(type:T.Type) -> T { return T() } } Example two works, but gets NO advantage from being a class method: let result = NSArray.create(type: NSArray.self) But I'd love

python setattr for dynamic method creator with decorator

由 大憨熊 提交于 2019-12-08 02:25:47
问题 I have a class which has multiple methods defined. import mat class Klass(object): @mat.sell(mat.CanSet): def method1(self): return None @mat.sell(mat.CanSet): def method2(self): return 'value2' Imagine I have 10 methods that I need to populate for this 'Klass'. I want to generate these methods without explicitely writing them all. So I want to do a factory that does setattr for each method. Problem is that I do following and the last method has the last value. Each do not get its related

Passing arguments in constructor with boost factory

由 我只是一个虾纸丫 提交于 2019-12-08 00:39:01
问题 I am fairly new with the whole factory implementation and as a result maybe my question will sound wrong and not very well defined. So, with few words I want to have a boost factoty in order to initialize a banch fo derived classes and so far I have managed to do so for classes with empty constructors. Let me present to my current boost factory implementation for two small classes: Base.h: #ifndef BASE_H_ #define BASE_H_ #include <vector> #include <map> #include "boost/function.hpp" class

PHP Extending class makes children inherit same static property

问题 I'd like to start by showing a test case: class A { public static $instance=null; public function __construct(){ self::$instance=$this; } public function className(){ return get_class(self::$instance); } } class B extends A { public function className(){ return get_class(self::$instance); } } // test code $b=new B(); echo $b->className; // B $a=new A(); echo $a->className; // A echo $b->className; // A <- error: not B any more! Notes I'm using a factory+singleton patterns above. Well,

NInject Extension Factory

问题 After reading the new documentation on NInject v3 and how to use the Factory Extension , apparently I still don't get it fully since my code throws exceptions all over the place... I get this Exception, i could paste the whole thing if people would like that but i'll try and keep it short for now. Error activating IDeployEntityContainer No matching bindings are available, and the type is not self-bindable. Here is my code... The Ninject Bind Module class class MyNinjectModule : NinjectModule

小菜学设计模式——简单工厂模式

由 萝らか妹 提交于 2019-12-07 21:03:38
背景 很多时候我们不知道客户具体需要执行哪种类型的操作，但是客户会给出我们对应的提示信息，那么我们的程序必须能够根据参数信息进行动态操作，这样的程序才是一个可扩展的程序。简单工厂模式应该是我们最常见的一种设计模式之一，他就是根据客户的意图选择对应的执行类型进行操作，实际上就是根据不同的参数实例化出不同的对象，所以叫做工厂。 1、使用意图 根据参数的不同实例化出对应的类型对象，对于那些需要大量 生成相同父类实例的程序，他可以避免了代码的重复。 2、生活实例 生活处处是例子 3、Java 例子（框架、JDK 、JEE） 曾经写过一个工具类，关于使用iReport生成html、excel、pdf、doc的报表的SDK，客户只需要传入数据和想要的报表类型，我就可以为他生成对应的类型的数据报表。这就是一个典型的简单工厂模式，一个工厂类 ReportFactory，一个总接口，IExport，声明导出方法export，然后，分别实现报表类型的导出方法。 4、模式类图 5、模式优点 个人觉得这个模式，最大的优点就是避免了代码重复，其次，逻辑上比较清晰。其他的优点估计都是缺点了吧，最大的缺点就是：违背了开放封闭原则，当你想要扩展一种类型的时候，不得不修改工厂类的工厂方法。 6、与类似模式比较 暂时还没有深究其他的工厂模式（工厂方法模式、抽象工厂模式），所以，也没什么好计较的。 另外
