The code below represents a situation where the same code pattern repeats in every controller which handles data from the server. After a long research and irc talk at #angularjs I still cannot figure how to abstract that code, inline comments explain the situations: myApp.controller("TodoCtrl", function($scope, Restangular, CalendarService, $filter){ var all_todos = []; $scope.todos = []; Restangular.all("vtodo/").getList().then(function(data){ all_todos = data; $scope.todos = $filter("calendaractive")(all_todos); }); //I can see myself repeating this line in every //controller dealing with

I've read that you can have @Autowired generics as of Spring 4, which is awesome. I have an abstract RedisService class in which I want to have @Autowired a generic RestTemplate, like so: public abstract class RedisService<T> implements InitializingBean { private final String VALUE_KEY_PREFIX; private final String SET_KEY; @Autowired private RedisTemplate<String, T> valueTemplate; @Autowired private StringRedisTemplate stringTemplate; private SetOperations<String, String> setOperations; private ValueOperations<String, T> valueOperations; // and so on... } My Java config for the valueTemplate s

I have a boiler platey class that delegates some actions to a reference class. It looks like this: class MyClass(): def __init__(self, someClass): self.refClass = someClass def action1(self): self.refClass.action1() def action2(self): self.refClass.action2() def action3(self): self.refClass.action3() This is the refClass: class RefClass(): def __init__(self): self.myClass = MyClass(self) def action1(self): #Stuff to execute action1 def action2(self): #Stuff to execute action2 def action3(self): #Stuff to execute action3 I'd like to use Python Metaprogramming to make this more elegant and

I'm relatively new to Rails and a bit surprised this isn't a configurable behavior...at least not one I've been able to find yet?!? I would have thought that 99% of forms would benefit from whitespace being trimmed from all string & text fields?!? Guess I'm wrong... Regardless, I'm looking for a DRY way to strip all whitespace from form fields (of type :string & :text) in a Rails 3 app. The Views have Helpers that are automatically referenced (included?) and available to each view...but Models don't seem to have such a thing?!? Or do they? So currently I doing the following which first

I'm designing a re-usable class library that contains 2 assemblies (amongst others) named core.xml.dll and core.string.dll. The xml assembly references the string assembly in order to use some string helper methods. However now there is an string method that would be benefit from using a method contained in the xml assembly. If I reference the xml assembly from the string assembly I will have created a circular dependency and will be unable to build both assemblies from source code. (ie chicken and the egg problem). In order to follow the "Don't Repeat Yourself" principle I would like to avoid

This question already has answers here : Closed 7 years ago . Possible Duplicate: Pass a PHP string to a Javascript variable (and escape newlines) I have several constants in a PHP application I'm developing. I've defined a Constants class and the defined the constants as const VAR_NAME = value; in this class. I would like to share these constants between my JavaScript and PHP code.
