• Is it possible to restrict how a method can be called in PHP?

  - by Ashley Ward

  Given that my class looks like this: class Methods{ function a(){ return 'a'; } function b(){ $this->a(); } function c(){ $this->a(); } } Is it possible to ensure that function a can only be called from function b? In the above example function c should fail. I could just include it in function b, but in the future I may want to let a() be called by some new functions (e.g. d() or e())

• Python: why can't descriptors be instance variables?

  - by Continuation

  Say I define this descriptor: class MyDescriptor(object): def __get__(self, instance, owner): return self._value def __set__(self, instance, value): self._value = value def __delete__(self, instance): del(self._value) And I use it in this: class MyClass1(object): value = MyDescriptor() >>> m1 = MyClass1() >>> m1.value = 1 >>> m2 = MyClass1() >>> m2.value = 2 >>> m1.value 2 So value is a class attribute and is shared by all instances. Now if I define this: class MyClass2(object) value = 1 >>> y1 = MyClass2() >>> y1.value=1 >>> y2 = MyClass2() >>> y2.value=2 >>> y1.value 1 In this case value is an instance attribute and is not shared by the instances. Why is it that when value is a descriptor it can only be a class attribute, but when value is a simple integer it becomes an instance attribute?

• How do I use a named_scope to filter records in my model

  - by kibyegon

  I have a model "Product" with a "description" field. Now I want to have a link in the index page that when clicked will show all products where the description is blank (empty). In the model I have defined a named_scope like this named_scope :no_description, :conditions => { :description => "" } I have checked that the named_scope works by calling Product.no_description.count on the console. As far as I know, the controller is then supposed to handle the filter request from the link on the "index" action but be able to distinguish it from the default which is view all products. def index @products = Product.all ... My problem is getting the controller handle the different request, what route to setup for the link on the view and the actual link on the view. Hope I explained my problem.

• Using functions and environments

  - by Eduardo Leoni

  Following the recent discussions here (e.g. 1, 2 ) I am now using environments in some of my code. My question is, how do I create functions that modify environments according to its arguments? For example: y <- new.env() with(y, x <- 1) f <- function(env,z) { with(env, x+z) } f(y,z=1) throws Error in eval(expr, envir, enclos) : object 'z' not found I am using environments to keep concurrently two sets of simulations apart (without refactoring my code, which I wrote for a single set of experiments).
