Dear Everybody I am doing a Django tutorial on Templates. I am currently at this code: from django.template import Template, Context >>> person = {'name': 'Sally', 'age': '43'} >>> t = Template('{{ person.name }} is {{ person.age }} years old.') >>> c = Context({'person': person}) >>> t.render(c) u'Sally is 43 years old.'

Hi all, I'm having a problem when trying to compile these two classes (Army and General) in their own header files: #ifndef ARMY_H #define ARMY_H #include "definitions.h" #include "UnitBase.h" #include "UnitList.h" #include "General.h" class Army { public: Army(UnitList& list); ~Army(void); UnitBase& operator[](con...
I'm trying to use an RTF file as a template for generating a new RTF document containing a page per (mysql) database row. My method almost works except that the generated file contains only one page, with the first row, and not one page for each row. (there should be 2 pages in my test). Here is the main loop. $today= date('d-m-Y'); $...
Hi, I have an abstract class vertex which represents an n-tuple. The element of the vertex can be of any type: ie, the vertice's components could be of type int, int, float or something. Because the vertex can have an arbitrary number of dimensions, I was thinking of making the class have a component setter like so: class vertex { ...
I have a method in C# as follows (which wraps a number across a range, say 0 to 360... if you pass 0-359 you get the same value, if you pass 360 you get 0, 361 gets 1, etc.): /// <summary> /// Wraps the value across the specified boundary range. /// /// If the value is in the range <paramref name="min"/> (inclusive) to ...
I'm using Visual Studio 2008. I have this class: template <bool T1> class Foo { public: void doSomething() {} Foo<T1>& operator=(int a) { doSomething(); return *this; } }; But I want that the method operator= be hidden (by simply doing: return *this) if the template parameter T1 is false. I need that for ...
Imagine the following template class (setter and getter for the member _t omitted): template<class T> class chain { public: static chain<T> NONE; chain() : _next(&NONE) {} ~chain() {} chain<T>& getNext() const { return *_next; } void setNext(chain<T>* next) { if(next && next != this) _next = next; ...
I'm trying to wrap my head around the best way to do a templating system for my PHP CMS. I'm a little stuck and so I'm looking for a few suggestions or ideas. Here is my desired setup: Each page is composed of various widgets (or content blocks, if you prefer). Each widget has an MVC architecture, with the View being simple, composed of...

Why am I getting undefined references to the methods in this class when I call them? Will I be forced to include the implementation in the header file or is there another way to do this better? class MathHelper { public: /*!

Hi, I was wondering if there was a ternary operator (condition ? true-value : false-value) that could be used in a Django template. I see there is a python one (true-value if condition else false-value) but I'm unsure how to use that inside a Django template to display the html given by one of the values. Any ideas? ...
Boost has both enable_if and disable_if, but C++0x seems to be missing the latter. Why was it left out? Are there meta-programming facilities in C++0x that allow me to build disable_if in terms of enable_if? Oh, I just noticed that std::enable_if is basically boost::enable_if_c, and that there is no such thing as boost::enable_if in C...
I have a template method that is designed to work with a specific set of classes. Since I have no real need for runtime polymorphism, I've decided to not use pointers to the parent class, but rather will have the compiler put everything together for me. I want to either restrict the type that can be passed to the template, or make GCC ...

I am trying to create a generic "callback" object that will hold arbitrary data and invoke member functions of related classes. Due to internal policy, I cannot use Boost. The callback object looks like this: template<typename Object, typename Data> class Callback { public: typedef void (Object::*PHandler)(Callback*); Callback(Obj...
