  • django ifequal naturalday

    - by Scott Willman
    I'm not sure why, but this condition will never evaluate True for me. I'm feeding it datetime.today() in the urls file. Am I missing something? Template: {% load humaize %} {{ entry.date|naturalday }} {# Evals to "today" #} {% ifequal entry.date|naturalday "today" %} True {{ entry.date|date:"fA"|lower }} {{ entry.date|naturalday|title }} {% else %} False {{ entry.date|naturalday|title }} {% endifequal %}

  • Tapestry5 : No service implements the interface org.springframework.context.ApplicationContext

    - by Joel
    I'm using the Tapestry5 tapx template library to send an html email, as per this example. When I run the example I get the following error: Caused by: java.lang.RuntimeException: No service implements the interface org.springframework.context.ApplicationContext. at org.apache.tapestry5.ioc.internal.RegistryImpl.getService(RegistryImpl.java:560) at org.apache.tapestry5.ioc.internal.ObjectLocatorImpl.getService(ObjectLocatorImpl.java:44) All the tapestry-* jars, including tapestry-spring-5.1.05.jar are in my classpath. Any clues as to what I'm missing?

  • C++ R - tree implementation wanted

    - by Kotti
    Hi, Does anyone know good and simple to use in production code R-tree (actually, any implementations - R*, R+ or PR-tree would be great)? It doesn't matter if it is a template or library implementation, but some implementations that google found look very disappointing... Thanks in advance.

  • decltype, result_of, or typeof?

    - by Neil G
    I have: class A { public: B toCPD() const; And: template<typename T> class Ev { public: typedef result_of(T::toCPD()) D; After instantiating Ev<A>, the compiler says: meta.h:12: error: 'T::toCPD' is not a type neither decltype nor typeof work either.

  • How do I create a clicked state in a SIlverlight button?

    - by Roy
    How do I create a clicked state in visual state manager for a control that is based on a button control? I tried using a pressed state but once the mouse button is released it reverts back to the original color. I would like to change the color of the button when it is clicked on. I am not looking for a solution in the click event handler because this is a part of a template. Thank you

  • overloading new/delete problem

    - by hidayat
    This is my scenario, Im trying to overload new and delete globally. I have written my allocator class in a file called allocator.h. And what I am trying to achieve is that if a file is including this header file, my version of new and delete should be used. So in a header file "allocator.h" i have declared the two functions extern void* operator new(std::size_t size); extern void operator delete(void *p, std::size_t size); I the same header file I have a class that does all the allocator stuff, class SmallObjAllocator { ... }; I want to call this class from the new and delete functions and I would like the class to be static, so I have done this: template<unsigned dummy> struct My_SmallObjectAllocatorImpl { static SmallObjAllocator myAlloc; }; template<unsigned dummy> SmallObjAllocator My_SmallObjectAllocatorImpl<dummy>::myAlloc(DEFAULT_CHUNK_SIZE, MAX_OBJ_SIZE); typedef My_SmallObjectAllocatorImpl<0> My_SmallObjectAllocator; and in the cpp file it looks like this: allocator.cc void* operator new(std::size_t size) { std::cout << "using my new" << std::endl; if(size > MAX_OBJ_SIZE) return malloc(size); else return My_SmallObjectAllocator::myAlloc.allocate(size); } void operator delete(void *p, std::size_t size) { if(size > MAX_OBJ_SIZE) free(p); else My_SmallObjectAllocator::myAlloc.deallocate(p, size); } The problem is when I try to call the constructor for the class SmallObjAllocator which is a static object. For some reason the compiler are calling my overloaded function new when initializing it. So it then tries to use My_SmallObjectAllocator::myAlloc.deallocate(p, size); which is not defined so the program crashes. So why are the compiler calling new when I define a static object? and how can I solve it?

  • How to do a join with ttwo tables ??

    - by bahamut100
    HI, I try to translate this query : SELECT * FROM `reunion` , lieu WHERE reunion.lieu_reunion = lieu.id_lieu to propel query : $c=new Criteria(); $c->addJoin(ReunionPeer::LIEU_REUNION,LieuPeer::ID_LIEU, Criteria::LEFT_JOIN); $this->reunions = ReunionPeer::doSelect($c); But in my template, when I made a print_r($reunions), the field "ville" (from the table 'lieu') is not present. Why ??

  • Adding fields to user registration in Mediawiki

    - by boogie
    Hi, I've been Googling a lot, but I just can't figure out how to add a couple fields to user registration. By default Mediawiki only asks for username, password and real name. I noticed that form is a template under /includes/templates/UserLogin.php, but I don't want to modify that file to make the changes. What is the correct way to do that?

  • Django context processor gets AnonymousUser

    - by myfreeweb
    instead of User. def myview(request): return render_to_response('tmpl.html', {'user': User.objects.get(id=1}) works fine and passes User to template. But def myview(request): return render_to_response('tmpl.html', {}, context_instance=RequestContext(request)) with a context processor def user(request): from django.contrib.auth.models import User return {'user': User.objects.get(id=1)} passes AnonymousUser, so I can't get the variables I need :( What's wrong?

  • Why do we have reinterpret_cast in C++ when two chained static_cast can do it's job?

    - by Nawaz
    Say I want to cast A* to char* and vice-versa, we have two choices (I mean, many of us think we've two choices, because both seems to work! Hence the confusion!): struct A { int age; char name[128]; }; A a; char *buffer = static_cast<char*>(static_cast<void*>(&a)); //choice 1 char *buffer = reinterpret_cast<char*>(&a); //choice 2 Both work fine. //convert back A *pA = static_cast<A*>(static_cast<void*>(buffer)); //choice 1 A *pA = reinterpret_cast<A*>(buffer); //choice 2 Even this works fine! So why do we have reinterpret_cast in C++ when two chained static_cast can do it's job? Some of you might think this topic is a duplicate of the previous topics such as listed at the bottom of this post, but it's not. Those topics discuss only theoretically, but none of them gives even a single example demonstrating why reintepret_cast is really needed, and two static_cast would surely fail. I agree, one static_cast would fail. But how about two? If the syntax of two chained static_cast looks cumbersome, then we can write a function template to make it more programmer-friendly: template<class To, class From> To any_cast(From v) { return static_cast<To>(static_cast<void*>(v)); } And then we can use this, as: char *buffer = any_cast<char*>(&a); //choice 1 char *buffer = reinterpret_cast<char*>(&a); //choice 2 //convert back A *pA = any_cast<A*>(buffer); //choice 1 A *pA = reinterpret_cast<A*>(buffer); //choice 2 Also, see this situation where any_cast can be useful: Proper casting for fstream read and write member functions. So my question basically is, Why do we have reinterpret_cast in C++? Please show me even a single example where two chained static_cast would surely fail to do the same job? Which cast to use; static_cast or reinterpret_cast? Cast from Void* to TYPE* : static_cast or reinterpret_cast

  • Any way to add tabbed forms in django administration site ?

    - by tomjerry
    When using Django "out-of-the-box" administration forms, the "change form" pages can be rather long for complex models (with a lot of fields). I would like to use tabs in the "change form", so things can be more readable (group fields by tabs...) Instead of doing it all by myself, by modifiying the 'change_form.html' admin template, I was wondering whether somebody has already done that and would like to share the code, or whether an existing Django-plugin already exist. Thanks in advance for you answer

  • Can multiple wordpress's feed off one database?

    - by ThomasReggi
    I am a template designer and I want to create one wordpress with all generic posts, but I don't want to have to keep logging in and copy & pasteing the same wordpress posts everytime. Can I point multiple WP installs to one database? A harder way would be export a master db and importing it to each install. Before I go crazy and try to hack something together, does anyone have any advise? -Thanks in advance.

  • Typed metaprogramming languages

    - by Jacques Carette
    I want to do some metaprogramming in a statically typed language, where both my programs and my meta-programs will be typed. I mean this in a strong sense: if my program generator compiles, I want the type system to be strong enough that only type-correct programs can be generated. As far as I know, only metaocaml can do this. (No, neither Template Haskell nor C++ templates fit the bill -- see this paper).
