Assuming you haven’t set TEMPLATE_CONTEXT_PROCESSORS to some other value in settings.py, Django will automatically load the debug context preprocessor (as noted here). This means that you will have access to a variable called debug in your templates if settings.DEBUG is true and your local machine’s IP address (which can simply be 127.0.0.1) is set in … Read more
You’d do this by creating your own HTML helper. http://www.asp.net/mvc/tutorials/creating-custom-html-helpers-cs You can view the code for LabelFor<> by downloading the source for ASP.Net MVC and modify that as a custom helper. Answer added by balexandre public static class LabelExtensions { public static MvcHtmlString LabelFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression, object htmlAttributes) { return LabelFor(html, … Read more

This is of course invalid as per HTML4.01. META tags are only allowed within HEAD (just like, say, TITLE) so by putting it into a BODY, you’re essentially creating an invalid markup. From the cursory tests, it seems that some browsers (e.g. Firefox 3.5 and Safari 4) actually put these elements into HEAD when creating … Read more

Option 1: You can use view::share() like so: <?php namespace App\Http\Controllers; use View; //You can create a BaseController: class BaseController extends Controller { public $variable1 = “I am Data”; public function __construct() { $variable2 = “I am Data 2”; View::share ( ‘variable1’, $this->variable1 ); View::share ( ‘variable2’, $variable2 ); View::share ( ‘variable3’, ‘I am Data … Read more
Another way is as follows. If one has a list of tuples say: mylst = [(a, b, c), (x, y, z), (l, m, n)] then one can unpack this list in the template file in the following manner. In my case I had a list of tuples which contained the URL, title, and summary of … Read more
Your desire not to modify t is expressed in const T& t. The ending const specifies that you will not modify any member variable of the class abs belongs to. Since there is no class where this function belongs to, you get an error.

Use @tparam for template arguments, @arg for function arguments. For return values, @return. There is no return here. There are just typedefs. BTW, your sample code doesn’t look like a metafunction. Metafunctions are hairy beasts that take advantage of SFINAE to do something that C++ wasn’t originally intended to do (e.g., reflection). Your generate_callback_map just … Read more
