Laravel dynamic page title in navbar-brand

由 筅森魡賤 提交于 2019-12-21 04:05:22
问题 I have layouts.app.blade.php where I have my <html> and <body> tags and also the <nav> . In the <body> I yield content for every page, so they basically extend this app.blade.php. All basic Laravel stuff so now I have this: <div class="navbar-header"> <!-- Collapsed Hamburger --> <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#spark-navbar-collapse"> <span class="sr-only">Toggle Navigation</span> <span class="icon-bar"></span> <span class="icon-bar">

Why isn't XmlDocument dynamic in .NET 4?

由 ￡可爱￡侵袭症＋ 提交于 2019-12-21 04:02:19
问题 One of the areas where I would like to see the use of dynamic is XML. I think it would make XML processing code simpler to write and I believe I saw some examples on that before C# 4 came out and it's mentioned in this answer as one of the uses of this feature. So, my question is this: why wasn't the XmlDocument (or XDocument ) made dynamic, or why isn't there some new class for dynamic XML manipulation in C# 4? This is even more strange to me, when I consider that in PowerShell, XmlDocument

Passing build parameters to .wxs file to dynamically build wix installers

由 给你一囗甜甜゛ 提交于 2019-12-21 03:54:19
问题 I am a student developer and I have built several installers for the company I am working with now. So I am fairly familiar with WIX. We recently decided to have a Build server that auto builds our solution. It builds both debug, and release, as well as Obfuscated (and non obfuscated) projects. And you really don't have to understand any of this. All you have to understand is that I have the same Wix project building different MSIs dynamically. So the way we build them is we call MSBuild.exe

What does it mean that JavaScript is “dynamic”?

由 主宰稳场 提交于 2019-12-21 03:18:18
问题 I've read from different sources (e.g. wiki, articles, etc.) what dynamic in a programming sense means. Wikipedia talks about how dynamic programming languages execute certain programming behaviors at runtime (as opposed to compile time for static languages), but their explanation is vague and talks about how these behaviors vary in degree of difficulty, complexity, and performance costs for all programming languages. So with respect to JavaScript specifically, what does it mean that it's

Iteratively forecasting dyn models

由 五迷三道 提交于 2019-12-21 03:10:11
问题 I've written a function to iteratively forecast models built using the package dyn, and I'd like some feedback on it. Is there a better way to do this? Has someone written canonical "forecast" methods for the dyn class (or dynlm class), or am I venturing into uncharted territory here? ipredict <-function(model, newdata, interval = "none", level = 0.95, na.action = na.pass, weights = 1) { P<-predict(model,newdata=newdata,interval=interval, level=level,na.action=na.action,weights=weights) for

How does ViewBag in ASP.NET MVC work behind the scenes?

由 ∥☆過路亽．° 提交于 2019-12-21 03:09:13
问题 I am reading a book on ASP.NET MVC and I'm wondering how the following example works: Example #1 Controller public class MyController : Controller { public ActionResult Index() { ViewBag.MyProperty = 5; return View(); } } View <h1>@ViewBag.MyProperty</h1> Now I understand that ViewBag is a dynamic object, so that's how you can set the property (though I don't know much about dynamic objects, never worked with them.) But how does the view get the specific instance of the ViewBag from the

dlopen vs linking overhead

由 点点圈 提交于 2019-12-21 02:52:15
问题 Suppose I have a library - foo.so . When building my binary (which needs this library), I can either (1) link foo.so , or, (2) within the program source code, dlopen this library and then call functions provided by this library Is there any performance difference between (1) and (2) when I call a function from the library? Note that I am aware that there will be different initialization characteristics (like the cost of the dlopen , overhead for first usage of a symbol etc) but in the steady

Generate a `link_to` to the controller action `edit`, dynamically

由 戏子无情 提交于 2019-12-21 01:06:15
问题 I am using Ruby on Rails 3.0.7 and I would like to generate a link_to to the controller action edit , dynamically . I have to use it in a partial template but the issue is that I am rendering that same partial template for different model data (that is, I pass local variables of different class instances in that). So I can not use the route "magical RoR way" `edit_<singular_name_of_the_resource>_path(<resource_class_instance>)`. I would like to make something like the following: link_to(
