    - by aaandre
    get '/stylesheets/style.css' do header 'Content-Type' => 'text/css; charset=utf-8' sass :style end does not produce the stylesheet anymore. What would be a version 1.0 compatible way to do this? Or, troubleshooting suggestions if you think that the issue is with the code? The style.sass file is in the /views folder. Haml files from the same folder render OK. Thank you.

  • wordpress custom post type

    - by codedude
    So I've just made a custom post type for my wordpress theme named "Products". When I create a new post in it and view it, the link is something like this: "http://localhost/wordpress/product/a-product-title" This page views as expected but when I try to go to the supposed parent page: "http://localhost/wordpress/product/" I get a 404 error page. Is there a special template I need to make to view this page? Thanks

  • ASP.NET MVC: MetaTags; setting methodology, best practices

    - by MVCDummy09
    When I created a default MVC application in VS2K10, the master view (Site.Master) had a ContentPlaceHolder for the <title> tag. Is there a better way to set metatags like title and description than using a ContentPlaceHolder in the master and setting that ContentPlaceHolder's value in each view? How do you configure your views' metatags in a large-scale site with dozens and dozens of pages?

    - by Matt
    Beginner question here. I'm going to make a Jquery function that is used to change an image when hovering over it. I use the id name as the selector. How do I make it generic so that I don't have to have a copy of the function for every single tag with a rollover image? $("#home img").hover( function(){ blah }, function(){ blah } );

  • Asp.net mvc, entity framework, Poco - Architecture

    - by user1576228
    I have a "small" enterprise application, aspnet mvc 3 + entity framework with POCO entity and repository pattern. I structured the solution in 4 projects: POCO entities Domain model Services web application When the application performs a query on the database, use one of the services provided, the service uses the repository and the small classes, as a result I have some dynamic proxy objects that I would like to convert in my domain entities, before using them in mvc views, but I do not know how. Dovrebber be set as the translator? This approach is reasonable?

  • Nested generator functions in python

    - by Yuval A
    Consider a tuple v = (a,b,c) and a generator function generate(x) which receives an item from the tuple and generates several options for each item. What is the pythonic way of generating a set of all the possible combinations of the result of generate(x) on each item in the tuple? I could do this: v = (a,b,c) for d in generate(v[0]): for e in generate(v[1]): for f in generate(v[2]): print d,e,f but that's just ugly, plus I need a generic solution.

  • Java class object from type variable

    - by Alexander Temerev
    Is there a way to get Class object from the type variable in Java generic class? Something like that: public class Bar extends Foo<T> { public Class getParameterClass() { return T.class; // doesn't compile } } This type information is available at compile time and therefore should not be affected by type erasure, so, theoretically, there should be a way to accomplish this. Does it exist?

  • iPhone SDK reload UIView's content

    - by Matt S.
    I have two views, one view takes the whole screen, the second view covers only a little portion. What I want is for that second view to be on the first view (which I already have done), but the problem is, when I set values (in this case UILabel's) the label on the screen doesn't display that new value. I know for a fact the method gets called, but for some reason it won't change the label's value.

  • Unit Test json output in Zend Framework

    - by lyle
    The Zend Tutorial lists many assertions to check the output generated by a request. http://framework.zend.com/manual/en/zend.test.phpunit.html But they all seem to assume that the output is html. I need to test json output instead. Are there any assertions helpful to check json, or is there at least a generic way to make assertions against the output? Anything that doesn't rely on the request outputting html?
