ruby on rails - The Asset pipeline doesn't use the fingerprinted routes for the images after precompile -

-

i'm loading background image bg.jpg image in scss file, style.css.scss

background: url(/assets/bg.jpg)  no-repeat center center;

after precompilation, sprockets places copy of image in /public/assets directory fingerprinted name bg-28779d74f8a6fc51d1b46376428bed54.jpg . , can access image browser @ /assets/bg-28779d74f8a6fc51d1b46376428bed54.jpg link.

but when reaload page in browser, background image not displayed , when check css in dev tools particular element see: 

background: url(/assets/bg.jpg) no-repeat center center;

shouldn't 

background: url(/assets/bg-28779d74f8a6fc51d1b46376428bed54.jpg ) no-repeat center center;

le: i precompile assets rake assets:precompile having rails_env set production. thought idea mention since noticed many other people had problems because of this. sass-rails helpers "image-url", "asset-url" not working in rails 3.2.1

the correct answer in comments, here is:

image urls in stylesheets (that point images in asset pipeline) should use sass helper image-url("bg.jpg") instead of url('/assets/bg.jpg')

this helper uses asset pipeline find correct path name each image.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
