javascript - Preserving back button in angular through a loading controller? -

-

depending on logic in services, route different views. facilitate service injection, use loading controller determine go next.

this works great, except can't go "back" through loading controller. how either detect button, or fix loading model more friendly it?

    .when('/loading', {                 templateurl: '/app/views/mystuff/loading.html',                 controller: 'loadingcontroller'             })  angular.module('app').controller('loadingcontroller', ['$location', 'whereservice',     function ($location, whereservice) {         if (!whereservice.donewitha()) {             $location.path('/a');         }         else if (!whereservice.donewithb()) {             $location.path('/b');         }         else {             location.href = "/myapp/somewhereelseentirely"//this fine         }     }]);  angular.module('app').controller('aloadingcontroller', ['$location', 'aservice',     function ($location, aservice) {         if (!aservice.isdone()) {             $location.path(aservice.currentpath());         }         else {             $location.path('/');//triggers loading controller above         }     }]);

sounds need $location.replace():

if called, changes $location during current $digest replacing current history record, instead of adding new one.

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...

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
