angularjs - Angular JS Templating -


i have template set view pages load using 

app.route('/*').get(core.renderindex);

where , renderindex function looks 

exports.renderindex = function (req, res) {   res.render('modules/core/server/views/index', {     user: req.user || null   }); };

now when route has announcement in render different template , not index.server.view.html 

app.route('/:shopid/:locationid/announcement/*').get(core.renderannouncement);    exports.renderannouncement = function (req, res) {       res.render('modules/core/server/views/announcement', {     user: req.user || null,   }); };

the reason why i'am doing because need change meta tags on page i.e. need set variables on view before page renders comes controller.

my question how can access variables in server.view.html file?

<!doctype html> <html lang="en" ng-controller="offercontroller"  ng-init="getannouncement()"> <head>   <meta charset="utf-8">   <meta http-equiv="x-ua-compatible" content="ie=edge,chrome=1">   <meta name="viewport" content="width=device-width,initial-scale=1,maximum-scale=1">   <base href="/">   <title>{{ gettitle }}</title>

like gettitle setting getannouncement method of offercontroller.

this works if set different announcement.client.view.html file , in server file extend it

in case stuck , needs here how did 

 app.get('/:shopid/:locationid/announcement/*',function(req,res,next){     async.waterfall([       function (done) {         var resultsobj = '';           var httptransport = 'http://';         if (config.secure && config.secure.ssl === true) {           httptransport = 'https://';         }          var url = httptransport + req.headers.host+'/api/offer/getbyid/'+req.params[0];         request.get(url, function (err, res, body) {           resultsobj = json.parse(body);           done(err, resultsobj);         });         },       function (resultsobj, done) {         var httptransport = 'http://';          if (config.secure && config.secure.ssl === true) {           httptransport = 'https://';         }          var url = httptransport + req.headers.host+'/api/shops/'+req.params.shopid+'/'+req.params.locationid;            request.get(url, function (err, res, body) {           var resultsobjnew='';                resultsobjnew = json.parse(body);           done(err, resultsobjnew,resultsobj);         });        },       function (resultsobjnew,resultsobj, done) {          res.render('modules/core/server/views/announcement', {           title: resultsobj[0].title,           imageurl  : resultsobj[0].imageurl,           desc : resultsobj[0].desc,           link:resultsobj[0].redirectlink,           logolink: resultsobjnew.logolink,              backgroundimage:resultsobjnew.backgroundimage             });          }         ]);   });

where 

  var request = require('request');    var async = require('async');    var path = require('path');

elasticsearch - Is the order of operations guaranteed in a bulk update? -

i sending delete , index requests elasticsearch in bulk (the example adapted from docs ): { "delete" : { "_index" : "test", "_type" : "type1", "_id" : "1" } } { "index" : { "_index" : "test", "_type" : "type1", "_id" : "1" } } { "field1" : "value1" } the sequence above intended first delete possible document _id=1 , index new document same _id=1 . is order of actions guaranteed? in other words, example above, can sure delete not touch document index ed afterwards (because order not respected reason or another)? the delete operation useless in scenario, if index document same id, automatically , implicitly delete/replace previous document same id. so if document id=1 exists, sending below command replace (read delete , re-index it) { "index" : { "_index" : "test", ...
