iron router - Meteor - How do I automatically redirect user to page when data changes -


i writing meteor app takes in external data machine (think iot) , displays lots of charts, graphs, etc. far good. there various pages in application (one per graph type far). data being fed in "real-time", there situation (normal) data "set" gets totally reset. i.e. data no longer valid. when happens, want redirect user "home" page regardless of (well, except home page).

i hoping make "global" item, don't want overhead. noticed iron:router (that using) has ondata()method seems bit -- high overhead -- since it's 1 piece of data indicates reset.

since each page rather "independent" , user can stay on page long time (the graphs auto-update underlying data changes) , i'm not sure iron:router best approach @ all.

this meteor 1.0.x btw.

just looking clean "proper" meteor way handle this. put check in redisplay logic of each page, think more abstracted (read: global) approach more long-term friendly (so if add more pages of graphs automatically still works) ..

thanks!

this job cursor.observechanges http://docs.meteor.com/#/full/observe_changes set collection servers "reset notification" broadcasts users when new notification inserted.

on client:

criteria = {somecriteria: true}; query = resetnotificationcollection.find(criteria) var handle = query.observechanges({   added: function (id, user) {     router.go('home');   } });

whenever reset happens:

notification = { time: new date(), whateveryouwanthere: 'useful info' } resetnotificationcollection.insert notification

on insert, clients observing changes on collection respond efficient little ddp message.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
