javascript - Meteor: How to detect if users authenticated -

-

in app use accounts-github. works perfect, have 1 problem.

in 1 of templates do

template.bar.rendered = function () {     if (meteor.user()) {         // setup stuff     } }

the problem if user not logged in code not executed (thats ok). when user authenticates code not executed again. question how can listen change inside template (doesn't have in inside rendered function!)?

you use deps.autorun. (http://docs.meteor.com/#deps_autorun)

usually deps.autorun run whole meteor app. if want make runs per template need create , stop in rendered , destroyed template callbacks

e.g

var loginrun;  template.bar.rendered = function() {     loginrun = deps.autorun(function() {         if(meteor.user()) {             //stuff run when logged in         }     }); }  template.bar.destroyed = function() {     loginrun.stop(); }

if don't need run per template (need run once app on template, can use deps.autorun on own, anywhere in client side code.

meteor.user() reactive, ensure deps.autorun callback runs again when changes, theoretically use things when user logs in or out.

other alternatives there package on atmosphere provides login , logout hooks, though use deps.autorun above work anyway. see https://github.com/benjaminrh/meteor-event-hooks

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
