ember.js - Trigger Ember Error Substate in Route Action -

-

let's have banananewroute that's responsible displaying new banana form , creating banana.

app.banananewroute = ember.route.extend   model: -> @store.createrecord('banana')    actions:         create: @currentmodel.save().then => @transitionto "banana", @currentmodel

because input of application tightly controlled, it's safe assume if server returns type of error, it's application error , there's nothing user can it. i'd handle transitioning user separate error template whenever save action rejects.

i took @ loading / error substates documentation, seems works model, beforemodel , aftermodel hooks. couldn't work create action. how can accomplish this?

save returns promise. promise's takes both passing , failing function (pardon converted coffeescript).

save().then ((results) ->   console.log "it worked", results   return ), (error) ->   console.log "it failed", error   return

or in javascript, , breaking down bit

var pass = function(results){}; var fail = function(error){};  save().then(pass, fail);

to manually transitionto error route, need call 

this.transitionto('error', reason);

example http://emberjs.jsbin.com/xetatoxo/1/edit

the same can done deeper error routes

this.transitionto('foo.error', 'it died');

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...
