javascript - Ember.js: How to observe when a value in an input field changes -

-

i need create simple html input text field in ember.js app. value particular input box not bound specific model. when input text box blurs or loses focus, need able run javascript. in template, have far:

{{input valuebinding="pitchersalary" placeholder=0}}

i tried observing value of pitchersalary doing following in controller without luck:

myapp.optimalcontroller = ember.objectcontroller.extend({  pitchersalaryobserver: function () {     var self = this;     console.log("changing....");   }.observes('pitchersalary'),  });

what's correct way of doing this?

you isn't backed model, yet controller saying it's backed model. it's you're confusing ember, wants save model, should backing controller, finds no model. objectcontroller proxies properties to/from controller model, , when has no model, yells misuse.

bad: objectcontroller without model

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...
