javascript - How to test an Ember model's computed property that has relations dependencies? -

-

i'm writing qunit tests test ember model, having hard time testing computed properties have relation dependency (the computed property triggers model's computed property).

the model testing (coffeescript):

customer = ds.model.extend   firstname:      ds.attr('string')   lastname:       ds.attr('string')   phones:         ds.attr('embedded-list') phone: (->     @get('phones.firstobject.number')   ).property('phones.firstobject.number')  fullname: (->     [@get('lastname'), @get('firstname')].join(' ') )   ).property('firstname','lastname')

the meeting model:

meeting = ds.model.extend   customers: ds.hasmany('customer')    startat:   ds.attr('isodate')   status:    ds.attr()   objective: ds.attr()   customerphones: (->     phones = []     @get('customers').foreach (c) ->       c.get('phones').foreach (ph) ->         phones.push(ph.number)     phones   ).property('customers.@each.phones')     firstcustomer: (->     @get('customers.firstobject')   ).property('customers.firstobject')   firstcustomerfullname: (->     @get('firstcustomer.fullname')   ).property('firstcustomer.fullname')

now, testing customerphones, , firstcustomerfullname giving me real hard time...

my test looks follows:

`import { test, moduleformodel } 'ember-qunit';`  moduleformodel('meeting', 'app.meeting',{    needs: ['model:customer']    setup: ->      ember.run (t = @)->        ->         customer = t.store().createrecord 'customer', firstname: 'john', lastname: 'smith', phones:[]         customer.get('phones').addobject(ember.object.create({tag: 'home', number: '111222333'}))         customer.get('phones').addobject(ember.object.create({tag: 'work', number: '444555666'}))          t.subject().set('customers.content', ember.arrayproxy.create({content: []}));         t.subject().get('customers.content').pushobject(customer)      teardown: ->   },(container, context) ->       container.register 'store:main', ds.store       container.register 'adapter:application', ds.fixtureadapter       context.__setup_properties__.store = -> container.lookup('store:main') )  test "it's ds.model", -> ok(@subject())  test "attributes: can created valid values", ->   meeting = @subject({objective: 'follow up'})   ember.run ->     equal(meeting.get('objective', 'follow up'))   test "properties: firstcustomer & firstcustomerfullname & firstcustomerphone", ->   meeting = @subject()   ember.run ->     equal(meeting.get('firstcustomer.fullname'),  'smith john')     equal(meeting.get('firstcustomer.phone'),     '111222333')

now, used techniques in test, found in answer here on stack overflow, can't seem find now.

that worked few days ago, (it seems nonsense know) whenever run test, errors:

assertion failed: cannot add 'meeting' records relationship (only 'meeting' allowed)

i don't know error is, nor how fix it. spent day monkeying around, no outcome.

how can resolve this?

okay, have far comment, i'm going wip answer.

  • i removed of run loops, necessary async processes.

  • i changed of computed properties computed.alias properties

i.e.

phone: (->   @get('phones.firstobject.number') ).property('phones.firstobject.number')

to

phone: ember.computed.alias('phones.firstobject.number')
  • i ripped out of setup, ember data eagerly loads store on own , use fixture ids etc without specifying it. (this part can put it, isn't necessary in context).

i.e.

  },(container, context) ->   container.register 'store:main', ds.store   container.register 'adapter:application', ds.fixtureadapter   context.__setup_properties__.store = -> container.lookup('store:main')
  • and apologize in advance, i'm not fan of coffeescript, put in js. question is, if you're still seeing issues may need find out versions of ember, ed, , ember qunit using.

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...
