ember.js - EmberJS Model find not up-to-date with underlying store -

-

for simple overview screen have developed route sets controller app.location.find(). 

app.locationsindexroute = ember.route.extend({    setupcontroller: function(controller) {     controller.set('content', app.location.find());   },    rendertemplate: function() {     this.render('locations.index',{into:'application'});   }  });

i naively assumed go store , fetch me records, giving me up-to-date view of records.

apparently not....

  • when external process starts removing records database, app.location.find() keeps on returning these deleted records. (although rest call doesn't show them anymore)
  • if external process starts adding records database, app.location.find() picks them up.
  • if delete records form within ember app model correctly updated.

how should deal in ember app ? i'd have up-to-date view on whatever in database. right need refresh page (f5) date view. using linkto helpers shows me stale data.

this seems yet trivial thing missed in emberjs. somewhere mentioned in docs why behaves ? guess there valid philosophy behind behavior.

my overview screens interested in showing up-to-date data. if record no longer in db model should not return anymore.

i've added sample project in github having issues.

try unloading of data store before call find():

this.store.unloadall('widget'); this.store.find('widget');

that refresh store reflect what's on server.

c++ - Function signature as a function template parameter -

-
i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...

-
there's function on page want call after loads. not own page, can't insert html it. can please provide specific examples how chrome extension or greasemonkey?
