ember.js - Emberjs Model updates only partially -


i have table component, feed model. if updated data comes server, push payload store, updates model, , table should re-render.

the problem: despite record updated (see different exchange values) re-rendered, iso value different too. discovered there connection between sortproperties array , re-rendered rows. if change sortproperties to

sortproperties: ['name'],

then rows re-rendered, record's name has been updated.

the expected behavior be, if 3 row re-rendered, since 3 record's exchange property changed.

some explanation: sortpropertieswithorders generates string based on asc , sortproperties arrays. string used in multisort, computed.sort property, , multisorting content (the model) of table.

update

i have found solution problem, not flexible @ all: sortpropertieswithorders should observe each element's exchange property in content. since component, content's property unpredictable, , can't hard code in example. working, not optimal jsbin:

(hopefully) last update define sortpropertieswithorders in table component's init. way can build dynamically string of dependent keys it. may find helpful code:

  init: function(){     this._super();     var columns = this.get('columns');     var i=0;     var cps = [];     for(i=0; < columns.length; i++ ){         if (columns[i].property)           cps.push(columns[i].property);     }     var str = 'content.@each.{' + cps.join(',') + '}';       ember.defineproperty(this, 'sortpropertieswithorders',   ember.computed(str, 'sortproperties', 'asc', function(){       var ret = ember.a();       var asc = this.get('asc');       this.get('sortproperties').foreach(function(property, i){          var tmp = asc[i] ? property : property + ':desc';         ret.push(tmp);       });        return ret;     }));   },

and working jsbin:

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
