Ember模型未更新

我有一個顯示挑戰列表的路線，當我創建新的挑戰時，記錄被保留，但是當我轉換回路線時，挑戰列表的模型不會更新。有什麼我失蹤？Ember模型未更新

//new.js 
var challenge = this.store.createRecord('challenge', { 
      name_en: this.get('model.name_en'), 
      name_fr: this.get('model.name_fr'), 
      description_en: this.get('model.description_en'), 
      description_fr: this.get('model.description_fr'), 
      end_date: this.get('model.end_date'), 
      start_date: this.get('model.start_date'), 
      points_cap: this.get('model.points_cap'), 
      points_goal: this.get('model.points_goal'), 
      challenge_type: 1, 
      short_description_en: this.get('model.short_description_en'), 
      short_description_fr: this.get('model.short_description_fr'), 
      excluded_activities: excluded 
     }); 

     // Persist record. 
     challenge.save().then((challenge) => { 
      this.transitionToRoute('challenges'); 
     }).catch((error) => { 
      this.handleError(error, 'error.system_error'); 
     }); 

//router.js 
Router.map(function() { 
    this.route('challenges', function() { 
    this.route('new'); 
    this.route('challenge', { 
    path: ':challenge_id' 
}, function() { 
    this.route('delete'); 
    this.route('edit'); 
});

}）;

//challenges.js 
import Ember from 'ember'; 
import AuthenticatedRouteMixin from 'simple-auth/mixins/authenticated-route-mixin'; 
import UserProfile from '../models/user-profile'; 

export default Ember.Route.extend(AuthenticatedRouteMixin,{ 

userProfile: UserProfile.create(), 

model: function() { 
    return this.store.query('challenge', {league_id: this.get('userProfile.league_id')}); 
}

}）;

//new challenge payload 
{ 
"activity_exclusion_list":[ 

], 
"challenge_type":1, 
"challengeUrl":null, 
"end_date":"31-10-2015", 
"number_participants":null, 
"number_teams":null, 
"points_cap":null, 
"points_goal":null,

"name_lang":{ 
    "en":"New Challenge ", 
    "fr":null 
}, 
"description_lang":{ 
    "en":"New Challenge", 
    "fr":null 
}, 
"short_description_lang":{ 
    "en":"New Challenge", 
    "fr":null 
}

}

//response from new challenge 
{ 
"challenge_type":"Individual", 
"description":" ", 
"description_fr":null, 
"description_lang":{ 
    "en":"New Challenge", 
    "fr":null 
}, 
"challengeUrl":" ", 
"start_date":"01-10-2015",

乍一看似乎沒問題。你可以提供你的挑戰路線，看看你是如何檢索模型？ –

當然你在這裏 – jpoiri

我假設你正在使用'this.store.query'因爲'league_id'不是你的主體id，對吧？那麼在你的'createRecord'中，你在哪裏設置'league_id'？ –

在你的挑戰路線你嘗試過使用this.store.filter呢？問題可能是查詢函數只返回一個RecordArray，而過濾器返回一個Live RecordArray，它會在承諾（在這種情況下是成功保存）解析後更新模板和其他所有內容。

model: function() { 
    return this.store.filter('challenge', {league_id: this.get('userProfile.league_id')}, function() { 
     // We're not actually filtering, so just return true for everything 
     return true; 
    }); 
}

我有同樣的問題，這原來是解決方案，希望它有幫助！
