Question

我正在尝试检查Model是否包含在模型集合中，但即使集合包含我的搜索模型，包含检查仍然失败（myFriendshipStatus）：

    var attr = DS.attr;

GambifyApp.User = DS.Model.extend({
    firstName: attr(),
    lastName: attr(),
    nickName: attr(),
    image: attr(),

    friendsWithMe: DS.hasMany('user', {
        inverse: 'myFriends', async: true
    }),
    myFriends: DS.hasMany('user',{
        inverse: 'friendsWithMe', async: true
    }),
    groups: DS.hasMany('group', {async: true}),

    fullName: function() {
        return this.get('firstName') + ' ' + this.get('lastName');
    }.property('firstName', 'lastName'),

// Ember.computed.intersect('myFriends', 'friendsWithMe')
    friends: function() {
        var ret = [];
        Ember.RSVP.all([this.get('myFriends'), this.get('friendsWithMe')]).then(function(results) {
            ret.pushObjects(_.intersection(results[0].get('content'), results[1].get('content'))) ;
        });
        return ret;
    }.property('myFriends', 'friendsWithMe'),


    /**
     *  Gives the relation between two User
     *  4: has requested your friendship
     *  3: Yourself
     *  2: Friends
     *  1: FriendShip Request
     */
    myFriendshipStatus: function() {
    if(this.get('friends').contains(GambifyApp.User.Current)){
        return 2
    } else if(this.get('friendsWithMe').contains(GambifyApp.User.Current)){
        return 4
    } else if(this.get('myFriends').contains(GambifyApp.User.Current)){
        return 1
    } else if (this.get('id') === GambifyApp.User.Current.id){
        return 3
    } else {
        return 0
    }
    }.property('myFriends', 'friendsWithMe')
});

这些是我正在使用的灯具：

GambifyApp.User.FIXTURES = [
    { id: 1, firstName: 'Marc', lastName: 'Höffl', nickName: 'marc',
        image: 'images/fixtures/Profile/marc.jpg',
        friendsWithMe: [2, 3],
        myFriends: [2, 3],
        groups: [1, 2]
    },
    { id: 2, firstName: 'Tobias' , lastName: 'Degele', nickName: 'degi',
        image: 'images/fixtures/Profile/degi.jpg',
        friendsWithMe: [1, 3, 4, 5],
        myFriends: [1, 3],
        groups: [1, 2]
    },
    { id: 3, firstName: 'Franz' , lastName: 'Herbert', nickName: 'Hubi',
        friendsWithMe: [4],
        myFriends: [1,2, 3,4,5],
        image: 'images/fixtures/Profile/MOF.jpg',
        groups: [1]
    },
    { id: 4, firstName: 'Christian' , lastName: 'Ditter', nickName: 'Dyder',
        friendsWithMe: [3, 5],
        myFriends: [2, 3, 5],
        image: 'images/fixtures/Profile/user.png',
        groups: [ 2]
    },
    { id: 5, firstName: 'Strego' , lastName: 'Pengo', nickName: '!',
        friendsWithMe: [3, 5],
        myFriends: [2, 4, 5],
        image: 'images/fixtures/Profile/diggity.jpg',
        groups: [ 2]
    }

];

这是我当前登录用户的Fixture：

GambifyApp.User.Current = GambifyApp.User.FIXTURES[0]

我已经调试了contains函数，我发现搜索到的模型包含在我的集合中但仍然找不到。

更新我现在已经解决了它，不是通过全局解决方案，而是通过在所有控制器中注入用户：

Ember.Application.initializer({
  name: "currentUser",

  initialize: function(container, application) {
    var store = container.lookup('store:main');

    container.optionsForType('user', { instantiate: false, singleton: true });
    container.register('user:current', store.find('user', 1));
  }
});

Ember.Application.initializer({
  name: "injectCurrentUser",
  after: 'currentUser',

  initialize: function(container) {
    container.injection('controller:application', 'currentUser', 'user:current');
    container.typeInjection('route', 'currentUser', 'user:current');
  }
});

包含告诉您确切的对象是否在那里。 Ember Data使用DS.Model包装夹具数据，并且所有这些都是额外的魔法（脏检查，保存等）。所以POJO不会被发现。

因此，您最好找到记录（使用商店）并分配

GambifyApp.User.Current = this.store.find('user', 1);

Ember数组不包含Fixture
