如果我创建一个新的电影对象，则不会显示来自所有者 (App.User) 的关联用户名。它仅在我重新加载页面后显示。知道如何在创建新电影后立即显示关联的用户名吗？
到目前为止的代码：
App.Movie = Ember.Model.extend({
objectId: Ember.attr(),
title: Ember.attr(),
year: Ember.attr(),
owner: Ember.belongsTo('App.User', {
key: 'owner',
serializer: UserType
})
});
App.User = Ember.Model.extend({
objectId: Ember.attr(),
username: Ember.attr(),
});
App.Movie.adapter = Ember.Adapter.create({
createRecord: function(record) {
return Ember.$.ajax({
headers: {
'X-Parse-Application-Id': '',
'X-Parse-REST-API-Key': ''
},
type: 'POST',
url: 'https://api.parse.com/1/classes/Movie',
contentType: 'application/json',
data: JSON.stringify(record)
}).then(function(data) {
record.load(data.objectId, record.get('_data'));
record.didCreateRecord();
});
}
});
{{#each movie in this}}
<tr>
<td>{{movie.year}}</td>
<td>{{movie.title}}</td>
<td>{{movie.owner.username}}</td>
</tr>
{{/each}}
App.MoviesIndexController = Ember.ArrayController.extend({
rawDescription: '',
year: '',
title: '',
errors: null,
actions: {
createMovie: function () {
var rawDescription = this.get('rawDescription');
if (!rawDescription.match(/([^$]+)(\d{4})/)) {
this.set('errors', {
rawDescription: 'Oh snap! Please include the movie\'s title and year.'
});
} else if (!this.isUnique({
rawDescription: rawDescription
})) {
this.set('errors', {
rawDescription: 'Oh snap! The movie already exists.'
});
} else {
var rv = this.parseRawDescription(this.get('rawDescription')),
title = rv[1],
year = rv[2],
newMovie = App.Movie.create({
owner: App.Session.authUser,
ratings: [{ objectId: App.Session.objectId, value: 0 }]
title: title,
watched: false,
year: year,
});
newMovie.save();
this.setProperties({ rawDescription: '', errors: null });
}
}
}
});
