我可能正在做这个可怕的错误,但是这里是:我从服务器获取用户,一旦解决了,我试图将用户的名称呈现给页面。登录表单实际上是一个基于此的弹出窗口:http://www.sociallipstick.com/?p=86
不幸的是,当我将userLoggedIn
设置为true
时,模板根本不会改变。我做错了吗?
App.UserController = Ember.Controller.extend({
userLoggedIn: false,
actions: {
displayLoginForm: function () {
//displays a login form
},
recieveLogin: function (authResult) {
//hides login form
var userPromise = this.store.find('user', authResult); // successfully gets user from server (as far as I can tell)
var self = this;
userPromise.then(function (user) {
self.set('model', user);
self.set('userLoggedIn', true);
});
}
}
});
<li class="navbar-form">
{{#if userLoggedIn}}
<a href="#" class="dropdown-toggle" data-toggle="dropdown"><b class="caret"></b></a>
<ul class="dropdown-menu">
<li><a href="#">My quizzes</a></li>
<li><a href="#">My scores</a></li>
<li><a href="#">Settings</a></li>
<li class="divider"></li>
<li><a href="#">Logout</a></li>
</ul>
{{else}}
<button class="btn btn-default" {{action 'displayLoginForm'}}>Login</button>
{{/if}}
</li>
答案 0 :(得分:0)
这个错误实际上是由一个完全不同的问题引起的。登录脚本的回调使用[hacky]行从Ember外部的弹出窗口获取控制器:
window.opener.App.__container__.lookup('controller:User').send('recieveLogin', 'USERIDHERE');
不幸的是,这实际上得到了一个不同的控制器实例......
所以,我修改了控制器:
App.UserController = Ember.Controller.extend({
userLoggedIn: false,
actions: {
displayLoginForm: function () {
//displays a login form
/******** THIS IS THE IMPORTANT LINE ********/
App.UserController.callback = this;
/******** THAT WAS THE IMPORTANT LINE ********/
},
recieveLogin: function (authResult) {
//hides login form
var userPromise = this.store.find('user', authResult); // successfully gets user from server (as far as I can tell)
var self = this;
userPromise.then(function (user) {
self.set('model', user);
self.set('userLoggedIn', true);
});
}
}
});
然后我在页面上使用了稍微不那么粗俗的一行:
window.opener.App.UserController.callback.send('recieveLogin', 'USERIDHERE');
