如果你想象两个模型定义如下：
App.User = DS.Model.extend({
emails: DS.hasMany('email',{embedded: 'always'}),});
App.Email = DS.Model.extend({
address: DS.attr('string'),alias: DS.attr('string'),user: DS.belongsTo('user')
});
…和REST适配器：
App.UserAdapter = DS.RESTAdapter.extend({
url: 'http://whatever.com',namespace: 'api/v1'
});
…路由设置如下：
App.Router.map(function () {
this.route('index',{ path: '/' });
this.resource('users',function () {
this.route('index');
this.route('add');
this.resource('user',{ path: ':user_id' },function () {
this.route('delete');
this.route('edit');
this.resource('emails',function () {
this.route('index');
this.route('add');
this.resource('email',{ path: ':email_id' },function () {
this.route('delete');
this.route('edit');
});
});
});
});
});
…以及用于保存已编辑电子邮件的控制器操作,如下所示：
App.EmailEditController = Ember.ObjectController.extend({
actions: {
save: function () {
var self = this;
var email = this.get('model');
email.save().then(function(){
self.transitionToRoute('email',email);
});
}
}
});
这个问题是……
PUT请求被发送到：http://whatever.com/api/v1/emails/[email_id]
但是,正确的API端点是：http://whatever.com/api/v1/users/[user_id]/emails/[email_id]
解决方法
我想出的解决方案就是在REST适配器中重写createRecord,updateRecord和deleteRecord.
我为受影响的模型添加了“父”属性.在* Record钩子中,我可以检查是否已设置并相应地编辑发送到buildURL的路径.
我的createRecord,updateRecord和deleteRecord挂钩现在看起来类似于：
App.UserAdapter = DS.RESTAdapter.extend({
createRecord: function (store,type,record) {
if (!record.get('parent') || null === record.get('parent')) {
return this._super(store,record);
}
var data = {};
var serializer = store.serializerFor(type.typeKey);
var parent_type = record.get('parent');
var parent_id = record.get(parent_type).get('id');
var child_type = Ember.String.camelize(
Ember.String.pluralize(
type.typeKey.split(
record.get('parent')
).pop()
)
);
var path = Ember.String.pluralize(parent_type) + '/' + parent_id + '/' + child_type;
serializer.serializeIntoHash(data,record,{ includeId: true });
return this.ajax(this.buildURL(path),"POST",{ data: data });
},updateRecord: function(store,record) {
if(!record.get('parent') || null === record.get('parent')){
return this._super(store,record);
var id = record.get('id');
return this.ajax(this.buildURL(path,id),"PUT",deleteRecord: function (store,record) {
if (!record.get('parent')) {
return this._super(store,record);
}
var parent_type = record.get('parent');
var parent_id = record.get('parent_id');
var child_type = Ember.String.camelize(
Ember.String.pluralize(
type.typeKey.split(
record.get('parent')
).pop()
)
);
var path = Ember.String.pluralize(parent_type) + '/' + parent_id + '/' + child_type;
var id = record.get('id');
return this.ajax(this.buildURL(path,"DELETE");
}
});
示例中的电子邮件模型类似于：
App.Email = DS.Model.extend({
address: DS.attr('string'),user: DS.belongsTo('user'),parent: 'user'
});
