问题描述
如果你想象两个这样定义的模型:
If you imagine two models defined thus:
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')
});
... 和一个 REST 适配器:
... and a REST Adapter:
App.UserAdapter = DS.RESTAdapter.extend({
url: 'http://whatever.com',
namespace: 'api/v1'
});
... 路由设置如下:
... with routing set up like so:
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');
});
});
});
});
});
... 以及用于保存编辑的电子邮件的控制器操作,如下所示:
... and a controller action to save the edited email, which looks like this:
App.EmailEditController = Ember.ObjectController.extend({
actions: {
save: function () {
var self = this;
var email = this.get('model');
email.save().then(function(){
self.transitionToRoute('email', email);
});
}
}
});
问题是...
PUT 请求正在发送至:http://whatever.com/api/v1/emails/[email_id]
The PUT request is being sent to: 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]
However the correct API endpoint is: http://whatever.com/api/v1/users/[user_id]/emails/[email_id]
解决此问题的正确方法是什么?
What is the correct way to remedy this issue?
推荐答案
我想出的解决方案只是在 REST 适配器中重写 createRecord、updateRecord 和 deleteRecord.
The solution I came up with was just to rewrite createRecord, updateRecord and deleteRecord in the REST adapter.
我为受影响的模型添加了父"属性.在 *Record 挂钩中,我可以检查是否已设置并相应地编辑发送到 buildURL 的路径.
I added a 'parent' attribute to the models affected. In the *Record hooks, I can check if this is set and edit the path sent to buildURL accordingly.
我的 createRecord、updateRecord 和 deleteRecord 钩子现在看起来类似于:
My createRecord, updateRecord and deleteRecord hooks now looks something similar to this:
App.UserAdapter = DS.RESTAdapter.extend({
createRecord: function (store, type, record) {
if (!record.get('parent') || null === record.get('parent')) {
return this._super(store, type, 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, type, record, { includeId: true });
return this.ajax(this.buildURL(path), "POST", { data: data });
},
updateRecord: function(store, type, record) {
if(!record.get('parent') || null === record.get('parent')){
return this._super(store, type, 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, type, record);
var id = record.get('id');
return this.ajax(this.buildURL(path, id), "PUT", { data: data });
},
deleteRecord: function (store, type, record) {
if (!record.get('parent')) {
return this._super(store, type, 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, id), "DELETE");
}
});
示例中的电子邮件模型类似于:
The Email model in the example would be something like:
App.Email = DS.Model.extend({
address: DS.attr('string'),
alias: DS.attr('string'),
user: DS.belongsTo('user'),
parent: 'user'
});
