我正在从Ember数据0.13迁移到1.0.0 beta.根据doc
https://github.com/emberjs/data/blob/master/TRANSITION.md,现在有每种类型的适配器和每种类型的序列化器.
这意味着我无法再使用主键和身份验证的某些特定覆盖来定义“myRestAdapter”.我现在需要为每个模型类型实现此代码,从而导致复制相同代码的xx倍.
Ember数据中的代码0.13：
App.AuthenticatedRestAdapter = DS.RESTAdapter.extend({
serializer: DS.RESTSerializer.extend({
primaryKey: function() {
return '_id';
}
}),ajax: function (url,type,hash) {
hash = hash || {};
hash.headers = hash.headers || {};
hash.headers['Authorization'] = App.Store.authToken;
return this._super(url,hash);
}
});
Ember数据1.0.0中的代码(仅用于将主键设置为_id而不是_id：
App.AuthorSerializer = DS.RESTSerializer.extend({
normalize: function (type,property,hash) {
// property will be "post" for the post and "comments" for the
// comments (the name in the payload)
// normalize the `_id`
var json = { id: hash._id };
delete hash._id;
// normalize the underscored properties
for (var prop in hash) {
json[prop.camelize()] = hash[prop];
}
// delegate to any type-specific normalizations
return this._super(type,json);
}
});
我是否理解我需要为每个需要_id作为主键的模型复制同一个块？是否已经没有办法为整个应用程序指定一次？
解决方法
由于代码接缝是类型不可知的,为什么你不只是创建模型可以扩展的自定义序列化器,例如：
App.Serializer = DS.RESTSerializer.extend({
normalize: function (type,hash,property) {
// property will be "post" for the post and "comments" for the
// comments (the name in the payload)
// normalize the `_id`
var json = { id: hash._id };
delete hash._id;
// normalize the underscored properties
for (var prop in hash) {
json[prop.camelize()] = hash[prop];
}
// delegate to any type-specific normalizations
return this._super(type,json,property);
}
});
然后对所有模型使用App.Serializer：
App.AuthorSerializer = App.Serializer.extend(); App.PostSerializer = App.Serializer.extend(); ...
希望能帮助到你.
