ember.js can't get pagination from metadata - ember.js

Question

I do an example like this,but still can't get pagination
this is my store.js.coffee
Eme.serializer = DS.RESTSerializer.create()
Eme.serializer.configure
meta: 'meta'
pagination: 'pagination'
Eme.CustomAdapter = DS.RESTAdapter.extend
serializer: Eme.serializer
namespace: "api/v1"
Eme.Store = DS.Store.extend
revision: 13
adapter: 'Eme.CustomAdapter'
this is my controller
Eme.PluginsController = Em.ArrayController.extend
content: []
pagination: (->
if this.get('model.isLoaded')
console.log #get('model.type')
console.log #get('store').typeMapFor(modelType).metadata
modelType = #get('model.type')
#get('store').typeMapFor(modelType).metadata.pagination
).property('model.isLoaded')
this is response
{
"meta":{
"pagination":{
"total_count":16,
"total_pages":2,
"current_page":1
}
},
"plugins":[{
"id":"1",
"name":"zhangsan",
}]
}
this is my log:
Eme.Plugin
Object {}

In the example you pasted, the modelType variable is output to console before it has been defined. That could be why you are not seeing the pagination data as expected.
I've created a jsbin with a slightly modified version of your code and it appears to output pagination data correctly. See: http://jsbin.com/anIKAfO/2/edit
App = Ember.Application.create({});
App.IndexRoute = Ember.Route.extend({
model: function(){
return App.Plugin.find();
}
});
App.IndexController = Ember.ArrayController.extend({
pagination: function() {
if (this.get('model.isLoaded')) {
var store = this.get('store');
modelType = this.get('model.type');
console.log('modeltype: ', this.get('model.type'));
var metadata = store.typeMapFor(modelType).metadata;
console.log('metadata: ', metadata);
return metadata.pagination;
}
}.property('model.isLoaded')
});
App.Store = DS.Store.extend({
adapter: 'App.Adapter'
});
App.Plugin = DS.Model.extend({
name: DS.attr('string')
});
App.serializer = DS.RESTSerializer.create();
App.serializer.configure({
meta: 'meta',
pagination: 'pagination'
});
App.Adapter = DS.RESTAdapter.extend({
serializer: App.serializer,
ajax: function(url, type, hash) {
console.log('App.Adapter.ajax:', url, type, hash);
json = App.RESTDATA[url];
if (json) {
console.log('App.Adapter.ajax: Found RESTDATA: ', json);
return new Ember.RSVP.Promise(function(resolve, reject) {
Ember.run(null, resolve, json);
});
} else {
console.log('App.Adapter.ajax: No RESTDATA for url, calling API', url);
return this._super(url, type, hash);
}
}
});
App.RESTDATA = {
'/plugins':
{
"meta":{
"pagination":{
"total_count":16,
"total_pages":2,
"current_page":1
}
},
"plugins":[{
"id":"1",
"name":"zhangsan"
}]
}
};
