Breeze - How to Load Navigation property from cache -

i getting single entity using method fetchentitybykey, after loading navigation property entity entityaspect.loadnavigationproperty. loadnavigationproperty make call server, wondering if can first check cache, if exist there otherwise go server. how possible? here current code

  return datacontext.getprojectbyid(projectid)         .then(function (data) {               vm.project = data;              vm.project.entityaspect.loadnavigationproperty('messages');  }); 

here function encapsulated inside datacontext service.

 function getprojectbyid(projectid) {              return manager.fetchentitybykey('project', projectid)                 .then(querysucceeded, _queryfailed);              function querysucceeded(data) {                  return data.entity;             }         } 

also, how possible load navigation property limit. don't want have records navigation property @ once performance reason.

you can use entityquery.fromentitynavigation method construct query based on entity , navigationproperty . there can execute resulting query locally, via entitymanager.executequerylocally method. in example once have 'project' entity can following.

var messagesnavprop = project.entitytype.getproperty("messages"); var query = entityquery.fromentitynavigation(project, messagesnavprop); var messages = myentitymanager.executequerylocally(query); 

you can make use of the entityquery.using method toggle query between remote , local execution, this:

query = query.using(fetchstrategy.fromlocalcache); 

vs

query = query.using(fetchstrategy.fromserver);
