问题 I’m trying to set up my template so it displays approved , disapproved and all photos, based off a boolean in my model. These routes all use the same main outlet in the application.hbs file (referenced below). These routes are working all fine, except when I go from photos → approved/disapproved → photos . In other words, when returning back to photos from either approved or disapproved , the outlet is blank (with no console errors). Refreshing the page brings it back again. Here’s how my

问题 I have a User model that hasMany Reminders . When a User is first created, I want the reminders to be embedded. When it is updated, I don't want its reminders to be embedded. How can I do this? My strategy was to create a custom new-user-serializer that had DS.EmbeddedRecordsMixin and reminders: { embedded: 'always' } and use that in my UserAdapter s createRecord method, but I couldn't get it working. 回答1: It's not ideal, but you can do it - `import DS from 'ember-data'` `import

问题 I think data relationships are saved in the adapters of the Ember app. So the way the REST adapter, the local storage adapter, and the fixture adapter saves relationships might be all different. Relationships might be saved in the parent or the child. I would like to know how each adapter saves relationships. Source code and examples would be appreciated. I'll update with my findings as well. 来源： https://stackoverflow.com/questions/17688671/how-are-relationships-saved-in-the-popular-ember-js

问题 I am using Ember-Data (v1.13.13) to manage objects coming from the server. The value of an incoming attribute is null. The attribute type is a string with default value being an empty string. The null is not defaulting to the empty string as expected. So it looks like Ember-Data establishes a nullable string data type by default (thinking about it in general terms, not a JavaScript thing, of course). In any case, I would like to know how to convert the incoming null to the default empty

问题 Considering something similar to the example outlined here: App.Router.map(function() { this.resource("posts", function() { this.resource("post", { path: "/posts/:post_id" }, function() { this.resource("comments", { path: "/comments" }); }); }); }); using the DS.RESTAdapter . The Router would load all the posts when I access the PostsRoute with a call to the API URL /posts . When I then access PostRoute , for example for the post with id=1 , it doesn't hit the API again, i.e. it doesn't hit

问题 I'm using ember-data , I call to my API using this.store.findAll('environment').then(function(values){ //1 },function(reason){ //rejected }); And my code does go into the //1, problem is I get this object which seems pretty invalid. Here is what my api sends back. { "data": { "environments": [ { "id": 1, "localePath": "C:\\XML_DEPOT", "name": "Acceptation 1", "remotePath": "D:\\XML_DEPOT", "databaseServerName": "blabla", "databaseName": "blabla", "port": 60903 }, { "id": 2, "localePath": "bob

问题 I have a basic Ember app and I am trying to handle validation errors on save (model is using the REST Adapter). In my route I am doing: task.save().then( function() {alert("success");}, function() {alert("fail");} ).catch( function() {alert("catch error");} ); When the record is valid I get the "success" alert, but when record is invalid, I do not get the "fail" alert OR "catch error". In the console I get: POST http://localhost:8080/api/tasks 422 (Unprocessable Entity) Error: The adapter
