问题 I have a route that displays a list of challenges, when I create a new challenge the record is persisted however the model of list of challenges is not updated when I transition back into the route. Is there something I am missing? //new.js var challenge = this.store.createRecord('challenge', { name_en: this.get('model.name_en'), name_fr: this.get('model.name_fr'), description_en: this.get('model.description_en'), description_fr: this.get('model.description_fr'), end_date: this.get('model.end

问题 I want to lock down my ember-cli project's version of ember-data to this commit, which updates the map function signatures and lets ED work with Ember 1.8.

问题 I have this JS bin. Does anyone know the reason why, when I modify the user model and click the button to rollback, why the firstName property is being rolled back but not the array custom attribute? Thanks. http://emberjs.jsbin.com/nunihuco/1/edit?html,js,console,output 回答1: Ember Data watches the property itself. The property itself isn't changing, your data inside is. You'd need to change the property for it to be able to rollback . this.set('model.listOfStuff', ['hello','world']); http:/

问题 There are select on the page for choosing country and it's need to save selected value in URL. I declared query params in route-driven controllers. It's all work! If country select is changed then url also changed. Demo: http://output.jsbin.com/releza But if I reload page with some valid GET params then it params convert to 'undefined'. For example, I try to load page http://output.jsbin.com/releza#/?country=2 and it redirect to http://output.jsbin.com/releza#/?country=undefined Why? # index

问题 What is the ember-cli best practice to deleteRecord() on a model that belongsTo multiple models? Do I have to manually clean up relationships on the parents? Migrating from ember to ember-cli I am having new trouble with deleteRecord() for a model 'star' that belongsTo multiple models, 'post' and 'user'. Before moving to ember cli it was working with this solution. The previous solution's delete action fails in the current ember-cli with errors and never calls the api . TypeError: Cannot read
